Cyrtanthus obliquus (Knysna lily) An evergreen plant with a large fleshy bulb about the size of an onion that holds strap-shaped upright gray-green leaves that can rise to 12 to 18 inches tall and often have a slight twist toward the rounded tip. In spring or summer appear the stout stalks rising to about the tips of foliage, as tall as 2 feet, topped by a large cluster with 7 to 12, 3-inch-long pendulous tubular orange flowers that flare out and turn yellow at the petal tips. Plant in full sun and water sparingly late spring through early fall. This unusual bulb comes from the winter-dry eastern cape region so soil must be very well drained and the bulb planted with a majority (two-thirds) exposed, particularly if grown outside in our mediterranean winter-rainfall climate. Allow the bulb to almost completely dry out between watering. Ultimate hardiness is not well known but likely it would be best to protect plants from frost. It may be possible to grow this plant in the ground if soil is well drained but likely this plant should be enjoyed as an interesting container plant. It comes from the coastal grasslands from KwaZulu-Natal to Humansdorp in the Eastern Cape Province where is can be found growing in well-drained soils on rocky slopes. It is reportedly the plant used as the floral emblem of the South African Institute of Parks Administration. The name Cyrtanthus comes from the Greek words 'kyrtos' meaning "curve" and 'anthos' meaning "flower" in reference to the curved perianth tube. The specific epithet obliquus means "slanting" or "blunt" and either refers to the way the leaves emerge from the bulb or to the rounded blunt leaf tips. This plant is usually listed with the common name Knysna lily from the location where it can be found (but this name is also used for Vallota purpurea) and other common names include Justifina, Soldier Lily and Sore-eye Flower. There is great information about this plant on the South African Botanic Garden Website This description is based on our research and observations made of this plant as it grows in our nursery, in the nursery garden and in other gardens that we have visited. We also try to incorporate comments received from others and appreciate getting feedback of any kind from those who have additional information about this plant, particularly if they disagree with what we have written or if they have additional cultural tips that would aid others in growing Cyrtanthus obliquus.
