My bushes here in San Antonio, TX have reached a full 3ft. tall by 2ft. wide with a nice shrubby shape. They take regular shearing very well and would make a very nice low-growing hedge. This is the easiest rose to propagate by root cuttings I've ever seen - you just cut a piece off, strip off the leaves, stick it in some potting soil or in the pot of another container plant on your deck, and voila, a new rose in a couple of weeks. Considering how easy it is to propagate this rose, this would be a very economical hedge to create from the purchase of just one rose. I imagine it would be especially attractive as a long hedge growing along a hot driveway, which is where mine grow and thrive.
Martha Gonzales is an amazing rose - she has no scent but makes up for that with toughness and continual bright cherry-red blooms that really brighten up the landscape. The foliage is small-leaved, has a lovely purple hue, and is very healthy and disease-free. This is a great rose for alkaline or rocky/difficult soils and dry sunny spots.

Zone 8 coastal south. I have 3 of these. All three bloom repeatly through the summer, even during the dog days here. Slight blackspot but the rose shakes it off.
This is just a fantastic plant/shrub for Texas. Cute as a button, new growth tends to be darkish foliage, has a sort of Victorian/'eclectic' look to me. Fairly drought tolerant and disease resistant. Super easy to maintain, just give it a light trim in late winter/early spring if desired. Can also be shaped into a low hedge.

This rose has done very well for me (zone 8) in central Texas. In this area it has had no problem with mildew, black spot or insects. My experience with it is very positive - a great little rose.
