Aquilegia vulgaris ‘William Guiness’
Flowering in early summer, aquilegias fill the seasonal gap between the last of the spring bulbs and the main flush of summer perennials. Aquilegia vulgaris ‘William Guinness’ produces white petals and purple sepals. It’s a much-loved granny bonnet and makes an attractive and long-lasting cut flower. Grow in fertile, moist but well-drained soil in sun to partial shade. Lift and divide clumps every three to five years and mulch annually with well-rotted manure or compost. Aquilegias are prone to self-seeding around the garden.
