The Protea flower in this picture was grown in upcountry Maui Hawaii. Protea is both the botanical name and the English common name of a genus of South African flowering plants, sometimes also called sugarbushes (Afrikaans: suikerbos).
protea arrangement, in my not so humble opinion protea should not be arranged in bunches. The flower is majestic enough that one is enough, with a little foliage. This detracts from their beauty, the colours are gorgeous.
Protea pudens x longifolia Delicate pink flowers produced in abundance make this lovely shrub glow in winter. Suitable for cut flowers, it can be grown in pots and containers (with Australian native potting mix)
