If you’ve ever tried growing Proteas, Leucospermums, Banksias, or Grevilleas in your garden, you’ve probably learned quickly—they don’t play by the same rules as roses or citrus.

It sounds fancy, but really it’s just planting them on a mound instead of flat on the ground. And it makes all the difference. Understanding Their Natural Habitat In their native homes
