I love growing things from seed , but have never tried growing dahlias this way . Last October, I was digging up and cleaning up my dahlia bed out at the farm. I wondered if any of the dried, ugly flowerheads had any seeds in them….so I pocketed one . Just one. It was from a big peachy orange cactus type called ‘Wynn’s Sensation’ , possibly my favourite. I remember picking through the chaff ( = dried crap) and thinking the odd bit might be a seed and putting it aside. Those ‘odd bits’ looked like thin, hooked, slightly anorexic sunflower seeds. I found ten of them . This spring I sowed the seeds together in an 8″ pot in my heated greenhouse. I got 8 big seedlings and planted them in a row in the sun…. and look what I got ! Every one of them is fabulous ! I am not a qualified dahlia judge…. but I am keeping them all for sure. Quite a different story than with my hundreds of daylily seedlings. Or my orchids (still waiting to bloom after 11 years) . These dahlias are really nice . They are upright and strong , with very long stems. Needless to say, very soon I am going to scrounge for more dried flowerheads , and grow lots more dahlias from seed !! Go and check your plants right now, and don’t cut off every spent flower.
