Botanical Name:

Salvia Black Knight is a large salvia, growing to 2 meters high and 1 meter wide. The flowers begin as almost black and fade to deep purple as they age. The flowering period lasts from early summer to autumn. The mid green leaves are aromatic.

Growing Conditions

Black Knight prefers to grow in a warm sunny aspect and can take being dry between watering periods. Alternatively it can tolerate being constantly moist. Most soil types are tolerated well, so it is quite versatile. However, this salvia may be prone to frost damage and it can be useful to prune the stems in winter and protect the roots with pea straw. Black Knight is known to be deciduous in colder areas of the world, but the plant will return in spring. Since it is a large growing salvia it is often best suited to the back border or as a fence screen.

The salvia family has over 900 members with an extensive history as culinary, medicinal and ornamental plants. Ornamental salvias have become collectorsí items, as gardeners try to find a place in their garden for each and every one. There are salvias that will suit every type of soil and climate. More information on the Salvia genus and Common Sage (Salvia officinalis) may be found on our Common Sage page.

    Great product with fantastic service

    Our herbs arrived in very good condition in very quick time. They have taken off, doubling in size within a couple of weeks in the garden. Mudbrick Cottage and their team communicated so well with us and they have the best service.
