WINNING PLANTS

Best bets for 2005

compiled byMEGHAN LYNCH

JANUARY ALWAYS BRINGS CHANGE: new calendars, new resolutions, and, from nurseries and breeders, new plant introductions. In the past, in this space, we’ve reported on new intros. For 2005, we’re trying something new. Every year, arboreta, botanic gardens, and plant societies (both national and regional) recognize certain plants through their award programs. These plants aren’t necessarily new, but they are noteworthy, having stood up to some tough competition and careful judges. In short, they represent the best of the best. Which is why—no matter what part of the country you live in, or what kind of plant interests you the most—you should resolve to try at least one in 2005.

ALL-AMERICA ROSE SELECTIONS

Since 1938. All-America Rose Selections, a nonprofit organization of rose growers and introducers, has judged roses on 15 characteristics, such as hardiness, color, vigor, and fragrance, for their annual award. Winners prove themselves over two-year trials in gardens across the country. This year’s selections are ‘About Face’, ‘DayDream’, ‘Elle’, and ‘Lady Elsie May’.

ALL-AMERICA SELECTIONS

All-America Selections, begun in 1932, aims to “promote new garden seed varieties with superior garden performance judged in impartial trials in North America.” Volunteer judges start seeds in side-by-side comparison trials and score plants on various qualities. Plants with the highest average scores win. This year’s flower winners are Gaillardia aristata ‘Arizona Sun’, Catharanthus roseus ‘First Kiss Blueberry’, and Zinnia elegans ‘Magellan Coral’; vegetable winners are Cucurbita maxima ‘Bonbon’ (winter squash), Eggplant F1 ‘Fairy Tale’, and Tomato F1 ‘Sugary’.

CARY AWARD

New England nursery professionals and members of the Worcester County Horticultural Society and Massachusetts Horticultural Society decide the Cary Awards; the Tower Hill Botanic Garden oversees the program. Winners in 2005 are Abies koreana (Korean fir), Syringa patula ‘Miss Kim’ (‘Miss Kim’ lilac), and Vaccinium angustifolium (lowbush blueberry).

GOLD MEDAL PLANTS
