Oyster Leaf Plant - SeedsMertensia maritimaSea bluebells

Seeds require cold stratification at temperatures below 2°C for germination to occur. Sow into gritty, free-draining compost in small pots and keep in a shady cold frame throughout the winter to expose the seeds to a long spell of cold weather. When seedlings are large enough to handle, pot up into 15cm pots being careful not to disturb the plant's roots. Grow on in a sunny/shaded spot with protection from the midday sun in light, free draining soil. Provide protection from slugs and snails as soon as seeds germinate.
