In the historic center of Oaxaca, the colonial buildings abut the sidewalks. There are no frontyard gardens.
Yet rows of agave and yucca in front of Santo Domingo are dramatic in this urban setting. Showy plants that blossom, such as the tulipan tree above, make you stop in your tracks.
Threatening thorny limbs ensure protection of whatever the shocking pink bloomer with yellow center is above. And the pink flowers profiled against the blue sky above the patio of La Biznaga probably make those best-in-the-world margaritas taste even better.
