Title: Care of Spanish Dagger (Yucca treculeana) after blooming
Answered by: Jimmy Mills
There are several plants known as Spanish Dagger, but the one you have is most likely Yucca treculeana (Don Quixote's lace). Each flowering stalk produces only one set of blooms, so unless you want to collect mature fruits and seeds, go ahead and remove the old flowering stalk.
More botanical information about Spanish Dagger can be had at this link, and to find learn about historical human uses of the plants, click here.
