One of our wedding presents was some named rose seeds so with some trepidation we followed the instructions and planted them, and crossed our fingers some would come up. We had six seeds and the instructions were to plant them in a tray of vermiculite and keep moist and between 20 and 23°C (how do you manage to keep the temperature that exact during a British summer?!).
Vermiculite looks worryingly like cat litter! Nothing much happened indoors so we decided to give up on the temperature thing and moved it outside, keeping our fingers crossed again that no local cats would decide to investigate the new toilet facilities. Lo and behold, a seedling emerged within a few days!
cold frame for my cuttings to go in and to help things acclimatize to outside temperatures - bought in the Lakeland sale.
