LW,
Spanish lavender does very well here under almost any conditions. I have grown both the French and Spanish versions (in fact the 2 are sharing a pot in my yard now.) and even in the furnace blast of summer they do well in full sun as long as they have sufficient water.
HTH,
Trudi :0)

I have 5 spanish lavendars lining my sidewalk. They are in my lawn area. To protect a little more from the weedeater, I dug a hole - cut the bottom off of the container it came with and put the whole thing in the ground. They are on drip irrigation, watering about 10-minutes every other day. The first summer offered very little growth or blooms. This is the second year & they are BEAUTIFULLY in bloom right now. Beware of the bees - I have tons. But they won't bother you as long as you let them have the lavendar all to themselves. I highly recommend this plant, and as soon as I have the gumption to put the drip lines into the ground on the other side of the sidewalk - I'll plant 5 more!
