Buying 9cm plants now
I've noticed an offer on a website to buy some rudbeckia black eyed susan in 9cm pots.
I'm looking to introduce these into the garden so seems a cost effective way to do it, however how would I need to look after them once I've purchased them ? I don't have a greenhouse or coldframe.
I'm also assuming I'll be buying 'empty' pots as the plants will be hidden under soil still?
also are they likely to flower this year ?
Thank you as ever for your advice. x
