Angelonia angustifolia
The White Angelonia is very suited to the Texas climate it is one of the easiest plants to grow. There's no need to purchase the larger container because after about 4 to 6 weeks it has more than doubled in size and for the remainder of the season, it continues to multiply. Angelonia's come in a variety of colors. I've seen them in red, white, purple, and pink. They are also known as Summer Snapdragons. They like well-draining acidic soil. Angelonias are considered a perenial.
The ones below in the pot were a purple color. I started with a small $3 container and by the end of the season, the Angelonia was too large for the pot.
