Please donate to support our ‘Plants to Save the Planet’ Project. The Project is directed at enabling designers of ‘carbon farms’ and ‘food forests’: agroecosystems of perennial plants, to choose the most appropriate plants for their requirements and site conditions. We are working on a subset of plants in the PFAF database identified as having the most potential for inclusion in such designs. We are adding search terms and icons to those plants pages, and providing a range of search options aligned to categories of plants and crop yields, with Help facilities including videos. More >>>

Edible Uses

Leaves - raw or cooked[2, 16, 46]. A strong cabbage flavour, they are delicious if used when fairly young though they can become tough with age[K]. The leaves are usually available from autumn to late spring, and can be harvested all through the winter in all but the very coldest of seasons[K]. Young flowering shoots - raw or cooked. Picked before the flowers open, they are fairly tender and can be used as part of a mixed salad. When cooked, they have a delicious flavour similar to sprouting broccoli[K].

Our new book Edible Shrubs is now available.

Edible Shrubs provides detailed information, attractively presented, on over 70 shrub species. They have been selected to provide a mix of different plant sizes and growing conditions. Most provide delicious and nutritious fruit, but many also have edible leaves, seeds, flowers, stems or roots, or they yield edible or useful oil.

Cultivation details

The acephala group refers to any type of Brassica which grows without the central 'head' typical of many varieties of cabbage. These are included within the species Brassica oleracea, such as Kale (Brassica oleracea var. acephala).[1] The name literally means "without a head" in contrast to those varieties known as capitata or "with a head". This group includes a number of species, both wild and cultivated, many of which are grown for their edible leaves and flowers. A very easily grown plant, succeeding in full sun in a well-drained fertile preferably alkaline soil[16, 200]. Prefers a heavy soil[16]. Succeeds in any reasonable soil[37]. Shade tolerant, growing well on a north border[37]. Succeeds in maritime gardens[200]. Tolerates a pH in the range 4.2 to 8.3. A very hardy plant, tolerating temperatures down to about -15°c[200]. It also tolerates high summer temperatures[200]. Often cultivated for its edible leaves, collards are especially useful for providing leaves throughout the winter and spring, it is very cold tolerant. There are several named forms[183, 200] but this vegetable has fallen out of favour somewhat since it is considered be coarser than other vegetables that can be imported from warmer areas in the winter.

Propagation

Seed - sow in a seedbed outdoors in April/May. Plant out into their permanent positions in the summer as space permits. Do not let the seedlings get overcrowded or they will soon become leggy and will not make such good plants. If your seedlings do get leggy, it is possible to plant them rather deeper into the soil - the buried stems will soon form roots and the plant will be better supported. The perennial forms can be increased by cuttings. These can be taken at almost any time that they are available. Use shoots about 8cm long of the current year's growth and place them in individual pots in the cuttings frame. They root very quickly and easily[K].
