Hi Sheila if your gravel bed is flat you could have problems as they really don't like water sitting in the crown. We plant sideways on in crevasses between rocks.

that's what I do too Mg on its side.

Many thanks Mg and Sbg . . . more or less what I thought. It will go between some largish stones half under a Libertia at 45 degrees, so hopefully that will work.

Good luck Sheila

Thanks! If it flowers, I will put up a photo for you . . .
