Doryanthes palmeri (Giant Spear Lily) - Large clumping plant with many 8 foot long sword-like, flexible leaves. Summer-blooming large (to 4 inches wide) crimson-red flowers crown the top of flower stalks which barely rise out of the foliage at a diagonal angle to the ground and the flowers are followed by 4 inch long egg-shaped fruit. This plant does its best in full sun but it will tolerate some shade. It is drought tolerant, but they look best in a good deep soil with some irrigation. It is hardy to about 25-30 degrees F. A great plant for the garden or even as a container specimen in a large pot that requires very little maintenance to look good besides cutting off any browning senescing leaves and the spent flower spikes. Doryanthes palmeri has a restricted natural distribution in the McPherson Ranges of southeast Queensland and northeast New South Wales. The name for the genus comes from a combination of the Greek words 'doratos' which means "a spear" and 'anthos' meaning "flower" in reference to the long spear shaped inflorescence of Doryanthes excelsa. It was given this name in 1802 by the Portuguese priest, statesman, philosopher and botanist José Francisco Correia de Serra (1750–1823), who was a close friend of Sir Joseph Banks. Walter Hill, the Colonial Botanist and Director of the Botanic Gardens at Brisbane discovered Doryanthes palmeri in 1860 but it was officially described in 1873 by the British botanist George Bentham. The name honors his countryman and fellow botanist Edward Palmer. Recent treatment places this plant in the Doryanthaceae although formerly it was considered to be in the Agave (Agavaceae) family. There are two species in the genus, Doryanthes palmeri and Doryanthes excelsa. The foliage of the two is similar, though D. palmeri a larger plant and in flower they are easy to tell apart with Doryanthes excelsa having a much taller flower stalk (to over 20 feet tall) that rises vertically out of the center of the plant and topped with a compact capitate head of flowers while the shorter flower stalk on D. palmeri is often angled away from the center of the plant because of the weight of the flowers, which are spread out more along the inflorescence. Both species of Doryanthes generally take at least 10 years to mature and flower from seed.  Information on this page is based on research conducted in our nursery library, from online sources, as well as from observations made of this plant as it grows in our nursery, in the nursery's garden and in other gardens where we have observed it. We also will incorporate comments received from others and welcome getting feedback of any kind from those who have additional information, particularly if this information is contrary to what we have written or includes additional cultural tips would aid others in growing Doryanthes palmeri.
