This January I started growing some perennials from seed - to reduce cost and to fill gaps in the garden. I have grown:
coreopsis
echinacea
rudbekia
verbena bonesaires
china roses
i was expecting 50% success but they’ve all grown and now I have about 40 10cm pots with perennials in which, apart from the roses which have flowered all summer and been on the patio, are still in pots.
i was following the general advice that perennials from seed are still quite ‘small’ first winter and keeping in pots is a good idea so they can be moved/protected. None other than the roses have flowered this year which I expected.
now I seriously don’t need them all, so I’ve donated lots to our local community garden but have said I’ll keep them till spring for them.
should I keep them in the greenhouse? I’m worried I’m going to run out of space! I have other stuff to go in there too in November!
and - will they die back to nothing like other perennials do? Or should I cut them back? Or just leave them alone! They are bushy and verdant at the moment so I’m not sure!
thanks
