Got some seeds not knowing what i am going to get. From the pictures is a interesting species and cultivar. The seedlings started really bad... i wanted to throw them away because i saw that they were suffering and i didn't know what to do. But i kept them. When a leaf has grown large enough to be sniffed...i couldn't stay away. Sniff sniff...and bang! It hit me. One of the most amazing of smells i ever sniffed: a mixture of english lavender and orange thyme with a balm touch. I knew right away why it is named "lavender haze".
I transplanted them to 4 per pot (9 cm) and didn't do least with the leaves: were hard and crisp because of the heat and N low levels. But the blooms...oh the blooms... fantastic! tiny long flowers in an over saturated stem. It was suffering so i pinched the flowering stem after a few nods. But flowered, and flowered, and flowered.

This species/cultivar has a very compact habit, so it's best grown in that kind of long pots so the plants can make a "flower fence" anywhere where you put them. But i think that even in soil does very well. In winter becomes dormant and i don't know if it can resist in zone 6b. Probably with mulch and low humidity it can. So it's best to be "hilled"(make a trench in a 5 inch radius on all the sides of the plants without harming the roots and put some plastic foil above the hill and ancor the foil with some stones in the trench so that water is drained very well from the plant in winter rain/snow). Don't forget to make some tiny holes in the foil for the soil to breathe.

Overall experience with this plant: I recommend it to all sniffers/gardeners!
