Flowering for the last several week is the South American (Argentina, Uruguay) iris family member, Cypella (Phallocallis) herbertii. The narrow foliage is almost invisible, so this gem can be tucked into any sunny spot for a splash of summer color. We have grown this for over three decades, and it never fails to perform. Hardiness is Zone 7a-9b.
Does it require sharp drainage?
No, typicaly soils without great drainage are fine.
