Protea Species, Waterlily Sugarbush

I have only recently purchased this plant, so I do not know how well it will fare outside in my Colorado (USDA Zone 5) garden. It is grow...Read Moreing well indoors. Inasmuch as it grows in Lesotho and the Drakensberg Mountains of South Africa, I hope to trial it in this similar high altitude. The plant is available for purchase from The Desert Northwest nursery.

I have not grown this plant or any other protea -- and the naturally high phosphate in the soil here might doom any efforts. But suppose...Read Moredly P. subvestita can tolerate zone 6 cold according to at least one source, the seed is best sown in Spring, and the plant is adapted to wet summers and can tolerate humidity. Definitely on my list of plants to try.
