Take a horticultural tour of Texas at this gracious 38-acre garden, encompassing everything from south Texas scrub to Hill Country wildflowers. Fountains, pools, paved paths, and examples of Texas architecture provide visual contrast to the flora. The formal gardens include a garden for the blind, a Japanese garden, an herb garden, a biblical garden, and a children's garden. Perhaps most outstanding is the $6.9-million Lucile Halsell Conservatory complex, a series of greenhouses replicating a variety of tropical and desert environments. The 1896 Sullivan Carriage House, built by Alfred Giles and moved stone-by-stone from its original downtown site, serves as the entryway to the gardens. It houses a gift shop (tel. 210/829-1227) and a restaurant (tel. 210/821-6447) offering salads, quiches, sandwiches, and outrageously rich desserts, open Tuesday to Sunday from 11am to 2pm.
