Q. Who is Mr. Smarty Plants?
A: There are those who suspect Wildflower Center volunteers are the culpable and capable culprits. Yet, others think staff members play some, albeit small, role. You can torture us with your plant questions, but we will never reveal the Green Guru's secret identity.

Title: Wildflower seeds that do well in black clay soil from Plano TX
Answered by: Barbara Medford
QUESTION:
What native wildflower seeds do best in black clay soil? We live in Plano along creek w/ 8,000 sq. ft. in full sun. No manmade water source. Suggestions?ANSWER:
This is going to sound a little flip, but looking around and seeing what wildflowers are already blooming there would be a good start. We advocate the use of plants native to an area because you already know they will grow in the area. However, maybe you didn't have a chance to observe what was blooming around your area before now, and now is when you should be seeding.
We are going to go to the Wildflower Center's list of ecoregions in Texas and select on the Cross Timbers and Prairies list. While this member of the Smarty Plants Team once lived in that area and feels that is the correct ecoregion for you, if you disagree you can go to our Recommended Species page, scroll down to "Just for Texans" and pick an area that you feel is most appropriate. Each has a description of the soils and location of that area. Here is the one for Cross Timbers:
"Cross Timbers and Prairies
The Cross Timbers and Prairies area in North Central Texas includes the Cross Timbers, Grand Prairie, and North Central Prairies land resource areas. This area represents the southern extension of the Central Lowlands and the western extreme of the Coastal Plains. The wide variances in geologic formations bring about sharp contrasts in topography, soils, and vegetation. Upland soils of both the East and West Cross Timbers are light, slightly acid loamy sands and sandy loams with yellowish brown to red clayey subsoils. Bottomland soils have small, dark, neutral to calcareous clayey areas, and loamy alluvial soils occur along the minor streams. Upland soils are dark, deep to shallow, and stony calcareous clays with subsoils of lighter, limy earths and limestone fragments. Bottomland soils are reddish brown, loamy to clayey calcareous alluvial. The North Central Prairies are interspersed with rapidly drained sandstone and shaley ridges and hills occupied by scrub live oak, juniper, and mesquite. Uplands are brown, sandy loam to silt loam, slightly acid soils over red to gray, neutral to alkaline clayey subsoils. Bottomland soils are brown to dark gray, loamy and clayey, neutral to calcareous, and alluvial."
You can see that there is a whole lot of variety, but the plants on the lists are all in our Native Plant Database, so the webpages can be checked to see what soils each plant does best in. Since they are in our database, we can take the selected list and search on it just as we would in the database. We will search, selecting on "herbs and forbs" (herbaceous blooming plants) under Habit and then, from that list hand pick some plants we consider wildflowers, go to the webpage and check under growing conditions. If you want to narrow the search down more you could designate the amount of sunlight, maybe even color and blooming time you want, but be careful - if you get too specific, you might find yourself with no selections to choose from. We will try to make a trial list for you, even checking each plant on the USDA Plant Profile Map to see if it grows natively in Collin County. Once you have gone through that drill, you should be in a position to take the same route and find plants you prefer.
When we ran that search, we got 71 results. We chose some we consider good Texas wildflowers. All that we ultimately chose had either "clay" or "clay loam" listed as an appropriate soil and all grow in or near Collin County, TX. When you are making choices be sure to read all of the webpage to match growing conditions to those on your property.
