I have not grown this plant which is indigenous to South Africa. Princess Protea, Peach Protea (Protea grandiceps) is slow growing and has a rounded habit. The grey-green, broad leaves have red margins. From spring until late autumn, it produces inflorescent heads which incurve and barely open, but are still attractive. They are flushed a peach pink and tipped with fluffy white hairs. It is not well suited to very dry areas or regions with very severe frost

This plant has been said to grow in the following regions:
