The Plants of Manual THE PLANTS OF MANUAL Langley, April 2020 Welcome to Free Spirit’s Manual, 5th edition. This new edition of our manual came about sooner than we expected: we simply ran out of the last one in a hurry! We have taken this opportunity to incorporate the latest additions and changes. As always, we strive to bring you an assortment of performers that with a reasonable amount of knowledge and care, will thrive for you for years to come. Although a few trickier ones have snuck in, they are included with instructions. We hope that this manual will be a source of inspiration and help you to grow these plants even better than we do. The best way to see, touch and experience the plants is to visit the nursery in person. We look forward to seeing you. Lambert and Marjanne Vrijmoed Copyright © 2020 by Free Spirit Nursery Inc.

Plants are indicated with (3) behind the zone. Additional hardiness notes were provided by Cheri Sydor who has grown our plants in her and client’s gardens for up to 20 years. Her hardiness experience is indicated with (3b) or (4), unless planted in “unsuitable soil” where the plants will perish. Cheri: “Unsuitable soil in Calgary is often way too manured, over-watered and mulched with wet wood chips”. Thank you Cheri! Exposure: This is always a complex issue and exposure will vary across the diverse regions of our beautiful country. A knowledge of soil condition, precipitation, hot and cold spots, air movement (wind, drafts or the absence of air movement), humidity, altitude and latitude are all critical to ensuring the well being of your plants. All of the information we have shared here is based upon our experiences here in Langley, gardening in zone 6 on a gravelly soil that is amended with organic matter and top-dressed with a composted bark to preserve moisture, reduce weeds and improve the backdrop for the plants (all of those rocks can look pretty messy). Full sun [ ❍ ] Plants should receive at least 7 hours of direct sunlight per day, including the hot afternoon sun between noon and 4:00 pm. This typically occurs in an open meadow or on the south side of a building. Full sun to part sun [ ❍ ◗ ] Plants will tolerate hot afternoon sun, as well as some shade, but in the Pacific Northwest plants perform best with at least 3 hours of direct sunlight during the hottest part of the day. Part sun to bright shade [ ◗ ● ] Plants will tolerate direct sunlight for part of the day but are happiest when out of the hot afternoon sun. Deciduous shade, dappled light or filtered light is ideal for these plants. Most woodland plants fall into this category. Shade [ ● ] Plants should receive no direct sunlight for most of the growing season. The areas to grow these plants include the north side of a structure, like a wall or a fence and beneath the canopy of a tree (deciduous or evergreen). Some early morning (until 9:00 am in the summer) or late afternoon sun (after 8:00 pm) can be tolerated but is not required. You will find that most of these plants will show their best under brighter conditions. A distinction should be made between dense, dark shade and bright, open shade. For example, all shade plants will grow fine on the north side of a home or along a tree belt without neighbouring structures or trees, where it is bright but there is no direct sunlight. But if, at this same north side, there were evergreen trees creating a high overhead canopy, so that you could barely see sky when you looked up, only certain plants would be able to grow well there. Similarly, your choice of plants would be limited beneath the canopy of an evergreen tree with draping, wide-spreading branches. Add to that a dense system of tree roots and the choices become slim. -2- A number of plants have earned one or more of the following accolades: AGM: Award of Garden Merit, administered by the RHS Wisley in the U.K. recommending outstanding plants for garden use. GPP: Chosen a Great Plant Pick by a selection committee organized and administered by the Elisabeth C. Miller Botanical Garden in Seattle, recommending outstanding plants for the Pacific Northwest. PPA (1992): Perennial Plant Association, “Perennial Plant of the Year” with the year listed between brackets. PERENNIALS ACHILLEA (Asteraceae) yarrow Achilleas prefer a freely draining soil and a sunny location in the garden to insure longevity. Make sure that the sunlight can penetrate to the leaves at ground level by keeping neighbouring plants in check. If plant vigour declines, lift them out of the ground in early spring, divide and replant only the outside parts of the clumps, composting the centers. We find yarrow invaluable for its horizontal flower shape and long season of interest, which extends through winter. We have enjoyed all of the following selections for a number of years, with a minimum of fuss. ‘Credo’ Z3 yellow 120 cm x 50 cm ❍ June-Sept Sulphur-coloured flowers. Good winter silhouette, strong stems. filipendulina —‘Parker’s Variety’ Z4 yellow 100 cm x 50 cm ❍ July Golden yellow plates on tall stems. Excellent for cutting. Grey-green foliage in low clumps. Long lived. ‘Moonshine’ Z3 sulphur 60 cm x 50 cm ❍ June-Sept A hybrid raised by Alan Bloom in 1954 and still going strong! Pretty silvery grey foliage combines perfectly with the sulphuric yellow flowers. A great cut flower and a reliable repeat bloomer if clipped back right after its first show. GPP ‘Red Velvet’ Z3 red 80 cm x 50 cm ❍ June-Sept Stands out as the darkest red achillea we have ever grown. A beautiful vibrant colour. ‘Walther Funcke’ Z3 or-red 70 cm x 50 cm ❍ June-Sept Like all of the above cultivars, a non-invasive yarrow. This is basically a shorter version of A. ‛Feuerland’, adding hot flavour to the border. The gray-green foliage combines nicely with the flowers. ACHLYS (Berberidaceae) vanilla leaf W. N. America triphylla Z5 (3) white 35 cm x ∼∼ ◗ ● April-May BC native. Slowly colonizes in even the darkest shade. The wonderful tender-looking, three-parted, bright green leaves are a great textural addition to the shade garden. The flowers appear in dense short spikes above the leaves. Vanilla leaf loves to move its stolons through duff in the shade of deciduous or evergreen trees. Established plants seem to be unaffected by slugs and will continue to delight throughout the growing season. Deciduous. ACONITUM (Ranunculaceae) monkshood x cammarum — ‘Bicolor’ Z4 blue-white 140 cm x 50 cm ❍ ◗ June-July Requiring some mild staking on our (sandy) soil but lovely, like they are hand-painted, blue and white hoods. All parts of any monkshood are poisonous. AGM and GPP carmichaelii — ‘Barker’s Variety’ Z4 blue 140 cm x 40 cm ❍ ◗ Sept-Oct A highlight of our late fall borders. Long flower stems and just plain cool looking in the late summer sun. Excellent for cutting as well. GPP -3- napellus — ‘Bergfürst’ Z4 (3) blue 120 cm x 50 cm ❍ ◗ June-July Dark, purple-blue flowers in long, loose spikes appear on stiff, upright stems in early summer. The stems are cloaked with glossy, dark green leaves, divided into narrow, linear lobes. Dies back by late summer, so it is best placed in the middle or back of a border. — ‘Grandiflorum Album’ Z4 (3)white 130 cm x 60 cm ❍ ◗ June-July Our original plants came back with us from Piet and Anja Oudolf’s nursery many moons ago. It is a pretty and upright form showing green buds and pure white blossoms. seoulense Z5 blue 150 cm x 50 cm ❍ ◗ August-Sept A surprising appearance in early spring with the orange-red emerging shoots. Upright in habit and displaying its striking blue blossoms in August. Staking might be required. septentrionale — ‘Ivorine’ Z4 (3) white 50 cm x 40 cm ❍ ◗ May This short and compact monkshood carries ivory-white flowers on sturdy stalks. The plants die back shortly after flowering, allowing later blooming plants to take its place. In our garden these later performing neighbours are Corydalis elata and Euphorbia corollata. ACORUS (Araceae) dwarf sweet flag gramineus Japan, E. Asia — ‘Variegatus’ Z6 25 cm x 30 cm ❍ ◗ Forms low, evergreen, dwarf iris-like clumps. Nice with woodland anemones and epimediums. Prefers a moisture-retentive soil but is equally happy in sun as in more shady conditions. — ‘Minimus’ Z6 10 cm x 20 cm ◗ ● Same growing conditions as the species but with bright green foliage in dense, low spreading clumps.

  • Staminal Evolution in the Genus Salvia (Lamiaceae): Molecular Phylogenetic Evidence for Multiple Origins of the Staminal Lever
    Staminal Evolution In The Genus Salvia (Lamiaceae): Molecular Phylogenetic Evidence For Multiple Origins Of The Staminal Lever Jay B. Walker & Kenneth J. Sytsma (Dept. of Botany, University of Wisconsin, Madison) Annals of Botany (in press) Abstract • Background and Aims - The genus Salvia has traditionally included any member of the tribe Mentheae (Lamiaceae) with only two stamens and with each stamen expressing an elongate connective. The recent demonstration of the non-monophyly of the genus presents interesting implications for staminal evolution in the tribe Mentheae. In the context of a molecular phylogeny, we characterize the staminal morphology of the various lineages of Salvia and related genera and present an evolutionary interpretation of staminal variation within the tribe Mentheae. • Methods. Two molecular analyses are presented in order to investigate phylogenetic relationships in the tribe Mentheae and the genus Salvia. The first presents a tribal survey of the Mentheae and the second concentrates on Salvia and related genera. Schematic sketches are presented for the staminal morphology of each major lineage of Salvia and related genera. • Key Results. These analyses suggest an independent origin of the staminal elongate connective on at least three different occasions within the tribe Mentheae, each time with a distinct morphology. Each independent origin of the lever mechanism shows a similar progression of staminal change from slight elongation of the connective tissue separating two fertile thecae to abortion of the posterior thecae and fusion of adjacent posterior thecae. We characterize a monophyletic lineage within the Mentheae consisting of the genera Lepechinia, Melissa, Salvia, Dorystaechas, Meriandra, Zhumeria, Perovskia, and Rosmarinus. • Conclusions.

(Lamiaceae) species are used by many people in various villages and towns for the therapeutic value of their essential oils. Salvia dichroantha Stapf is an endemic plant of the Irano-Turanian phytogeographic region. Plant materials were collected during the flowering period from Konya Cihanbeyli (900 m) and Konya Taşkent (1800 m). In this study, water-distilled essential oil of Salvia dichroantha was analyzed. The analysis was performed by using a gas chromatography (GC-FID) and gas chromatography- mass spectrometry (GC-MS) systems, simultaneously. Eight compounds were identified from the oil of Taşkent representing 96.2 % of the total oil and nine compounds were identified from the oil of Cihanbeyli representing 98.3% of the total oil. The major components were found as caryophyllene oxide (38.6%), caryophyllenol I (16.7%), caryophyllenol II (15.6%) and caryophylladienol II (11.1%) for Taşkent; caryophyllene oxide (65.8%), caryophyllenol II (14.3 %) for the oil of Cihanbeyli.

  • Major Lineages Within Apiaceae Subfamily Apioideae: a Comparison of Chloroplast Restriction Site and Dna Sequence Data1
    American Journal of Botany 86(7): 1014±1026. 1999. MAJOR LINEAGES WITHIN APIACEAE SUBFAMILY APIOIDEAE: A COMPARISON OF CHLOROPLAST RESTRICTION SITE AND DNA SEQUENCE DATA1 GREGORY M. PLUNKETT2 AND STEPHEN R. DOWNIE Department of Plant Biology, University of Illinois, Urbana, Illinois 61801 Traditional sources of taxonomic characters in the large and taxonomically complex subfamily Apioideae (Apiaceae) have been confounding and no classi®cation system of the subfamily has been widely accepted. A restriction site analysis of the chloroplast genome from 78 representatives of Apioideae and related groups provided a data matrix of 990 variable characters (750 of which were potentially parsimony-informative). A comparison of these data to that of three recent DNA sequencing studies of Apioideae (based on ITS, rpoCl intron, and matK sequences) shows that the restriction site analysis provides 2.6± 3.6 times more variable characters for a comparable group of taxa. Moreover, levels of divergence appear to be well suited to studies at the subfamilial and tribal levels of Apiaceae. Cladistic and phenetic analyses of the restriction site data yielded trees that are visually congruent to those derived from the other recent molecular studies. On the basis of these comparisons, six lineages and one paraphyletic grade are provisionally recognized as informal groups. These groups can serve as the starting point for future, more intensive studies of the subfamily. Key words: Apiaceae; Apioideae; chloroplast genome; restriction site analysis; Umbelliferae. Apioideae are the largest and best-known subfamily of tem, and biochemical characters exhibit similarly con- Apiaceae (5 Umbelliferae) and include many familiar ed- founding parallelisms (e.g., Bell, 1971; Harborne, 1971; ible plants (e.g., carrot, parsnips, parsley, celery, fennel, Nielsen, 1971).

  • Ranunculus Ficaria (Ranunculaceae) Naturalized in Texas: Update
    Nesom, G.L. 2015. Ranunculus ficaria (Ranunculaceae) naturalized in Texas: Update. Phytoneuron 2015-27: 1–7. Published 29 April 2015. ISSN 2153 733X RANUNCULUS FICARIA (RANUNCULACEAE) NATURALIZED IN TEXAS: UPDATE GUY L. NESOM 2925 Hartwood Drive Fort Worth, Texas 76109 [email protected] ABSTRACT In the 7 years since a report of its naturalization along a creek in Tarrant County, Texas, Ranunculus ficaria (now treated within the genus Ficaria as F. verna ) has increased in number of plants and coverage at that locality. The Texas plants produce axillary bulbils and flowers apparently are sterile, producing only unexpanded achenes. Photos show population structure and characteristics of the habitat. Ranunculus ficaria L. was earlier observed (Nesom 2008) to be naturalized along Overton Creek within Overton Park in Fort Worth, Texas. It was noted that "Thirty discrete plants, clearly naturalized, grow in an area of about 30 square feet ... A second population of five scattered plants occurs on the stream terrace about 300 yards downstream." In 2015, areal coverage of plants of Ranunculus ficaria has increased by about 6 times; the original larger population has expanded, additional colonies have formed downstream between 20 and 50 yards from the original, and an additional large population has arisen downstream of plants seen in 2008, increasing the linear extent of the total population to about 400 yards. Photos of subgroups of the Overton Park population (Figs. 1–7) show the characteristic habitat and dispersion of the plants –– all are growing in wet soil immediately beside the water or close by on the low, frequently flooded terrace.

Description and Variation: As Post et al. (2009) outline, North American treatments of Ficaria verna did not include subspecies or only included one while European treatments include five subspecies: subsp. ficariiformis, subsp. chrysocephalus, subsp. calthifolius, subsp. ficaria, subsp. bulbilifer. Through a review of herbarium specimens, Post et al. (2009) determined that all five subspecies existed here in the United States. Sell (1994) provides descriptions of all five subspecies. Whittemore (1997) states that the species is highly variable and that the different forms intergrade extensively and varieties are often impossible to distinguish. Listing Ficaria verna as a Class C noxious weed includes all subspecies of F. verna and any cultivars of the species and subspecies. Overall Habit: Ficaria verna is a highly variable, glabrous perennial with tuberous roots.

  • Gymnaconitum, a New Genus of Ranunculaceae Endemic to the Qinghai-Tibetan Plateau
    TAXON 62 (4) • August 2013: 713–722 Wang & al. • Gymnaconitum, a new genus of Ranunculaceae Gymnaconitum, a new genus of Ranunculaceae endemic to the Qinghai-Tibetan Plateau Wei Wang,1 Yang Liu,2 Sheng-Xiang Yu,1 Tian-Gang Gao1 & Zhi-Duan Chen1 1 State Key Laboratory of Systematic and Evolutionary Botany, Institute of Botany, Chinese Academy of Sciences, Beijing 100093, P.R. China 2 Department of Ecology and Evolutionary Biology, University of Connecticut, Storrs, Connecticut 06269-3043, U.S.A. Author for correspondence: Wei Wang, [email protected] Abstract The monophyly of traditional Aconitum remains unresolved, owing to the controversial systematic position and taxonomic treatment of the monotypic, Qinghai-Tibetan Plateau endemic A. subg. Gymnaconitum. In this study, we analyzed two datasets using maximum likelihood and Bayesian inference methods: (1) two markers (ITS, trnL-F) of 285 Delphinieae species, and (2) six markers (ITS, trnL-F, trnH-psbA, trnK-matK, trnS-trnG, rbcL) of 32 Delphinieae species. All our analyses show that traditional Aconitum is not monophyletic and that subgenus Gymnaconitum and a broadly defined Delphinium form a clade. The SOWH tests also reject the inclusion of subgenus Gymnaconitum in traditional Aconitum. Subgenus Gymnaconitum markedly differs from other species of Aconitum and other genera of tribe Delphinieae in many non-molecular characters. By integrating lines of evidence from molecular phylogeny, divergence times, morphology, and karyology, we raise the mono- typic A. subg. Gymnaconitum to generic status. Keywords Aconitum; Delphinieae; Gymnaconitum; monophyly; phylogeny; Qinghai-Tibetan Plateau; Ranunculaceae; SOWH test Supplementary Material The Electronic Supplement (Figs.

  • The Chromosome-Based Lavender Genome Provides New Insights Into
    Li et al. Horticulture Research (2021) 8:53 Horticulture Research https://doi.org/10.1038/s41438-021-00490-6 www.nature.com/hortres ARTICLE Open Access The chromosome-based lavender genome provides new insights into Lamiaceae evolution and terpenoid biosynthesis Jingrui Li1,2, Yiming Wang 3,YanmeiDong1,2, Wenying Zhang1,2,DiWang1, Hongtong Bai1,KuiLi3,HuiLi1 and Lei Shi1 Abstract The aromatic shrub Lavandula angustifolia produces various volatile terpenoids that serve as resources for essential oils and function in plant-insect communication. To better understand the genetic basis of the terpenoid diversity in lavender, we present a high-quality reference genome for the Chinese lavender cultivar ‘Jingxun 2’ using PacBio and Hi-C technologies to anchor the 894.50 Mb genome assembly into 27 pseudochromosomes. In addition to the γ triplication event, lavender underwent two rounds of whole-genome duplication (WGD) during the Eocene–Oligocene (29.6 MYA) and Miocene–Pliocene (6.9 MYA) transitions. As a result of tandem duplications and lineage-specific WGDs, gene families related to terpenoid biosynthesis in lavender are substantially expanded compared to those of five other species in Lamiaceae. Many terpenoid biosynthesis transcripts are abundant in glandular trichomes. We further integrated the contents of ecologically functional terpenoids and coexpressed terpenoid biosynthetic genes to construct terpenoid-gene networks. Typical gene clusters, including TPS-TPS, TPS- CYP450, and TPS-BAHD, linked with compounds that primarily function as attractants or repellents, were identified by fl 1234567890():,; 1234567890():,; 1234567890():,; 1234567890():,; their similar patterns of change during ower development or in response to methyl jasmonate. Comprehensive analysis of the genetic basis of the production of volatiles in lavender could serve as a foundation for future research into lavender evolution, phytochemistry, and ecology.
