Plant Out Or Not

Question

Fathers Day present. Wildflower seeds. Sowed in a container. Planted into pots. All a bit late. Now have some fine robust perennials in 8inch pots. Plant in garden now or wait til Spring. If wait, keep in cold greenhouse or in house.

Answer 1

It depends on the exact flowers in question, but keeping them indoors under lighting will help you get a head start for the Spring.

If you have no such space indoors, then a greenhouse can be fine.
