Need plant for sunny spot in a bird aviary

Question

I have a location in my garden that has an 6 foot high by 2.5 foot wide bird aviary (without the birds.) It sets in full sun. I would like to set a drought tolerant, colorful blooming plant or bush inside the aviary for the summer. I was thinking of an Esperanza. I can move the plant to a green house to overwinter if necessary. The location can be watered, but most plants in the same area are drought tolerant and only watered about once a week.
Would a well established Esperanza in a pot live with a once a week watering?
Would it be better off if I planted it in the ground – we have sandy soil.
Would it need to be overwintered inside?
Could you recommend another plant or bush that would be more suitable for full sun, sandy soil?
Thank you!

Answer 1

I think an esperanza would be a good choice. It is hardy to 8b, so you are right on the edge. If you think the area is protected enough, you can plant it in the ground. If the soil is all sand though, I would put it in a pot. They do need to be watered once a week, and more if it is extremely hot.
