Dr. Deno says this about L. maculatum:
Lamium (Lamiaceae).. L. maculatum seems to require light based on a
small sample as shown by 70L(2/1 1 in 4th w) and no 70D(none). These results are for
seed DS 6 m at 70. This species self sows here, but seed ripens over a long period
and is hard to collect.
I see 99 other Lamiums in the ATP plant database,
http://garden.org/plants/brows...
including one entry for Lamium sandrasicum
Lamium sandrasicum
But I don't see instructions.
Someone grew this one from a cutting:

That's all I could find!
