I just bought 2 packets of these at a local Gardening center not more than a month ago - check around I'm sure you can find them - if not check here you can order from this website

I have seeds for Lavender 'Munstead' and or 'Vera'....I'm just not sure where I planted what anymore in the yard! Either way from experience all the babies that have arisen from under/near all the plants have come true to parent.
If you like I could also arrange to send you a few baby plants come spring....there are plenty babies now out there and there will be plenty new ones (smaller of course)coming up then too. Let me know :)
