Answer: Yucca is a member of the Agavaceae family so similar looking plants should fall into that same category. Some of the plants in this family have sharp pointed stiff leaves and others are softer and friendlier to have around. The blooming cycle of each differs and will depend upon plant maturity, soil conditions and sunlight. An excellent book to help you determine the identity of your yucca-like plant is "Succulents - The Illustrated Dictionary", by Timber Press, Portland, Oregon. ISBN# 0-88192-398-2.
