Ononis natrix is a moderately cold-hardy plant, able to tolerate temperatures down to around -15Â°c when fully dormant[
Requires a sunny position, growing best in a well-drained, neutral to alkaline soil[
]. Succeeds in shallow chalk soils[
The plant is particularly useful for growing on the tops of walls or on dry banks[
Plants are resentful of root disturbance and should be moved with care[

Scarify or pre-soak the seed for 24 hours in warm water and sow the seed in early spring in a greenhouse[
]. The seed can also be sown in a cold frame in the autumn. Plants resent root disturbance and so, as soon as they are large enough to handle, they should be pricked out into individual pots and then planted out in late spring[
