I was given a few clumps of this plant about 5 years or so ago. It was VERY slow to take off in my NJ shade areas. Just last year it make a nice clump and started to spread. I divided the clump into 5 or 6 individual plants and replanted throughout my shady area. I am hoping that each will start to make a clump, it is one of my favorite early spring perennials! It is planted with hosta, dwarf astilbe, sweet woodruff and ferns. I didn't know the name of it until I came here today to see if I could find it somehow! Yay!

I hate this plant! It is EVERYWHERE in my yard -- sun, shade, nestled among tree roots, under my sidewalk(!), everywhere! Highly invasive and not especially attractive, I'd definitely suggest caution to anyone thinking about planting this. At the back or in the middle of perennial beds it isn't so bad, but it won't stay there! Everywhere that I've dug to plant this Spring has been infested with polygonatum biflorum's huge rhizomes. I'd pay money to be rid of it.

Solomon's seal grow's wild everywhere here in the Catskills. The biflorum part of the species name is because the flowers of true Solomon's Seal grow in pairs along the leaf axils. I have some of the giant cultivar (3-4 ft) variety growing in a shady seating area in my yard as a memorial to my late pet Rhodesian Ridgeback Solomon. It is in bloom now, at the same time as some bleeding heart, which complements it well. Grows well with ferns and hostas, too.The area is shaded by swamp maples.

In spite of the species denotion "biflorum", this plant can have from 2 to 10 blooms hanging from the leaf axils. The larger the plant, the more flowers it produces (in my experience). Oddly, the plants in more open, sunny locations are often smaller. The big ones are in deep shade, usually smothered under poison ivy, LOL. My big ones average 5 blooms per axil. I will try to get a picture when my DH gets back with the camera.

Edited after some research. Evidently, a person by the name of J. T. Kartesz lumped three previously distinct species ( Polygonatum canaliculatum, P. commutatum, and P. biflorum) into this one category in 1994.

I think this was a mistake, since the species are so very different in size and flowering characteristics. I am going to post my pictures of giant Solomon's Seal under another listing (P. biflorum var. commutatum):

If I ever get to take pictures, LOL.

A neighbor gave me a couple starts several years ago. I planted them in a moist shady spot and they've taken off like they've always been there. No special treatment, no real care. And it's beautiful in flower, foliage and even fall color!

Hi - responding from St. John's, Newfoundland, Canada - Solomon's Seal transplanted well and is spreading like a much-desired weed in our shady, moist garden. Just finished blooming in fact. Can't wait to see what happens with it next season!

Great plant for shade, and not hard to get a clump started.
