Guide to growing Avens (Geum)
Geum are hardy perennials that range from 15 to 90cm in height.
They bloom in the summer when they carry circular red, white, purple or yellow flowers.
Commonly grown Geum in the garden are Mountain Avens, Wood Avens, White, yellow and purple Avens, and Alpine Avens.
Some of the common latin name of Geum species include geum triflorum, geum chiloense, geum borisii and geum aleppicum.
How to grow Avens
If growing Avens and other Geum species from seed, then sow outdoors at either the start of spring or autumn; lightly cover the Geum seeds once sown. Avens likes to grow in sunny areas of the garden that has good drainage; they can tolerate partial shade in hot climates. Ideally the soil that the plant grows in will be rich and slightly acidic to neutral pH (5.5 to 7).
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. Once ready transplant Geum species into the garden at the start of spring or autumn with a spacing of 30 to 45cm.
Caring for Geum
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 keep them tidy. Supply a mulch in winter. When the plants begin to look tired (about 4 years) divide them to maintain vigour. If you require more plants then propagate Geum by division in the autumn.
