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.
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.
