perennials I didn't get round to planting
In September I bought a collection of perennials, some of which I haven't got around to planting yet. They are anemone hupehensis 'Serenade', Coreopsis verticillata, Clematis 'Cassandra' (a heracleifolia cultivar), Scutellaria incana, Crocosmia 'Buttercup' and Rudbeckia subtomentosa 'Henry Eilers'. There were all potted on after I got them, they're in 3L pots. Will all these be OK just standing outside or do any of them need to be in the cold greenhouse?
