Tradescantia 'Zwanenburg Blue' is a proven spiderwort with deep violet-blue, three-petalled flowers. Golden-yellow stamens glow at their centre. From June to August new flowers open every day above a sturdy clump of glossy, dark green, narrow leaves.

About this variety

The blue of 'Zwanenburg Blue' is one of the darkest among spiderworts. The three rounded petals look almost velvety, and the golden-yellow anthers form a bright centre. The buds sit in dense clusters at the shoot tips and open one after another, so the plant shows colour all summer long.

At about 45–55 cm tall, it suits the front and middle rows of a border, the banks of ponds and streams and partially shaded areas. Fertile, moist to damp soil is important, ideally loamy or clay. Yellow daylilies, lady's mantle, white astilbes or light green hostas make the deep blue glow. Planted in groups, it is particularly striking.

Bees and bumblebees visit the flowers regularly. It is only of limited use as a cut flower, as each flower lasts just one day. The perennial is very hardy, even at higher altitudes, and grows ever stronger over the years. Cutting back after the main flowering brings fresh foliage and more buds.

Planting

Plant in spring from March to May or in autumn in September and October in a partially shaded or sunny spot with damp soil. Dig a planting hole twice the size of the root ball and set the crown just below the soil. Keep 35–50 cm between plants and water in thoroughly.

Care

Keep the soil evenly moist and water generously in dry spells. Compost in spring provides the necessary nutrients. Cut the shoots back after the first flush and the plant will flower again. Divide the clump every few years. Wear gloves, as the sap can irritate the skin.
