This attractive annual with vibrant yellow flowers, is an extremely beneficial, indeed often essential plant for the wild flower meadow. With the upper lip having two white or purple teeth, it provides summer colour, and also papery seed pods that rattle when the seed is ripe, and in olden days this was said to show that the meadow was ready to be cut, hence its other common name of "hay rattle".
For best results, seeds are sown directly into the ground where required in the spring. Alternatively, sow in late winter/early spring in gentle warmth, 15-20 degrees C. Prick out into small 3 inch or 7 cm. pots and plant in final position when the plants are established.
