a suggestion: look up FLOWER HILL FARM in Boonville NY. This gal is amazing. Flowers are her thing. she grows and sells gorgeous bouquets. this should give you more ideas. don't forget astilbe. a reliable perennial for spring cutting with forsythia and pussy willows. and don't let the roses boss you around.my husband-who knew absolutely nothing about growing anything-had a rose garden that was the envy of the neighborhood. 21 different roses. just heavenly.
