Description EDIT
Slender-stemmed, tuberous perennial up to 60cm tall with radical grass-like leaves, that are dry at flowering.
In January to March, sweetly scented flowers with bright blue to violet-purple sepals, petals that are mauve-purple and green, and a purple-violet streaked lip.
Growing EDIT
Distribution EDIT
Disa graminifolia is found growing on the dry mountain slopes of Cape Province South Africa at elevations of 300 to 1000 meters.
It often grows in fynbos, usually in full sun on densely vegetated slopes.
History EDIT
Graminifolia means 'grass-like' refering to the grass-like leaves.
Uses EDIT
Ecology EDIT
The main pollinator of the blue disa is the carpenter bee, an insect apparently not strong on flower species identification! The plant mimics other nectar bearing blue flowering species of its distribution area and benefits from the pollinator’s mistaken expectation of finding nectar in these flowers.
