I just checked the topo of
the underwoodii site I had in mind near Alexander City, AL, and the
elevation is just over 600 feet. Those plants came up here a good 2.5
months after the Florida panhandle underwoodii - and they are less than 200
miles NW of them as the crow flies. Thinking about it more, I've seen
similar effects in decipiens - the forms just north of the Florida border
come up here way before those from central eastern AL, and the distances
between populations are even less.
How long have the respective accessions been growing in your garden, John?
Perhaps their timing will synchronize gradually over some years? I've
certainly noticed different timing of emergence between bulbs brought here
in fall and the same bulbs a couple of years later, when they've settled in.
