Protea plants should have well drained soil. Their roots grow mostly horizontally, just below the soil surface. If water is allowed to sit and collect on the surface, the roots will become waterlogged and the plant will rot. Proteas can withstand a range of temperatures from -5 C to 38 C, although they may not survive long exposure beyond this. Flowers come in large clusters surrounded by shiny, spiky filaments that create a very unusual and striking appearance.
