Eustephia is a small genus of South American bulbs of the family Amaryllidaceae from southern Peru to Bolivia, where they grow in high altitude subtropical forests. The bulbs are summer-growing and dormant in winter. They can be grown like a hybrid Hippeastrum, keeping them dryish in winter. The flowers are tubular, pink to red with green tips to the tepals, somewhat resembling the flower of a Phaedranassa. Leaves are linear.
Eustephia darwinii is from Peru near Cuzsco; my bulbs produce their flower stems in the fall. Photos by Diana Chapman.
