Planting Outdoors spring

From Mid Spring TO Late Spring

Plant out in spring in a water retentive soil that is free draining. Lysimachia are ideally suited to pond margins where the soil will retain moisture during dry spells. Plant in full sun although they will still thrive if planted in dappled shade. If planting the low growing varieties for ground cover, plant at 50cm apart.
