— Astrantia are full hardy and can be planted straight outside in the spring.
— Either plant the roots directly into a clear, prepared space in the border in spring or pot them up into temporary pots to grow on and plant out as potted plants later.
— Soak the roots in water for 3-6 hours prior to planting.
— Choose a part of the garden with free draining soil which is in full sun, partial shade or shade.
— Plant the roots so that they are fully submerged with the buds or crown just below the surface and with any top growth exposed.
— Space the plants 15-20cm apart
— Water-in after planting and keep hydrated when in growth in the first year.
— Cut stems down to 3cm above soil level in autumn.
