I have a similar one called Lola and they get 5-6 feet tall and have deep roots so they are drought tolerant suitable for xeriscaping. It is a very colorful plant, I bought mine for the wow factor. I just had to have it! Mine is getting big and I expect to see blooms this year but here is a picture from the database of the one I have. Zone 6-11, it attracts hummingbirds and is deer resistant. Both plants have tangerine at the top and yellow at the bottom. Joy Creek said zone 7,8,9, Digging Dog said hardy to zone 7, Sequim said 7-10.
