Jacquemontia Reclinata Grown in Containers
REFEREED RESEARCH ARTICLE Shade limited root mass and carbohydrate reserves of the federally endangered Beach Photo by Joyce MaschinskiClustervine | Inset photo by Hannah Thorton Jacquemontia reclinata grown in containers ABSTRACT Anecdotal evidence suggested that germination and seedling Samuel J Wright and Matthew W Fidelibus | growth of the federally endangered beach clustervine (Jacque- montia reclinata [Convolvulaceae]) were best in the shade, but mature plants usually occur in coastal strand areas that are open or have low vegetation. We conducted an experiment using potted seedlings grown without shade, or under low, KEY WORDS moderate, or heavy shade enclosures. Shade did not affect revegetation, coastal strand, propagation, light shoot growth, or leaf or stem dry mass. Plants subjected to all levels of shade, however, had 40% to 70% less root dry NOMENCLATURE mass and about 50% lower root-to-shoot ratios than non- ITIS (2002) shaded plants. Moreover, the roots of non-shaded plants had 2 to 4 times more soluble sugars and starch than plants grown in shade. These findings suggest that when water and Figure 1.

Flowering of Watsonia Laccata As Influenced by Corm Storage and Forcing Temperatures ⁎ J.K
Available online at www.sciencedirect.com South African Journal of Botany 77 (2011) 631–637 www.elsevier.com/locate/sajb Flowering of Watsonia laccata as influenced by corm storage and forcing temperatures ⁎ J.K. Suh a, , J.H. Kim a, A.K. Lee a, M.S. Roh b a Dankook University, College of Bio-Resources Science, Department of Environmental Horticulture, Cheonan, Chungnam 330-714, Republic of Korea b US Department of Agriculture, Agricultural Research Service, National Arboretum, Floral and Nursery Plants Research Unit, Beltsville MD 20705, USA Received 24 March 2010; received in revised form 28 November 2010; accepted 22 December 2010 Abstract The genus Watsonia, belonging to the family Iridaceae, is comprised of about 50 species including W. laccata (Jacquin) Ker Gawler that flowers from September to November following low temperature and winter rainfall. Therefore, we hypothesized that flowering would be favored by forcing at low greenhouse temperatures. Using clonal W. laccata corms, four experiments were designed to investigate the effect of temperatures during corm storage, forcing, and their interaction on growth and flowering. Corm formation is favored by growing plants at 18°– 20°/15°–17 °C and 21°–23°/18°–20 °C, day/night temperatures. Flowering was earliest with corms produced at 24°–26°/18°–20 °C and forced at 18°–20/15°–17 °C, and was significantly delayed when forced at 27°–29°/24°–26 °C. Flowering was, however, favored by 2 or 4 weeks of high temperatures (27°–29°/24°–26 °C) prior to forcing at low temperatures (18°–20°/15°–17 °C). The number of florets was not significantly affected by corm storage, forcing temperatures, or their interaction, although forcing at high temperatures tends to reduce the floret number. -

Although this year has thrown many obstacles our way, we feel that the “show must go on.” In response to the COVID-19 situation, this year will look a little different. For the safety of our members and our customers, this year will be an online pre-order only sale. Our mission stays the same: to support our community’s green spaces, and to educate our community in the areas of gardening, horticulture, conservation, and related topics. GCH members serve as volunteers, and our profits from the Bulb Mart are given back to WELCOME the community in support of our mission. In the last fifteen years, we have given back over $3.5 million in grants to the community! The Garden Club of Houston’s first Plant Sale was held in 1942, on the steps of The Museum of Fine Arts, Houston, with plants dug from members’ gardens. Plants propagated from our own members’ yards will be available again this year as well as plants and bulbs sourced from near and far that are unique, interesting, and well suited for area gardens. -

After each item in the seed list you will find a number estimating the total number of seeds available. Donations with fewer than 100 seeds will most likely be sold out early. Be sure to check substitutes when ordering any of these seeds. They will D.Q! be used as substitutes. Seeds in short supply may be packed with as few as 4 seeds. If you want items with more seeds per packet, order items in greater supply. Please note the following abreviations used in the seedlist: H P means Hand Pollinated, coli. means Wild Collected, and ex. indicates that the plants that seeds were collected from were originally from another source (which may be a person, another seed exchange, or a wild location) which immediately follows the abbreviation. The alphabetical groups (A, B, C, etc.) used in the seed list follow the outline provided in the SIGNA Species Iris Study Manual published in 1972, e.g. sub-section Pogoniris, series Pumilae is under A, sub-section Pogoniris, series Intermedeae in under B and so on.
