In the garden
Geranium (Cinereum Group) 'Janette' is a cultivar in the Geraniaceae valued for its mat-forming habit and long flowering run. As a member of the Cinereum Group it presents spreading, trailing stems that knit together to form low clumps and mats rather than an upright mound. The plant is suited to temperate UK gardens and is used where a ground cover that flowers through summer is required. Plant 'Janette' in a sheltered position with either full sun or partial shade. It tolerates a wide range of soils — chalk, clay, loam or sand — provided the soil is well drained; avoid sites that remain waterlogged. Soil pH may be acid, neutral or alkaline, so there is no special need for pH adjustment beyond ensuring good drainage. The cultivar is suitable for UK hardiness ratings H5–H7 (hardy to fully hardy), so it will withstand typical British winters when given shelter from severe exposure. Use 'Janette' in flower borders and beds, as ground cover on banks and slopes, or underplanting roses and shrubs where its trailing stems can fill gaps. It also fits cottage and informal schemes and wildlife gardens. Expect an extended display from June to September, making it a practical choice for stretching the summer colour beneath taller plants.
