Prunella are mat growing hardy perennials that range from 15 to 30 cm in height.
They bloom from spring through to autumn and carry hooded clusters of small flowers that are usually blue or purple in colour.
Their size makes Prunella great for using in rock gardens, or for growing in a garden border.
The common name for Prunella is Self Heal.
Prunella grandiflora by Nuuuuuuuuuuul.
Sow the seeds of Self Heal and other Prunella members outside at the start of spring before the last frost. The seeds should be lightly coved once sown. Ideally they should grow in a soil of pH 6 to 7.5. Prunella plants can grow in both sunny and partially shaded areas of the garden.
If starting indoors then do so about ten weeks in advance (they should be transplanted outdoors in the spring)/ It should take from one to two months for the seeds to germinate at a temperature of 12 to 18 degrees centigrade. Once ready transplant outdoors with a spacing of about 30 to 45 cm.
It is easy to grow and look after Prunella species in the garden. They require regular dead heading of old flowers to maintain attractiveness and to encourage further blooming. Once the flowering season is over cut the plant back to ground level. It is a good idea to plant in a confined area of the garden such as a rock garden, and to control rigorously as they can easily take over the garden (especially the lawn).
