When you're longing for some beautiful greenery in your yard or on your porch but don't want to introduce any nonnative species to the area, Buchanan's Native Plants is the place to go. For more than 30 years, this (relatively) little plant nursery in the Heights has been serving up offerings of native and adapted plants, everything from the usual perennials and herbs to delicate rose bushes and beautifully grown trees, while developing a loyal clientele among Houston gardeners along the way. Houston can be a tricky place to grow plants, but everything Buchanan's offers has at least a fair chance of thriving (except with those among us who simply lack green thumbs) because all its plants and trees are chosen to suit the Houston climate. Buchanan's is also devoted to organic gardening, so the nursery has a nice variety of organic options and natural soils to put your greenery in. And if you're among those who are not gifted at plant growing, it's lovely to simply stroll through the place admiring it all.
