Vernonia galpinii usually occurs in colonies on rocky outcrops in the Grasslands. It sprouts annually from a woody rootstock and grows up to 60cm. The stemless, lanceolate leaves are hairy. Flowering season is very long, starting in August and lasts until autumn. One stem usually bears only one purple inflorescence.
The flowerheads of Vernonia galpinii are very conspicuous amongst grasses and blends well in a Grassland type planting.
