We will be rolling out several small fixes mid-day today (Jan 29.) We do not anticipate any disruptions or problems, but f you spot any unexpected issues after 12 noon (PST), please report them in the designated thread in the DG Site Updates forum.
Yes - that's a nice specimen of Red Horsechestnut (Aesculus x carnea).
This plant is a hybrid of North American native Red Buckeye (Aesculus pavia) and the European Horsechestnut (Aesculus hippocastanum). There are several named selections of Red Horsechestnut, including 'Briotii', 'O'Neill's Red', and 'Ft. McNair'.
Weerobin, I think you're exactly right--it's a Ft McNair. My only reluctance in planting it in the landscape is the thorny nuts it drops. Can you tell me if it Drops those nuts profusely? :-)
All Aesculus sp. can form seeds, known as horsechestnuts or buckeyes - though this species (Aesculus x carnea) seems to form fewer than any of the native species, at least here in the Ohio River valley.
All the Aesculus sp. seeds are contained in a skin or capsule when maturing. On some species this skin has a prickly exterior (Ohio Buckeye is quite common, and has some slight prickles). On other species - like Red Buckeye, Yellow Buckeye, Bottlebrush Buckeye - the skin is smooth. In any case, the capsule breaks open and releases the buckeye/horsechestnut seeds often while still on the tree but usually splitting when it hits the ground.
I've never heard anyone complain or even bring up the issue of "thorny nuts." Is that something you've read about? How is the plant performing in your neighbor's yard?
