Omphalodes Linifolia
This is a quite spectacular small plant with grey-green leaves, above which arise profuse sprays of faintly sweet-scented, pure white, golden-eyed flowers all summer long. This lovely thing will gently self-seed around the garden.
Sow seeds in early spring in gentle warmth. Pot on into small pots before planting out in late spring. These plants do best when the seed is sown in situ or even just sprinkled around the desired area, as they dislike being transplanted.
