Cyrtanthus epiphyticus

Cyrtanthus epiphyticus, commonly known as the tree lily or hanging cyrtanthus, is a bulbous, summer-growing perennial reaching about 250 cm in height. The deciduous parts grow from the long-necked, ovoid bulb of up to 35 cm in diameter and covered in papery tunics.

Two broadly strap-shaped leaves are nearly flat to slightly channelled above and keeled below, tapering at both ends. Leaf dimensions are about 40 cm long and 15 cm wide, concurrent with flowering.

The species distribution is in the eastern extreme of the Western Cape, across the Eastern Cape and KwaZulu-Natal to the far south of Mpumalanga; also found in Lesotho and Swaziland.

The epiphytic plants, meaning that they don't necessarily require soil to grow in, are occasionally found on boulders, in rock crevices and on trees in moist places. The habitat population is deemed of least concern early in the twenty first century. 

The plants should do well in hanging baskets (Duncan, et al, 2016; Pooley, 1998; iNaturalist; http://redlist.sanbi.org).
