Lorraine Sunshine
The variety 'Lorraine Sunshine' is so completely different that I may give it its own page at some point. It gets mixed reviews from fellow gardeners; I haven't observed it for long enough yet to have an opinion. Its standout feature is striking leaf variegation, with dark green veins on an off-white background. We grew ours from a batch of traded seed; only some of the seedlings displayed the variegation, and even those may not be the same as the real cultivated variety - but I bet they're close. The whole plant is much less vigorous than its wild brother. Even as seedlings, they were weaklings, succumbing much more quickly to drought than the plain-leaved ones arising from the same seed lot. Now in their second summer, our two surviving plants have not grown taller than about a foot, while just a few feet further on, the species is already at three feet tall and still going. All of which isn't good or bad - it's just a different plant that will need different conditions and placement to bring out its best.

In our garden, this plant grows in the following areas: back yard island, curve garden (both lobes), driveway bed, sale plot

Seed for this plant is included on my seed trade list

Light is helpful. So is selecting the plumpest seeds you can find.
