Pediomelum subacauleAlso known as:
The overall appearance of Pediomelum subacaule is reminiscent of that of lupine, but shorter, with hairier stems, and terminal flowers forming a compact cluster rather than an elongated spike. The total height of the plant will rarely exceed 12", including the flowering stem. A spring bloomer with vivid, deep shades of blue to violet. All above-ground parts of the plant will die back by mid-summer.
Pediomelum subacaule is a rare, endemic species, found only in a handful of counties in the southern Appalachians known as "cedar glades". It is found in rocky limestone soils, and requires a well-drained, moist to dry, cool environment, in full to part sun. Blooms in March or April. Zone 6
Propagate from seed. As with other members of the Pea family, seeds will benefit from an overnight soak before sowing.
The tuberous roots are edible and yam-like. Native Americans would consume them fresh, dry them for winter use, or grind them into flower, hence the common name "Indian breadroot". This is a very rare species and should not be collected in the wild.
