The Proteaceae plant family is a symbol of the fynbos biome. Many fynbos Proteaceae are serotinous: over time plants grow, flower and store seeds in woody cones, often
for many years.
Young plants grow, mature and flowerSprouters (or 'resprouters') often survive fire
and produce coppice shoots from an underground, woody rootstock
Many seedlings emerge several months after
fire
