Siberians are easily grown in most of the United States, hardy and relatively maintenance free. Their graceful foliage and sturdy stems are naturally attractive even when not in bloom. They do prefer wet conditions, but are not suited for ponds. The blooms are most commonly blue, violet, white, pink and yellow, with large falls and smaller standards. They are most attractive in established clumps and grow to a height of 2 to 4 feet.
