Will it eventually stop suckering heavily as it matures, or is this a spot that I will regret filling with hostas?

==->> what suckering plant ever stops suckering..

you know the answer.. you are just in denial .. lol ..

get rid of the sumac.. and replace with a nice redbud [z3???].. and plant your hosta ...

de nile is not a river on the chicks prairie.. lol ..

That is so not what I needed to hear, Ken, but probably true.

We've had so many wet years in the last fifteen (not including the last two), that I've lost all my fruit trees and several large shade trees to drowning due to high groundwater levels. Even my scrawny sumac is hard to give up in the circumstance. Redbud is too tender for Manitoba winters, but I'll look into other possibilities.

Missing de nile,

I doubt it will stop suckering but it has never hurt my garden. I just pull out the ones I don't want. The first garden is in the shade the second is in the sun. Both are under Sumac's. Personally I like this tree because the leaves turn in the winter and I don't have many others that do. I would not want to wait for a planted tree to grow and this one takes care of itself. The sucker showing in the picture is probably only a couple years old. I'll just move it somewhere else that needs some shade if I ever get around to it. Go for it.

I planted my very first hostas underneath sumac about 30 years ago. Both are still there, although the sumac seems to have a rather short life expectancy so I always encourage well placed suckers so the main trunks will have replacements when they eventually die. The hostas I have there are the old fortunei albomarginata and halcyon, and they seem to be quite happy.

I'm glad you showed those pics,Myrle,and Jan. I now know what those trees are in my yard. I have one of my Francees near those trees,and it is thriving. Actually,that tree looks a lot like Walnut trees do here also. Thanks for enlightening me! Phil

Thank you, Myrle and Jan. Your gardens are beautiful and encouraging for the future of mine. I won't put anything too special under that tree to start. Maybe move some old standards out of premium spots and replace them with my newer purchases.
