Protea, Leucadendron, Leucospermum and Aulax

I have always loved Proteas and decided since I had the space I would try to grow them.  Some of the shrubs/bushes seem to be going well but some have died off some what so I suppose time will tell at which ones will do alright and which ones wont.  I am hoping to produce enough different varieties to be able to supply to the public but if I don’t then I will have some very pretty flowers for myself to admire.
