This varied genus of plants is named for the sea-god of ancient Greek mythology, Proteus, who was known for his ability to change his appearance at will. It’s said that the proteaceae family was named after him because of the incredible variety of shapes, sizes and textures it presents itself in.
There are numerous Proteaceae genera however some are more well know than others; Aulax, Banksia, Brunia, Grevillea, Hakea, Leucadendron, Leucospermum, Macadamia, Mimetes, Serruria, Waratah and of course Protea.
The most well know protea is the King Protea which is also the national flower of South Africa.
What makes them all part of the same family despite looking so different, is their root system. These plants have proteiod roots which are a specialised root system which form clusters of closely spaced, short roots. They enhance nutrient uptake and as a result, plants with proteoid roots can grow in soil that is very low in nutrients.
