IMMORTALITY fans in two different beds about 10 feet apart. The one
with larger leaf blades is more heavily mulched, on gravelly loam; the
other just starting new growth is nearly pure clay. Both were mulched
with chip mulch last spring.
I'm not surprised that the fans on gravel have started fall growth
sooner than the ones on clay - it takes a lot more water to wet the clay
enough to benefit the plants than it does on gravel.
Fans in both locations had fewer than 6 green leaf blades this summer,
probably around 4. If they don't get frozen out, these might go on to
bloom this fall.
Does Immortality put on a burst of growth like this once the weather
turns cool in the fall in other locations?
I don't irrigate, but used to water these clumps frequently to see if
that would trigger more bloom - it didn't.
