Common Names for Garden Heliotropes
The garden heliotrope is an old-fashioned favorite that's making a comeback. A plant of the borage family, the heliotrope grows as either an annual or perennial depending on your climate. It's known for its sweet fragrance and long-lasting flowers --- in fact, with care it can flower throughout the summer and into early fall. The most common colors are white and purple. It goes by at least two common names.

Cherry Pie Plant
-
The heliotrope gets this name from the heavy fragrance of its flowers. To some they smell of vanilla or cloves, to others the sticky sweetness of a pie. It's a restful, satisfying scent. This name is most often applied to the older varieties, with deep purple blossoms and crinkled green leaves.
Turnsole
-
This name refers to another common feature of the heliotrope---its leaves and flowers tend to follow the sun each day, bending towards it in a noticeable manner as it travels across the sky. This is also the meaning of "helio" in heliotrope, of course, referring to the plant's affinity for sunlight.

Varieties
-
Now that this Victorian favorite is returning to our gardens, breeders are producing more and more cultivars. Look for Marine, which is dark purple and has a bushy habit. Alba is a white variety, while Black Beauty is named for dark-colored leaves. Early Violet, as its name suggests, is an early flowering variety.
Valerian
-
You will sometimes find an entirely different plant referred to as garden heliotrope. This is valerian or Valeriana officinalis, a pink- or white-flowering perennial. It's often grown in butterfly gardens because it attracts pollinating insects, but it can be invasive. It has a passing resemblance to Heliotropium arborescens in the shape of its flowers and its herbaceous foliage, but it usually grows much taller. It is also adaptable and will self-sow easily.
