Description
Fernleaf lavender is a striking perennial variety distinguished by its deeply lobed, silvery-green, fern-like leaves and tall stems crowned with elegant blue-violet trident-shaped blooms. This first-year flowering plant has a bushy, compact habit and produces vibrant blossoms throughout the summer, making it a standout choice for borders, beds, and decorative containers. The foliage emits a delightful aroma with a hint of oregano, attracting butterflies and enhancing any garden with both beauty and fragrance. Easy to grow from seed, Fernleaf lavender thrives in sunny locations with well-draining soil.

Match ‘Fernleaf Lavender’ Butterfly Herb to the light, soil, and temperature information recorded for the species. Some herbs are direct sown, while others benefit from a protected start or species-specific pretreatment, so retain the packet for reference. Keep seed media from drying during establishment without leaving it saturated. Once plants are growing, harvest modestly so foliage remains for continued development. Assign perennial herbs a long-term location, and consider containers for species with a spreading habit.
Its long blooming season and unique foliage texture make it a versatile option for ornamental and pollinator-friendly gardens.

Before sowing ‘Fernleaf Lavender’ Butterfly Herb, review the packet alongside the current product details and note any range in temperature, germination, or maturity.

Planting & Care
Planting & Care
Planting: In early spring, sow lavender seeds 1" apart in a container of seed starting mix. Cover very lightly and keep at 60 - 70°F. Keep evenly moist but not soggy until seedlings slowly emerge over 7 - 14 days, providing a good light source. When seedlings have several sets of leaves, transplant 2" apart into deeper containers. Plant outside in a well-drained sunny spot when plants are 2 - 3" tall after gradually acclimating to outdoor conditions.
Growing: Because perennial lavender's small seeds germinate slowly and unevenly, we strongly recommend starting them indoors so you can tend them carefully. Plants flower lightly the first season and come into full bloom in their second summer. After blooming season, prune and shape the plants while cutting off spent flower stalks. If their requirements are met, these sturdy plants will take more humidity than other lavenders. Fernleaf plants are beacons for summer butterflies all summer long.

I love lavendar and have several varieties so last year thought I'd add another one. At first the scent was a bit off-putting it was not like any other lavendar I have ever smelled. Now this is my all time favorite! Grows extremely well in our hot summers and does overwinter without much care. If you want a great surprise to show your garden group this is the one! Love it so much I bought more seeds this year. Not that I needed to for my garden since it does spread well on its own but as gifts for my gardening friends. It always surprises my other lavendar loving friends! Highly recommend it but be careful it is very addictive!!!
