Answer: In my garden, the main central yucca will bloom and sometimes a few of the larger offsets; the offsets may take a year or two or three to build up the strength to bloom especially as the plants become more crowded. It may be that yours are devoting strength to growing in size rather than blooming. Also, if they have beenparticularly stressed for water (if it has been dry in your area) then that would make blooming even more of a luxury for them.
Seeds form within the pods (you will hear them rattling as the pods dry) and can be used to grow new plants one they are completely ripe and dry. You can also make new plants by digging up the smaller offsets from around the crown. Enjoy your yuccas!
