James H. Schutte

Family

Boraginaceae

Botanical Name

HELIOTROPIUM arborescens 'Marine'

Plant Common Name

Blue Heliotrope, Marine Heliotrope

General Description

This compact heliotrope yields very large clusters of tiny violet-blue flowers all summer. The robust ‘Marine’ blooms best where summers are cool and has a pleasant fragrance. Garden heliotrope is a tender garden flower that originates from Peru. It is commonly grown as a bedding annual but is a shrubby evergreen perennial where hardy.

The bushy plants are covered with attractive deep green leaves. When conditions are favorable it produces big rounded clusters of many tiny tubular violet-blue flowers. These have a sweet fragrance. In fact, a very old common name for this plant is "cherry pie" due to its sweet fruity smelling flowers which are irresistible to butterflies and bees.

Heliotrope prefers full to partial sun and evenly moist, but well-drained, fertile soil. Regular deadheading will keep flowers coming in profusion as will regular fertilizer. Plant this favorite bedding plant anywhere where cool bright color is desired.
