Heliotrope

An old-fashioned, hardy annual that has seen a resurgence in popularity, the heliotrope often is found by scent rather than by sight.

Gardeners can’t seem to agree on its sweet scent; some think it  smells like vanilla, others claim it smells like baby powder, grapes, or cherry pie.

Spider Flower

Spider flower plants create striking focal points at the back of a garden due to their ability to grow 3 to 5 feet tall. Nor do they need to be staked to stay upright. In fact, one small plant can grow to create a small shrublike specimen covered in flowers. (Unfortunately, many gardeners overlook spider flower in garden centers because of its weedy appearance when young.) This plant’s spidery-looking flowers add tropical flair to mixed borders. Hummingbirds and pollinators such as butterflies and moths love spider flower for its copious amounts of nectar. Studies show this plant also attracts beneficial insects that feed on pests.
