You probably don’t think of roses as a low maintenance or low water plant for Texas, but you’d be wrong. Cinco De Mayo Rose is a heat loving, sun bathing, non-stop bloomer for hardiness zones 6-10.

Another rose worth noting is the Peggy Martin climbing rose. She’s a big momma that needs a lot of room and support to be all she can be, but she’s worth the real estate. With pink to white blooms each spring and summer, it is well know for its ability to withstand extremes after being covered by water for months after hurricane Katrina. Low water, low maintenance and a show stopper in the garden. 20’ x 20’ evergreen and delightful.

My all time favorite vine for Central Texas is the Evergreen Wisteria. Not to be confused with the invasive Asian variety, this one is a repeat bloomer that’s fragrant and stunning with its facial and magenta flowers and dark green, glossy leaves. Reaching to 20’ it makes a great fence cover or arbor plant. It doesn’t have tendrils so it needs some support.

Daylily is a plant that comes in a plethora of colors and sizes and I don’t think you an have enough of them. Stella De Oro is a great variety for zone 8, but I encourage you to experiment and see what works best for you. Low water, low maintenance and loves the sun.


The last two are a couple of tree that I use often in my landscape designs for good reason. The first is Desert Willow and it easy to see why. With fragrant pinkish-plum flowers and long thin leaves it welcomes the heat and sun and seems to thrive in it. Reaching to 20+ feet with a willowy shape and open branches, it’s a beautiful specimen that breaks the mold.

Last but certainly not the least is Anacacho Orchid Tree. This small tree is really special because of its funky split leaves and fragrant white flowers. She’s deer resistant, super drought tolerant and grows to about 12’ over time. I’ve seen them round in shape or tall and thin and no matter what shape they take, they’re a welcome addition to the xerophytic landscape.

The truth is, I could have kept going! Sun is where the color lives so experiment with some new colors this year and remember to give them plenty of room to grow and show.
