Species pelargonium

Received my order of mixed Species Pelargonium today, was going to sow them in a tray of vermiculite, but have decided to wait a bit before doing that, as when heading for the greenhouse I got battered by hail, I know things should be OK with using either the hot bed or propagator but as we are still getting frost here everything could be lost if there is a power cut, so will hold fire till its a bit warmer.
