Gardeners' Notes:


On Apr 27, 2015, SwedishDiva from Lindsborg, KS wrote:

Mine appeared spontaneously, next to the privacy fence enclosing my back yard, in the only shady spot I have. (I assume it was "planted" by a bird sitting on the fence.) I didn't even know what it was -- but searched the internet until I found it. I've watched it reappear every spring for 4-5 years. It doesn't appear to be spreading particularly rapidly, and I see a couple of lily-of-the-valley plants have appeared spontaneously to keep it company.

Got a start of this plant from my sister in Pennsylvania, planted it in my shady, moist bed along with ferns and lily of the valley, in Mer Rouge, Louisiana and it is doing well! Add Louisiana to the list of places it will grow!!!!

Excellent native woodland plant that handles heat & drought in these parts very well. A great companion is the Great Solomon's Seal(Polygonatum commutatum). Birds love the fruit and they provide nice woodland interest from early spring to late fall.


On Jan 5, 2011, gardeningfun from Harpersfield, OH (Zone 5a) wrote:

Planted in heavy clay, tons of water - it thrives here! But it hasn't spread all over. It is a nice size clump, but isn't taking over at all. So I recommend planting it in heavy clay if you don't want it to spread. Starts to come up in April and lasts for a long time! I love it!

I've been looking for this plant for a while... recently while on a hike in the Adirondacks I saw a large patch growing (in the wild). It's good to know that when/if I find some available for trade/purchase it will do well in my woodland garden.

Brooklyn Park/St. Paul,MN

I received a small clump of this plant from a friend and put them in my parent's yard in Brooklyn Park, MN. I put it in full sun/sandy soil, not knowing at the time what the name of the plant was. This was a late Spring transfer. The first year I didn't think it was going to make it. The following year it came back and spread. Every year it spreads and I have to give some away otherwise it takes over. I brought some to my house last year (St. Paul), put it in shade and it's taken off. Need to split again!

A friend gave me a start of Soloman's Seal this spring. I was very excited to see the beginnings of blooms. Yesterday we had a terrible storm with hail and high winds. Two stalks were broken down. I thought about sticking them into the ground just to see if they would root, but decided to make a clean cut and put them in a vase of water. Am I wasting my time? I really hated to toss them.

I love this plant! Easy to grow in shade. I have never found it to be invasive in my zone. And no one mentioned the fragrance in the early morning...Wonderful!

Wow, one woman's trash is another woman's treasure. I love this plant. The variegated leaves are beautiful and the delicate flowers are charming.

It certainly hasn't been invasive for me at all. I have a still very small clump from a plant that was planted three years ago. It's in shade but in a fairly dry spot which I'm sure slows down spreading some.

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!


On May 16, 2008, lemurianne from Ida Grove, IA (Zone 5a) wrote:

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.


On May 23, 2005, CatskillKarma from West Kill, NY wrote:

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.

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.

regal shade plant with slender arching stems that bear beautiful ovate-veined light green foliage. Small white tubular flowers dangle gracefully all along the stems in late spring and early summer.
