Green protea

Protea coronata

Green sugarbush (Eng.), Groenhofiesuikerbos (Afr.)

1/2

The Green Protea is an attractive, upright, messy shrub with very attractive and most unusual flower heads. Unlike most proteas it prefers heavy clay soils and fairly high rainfall. It goes unnoticed by many as the flowerhead is so well disguised in the green shrubbery. The flower is much sought-after and is cultivated for the cut flower trade.
