That does not sound right. Neither will be grafted if you are buying the straight species. I think the cultivars of redbud are grafted (e.g. 'Forest Pansy') but only to seedling redbuds. They would not be grafted to a maple.

Agree with the above, there is really no concern. A maple would not be a rootstock for either due to species incompatibility. And even many named forms of these trees are propagated from cutting instead of being grafted.

Lol this is funny

LOL Thanks for the advice...medical and horticultural. The less that the nursery staff know, the more extra strength Tylenol I need :/ I've decided to get a serviceberry. I'll drive 1 1/2 hrs. to the east to get the tree. In a few weeks, I'll drive 1 1/2 hrs. to the west to get hostas. Luckily, I never have trouble picking out hostas.

I planted a redbud tree last year "near" where i will have hostas. After doing a little research on the root system, it may have not been the best tree to put in. Hind sight is 20-20 :(

I've got Eliator and Gold Regal under a seviceberry I ripped out of the woods about 10 years ago....no problems.....it's about 15 ft tall now

plain old redbud are seed grown ... and perfect trees for hosta...

i wouldnt be surprised if some of the foo foo RB are grafted ... but they would be grafted on redbud ... crikey you got some bad info .... criminey.. RB grow like weeds why in the world would you graft onto some other species.. and besides that.. AN UNRELATED SPECIES ...

find a better nursery.. or find the manager.. and see if he or she knows what the heck they are talking about ...

back in 2000 van wade.. one of the hosta gods.. sold me a dozen redbud to plant hosta under ... if he said they were ok.. then good enough for me ..

ken

btw... the foo foo RB are variable in z5 .... either not very aggressive [slow growing] ... or they die.. depends on your version of winter in z5 ...

I've been contemplating a redbud in one area for a couple of years. Thank you for starting this thread and all the information here.

In this area, it's the Eastern redbud that does well. Cercis canadensis

Thank you all for sharing info. and your experiences. Once again the hosta forum community has come to my rescue. If you say it's ok...then good enough for me!

Amelanchier x grandiflora is great to grow hostas under. Deep-rooted. The bonus and drawback are the berries in June. If you get them before the birds, then great. Otherwise either the berries drop onto your hostas for two weeks (either before or after passing through a bird's intestine).

Oh, and there are some trees that might be grafted onto stock of a different member of the genus, but rarely (never) something outside the family. So perhaps an Amelanchier could be grafted to a crabapple, or a Cercis to God-only-knows what (most of its tree relatives are tropical), but it wouldn't make much sense. But a maple??? Dude!

I'm having good luck, so far, gardening under my redbuds. I have several serviceberries too, and again - so far, so good!

If you can plant the serviceberry where you can watch out the window - the birds have a great time with the berries... people can eat them too, but the birds usually beat you to them. My husband managed to snag one last year and said it tasted good. We have a couple near the screened porch and its great fun to sit there and watch the robins. They truly strip ours clean of all the berries.
