Potentilla Cuttings

Taken from a bush in the garden, potted into multipurpose compost and covered with a clear poly bag for 4 weeks. New growth so I assume they have rooted.

All very well but where is there space in my garden to put the resulting new bushes next year???!! I think I've been watching too much Gardeners' World and Beechgrove Garden

Erm, does anyone want a potentilla?
