Red Horsechestnut or Buckeye

Does anyone have any suggestions for "more" disease resistant varieties?...mainly referring to Blotch.

Sounds like the RHC has a better flower show but the Buckeye has a better fall color.

Here are the varieties readily available. What are your thoughts?

Aesculus glabra 'Sunset'

Aesculus octandra

Aesculus x 'Homestead'

Aesculus x arnoldiana 'Autumn Splendor'

Aesculus x carnea 'Briotii'

Aesculus x carnea 'Ft. McNair'

Sort by:Oldest

I think the last introduction in your list is supposed to be better under hot conditions but stock I have seen offered here appeared to be a seed strain rather than a uniform, grafted clone.

Other than that, don't think I've seen A. octandra blotch under conditions here. It and A. pavia would be the best garden plants of those hardy in colder climates - but I think I've read comments here about the latter being defoliated early in the season in eastern (or perhaps southeastern) summers. Here the ones that often end up looking bad are A. hippocastanum and its hybrid A. x carnea.

A. Octandra looks to be the best choice in regards to blotch and scortch resistance BUT I think its going to be too big for my spot.

Hmmm...maybe Aesculus glabra x octandra 'Homestead' is the best choice? Can't find any info on the dang thing!

To throw another variable in there...there will light foot traffic under 1/2 the canopy.

Posted by smivies z5b ontario (My Page) on Mon, Jun 3, 13 at 14:51 Thank you so much for the thorough answers, If that is the case, I probably would not try then =) I Googled and learned that the buckeye and horse chestnut are extremely bitter if tried directly.

Not perfect but not bad at all. The yellow leaves it had dropped yesterday before I could snag a pic. Many Oaks, elms, and hickories already defoliated with no color change so I'm very impressed this one has hung in there as well as it has! Only 0.5" rain the two months here with highs mostly in the 90's Fort McNair 10-14-2017 https://imgur.com/gallery/2LqOJ Edit: Also to note: my a. pavia, flava, and parvilfora defoliated back in late July/August but haven't had as long as this tree to establish

You will probably get better feedback if you were to post in either the Trees or Plant Clinic forums - lots more active than this one and if we want to get picky, this is a hybrid selection, so not a native species :-)
