Re: Update of yucca hybrids progress
Your plants indeed look very nice and healthy.
The reason to offshoots can be because you have planted some of the Yuccas very high, so the base of the plant is visible.
Another possible reason could be, that the young plants have been grown for a too long time in a too small size of pot. Potted Yuccas very often starts growing shoots from the rhizomes below when grown in small pots.
Happy Yucca growing
