Cypella Coelestis - New Crop Summary & Recommendations Cypella coelestis - New Crop Summary & Recommendations By Ian Kirkegaard 2012 Series: New Floricultural Crops: Formulation of Production Schedules for Wild, Non- domesticated Species Part of the requirements for Horticultural Science 5051: Plant Production II University of Minnesota Ian Kirkegaard New Crops Report HORT 5051 Cypella coelestis New Crop Report Taxonomy: Cypella coelestis is an herbaceous perennial in USDA zones 8b-10b (15-35 degrees F). It is from the Iridaceae family and has been known as Phallocalis coelestis, as well as Cypella plumbea. In Australia it is known as Herbertia platensis or commonly as the Blue Tiger Iris. The common name of Cypella coelestis in North America is the Goblet Flower. Geographic Distribution: Cypella coelestis is native to South America, more specifically Brazil, Argentina, and Uruguay. It has been introduced to North America and is currently represented on all coasts of the U.S. Groups of these flowers have successfully been grown in California, Florida, North and South Carolina, Texas, Virginia and Washington. There is some potential for Cypella coelestis to become invasive as this plant spreads though rhizomes. No problems have been reported thus far. Native Habitat: Cypella coelestis is generally found clumping on open woodland and open grassland margins. It has average water needs. Water regularly, be sure not to over water. Taxonomic Description: Cypella coelestis is an herbaceous monocot with an erect habit. When it reaches maturity it usually reaches between 2 and 3’ tall, with flower stalks reaching about 3 ½’ tall. The leaves are spear like and overlap, giving an appearance similar to that of a fan. One should be careful when trimming back floral stalks. Once all of the blooms have ceased, it is common that a floral stalk will set more blooms if given a couple of weeks. Cypella coelestis flowers in clumps topped with blue, goblet-shaped flowers on a sturdy but airy 3’ stem. Each flower has six petals: three large blue-lavender ones, and three tricolor ones of white, yellow, and blue. Although each flower only lasts one day, the succession of flowers will provide color for several months. Flowers bloom in mid- summer. It uses bulbs as underground storage structures and can be used for propagation too. Bulb scales are richly colored burnt-orange and are much more delicate that they appear. Name and Description of Varieties/ Cultivars on the Market: There is much confusion about the taxonomic name of this plant. In Australia, it’s known as Herbertia platensis and is sold as the ‘Blue Tiger Iris’. This plant is identical to the plant we, in the U.S., call Cypella coelestis. There is only one known cultivar of this species and it is referred to as the ‘Goblet Flower’. Propagation Methods: I was unable to locate any mention of vegetative propagation of Cypella coelestis. This project was focused on seed propagation. I started with sixty seeds of Cypella coelestis. Their origin was unknown. Since there were small amounts of information concerning the germination of Cypella coelestis, I decided to split my seeds into two treatments. The treatments were designed to test the most basic of germination requirements. Did the seed require light to germinate? To test this I placed the sixty seeds into a 128-plug tray with standard germination mix as the media. I then covered thirty of the seeds liberally with vermiculite to simulate an attempt to germinate below the surface of the soil. The other thirty seeds were placed on top of the soil in direct light. The two treatments were placed into the mist house at around 70 degrees Fahrenheit until germination. The recommendations were to propagate this plant by bulb. Any information about the germination of Cypella coelestis said that germination from seed would take anywhere from 2-9 weeks. I had 0% germination for the first three weeks. In week four, three seedlings from the light treated group germinated. I did not see germination from the light-free treatment for five weeks. Within seven weeks, 85% germination was achieved. No more seedlings germinated after seven weeks. All but one seedling from the light treated group germinated. The other eight seeds were apart of the light-free treatment. Once germination reached its maximum, I transplanted the seedlings into four groups. Two identical groups were formed from each treatment, making 4 total test groups. Two groups were grown in standard LC-8 growing mix. The other two were grown in a mixture of LC-8 media and sand with a 1:1 ratio. This was designed to test optimum growth requirements for C. coelestis following germination. Unfortunately, after seven weeks of germination, there was very little time to see indicative results of the second experiment. I did notice that the plants in the media mixture (1:1, Sand: LC-8) did not grow as large as the seedlings in straight LC-8. I believe this was due to the lack of water holding capacity within the sand. From weeks eight and on, there were little changes to speak of. No flowers were produced, and none of the plants reached a height of over 6” by the conclusion of the experiment. In summation, Cypella coelestis will germinate in 14-49 days in warm (70 F) conditions. Production Specification: The best form of Cypella coelestis for marketing purposes is an erect plant roughly 2’ tall with multiple flowers per stalk. An ideal variety would germinate in under thirty-five days. Market Niche: The current market for this plant is as a rare and unusual plant. I don’t find this plant unusual, but it is somewhat rare. Since it flowers throughout the summer, I think it would be a great plant to be sold in potted form as it could help the blooming time last longer. Iris’ are already sold commonly to plant consumers, so they’re familiar with its shape. This not-so-commonly-known species of this common plant family could be a good winner since it would be something fairly new to most consumers. I don’t believe Cypella coelestis has potential as a cut flower. All of the flowers bloom in succession of one another. After the top bloom dies, a new one persists from below the last one filling its spot at the stop of the stem. Since the one flower is only open for one day, I think cutting the stalk from with each new flower grows would be a bad idea. This flower must be enjoyed when it is growing. Production Schedule (From Seed): Seeds should be sown in week one. Since a concrete germination time is not known, this plant will need all the time it can get if you want to be able to sell them by mother’s day. The seeds should germinate within four weeks with good luck and will remain in the plug stage for another two weeks until the first true leaf is seen. After that, plants can be transplanted into 4½” round, geranium pots in LC-8 media. Blooms should be seen by July. No information exists on forcing Cypella coelestis. The recommendations are to grow this plant from bulb as the seeds take a notoriously long time to germinate. Needs Assessment for Genetic Improvement: A definitive area for improvement is the germination time. This plant would not have much success germinating at this rate in any market. I think work can also be done crossing this species with other species of Iris to produce new cultivars with new colors and patters. Works Cited Pittman, J. (2010). Cypella coelestis.

Luther Burbank (1849–1926) was a prolific ornamental plant breeder, who worked with 91 genera of ornamentals, from Abutilon to Zinnia, and released nearly 1000 cultivars to the industry. His innovative work included both herbaceous and woody plant materials as well as ornamental vegetables such as corn, tomatoes, and spineless cacti. His most popular ornamental release, the shasta daisy hybrids—first released in 1901, is still on the global market. This article focuses on Luther Burbank’s breeding techniques with ornamental plants and how both the germplasms that he developed and his methodologies used permeate modern flower breeding. Genera with the highest number of cultivars bred and released by Burbank include Amaryllis, Hippeastrum, and Crinum followed by Lilium, Hemerocallis, Watsonia, Papaver, Gladiolus, Dahlia, and Rosa. With Lilium, he pioneered breeding the North American native lily species, particularly those from the Pacific coastal region, producing the eponymous Lilium 3burbankii. Burbank’s breeding enterprise was designed to be self- sustaining based on profits from selling the entire product line of a new cultivar or crop only to wholesale firms, who then held exclusives for propagation and selling, although financial hardships necessitated selling retail occasionally.

Meerow2 Herbs perennial, rarely shrubby or treelike, often with bulbs, corms, rhizomes, or tubers. Leaves basal or cauline, often narrow, margin entire or spiny. Inflorescence a terminal spike, umbel, raceme, panicle, or flowers solitary. Flowers bisexual, actinomorphic or zygomorphic, usually subtended by 1 to several spathaceous involucres. Perianth segments 6, in 2 whorls, free or connate to form a short tube, with or without a corona. Stamens 6, inserted at perianth throat or at base of segments; filaments sometimes basally con- nate; anther dorsifixed or basifixed, mostly introrse. Ovary inferior, 3-loculed; ovules few to many per locule; placentation axile. Style slender; stigma capitate or 3-lobed. Fruit a capsule, usually loculicidal, sometimes dehiscing irregularly, rarely a berry. Seeds with endosperm. More than 100 genera and 1200 species: tropical, subtropical, and temperate regions worldwide; ten genera and 34 species (14 endemic, four introduced) in China. The circumscription adopted here for Amaryllidaceae sensu lato follows FRPS and is not supported by current phylogenetic analysis of the group. The genus order has been slightly adjusted to reflect the more recent classification of Kubitzki (Fam. Gen. Vasc. Pl. 3, 1998), who placed the genera in segregate families as follows: Acanthochlamydaceae: Acanthochlamys; Agavaceae: Agave; Amaryllidaceae: Crinum, Lycoris, Narcissus, Pancratium, Zephyranthes; Hypoxidaceae: Curculigo, Hypoxis; Ixioliriaceae: Ixiolirion. Many members of this family, including garden plants, are cultivated in China as ornamentals, including Clivia Lindley, Haemanthus Linnaeus, Hippeastrum Herbert, Hymenocallis Salisbury, Leucojum Linnaeus, Polianthes Linnaeus, and Sprekelia Heister; however, not all are described in this account.

  • Rare Vascular Plant Taxa Associated with the Longleaf Pine Ecosystems: Patterns in Taxonomy and Ecology
    Rare Vascular Plant Taxa Associated with the Longleaf Pine Ecosystems: Patterns in Taxonomy and Ecology Joan Walker U.S.D.A. Forest Service, Southeastern Forest Experiment Station, Department of Forest Resources, Clemson University, Clemson, SC 29634 ABSTRACT Ecological, taxonomic and biogeographical characteristics are used to describe the group of 187 rare vascular plant taxa associated with longleaf pine (Pinus palustris) throughout its range. Taxonomic and growth form distributions mirror the patterns of common plus rare taxa in the flora. Most of the species have rather narrow habitat preferences, and narrow geo­ graphic ranges, but a few rare sp~cies with broad habitat tolerances and wider geographic ranges are identified. Ninety-six local endemics are associated with longleaf pine ecosystems. This incidence is as high as in other comparably-sized endemic-rich areas in North America. A distinct geographic trend in rare species composition is indicated. Species fall into 4 groups: Florida longleaf associates, south Atlantic coastal plain, east Gulf coastal plain, and west Gulf coastal plain species. Distributional factors that produce rarity must be considered in the development of conser­ vation strategies. Overall, conserving longleaf communities rangewide will protect .large ~ numbers of rare plant taxa in Southeastern United States. INTRODUCTION 1986), and inevitably the strategies required to con­ serve them will differ. Recently Hardin and White (1989) effectively focused conservationists' attentions on the high The purposes of this study are to (1) identify numbers of rare species associated with wiregrass the rare species associated with longleaf pine eco­ (Aristida stricta), a grass that dominates the ground systems rangewide; (2) characterize the rare spe­ layer of longleaf communities through a large part cies taxonomically and ecologically, in order to of its range, and over a broad range of longleaf identify patterns that may distinguish this group habitats.
