For when you get demoralized thinking about all the things you can’t grow under your black walnut, take heart. This venerable black walnut tree, located at Green Spring Gardens in Alexandria, VA, holds court over a lovely planting of magnolias and shade perennials:
I did not check to see if the magnolias were marked, but they are probably a cultivar of M. soulangeana, and they are pretty glorious right now.
Underneath was a comely mixture of bear’s foot hellebores, other hybrid hellebores, Japanese Shield fern, and Virginia bluebells:
This bed would be the envy of any woodland gardener, so those of us with black walnuts should not be feeling sorry for ourselves. I will say that the folks tending this garden add quite a bit of shredded leaves to their beds, which makes the soil nice and fluffy and the plants plenty healthy. My gut tells me that healthy, rich, organic soil tends to counteract the effects of juglone for plants that might be semi-susceptible.
However, I personally have hellebores, ferns, and bluebells growing very robustly under my black walnuts in terrible, dry soil. So I think these plants will grow well even if you don’t give them perfect duff.
What I’m rrrrrrreally jealous of with this garden bed is that mid-layer — the magnolias — which connects the ground layer to the big black walnut and pulls it all together. I have not had as much success getting small ornamental trees to survive with my BWs….maybe I need to put M. soulangeana on my shopping list….
Definitely a “come hither” tree when in bloom:
I’ve got plenty.
And plenty still to come:
This is a nifty nut collector made by the folks at Garden Weasel. What a treat to discover a yard device that requires no engine and makes no noise, that is so simply designed and yet works beautifully.
Just roll it along the ground and the nuts become trapped in the wire cage. To release them you push a doohickey on the handle (like when you squeeze out a mop) that spreads the wires so the nuts can fall out again. The only trouble is that there SO MANY NUTS and collectively they are very heavy. A plastic trash can should only be filled about a quarter full; otherwise, there is risk of it busting wide open as it’s dragged (ask me how I know).
Still, I never tire of this canopy:
And there are some other pleasant distractions from the tyranny of the black walnut trees. Some toad lily and sedum:
The Winterberry holly never disappoints:
Bottlebrush Buckeye fruit:
Some white wood aster:
Zigzag goldenrod, now fading:
This cute little bottle gentian that I nearly ripped out over the summer thinking it was a weed:
A Japanese combo — bloodgrass and anemone:
This year’s crown jewel — a Red Abissynian Banana. I adore it so much! The leaves are insane!
This lantana and bloodgrass was a good combo:
This lantana was so exuberant this year that it shaded out my herbs:
Elephant ear and celosia refusing to back down in the face of autumn:
I have a vivid memory of eating a Red Delicious apple when I was seven years old and, afterward, regarding the dark seeds embedded in the core. Continue reading
More good news for those of us living with Juglans nigra! In his new book The Layered Garden, David Culp describes several genera that he has grown with success beneath these anti-social trees, including:
Smilacina — (Smilacena racemosa — False Solomon’s Seal — an interesting perennial with white flowers in spring followed by green/red berries).
Asarum — (cute little gingers!)
Aucuba — (Evergreen, Gold Speckles. Reminds me of the upholstery on the couch from my childhood family room, circa 1976. What’s not to love?)
Pulmonaria — (I am always reading about how great these are — why don’t I grow them?)
Convallaria — (I actually have Lily-of-the-Valley growing under a Silver Maple, which means they will officially grow anywhere.)
Isn’t the weedy Hellebore bed with wire fencing just super classy? It’s my patented “Postmodern Retro Tacky” design aesthetic.
No, those aren’t dirty tennis balls. Those are just a few dozen of the THOUSANDS of black walnuts that rain down on my backyard at this time of year.
Check out the little cutie I stumbled upon at Green Spring Gardens’ plant shop a few days ago:
What you’re looking at here, my friends, is a baby Paperbark Maple (Acer griseum) which (in case you’ve been living in Antarctica or something) you know is one one of the most coveted of ornamental trees.
Well, the minute I saw this little guy I knew it was coming home with me. When I worked at a local nursery a few years ago, 5 to 6 foot specimens of A. griseum were selling for close to five hundred Big Ones. They must be a bit more readily available now, and I know this one is a runt, but I couldn’t walk away from the $15 price tag. Plus, if you look closely at the tiny little trunk, you can see the bark already exfoliating! Awwww!
Never mind that I have no place to put it. No sir, not even close! I’ve already used up the three sunniest locations in my backyard with other ornamental trees that I yearned for (a river birch, a silverbell, and a sweetbay magnolia). And my front yard is spoken for as well. It already contains two large trees and three small ones. To try to throw the new Acer into the mix would just be disrespectful to all involved.
So I’m doing the noble thing and giving it away to a family that can give it a decent chance in life (my mom and dad). Their backyard has the sun and space that I simply cannot offer it at this point in my life. It pains me to give it up, but I know I am doing the right thing and giving it the greatest chance to fulfill its destiny!
Plus, maybe my parents will let me come over and water it sometimes. Sniff.
Do you garden under a Black Walnut tree? Have you searched the internet seeking lists of species that grow under Black Walnuts only to discover that the lists are sometimes contradictory, or that (even worse) they are waaaaay too short to satisfy your jonesing for plants?
Is your Black Walnut tree interfering with your gardening pleasure, making you irritable, or adversely affecting your overall life enjoyment quotient?
Have you cut down a Black Walnut tree or had thoughts of cutting one down?
