If first growing indoors, then sow Geum seeds about 10 weeks in advance.

It should take three to four weeks for Avens to germinate at 18 to 21 degrees centigrade (64 to 68°F).

Once ready, transplant plants into the garden at the start of spring or autumn. Ideally use a spacing of 30 to 45 cm (12 to 18 inches).

Geum plants, such as Purple and Mountain Avens, are easy to grow and look after. It is a good idea to remove dead flowers to prolong blooming and to help keep them tidy.

If you require more plants then propagate by division in the autumn.
