What conditions do they need to grow best? -B. G., Cincinnati, Ohio

A: Perennial chamomile, Cham­ aemelum nobile, is hardy in Zones 6 to 9. It prefers full sun but will tolerate a bit of shade. It likes a very well-aerated, rich but gritty and slightly acidic soil. It's hard to say why your plants died, since this plant is quite hardy and tolerant of most garden conditions. However, chamomile can fail to thrive when sub­ jected to extremes of dryness or moisture. If your soil is very heavy clay, which neither holds water well nor drains quickly when over-watered, your plants may have suf­ fered from both. Herbs are especially likely to die if waterlogged in winter. It is also possible that your chamomile was over fertilized and/or accidently sprayed with an Lilypons Water Gardens® herbicide.

At the Garden Club of America (GCA) "Show of Summer" at the Chicago Botanic , I Garden, also in june, the award went to l~ i "To the Prairies," sponsored by the Garden Club of Barrington (Illinois) and designed ~AmCf'ican and planted by Cinder Dowling and Susie JiOlt/culru raJ Rider. The design was seen as an ecologi­ &xi cally sensitive demonstration of the beauty that can be achieved by using plants native to the prairie. The award was presented by AHS member Violet Dawson, past presi­ dent of the GCA. At the Cincinnati Flower Show, the AHS Citation went to Mountain Laurel Nursery for its rendition of a cool, lush woodland retreat, featuring a quiet place to sit and contemplate a "weeping" rock wall in­ spired by those that seep spring water in the North Carolina mountains. The exhibits were chosen for best dem­ onstrating the bond between horticulture Fran Winslow hands out a membership brochure at the Cincinnati show. and the environment and inspiring viewers.
