Title: Succulents, wildflowers and grasses for Austin
Answered by: Barbara Medford
QUESTION:
I live on a bluff over Lake Travis and am replanting two beds in front of my driveway with Mexican Feathergrass and Agave. What other grasses or wildflowers could I mix in with the Mexican Feathergrass? Ideally I would like the Mexican Feathergrass to be dominant to achieve the soft full breezy effect. Around and beneath the Agaves I would like to plant flowering Cacti and succulents. Currently I am considering Barrel Cacti and Black Lace Cacti. Will these grow together well?ANSWER:
The best way to determine if those will all grow well together is to examine the growing conditions each needs. To do this, we will go to our Native Plant Database and search on each plant. There are 14 agaves native to North America and 9 native to Texas, so we will just choose one as an example.
Nassella tenuissima (finestem needlegrass)
Growing Conditions
Water Use: Low
Light Requirement: Sun , Part Shade
Soil Moisture: Moist , Dry
Soil Description: Well-drained, acid or calcareous sands, loams, or clays.
Conditions Comments: Requires good drainage and cant take excessive moisture. Should not be watered heavily more than once a week. Goes dormant during drought and in winter. May rot under heavy mulch. Grows well in containers.
Agave americana (American century plant)

Conditions Comments: American century plant is large beautiful agave with sharp leaf tip spines. It is prominent in the landscape and best used in mass or as focal point. It also does well in pot (large) culture. It benefits from some extra moisture in very dry conditions, but is very tolerant of heat and xeric conditions. It can take light shade better than some other agaves. But should be protected from teen winter temperatures to avoid damage.
Ferocactus wislizeni (candy barrelcactus) - be sure and read the whole page in our database about this plant; our information is that it is a rare cactus and grows quite large

Obviously, we want to discourage digging up any endangered or threatened plant to move it into your garden. Also, you should be sure, if you have seen it available in retail, that it has been collected from farms for raising it and not taken from the wild. There is always the possibility that the common names in our database and those used by plant retailers are different. For instance, there are 3 other cacti in the Ferocactus genus that might be mistaken for the endangered one. You might check out the webpages on Ferocactus cylindraceus (California barrel cactus) aznd Ferocactus cylindraceus var. cylindraceus (California barrel cactus), both native to California, and Ferocactus hamatacanthus (turk's head), native to Texas. Or, in the echinocereus genus, there is Echinocereus reichenbachii ssp. reichenbachii (lace hedgehog cactus), which is native to Texas, smaller than the other and not indicated to be threatened.
For your other questions, on succulents and wildflowers for your garden, we will pick a few suggestions and you can follow the links to go to each webpage and learn their growing conditions. We have chosen these because they tolerate the same conditions as the other plants you have chosen, and are native to Central Texas.
