Q.Dwarf mondo grass
My dark green dwarf mondo has light green sprouts with balls on them. Are these new ones coming in? They are not small like the others. I have cut back and do not like the heavier light green with my deep low green ones. Are the balls the seeds? Will they come back as low dark green mondos?
Yes, the balls that you describe are the seeds. You can harvest them to propagate for new plants.
You can soak the seeds for 24 hours and remove the pulp.
The seed can be planted in a nursery tray and kept moist and warm for 6 weeks.
After the sprout you can move to a bright location.
The light color on the plant is likely the effect of the energy going to producing the seeds.
If the seeds are removed the plant should return to it's darker color.
