Aquilegia vulgaris var. stellata 'Black Barlow'

granny's bonnet

Product Image
A popular cultivar among garden designers, this lovely granny’s bonnet has beautiful, fully double, spur-less purple-black flowers in late spring above fern-like green leaves. It looks gorgeous with other black flowers and is equally at home in cottage-garden schemes or among grasses. It thrives best in soil that retains moisture over the summer. It is easy to grow and quite short-lived, but self-seeds freely, though rarely to nuisance level.

How to care for Aquilegia vulgaris var. stellata Black Barlow (Barlow Series):

Lift and divide large clumps in early spring and apply a generous 5-7cm (2-3in) mulch of well-rotted manure or garden compost around the plant. Divided specimens may take some time to establish since they don't like having their roots disturbed. Deadhead to prolong flowering.
