I certainly understand about the uncertainly of our weather down here during the early spring. My saying is: "If you don't like the weather today, wait until tomorrow. It will be different but not necessarily better".
I buy my bifurcatum as plug plants (have 98 waiting for warmer weather to ship in fact) and have gone completely to the Netherland subv. Those I will mount and sell.
My personal plants include the P. mauno loa, P. Mickey's rainbow, and P. veitchii lemoinei. Just mist your plants every other day, keep them warm, and they'll be fine.
