Vitex does not like wet soils. I have had very good luck with these surviving both extremes:
>Yaupon holly
>Wax myrtle
>Devilwood (Osmanthus americanus)
>Sparkleberry (Vaccinium arborea)

Alabamatreehugger, that's very useful info. Glad you told me about the vitex, because I do particularly like that one. I'll be especially careful there. I didn't know that about sparkleberries either and have been wanting to plant some of those, too. Thanks for the help!

kimmie_debris, check out High Country Gardens:

They have lots of info on xeriscape plants, and they tell you which will do well with various amounts of water. I, too, want drought-tolerant plants, but I live in the Pacific Northwest, where it is very rainy in winter and spring. Many traditional xeriscape plants wouldn't do well here, so I always check out High Country Gardens to see what I should plant.

Best of luck!

A lot of places are wet some times of the year and dry others, so plants have evolved that are adapted to those patterns. You need to find the ones that suit your conditions. I can't tell you what they are, as my own climate and conditions are different from yours, but they're out there.

Take note that a lot of spring-blooming plants that grow winter and spring, can handle a lot of dry summer weather. Daffodils and tulips, peonies and lilacs follow this pattern. A lot of the tougher roses--I like antiques--can handle both wet and dry periods as long as they don't sit for months with their roots in the water. I grow all these plants through mostly wet falls and springs and invariably dry summers, and they do fine. But I must add that they're all in ground that drains, as all our land slopes.
