A carpet of the blue alpine squill (Scilla bifolia) is slowly appearing across the garden, to complement the pale yellow of the Lent Lily. Like the latter it self seeds and spreads rapidly. The star shaped blue flowers face upwards over handsome, waxy green leaves and though it relishes a spot in the spring sun, it grows best when also supplied with Summer shade. This makes it an ideal spring ground cover for deciduous shrubs or trees, as well as a great addition in a meadow. It is such a great performer under these conditions that it has been awarded the Award of Garden Merit (AGM) and it is one of my favourite sources of blue in the Spring garden, alongside Scilla siberica, Chionodoxa forbesii and Pulmonaria angustifolia ‘Azurea’.
