( they’re clumps of recently flowered  &   lifted bulbs sold in brown paper bags. Prices from 10 bulbs for £5  We also sell Winter Aconites the same way. If you’ve tried growing from dry bulbs without success this is the way to succeed with flowers still visible they have the potential to also self seed for next year. & double the plants for you.
