Prunella vulgaris Rose Pearl

American Heal-all

A compact plant that flowers for a long period at the end of the summer

Rose Pearl' is a compact, spreading herb with mid-green leaves and beautiful two-lipped purple-pink flowers on short spikes. A lovely little plant that which is in bloom over a long time, from early summer to autumn. Bees love it as well.


Happy in full sun or part shade. Delightful in a container, and also as ground cover or use in a bed, border edge, or bank.


Loves a rich, moist, free-draining soil. Enrich the soil with organic matter before planting - home made garden compost or well rotted manure is fine. Use good quality loam based compost for container growing and raise the pot on 'pot feet' through the winter months to help with drainage.

Planting instructions

Water the plant in its pot thoroughly before planting – give it a good soaking. Prepare the area by digging a hole twice the size of the pot. Dig compost into the base of the hole. Remove the pot and position the plant in the hole, with the top of the rootball about level with the surrounding soil. Refill the planting hole with a mixture of garden soil and compost, firming as you go. Water in well and keep well watered during the plant's first year.
