Tender aromatic perennial, camphor scented and with a bushy habit, larger growing than most basils. Purple young leaves that become more green as they age but retain the purple veining. Spikes of small lavender mauve flowers.
Best in fertile, well drained soil and a warm sunny position. Drought tolerant once well established. More cold hardy than most basils but will not survive winter frosts.
Pinch out tips to restrict size and promote bushy growth.
Can be used as a culinary herb, though not as strongly flavoured and fragrant as annual types.
Decorative plant, suitable for containers, very attractive to insects.
A hybrid of Ocimum kilimandscharicum x Oimum basilicum 'Dark Opal', found in Ohio, USA.
