Hardy geraniums are a popular perennial thanks to their ease and the wide choice. Some will flower right up until the first frost.
The majority of the border types prefer light shade, whilst the smaller alpine types prefer full sun. If you've a spot where nothing else grows, try a hardy geranium – they're pretty indestructible. Hardy geraniums can cope with any soil type and some, such as Geranium sylvaticum and its cultivars, can cope with very dry conditions.
Hardy geraniums can be great self-seeders and plants will often grow in tiny cracks in paving, only going to prove how tough they are.
Hardy geraniums are often bought potted but they can also be purchased online as bare-root plants. If buying bare-root, plant as soon as plants arrive. There is no need to improve soil unless it’s very poor.
Simply plant and water in well, then leave them be.
There are very few, if any, problems that cause concern. Hardy geraniums are trouble-free. However, some can be invasive. Lift and pot up seedlings – they will make great plants for charity sales or as gifts for friends.
There is seldom a need to propagate geraniums as seedlings are easily lifted and potted up from the garden. Plants can be lifted and divided in spring. Growing from seed can be tricky and long-winded.
Hardy geraniums need very little care. They’re not targeted by rabbits, and slugs and snails will eat other plants in preference. They can be cut back right to the ground after their first flush of flowers and will produce fresh foliage and more flowers in the same summer.
Some offer attractive autumn foliage, so resist cutting back too quickly.
