Geum April’s Featured Plants Genus: Geum (Avens) Genus of about 50 perennials, mostly clump-forming with dense clusters of hairy leaves and delicate loose flowers in spring – summer. Many popular cultivars are in fact hybrids. Fully hardy. Did you know? – Best way to propagate geums is via division preferably in autumn (otherwise spring), as seed is unreliable. Geum chiloense Species originating from Island of Chiloe, Chile which enjoys a cold, wet climate. These clump-forming plants have dense hairy leaves with equal leaflets and upward facing flowers in early – mid summer and prefer cool, moist soil. A selection of G. chiloense hybrids are below. Ideal for: Attracting bees and wildlife How to grow Hardiness: Soil: Informal and cottage gardens Woodland gardens Close to streams and ponds Front of border Drainage: Light: Pruning: Propagation: Note: hardy down to – 15 degrees C humus rich, heavy, acidic, alkaline, sandy moisture retentive, well-drained full sun to partial shade not needed division in autumn, or spring divide every 3 years to keep condition, discard weak parts Geum ‘Mrs J Bradshaw’ – charming and carefree upward facing double bright orangered flowers in small sprays over dense green foliage in summer.
