Anyone with an interest in Texas' flora and fauna should make the 20-minute drive to the wonderful gardens of the Lady Bird Johnson Wildflower Center, southwest of downtown Austin. The center, founded in 1982 with the assistance of Texas' beloved former first lady, has a display garden featuring every type of wildflower and plant that grows in Texas, separated by geographical region, with an emphasis on Hill Country flora. The best time to come is in the spring (especially National Wildflower Week in May), but there's something in bloom all year.
