Nodding Pincushion. Leucospermum belongs to the protea family and is indigenous to South Africa. The inflorescences consist of a large number of small flowers. It is the stiff protruding styles of the flowers which are the source of the common name "pincushion" for this genus. Only a few large, hard, nut-like seeds are produced by each inflorescence. In their natural environment the seeds are collected by ants, stored in the soil, and germinate only after a fire has killed the mature plants and returned the nutrients back to the soil.
