Gardeners' Notes:

Grows as a hardy bush and provides good ground-level shade in our backyard tortoise sanctuary. Our desert tortoise loves to eat the white flower balls every summer! It gets some overspray from our sprinklers for our grasses, and I hit it lightly with the hose every two weeks, and it thrives even here in the 110 degree heat of summer. It is a little messy with leaf drop and seed pods each fall and is not a show-stopper. Still, if you like a more natural, grassy, prairie appearance, this is a resilient and attractive plant. It grows quickly each summer and is reduced to bare twigs each winter. That is the time to trim it back for size and shape purposes.

planted 15 seeds and most of them germinated , it takes about 3 weeks to germinate i had 10 seeds germinating. they are slow growers at first, but when they get older and tolerate more sunlight they take off fast.

They seem to be good indoor plants , i had seedlings indoors for almost 3 months and i didn't noticed any mites , aphids or any other pests . like most acacia you probably can grow this one indoors as long you can provide plenty direct sunlight.

VERY VERY drought and heat tolerant .. with the temperatures hitting 35 C , 38 C for 2 days with the sun shining on the small containers all day it didn't wilt even when i didn't water it. it also seems to fix nitrogen which is nice.

when evening and night arrives or when its very cloudy ( li... read more

I found this plant growing in a nearby area that was for cleared for a housing project. The area was raised with clay and gravel and is mowed every other month, but has been undeveloped for nearly twenty years. There are now many unusual muhly grasses and bristlegrasses that are normally not found this far east in Louisiana, along with this prairie acacia.

I first found it growing among some partridge pea sennas. It was out of bloom and I figured it was an unusual variation of the partridge pea... until I tried to uproot it. The taproot was unbelievably deep for such a small plant. I then noticed the woody base and remnants of old seed pods. It was then that I started to wonder if it was some kind of acacia. That's when I found this information.

I later... read more

I'm reading up on quail and this plant seed makes up most of the diet of the Masked Bobwhite. With careful reestablishment of native grasslands the endangered Bobwhites can make a comeback.

I have not grown this plant. Other common names for this deciduous, low-growing ground cover or subshrub are fern acacia, texas acacia, prairie acacia, Texas prairie acacia, whiteball acacia and prairie guajillo. It grows in full sun to partial shade and can be found on calcareous grasslands, rocky slopes and open woodlands. In Texas, it can be commonly found in the eastern two thirds of the state with it being it less common in west Texas. There are 3 identified varieties in Texas: var. hirta (A. hirta) - grows in east and central Texas; var. texensis (A. texensis) - grows in south Texas and the Trans-Pecos where it overlaps with var. chisosiana and var. chisosiana - found in S. Brewster and Presidio counties.
