Title: Annual for poor drainage area in Temple TX
Answered by: Barbara Medford

QUESTION:

What annual would you recommend for a bed with poor drainage for summer color ?

ANSWER:

The first thing we would suggest is improving the drainage in that bed. We can certainly recommend some plants that tolerate wet feet, but you will have much better success and more range of choice if you correct the drainage. It really isn't any big deal, depending on the circumstances. Is the bed directly under a roof where the water comes down in sheets on the bed when it rains? You might consider some guttering or at least putting sturdier shrubs in that space. Is it just a low spot where water naturally drains into it? Raising the bed by adding some good soil and some organic matter like compost will address the problem in most cases. Many raised beds have frameworks around them, but you can likely make do by just mixing better dirt into what is there, both raising the level and increasing the capacity for drainage. You probably have clay there, which absorbs moisture, swells up and doesn't permit oxygen and nutrients to get to the plant roots growing in that clay.

Since we don't know what your sun exposure is, we are going to go to Recommended Species, click on Central Texas on the map, and search on "herbs" (herbacebeous blooming plants) under General Appearance, "annual" under Duration, and wet or moist soil under Soil Moisture. This netted us four results, all good-looking flowers native to Central Texas. If you get the poor drainage corrected, you could expand your choices by going through the same search procedure but just not specifying soil moisture. And/or you could specify "perennial" under Duration, or not specify duration at all. Follow each link to the page on that individual plant to find out its projected size, growing conditions and propagation instructions.

Annuals for wet or moist soil in Temple TX:

Dracopis amplexicaulis (clasping coneflower) - blooms yellow April to July, high water use, part shade

Eryngium leavenworthii (Leavenworth's eryngo) - blooms blue, purple July to September, low water use, sun or part shade

Rudbeckia hirta (blackeyed Susan) - blooms yellow June to October, medium water use, sun, part shade or shade

Salvia coccinea (blood sage) - blooms white, pink, purple February to October, sun, part shade or shade
