My neighbor's solomon's seal is in direct sun all day and is HUGE. I was surprised b/c I'd never seen it in the sun before. I've seen False Solomon's Seal in the sun in the field across from my house but never the true Solomon's Seal. I would be inclined to water it A LOT until it hardens up though if you are thinking of moving a mature plant into the sun. Otherwise I would move them in the fall and let them harden naturally.

There are lots of factors to consider. In nature, the sun-shade question is not as cut-and-dried as it is in our gardens. When I've seen Solomon's seal in nature, they've been in fairly wet areas with high, open shade. In general, any plant will grow bigger in full sun--as long as it always has ample water. But that means a lot of supplemental watering, which frankly is wasteful. So you weigh a variety of factors and make a decision. After all, you can always move it.

I was eyeing some Solomon's seal at a garden center recently, and the spot I had in mind gets maybe an hour a day of direct sun, some dappled sun, and mostly shade. Ferns, native pachysandra, and hostas are very happy there. I was going to dig up a big hosta (part of my program for eliminating non-natives) and put in the Solonon's seal, but I haven't gotten around to it and now it seems like it's too late to plant anything more this year.

Elaine...it's not too late to plant...I plant all through the summer..it's just more labor intensive because when it gets hot, you have to make sure your new plantings stay amply watered.

If you've had a spring like we have had here in northwest Ohio, it's been fairly dry and cool, so we're still planting. We had a hard freeze the second week of May!

Yep, dry and cool here, too. Ideal for planting, almost. Cool and damp would be better.
