If you grow tuberous _Drosera_ from seed, they will grow on a normal
summer schedule according to your hemisphere. It is an abaxial pain
to switch hemispheres on a tuber. They insist on growing at the wrong
time. It takes about 2 or 3 years for the plant to switch seasons, and
until then they are confused and prone to die. I get about a 50%
success rate on converting southern grown tubers to the north. I've asked
Allen Lowrie what he thinks the signal is that knocks a tuber out of
dormancy, being so familiar with the plants in the wild. He gave me an
indistinct answer which indicated he didn't know either.

Jeff, that's interesting about the magnetic compass deviations near
NC. I'll ask around. I don't know geology (in my work I don't venture
from the galaxy, but avoid the solar system) but that sounds significant.
Comparing the nickel-iron meteorite vs. space aliens theory I'd have
to go the conservative route and suggest that the meteorite was brought
to the earth by the aliens.

I've never ordered from Glasshouse Works, but I like the place! Any
company that can grow and supply such an enormous diversity of plants
is ok by me. Steve, the next time you talk to them (it sounds like you
are a regular customer) ask if they carry a plant called _Desmodium
motorum_, the "telegraph plant". They've had it in the past.
