Deb, I was thinking along the same lines as Linda late last night.
I have two lavenders down in one of my street beds, which is actually my storm drain that have survived a very wet winter this year. They are planted in very poor soil that drains quite well.
We got forty inches of rain this winter. Our climate is accurately defined as a "wet Mediterranean" climate. We can have very wet winters and springs and no rain during the summer months.
That is the last bed I get to for spring clean up chores. Most of the time, that bed gets neglected and gets little care.
