My special candelabra primula is still flowering, getting taller and taller, soon it will run out of buds to open. I thought to start with that it was going to be sterile, but now the seedpods are swelling and hardening so I will be able to sow them and see what turns up. I know they wont be the same, I will have to split is to make more the same, but you never know, something interesting might turn up.
