Stellaria jamesiana - Torr.

Common Name tuber starwort
Family Caryophyllaceae
USDA hardiness 4-9
Known Hazards Although no mention has been seen for this species, the leaves of some members of this genus contain saponins. Although toxic, these substances are very poorly absorbed by the body and so tend to pass through without causing harm. They are also broken down by thorough cooking. Saponins are found in many plants, including several that are often used for food, such as certain beans. It is advisable not to eat large quantities of food that contain saponins. Saponins are much more toxic to some creatures, such as fish, and hunting tribes have traditionally put large quantities of them in streams, lakes etc in order to stupefy or kill the fish[K]. Stellaria jamesiana Torr. is a synonym of Pseudostellaria jamesiana (Torr.) W.A. Weber & R.L. Hartm.
Habitats Moist woodland amongst shrubs, westwards from Wyoming and Texas[85].
Range Western N. America.

Cultivation details

We have very little information on this species and do not know if it will be hardy outdoors in Britain, though judging by its native range it should succeed outdoors at least in the milder parts of the country. Prefers a moist loamy site[85]. For polyculture design as well as the above-ground architecture (form - tree, shrub etc. and size shown above) information on the habit and root pattern is also useful and given here if available. The plant growth habit is a clumper with limited spread [1-2]. The root pattern is tuberous with swollen potato-like roots [1-2].

A few notes: 1. This species seems to have been moved to Pseudostellaria jamesiana. See http://plants.usda.gov/java/profile?symbol=PSJA2 2. It has a tradition of medicinal use by Navajo as "Poultice of plant applied to hailstone injuries." See http://herb.umd.umich.edu/herb/search.pl?searchstring=Pseudostellaria+jamesiana 3. Jacke & Toensmeier, Edible Forest Gardens volume 1, page 78, describe this as a "shade-tolerant medicinal plant and superfood, its mineral-rich leaves providing healing to all tissues, especially the lungs and skin. Its tasty tubers and lettucelike leaves are also good edibles, while its flowers attract beneficial insects." However, they do not provide a citation for these assertions.
