Number 3, Spring 1998 Director’S Letter
Planning and planting for a better world Friends of the JC Raulston Arboretum Newsletter Number 3, Spring 1998 Director’s Letter Spring greetings from the JC Raulston Arboretum! This garden- ing season is in full swing, and the Arboretum is the place to be. Emergence is the word! Flowers and foliage are emerging every- where. We had a magnificent late winter and early spring. The Cornus mas ‘Spring Glow’ located in the paradise garden was exquisite this year. The bright yellow flowers are bright and persistent, and the Students from a Wake Tech Community College Photography Class find exfoliating bark and attractive habit plenty to photograph on a February day in the Arboretum. make it a winner.

Relationships Within Cornales and Circumscription of Cornaceae—Matk and Rbcl Sequence Data and Effects of Outgroups and Long Branches

Various combinations of outgroups were assessed for their suitability and the effects of long branches and outgroups on tree topology were examined using RASA 2.4 prior to conducting phylogenetic analyses. RASA identified several potentially problematic taxa having long branches in individual data sets that may have obscured phylogenetic signal, but when data sets were combined RASA no longer detected long branch problems. tRASA provides a more conservative measurement for phylogenetic signal than the PTP and skewness tests. The separate matK and rbcL sequence data sets were measured as the chloroplast DNA containing phylogenetic signal by RASA, but PTP and skewness tests suggested the reverse. Nonetheless, the matK and rbcL sequence data sets suggested relationships within Cornales largely congruent with those suggested by the combined matK–rbcL sequence data set that contains significant phylogenetic signal as measured by tRASA, PTP, and skewness tests. -
Climbing Hydrangeas and Their Relatives
ARNOLDIA A continuation of the BULLETIN OF POPULAR INFORMATION of the Arnold Arboretum, Harvard University VOLUME ~4 JUNE 12, 1964 NUMBERS 4-5 CLIMBING HYDRANGEAS AND THEIR RELATIVES climbing habit is relatively rare in the family Saxifragaceae, the majority THE-M- of the species being shrubs, All the climbing species, which are found in four genera, Hydrangea Linnaeus (hereafter abbreviated as L.), Schizophragma Siebold & Zuccarini, Decumaria L., and Pileostegia Hooker & Thomson, utilize the same method of climbing, i.e., attachment to a supporting substrate by means of fine rootlets arising directly from the upright stems (a method of climbing similar to that of poison ivy, Rhus toxicodendron L. ). In nature, climbing is ac- complished on tree trunks, which implies that the plants are adapted, of neces- sity, to growing under conditions of low light intensity. This combination of peculiar characteristics enhances the horticultural possibilities of these plants by permitting the growth of fine specimens on shaded walls or trees. The beauty of the foliage of plants grown under such conditions (not to mention the relative freedom from insect damage) is reason enough to warrant the serious considera- tion of the homeowner. Moreover, in many of the species, showy inflorescences add to the beauty of the plants to such a degree that one wonders why they have not been more widely grown. The family Saxifragaceae has yielded many plants with extensive horticultural uses. Certain genera, such as Astilbe Buchanan-Hamilton, Deutzia Thunberg, Heuchera L., Hydrangea L., Philadelphus L., and Ribes L., have found particular favor because of their great variety and the relative ease with which they may be grown. -

Propagation of Ornamental Trees, Shrubs, and Woody Vines
M20_DAVI4493_08_SE_C20.qxd 8/18/10 8:36 PM Page 774 20 Propagation of Ornamental Trees, Shrubs, and Woody Vines INTRODUCTION Ornamental trees, shrubs, and woody vines are perennial plants. A few ornamental shrubs and vines are used as annuals and planted in land- scapes for one season in hardiness zones where they will not survive win- ter temperatures. This chapter describes propagation systems that include seed, cuttings, grafting, and micropropagation where appropri- ate for the listed species. Extensive references are included for more in-depth details of propagation. As a general rule, shrubs and vines are propagated by cuttings, whereas trees are produced by seed or selected cultivars grafted onto seedling rootstocks. There are exceptions, such as tree species that can be propagated by cuttings or micropropagated. In any commercial propagation system it is important to conduct small trials before propagating on a large scale. The propagation tech- niques and references listed are to serve as a guide. Propagators must develop their own procedures and chemical treatments that work best for their particular propagation systems. Abelia xgrandiflora. Abelia, Glossy Abelia. Commercially propagated with semi-hardwood cuttings. Can be rooted easily under mist in spring, summer, or fall. Rooting is enhanced by applying talc or quick-dips of 1,000 to 2,000 ppm IBA, or IBA-NAA combinations totaling 1,000 to 2,000 ppm have produced superior results (131). Hardwood cuttings also may be rooted in fall or late winter but less successfully than with semi-hardwood cuttings. Abelia is commercially micropropagated. Abies spp. Fir. Seed. Seed propagation is not difficult, but fresh seed should be used, since most species lose their viability after 1 year in ordinary storage.
