Gasteria armstrongii (Flat-leaf Gasteria) A stemless succulent to 2 inches tall with opposite distichous pairs of thick succulent dark green strap-shaped 2 inch long leaves that have acute leaf tips. The leaf surface is rough to the touch with irregular tuberculate transverse bands and in cultivation the leaves rise just above horizontal, but in habitat are generally flat to the ground. Young plants remain solitary but eventually will pup out to form small clusters. In late spring and early summer appear the unbranched flower stalks to 12 to 20 inches bearing nearly inch long pendulous reddish-pink flowers. Plant in a well drained soil in part sun to bright shade in a well drained soil. Can be grown in the ground if away from other more larger more aggressive plants, but also makes a nice potted specimen. This plant grows in the wild on the Renosterveld flats between Jeffreys Bay and the Gamtoos River of the Eastern Cape Province where it is almost embedded in the ground and often hidden among rocks and grasses. The name for the genus comes from the Greek word 'gaster' meaning "stomach", in reference to the swollen shape of the base of the flower and the specific epithet was a name the botanist Selmar Schönland, the director of the Albany Museum in Grahamstown, gave the plant in 1912 to honor William Armstrong, a plant enthusiast from Port Elizabeth, South Africa. It was reduced Gasteria nitida variety armstrongii by Ernst van Jaarsveld in 1992 but elevated back to the specific level in 2005 based on DNA analysis conducted by Ben Zonneveld and Ernst van Jaarsveld. Gasteria nitida is a bigger plant with smooth leaves that, while distichous like G. armstrongii when young, becomes rosulate with age. The individual flowers of the two species are similar, but G. nitida has a branching inflorescence while B. armstrongii is solitary. Brian Kemble notes that it is almost like Gasteria armstrongii were a form of G. nitida that never grew up. Our stock plants from plants originally received from Stockton, California succulent grower Alice Waidhofer. 

Information about Gasteria armstrongii displayed on this page is based on our research about it conducted in our library and gathered from reliable online sources. We include observations made of this plant as it grows in our nursery gardens and in other gardens that we have visited, as well as how the crops have performed in containers in our own nursery field. We will also incorporate comments that we receive from others about this plant when we feel it adds information and particularly welcome hearing from anyone who has any additional cultural recommendations that would aid others in growing it.
