Brassica oleracea convar. acephala. Grow all the year round as a 'baby leaf' indoors on the windowsill. Outdoors if given wider spacing it will make an abundance of densely curled leaves over a very long period. Winter hardy as a full sized plant.
Sow seeds from March to May outside, or sow and eat all year round as a 'babyleaf' indoors. Sow seeds thinly direct outside or in containers, 13mm (½in) deep.
Thin as necessary or transplant to 20cm (8in) apart for mid sized leaves or to 37cm (14½in) for larger plants.
Keep well watered during dry weather. Can also be sown regularly in pots of seed sowing mix on the windowsill for a continuous supply of 'baby leaves'. If a few plants are missed and not picked as salad leaves, these can be planted into large containers and left to mature as large kale plants for winter use.
Use raw in salads or as a steamed vegetable.
