Too late to plant?
I've gone and done something rash. Despite telling myself I should wait until spring, I ordered the following plants, to be delivered in the next day or two:
Pachysandra procumbens (the non-invasive, non evergreen one)
Epimedium x youngianum 'Niveum'
Helleborus x hybridus 'Red Racer'
Sedum kamtschaticum 'Variegatum' (described as semi-evergreen)
I'm in Chicagoland (zone 5B), and we've had unusually cold weather. 15 degrees below average. Temps have been a bit below freezing at night for a few days now. That will continue until Friday.
So my question is, is there anything of the above that I should hold off on planting until Friday? Or anything from the above that I should keep indoors to plant in spring?
Thanks for your help,
