Pulmonaria 'Blake's Silver'

A clump-forming to spreading, semi-evergreen herbacious perennial with silver foliage set off with a green rim and green leaf base. In March it is crowded with good trusses of nicely flared and shaped baby-blue and pink flowers which look outwards rather than down. Opening quite a rich pink it quickly softens to a pastel pink, tinged blue at the edges and finally the colour changes completely to a soft blue with a pink throat.
