Bare root bulbs; shipped Oct. thru mid May. According to literature only growing 8-18", it did start blooming at 8" tall, rather "cute" looking. 4 years later it was 30" tall and the otherwise small flowers were quite substantial. Did I mention the leaves? Gorgeous clean-lush-green composed of 5-11 leaflets, becoming bigger by the year as well. Easy in a well drained soil, tolerates more sun than others. These are extra large, 3-4 year old corms.
