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! 🌿💜

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.

Nice all around
beautiful assortment of seeds. cant wait for spring. it's a great bargain for the price, IF they actually sprout. I won't know for a few more months. Also, it contains maximillian sunflower which are perennial and will not sprout until next summer unless they're planted in autumn.

Good germination
Good germination rate, and maybe I did something wrong but the petals on mine are far more similar to daisies than what's shown on the bag and what I think of for zinnias. Only one layer of petals came in on any of them.

Great value! Beautiful color!
This bag of seeds it’s a great deal and they are heirloom non-GMO. Heirloom means these seeds will receive themselves year after year instead of having to purchase them again and again be sure to read your zone’s recommendations on when to plant. These seeds can be started inside and placed outside after Frost or started after Frost in your region. At the end of the season, if you would like to save seeds to move to other areas, plug the seeds and place them into a brown paper, sack or anything paper that is not plastic allow them to dry and save them for the next year. Ensure that your seeds do not get wet or moist or they will mold and go bad. Happy planting.

Great Value & Vigor
The seed pack provides a nice variety of single and multi head sunflowers. I would have liked to have a few more orange and maroon sunflowers. Thats probably my only complaint. A seed decoder on the package that gives an idea what each seed might look like, would be helpful to ensure smaller varieties aren't hidden among the giants. Germination rate was over 90%. The plants grew quickly and required minimal maintenance. Most of the plants appear really healthy. These attract bees of every size, shape, and color. A few of the flowers have flower heads that aren't fully developed. It's almost like only 3/4 of the flower opened. Overall, I'm pleased with the purchase. I still have half of the package and i expect to use them next year. My plot is about 15'x30' and we have significant wind. I haven't lost a single flower to occasional 25mph straight line winds.

Good product.
Good product. Only about 50% blossomed. The ones that did were pretty.

Good looking seeds
The seed bag was slightly smaller than I expected, however the seeds are healthy and there are a lot. I am looking forward to watching them grow in the greenhouse prior to planting them in my garden.

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.
