Plant of the Week
Latin: Streptocarpella saxorum
When the group of nursery, greenhouse and University professionals got
together to select the Arkansas Select plants for 2002, there was unanimous
agreement that everyone liked the plant but hated the name. Streptocarpella
saxorum does not have a common name, but don’t let a tongue-twisting
dissuade you from trying this interesting relative of the African violet.
Pronounce it Strep - toe - car - pella.
Streptocarpella is a small, tender basket plant from southern Africa that
quickly grows to eight inches tall with a spread of 12 inches across. It
branches freely and produces soft, velvety green leaves that are about two
From nodes along the stem the plant produces an array of slender, almost
wiry, four inch long scapes which terminate in three to five flowers which
gracefully float above the foliage. The flowers are an inch long with a narrow
tube which splays out at the end into a slanted, pansy-like face with five
lobes. The most common color is purple, but various shades of lighter blue are
Some references list Streptocarpella as a selection of Streptocarpus,
but these two groups of plants are considerably different. While the flowers of
Streptocarpus and Streptocarpella are similar, the plant habit is considerably
different. Streptocarpus grows in a basal whorl of leaves with no above-ground
branching while Streptocarpella has a well branched top.
The translation of the Latin name means "Streptocarpus like". The name
Streptocarpus means "twisted fruit", a reference to the slender, twisted seed
capsule that the plants produce. Streptocarpella produces a twisted seed pod but
it is only about an inch long, not eight or more
inches long as seen in Streptocarpus. The epitaph "saxorum"
indicates that in the wild the plant grows amongst the rocks, most likely
suspended from crevices in a rock cliff.
The Arkansas Select program is an effort by the Arkansas Green Industry
Association and University of Arkansas horticulturists to introduce Arkansas
gardeners to new and well adapted plants for their garden. This year the program
has highlighted five plants for the program. For a complete list of the plants
designated as Arkansas Select winners since the program began in 1998, visit the

Members of the African violet family often have a finicky reputation, but
this plant didn’t get the message. It is the easiest to grow of any gesneriad I
have thus far attempted. Most members of the African violet family succumb in
our greenhouse in the winter to the cold water, but this plant tolerates even
this insult to its tropical nature. Our plants have shown some of the yellow
spotting associated with cold water damage, but they tolerate the insult without
Streptocarpella should be grown in a well drained, organic potting mix in
either a hanging basket, window box or decorative container. While not a heavy
feeder, it should be fertilized periodically to keep it growing and flowering.
It is best situated in a bright location where it gets good light but not direct
sun. Like all gesneriads it should have uniformly moist conditions.
This plant not only will perform well on the patio or porch during the summer
months, it will continue to bloom all winter long as a houseplant. In the winter
give it an east or south window to assure it gets enough light to continue
blooming. It is easy to propagate by terminal cuttings.
