The plant prefers acid, neutral and basic (alkaline) soils and can grow in very acid and very alkaline soils.
It can grow in semi-shade (light woodland) or no shade.

Edible Uses
Flowers
Leaves Stem.
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].

Cultivation details
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].
Cultivars
- ''
- There are many named varieties of this annual vegetable, with new forms being developed. At present there is not time to enter these in the database and it is recommended that you consult the book 'The Fruit and Vegetable Finder' which is updated regularly and can be obtained from libraries.
There is one perennial cultivar, which is entered on the next page.

[183] Facciola. S. Cornucopia - A Source Book of Edible Plants. Kampong Publications 1990 ISBN 0-9628087-0-9 Excellent.
