Autumn sown perennials

| I've just planted out the Salvia patens I sowed last year, one of which is showing flower buds. I sowed the seeds last September collected from a single plant which had set good seed. It germinated immediately and I overwintered the seedlings in an unheated propagating frame in the greenhouse. I don't think they got frozen, but the temperature was always low and they remained dormant until late winter. I've potted them on into 1.5 litre pots now that they're in vigorous growth, and they're already forming tubers. I'm amazed at how easy and prolific they have been to propagate using this method. I would be interested to see how these progress now they have been planted out, and what colour they will be (the stock plant is Cambridge Blue). Has anyone else been successful raising perennials from autumn-sown seeds? It seems to be a method with a lot of merit. |

| I tend to take the view that if Nature produces the seed in Autumn (or July, for that matter)it is probably OK to sow it. I follow this rule whenever I can, and the results are invariably acceptable. Most young plants are in individual pots by September (size depending on species), and stay there until they show new growth in the Spring. Chris |

| I do it all the time. Winters here are mild enough that even the smallest seedlings will come through it ready to take off in spring. |

| So do I. I've grown most of my hollyhocks, delphiniums, penstemons, Aquilegias, Astilbes and Clematis from autumn sowing. |
