I just bought a bunch of wallflowers, for a quid, from a street
market.

Being my first ever wallflowers - what do I do with them until I can
get them in the ground at the weekend?

Put them in the shed, or will they be OK indoors with the dry central
heating?

Should they be plunged into a bucket of water?

And when I do get them in the ground, do they prefer sunny or shady
places, dry or wet?

Wet newspaper or damp sacking round the roots in a cool place will do.
Or just place roots loosely in some damp compost/sand etc. DO NOT put
them in water.. smells horrible!
