These bulbs are only available by pre-order. Pre-order by the end of June for delivery in October / November.
 
Crocuses look brilliant planted in a lawn, at the front of a border, or in pots. They provide valuable nectar for early-emerging pollinators, particularly bees, in February and March.
I don't propagate crocuses bulbs myself. I buy them in wholesale and pass the saving on to you.
