We should have some smaller sized plants available at the nursery in 2020.
Chinese species that is a super great plant for the woodland garden and rock hardy in zone 5. Purple striped helmet shaped flower emerges in summer (think later than most) with glossy giant, 3-part leaves. If you peak inside the flower you will see the red spadix peeking back at you. A plant that when happy does form clumps over time and is very permanent in the open garden. Cannot say enough nice things about this one. Easy. Zone 5-9
