Helichrysum Licorice Plant (also called Trailing Dusty Miller) is a vigorous plant that has white fuzzy leaves on fast growing, slightly upright vines. It is drought- and heat-tolerant and easy to maintain. The Licorice Plant's cascading foliage makes it a nice choice for an edge plant in combination baskets. Its unique foliage also lends itself to be grown alone in 4 inch or 10 inch pots. Helichrysum make a great choice for garden centers looking for diversity for their customers.
Your unrooted cuttings will arrive freshly cut. You will need to plant them immediately
and begin a misting cycle to root the cuttings. This will leech the soil of nutrients, so during the propagation phase use a constant feed of 1/3 the normal recommended dosage
of fertilizer until well rooted.
For best results with Helichrysum, use a constant feed program of 200 ppm N
. A pH between 5.8 and 6.2
is important for the healthiest plant color.
Licorice Plants need to be pinched
, to encourage proper foliage density and pot shape. Pinch 5-10 days after transplanting
to your final container (once the plant is well established), then as needed.
Space pots as needed for proper airflow and light penetration between foliage
. This will vary based on pot size size, but normal 2' centered spacing is usually adequate.
HeightControlPlant growth regulators are not necessary
for Helichrysum. Allow the plant to grow, and shape the pots through proper pinching.
is the number-one pest to watch out for with Helichrysum Licorice Plant.
Helichrysum Licorice Plant is not prone to many diseases, but don't oversaturate the soil
. If the plant sits in moist soil for an extended amount of time, you could end up with root rot or botrytis
. Botrytis grey rot is usually associated with wet or humid conditions. You can prevent botrytis by allowing the plant to dry out between waterings, allowing for good airflow in your greenhouse, and spacing to allow the sun to penetrate to the soil level. The most common chemicals used to treat botrytis and root rot are Medallion and Banrot. Use them as a drench according to each label's instructions.
Planting Helichrysum Licorice Plant Liners
- We recommend planting 5 starter plants per 10 inch basket. Use a well-drained soil in your baskets and plant your starter plants deep, allowing the ellepot to be completely covered by the soil. If you are planting 4" pots, 1 plant per pot should be sufficient. Plant it directly in the middle of your pot.
- Pinching is recommended 5-10 days after transplantation. A second pinch may be necessary depending on the size and shape of the final pot.
Cuttings vary in size between different plant families, but most can be described as tip cuttings (ivy are leaf-and-eye stem cuttings not tips) that stick nicely
in small plug trays such as the 105-plug tray we use (some varieties are better suited for a 50 cell tray, i.e. Angelwing Begonia, Bougainvillea, Setcrecea, etc.). Please do not order unrooted cuttings unless you are an experienced propagator with mist systems and proper temperature control.
