Additional comments: In the Phoenix area, Texas firecracker is a surprisingly serviceable shrub with a light floral accent for any oasis or xeric garden theme. It strongly attracts hummingbirds. Older plants have shredding bark. The specific epithet of this plant was named after Charles Wright (1811-1885), a world-renowned botanical collector who mainly collected plant specimens in Texas, Cuba and his native Connecticut.
