All are new (less than 1 year old) from North Hills Nursery, SMG, and Timberline Gardens. The rosettes from Timberline are mature and are in large clumps. The rosettes from SMG and North Hill Nursery are young. I planted all plants in pots first then moved to the bed last fall. The elongated look started about a week ago and is progressing rapidly. Our weather here in Colorado changed within a few weeks from 40-50 degrees to 70-80 degrees. The bed is on the southside in full sun. Minimal shade. I have watered every few days but only for the past 2 weeks.
This is a picture I took before the semps started elongating.
