Description

(Lavandula multifida). Butterflies cannot resist this alluring lavender! This stunning aromatic ornamental hails from the Mediterranean and is also known as fern leaf lavender. The beautifully incised foliage is silvery, making the bold purple flower spikes really pop! It blooms summer to frost, and the plants reach 24 inches tall and wide.

Growing Tips: Torch Blue lavender grows best in well-draining, sandy, or gravelly soil. Poor drainage can lead to root rot, especially in winter. Avoid heavy clay and be careful not to overwater the plants. Once established, it is drought tolerant and needs deep but infrequent watering. Prune after flowering and cut back one-third of the plant in late summer to maintain its shape and encourage bushy growth.

When to Grow

Torch Blue lavender is perennial in USDA Zones 7-10 and will return each year. In colder zones, grow it as an annual or in containers that can be brought indoors for winter. Start seeds 8-10 weeks before the last frost and transplant outdoors after all chance of frost has passed. Young plants should be protected from freezing temperatures.

How to Sow and Plant

Sprinkle the seeds on a moist paper towel and hold it in the fridge for 30-40 days before planting. When they sprout, they can be placed into pots and grown indoors until planting outdoors after the last frost date. Surface sow onto well-draining soil and press lightly—do not cover, as seeds need light to germinate. Keep soil moist but not soggy. Once seedlings are 2-3 inches tall, transplant them outdoors in full sun. Space the plants about 12 inches apart. Avoid heavy clay, which can cause root rot.

How to Grow

Young seedlings should be watered regularly, while mature plants prefer deep, infrequent watering. Overwatering can be harmful, especially in humid conditions. Fertilize very lightly, as too much nitrogen can reduce fragrance and flower production. Apply a light compost or a low-nitrogen fertilizer in early spring if necessary. Generally, lavender is pest-free, but ensure good air circulation to prevent fungal diseases.

How to Save Seeds

  • Allow the seedheads to dry on plants and hand pick or cut stems and shake seeds free into a bucket or bag.
  • Separate seeds from chaff by carefully winnowing and store in a cool, dry place.

FAQ

What can I plant with Torch Blue lavender?

Good companion plants include rosemary, thyme, sage, and echinacea, as they all thrive in similar dry, well-draining conditions. Avoid pairing it with plants that need consistently moist soil.

How can I prevent my Torch Blue lavender from becoming too woody?

Prune it after flowering and cut back one-third of the plant in late summer to maintain a compact shape and encourage new growth. Avoid cutting into the woody base, as lavender does not regrow well from old wood.

How long does it take for Torch Blue lavender to bloom?

Unlike English lavender, this fernleaf lavender blooms its first year from seed, generally 90 to 200 days after sowing, and keeps flowering from summer until frost.
