Naked Ladies run wild in my backyard. Over the years they have been split up, moved about, and even reseeded until now they seem to pop up just about anywhere.
Amaryllis belladonna is known by the common name "Naked Lady" because it sends up large, fragrant pink flowers while the plant is still naked (without leaves). This usually occurs in late summer. Leaves will follow in the fall.
Amaryllis belladonna is native to western South Africa and grows in a Mediterranean climate (warm, dry summers and cool, wet winters). This climate is found in and around the Mediterranean sea, the southwestern coasts of Africa, Australia, Chile, and North America. To grow Amaryllis belladonna successfully you need a fair amount of warmth and dryness in the summer — they are reliably hardy down to about 15F (-9C).
