Monty is already thinking about next year which means now is the time for him to start collecting seed. He collects seed from astrantia and silene and stores them in brown paper bags. He bought the silene from the Malvern Show in May which started the planting off and now he can keep it going by growing it from seed. The astrantia will germinate very fast, so Monty will be able to store young plants over winter rather than the seeds, which means he can plant them out a little bit earlier and get mature plants a bit quicker. He therefore plans to sow some now and some next spring. Monty points out that if you're sowing seed from a hybrid like the astrantia called 'White Giant', It could actually be quite different from the parent, and that could be seen as a disaster or an opportunity. But if you really want to replicate the parent plant it's easier to do it with a cutting, particularly if it's a flowering shrub like the lavenders in Monty's garden, so he takes cuttings from lavender, looking for semi-ripe material and not flowering material.
