Botanical Name: Orobanche tuberosa
Species: O. bulbosa
Common Name: Ground Cone
Habitat:Orobanche tuberosa is native to Western N. America – British Columbia to N. California. It is parasitic on Gaultheria shallon, on or near the coast.
Orobanche tuberosa is a perennial plant growing to 0.1 m (0ft 5in).
It arises from a thick root and a bulbous, twisted, scaly stem base, and grows erect to a maximum height near 30 centimetres (12 in). As a parasite taking its nutrients from a host plant, it lacks leaves and chlorophyll. It is dark purple to nearly black in color, with tiny whitish bumps bearing hairs. The inflorescence is a dense spike-like or pyramid-shaped cluster of generally over 20 flowers. Each flower is tubular, between 1 and 2 centimetres (0.4 and 0.8 in) long, and yellow to purple in color.
The fruit is a capsule containing minute seeds.
The species is hermaphrodite (has both male and female organs).
Suitable for: light (sandy), medium (loamy) and heavy (clay) soils and prefers well-drained soil. Suitable pH: acid, neutral and basic (alkaline) soils. It can grow in full shade (deep woodland) semi-shade (light woodland) or no shade. It prefers moist soil.
Considering its native range it should succeed outdoors in most parts of the country. It requires a well-drained soil and should succeed in sun or shade. A fully parasitic plant lacking in chlorophyll, it is entirely dependant upon its host plant for obtaining nutrient. According to , the correct name for this species is Boschniakia hookeri.
Roots are edible. The potato-like stem bases were occasionally peeled and eaten raw as a snack by some North American Indian tribe.
The roots have been used in the treatment of coughs.
