PLEASE NOTE: Since plants are often sourced from the garden to order, sizes do vary a little, depending on how they come out of the ground, but I always endeavour to give a little more rather than less! They are sometimes shipped bare-rooted, but will approximate the size specified (e.g. a 9cm pot).
|The steely blue flowers of this attractive plant, which appear on wiry stems with spiny leaves from July, are much loved by bees, hoverflies and butterflies.|
|Sowing and/or growing instructions|
|Direct sow in autumn, in a sunny position, thinning to about 18in apart. Alternatively, sow shallowly, covering with a little vermiculite or fine compost, in winter in a cold frame or unheated greenhouse, but plant out in final positions when quite young as this is a tap-rooted plant that resents disturbance when more mature. This plant prefers light, well-drained soil, but benefits from adequate moisture.|
