How to take Penstemon cuttings
Hi everyone, i bought a bunch of penstemons in a 'deal' in a magazine. They were very tiny when they arrived but i planted them on in pots and they have grown well this summer, but have not flowered. Could I take cuttings from them now, if so how do I do this? I would like to propagate some to sell at our local horti club show next year to help them raise funds ????
