Licorice plant: Helichrysum petiolare

Licorice plant is grown for its wooly, silvery, trailing foliage. Adding vivid color to hanging baskets and containers, its trailing habit also makes it well-suited for low-growing borders or beds. While most licorice plants are silver, one cultivar, 'Limelight', produces chartreuse leaves.

did you know?

This plant's botanical name is derived from the Greek the sun, and golden, and the Latin word because it has conspicous petioles (the slender stems that support its foliage). Its common name comes from the fact that the oils in the leaves have a faint scent of licorice when crushed.

general maintenance:

Remove flowers as they appear to promote growth of foliage. In Zones 9 and colder, remove plants after frost.

pests/diseases:

Caterpillars may eat foliage. Powdery mildew and rust may occur.

controls:

Handpick caterpillars or apply Bt, following label directions. To discourage powdery mildew and rust, avoid wetting leaves when watering and thin stems to increase air circulation. Remove and destroy severely infected stems.

how to sow/plant:

In spring, choose a sunny, well-drained site and place plants in the soil at the same depth they were in containers. Space 12 inches apart. Water after planting, and mulch to conserve moisture.

water and fertilize:

Maintain soil moisture all season, but allow soil to dry slightly between waterings. Apply a balanced all-purpose fertilizer biweekly, following label directions.

garden hint:

Sometimes a garden can be most effective when it focuses on just one color. Try growing licorice plant with a variety of annuals and perennials with silver foliage such as wormwood plectranthus, santolina, Russian sage and English lavender
