Fragrant Fields in My Own Backyard – Lavender Dreams Come True!
I’ve always adored the soothing scent of English lavender wafting through Provençal fields on travel shows, but I never imagined I could grow that same premium magic right here in my Zone 7b garden. These Premium English Lavender Seeds (Lavandula angustifolia) delivered exactly that fantasy—and then some. Germination was a breeze: • 85%+ sprout rate within 10 days using the included peat pellet starter kit (a thoughtful bonus!). • Clear, step-by-step instructions walked even this novice seed-starter through cold stratification and ideal soil temps. • Transplanted seedlings at 6 weeks; every single one took root like a champ. Growth & fragrance? Unreal. • By midsummer, my 4x6 ft bed exploded into a purple haze of classic true lavender spikes—denser and more vibrant than anything at the local nursery. • The aroma is pure therapy: sweet, herbaceous, and powerfully calming. I brush past the plants just to inhale that premium, spa-grade scent. • Bees and butterflies threw a non-stop garden party; my pollinator count tripled. Harvest perks: • First-year blooms yielded enough to fill 12 sachets, 3 batches of lavender-lemon shortbread, and a giant jar of homemade bath salts. • Stems dry beautifully—color and scent hold for months. Hardy, deer-resistant, drought-tolerant once established, and certified non-GMO/organic. If you want that iconic English countryside vibe (minus the jet lag), these seeds are gold. My only regret? Not planting two packets. Time to expand the lavender empire! 🌿💜

Easy to plant, flower fast, very beautiful.
Easiest flower seeds to plant due to about pea size. Up fast with showy round leaves and bright colors of beautiful flowers.

Fantastic seeds!
These seeds are awesome. They germinate fast and grow tall quickly. I wasn't sure how well they'd do in my yard since I had to put them in a spot with just indirect sun, but they have grown up to 6 feet tall in about four months and are just starting to bloom. I imagine they would probably grow faster and taller with the benefit of direct sunlight. Super easy to plant and just leave to do their thing.

Updated, Seller is great
Update: Seller reached out to me and offered to send a replacement and provided advice. The seeds need to go through stratification. So if they are not planted during cold weather. Place the seeds in plastic bag with paper towel to simulate the cold before planting, This will help the seeds to germinate. Old Review: Perhaps you need to do a seed sprout indoors before planting. These seeds never germinated. They were fertilized and we had a ton of rain. Nothing grew.

Small Seed Pack
The product description made me think I am getting a much larger package than I got, it's just a regular small seed pack. It strikes me as deceptive.

Bug chaser
I use a lot of marigolds to keep away the bugs. These sprouted so easily and I love them.

انقع البذور في مويه لمدة يوم ثم ازرع بالتربه مباشرة 👍🏻

Sowed the seeds in the middle of June so maybe they'll show up next year. The only thing that has sprung up 2 months later are about a dozen 8" high small white flowers. We've successfully planted many wildflowers over the years so we're hoping the late sowing is the answer. I'll update this in October.
