Spanish Dagger TreeThe Spanish Dagger (Yucca Treculeana, Carr.), of Texas, has blue-green leaves, which are lanceolate and rough on the under side. The flowers of this species are brightly flushed with purple. It grows wild in considerable areas, a striking feature of the landscape, and is common in Texas gardens.
By these two species the characters of the genus are exemplified, and the remaining seven species will readily be referred to the genus. There are no other trees likely to be confused with yuccas.
