Hi,
I have mostly perennials that I suppliment with annuals. Usually, I just buy new, but after growing Snapdragons for the first time this year I'd love to save them somehow. I'm growing 'Rocket Red'.

I bought a 6-pack in spring, but didn't get around to planting them for a while. By the time I did, they were pretty sad looking so I cut them back about half way. They're also in part shade since most of my garden is shady. They started blooming in early August and look beautiful. Each day they get more buds.

I've read that the 'Rocket' series get tall and leggy, but these have not (maybe because I had to cut them back when I planted them).

I really love these and would like to grow them again next year.

Is there any way these can be saved for next spring...either cuttings, seeds, root cuttings or even whole plants tucked away in a garage? I've read seeds may not grow true. I live in Zone 5a.

Are they a good candidate for Winter Sowing? It's warmer up near the back of my house since we get full sun there.

Any help would be greatly appreciated. I'm not a newbie gardener, but kind of a newbie at saving plants over winter. I've saved cutings of Coleus and assorted house plants with soft stems and even let some seeds dry on a few perennials and scattered them, but that's all.

Thank You in advance for any help!!
