Western sun cracked bark, trunk weakened, had to cut down after 22 yrs. make sure to cover trunk in winter if western sun a risk. This tree is a graft, so make sure you don’t prune your treasure away!!! Similar to trees at Niagara Falls, CA

Once established, it can be difficult to transplant because of its taproot. Plants produce viable seed.
Noteworthy Characteristics
Red horse chestnut is a hybrid (A. hippocastanum x A. pavia) that was discovered in Europe in 1812. It is a small, oval to rounded, deciduous tree that grows 30-40’ tall, and is perhaps best noted for its attractive red flowers. It features dark green palmate compound leaves with 5 (less frequently 7) spreading ovate-oblong leaflets (6-10” long). Leaflets have doubly-toothed margins. Fall color is somewhat undistinguished. Very showy red flowers appear in upright terminal panicles (to 6-8” long) in mid-spring (May in St. Louis). Flowers are followed by slightly prickly husky capsules (1.5” diameter), each typically containing two or three nuts. Nuts are poisonous.
‘Briotii’ is a cultivar that was named in 1858 to honor Pierre Louis Briot, the nurseryman at Trianon-Versailles near Paris, France. In comparison to Aesculus x carnea, this cultivar is perhaps best noted for its darker red flowers and larger flower panicles. Dark red flowers appear in upright terminal panicles (to 8-10” long) in mid-spring (May in St. Louis). Flowers are followed by slightly prickly husky capsules (1.5” diameter), each typically containing two or three nuts.
Problems
Leaf blotch can be a significant problem. Powdery mildew and leaf spots may also occur. Bagworms, Japanese beetles and borers are infrequent but potentially troublesome. Leaf scorch (brown edges) may occur in droughty conditions or on sites exposed to wind. In general, this tree has better disease resistance and its foliage is less apt to depreciate as the growing season progresses than is the case with A. hippocastanum.
Garden Uses
A beautiful landscape tree for parks and large lawns. Depreciation of the foliage during the growing season due to disease, insect and scorching problems somewhat limits its value. Often not recommended as a street tree because of litter problems (nuts, twigs, leaves). It may be planted as a shade tree.
This plant has proven quite tough even as it was in constantly wet soil for a couple months followed by completely dry soil for a couple ...Read Moremonths after its planting. Here in central Illinois it tends to flower starting in late April through mid to late May. I would expect a good three to four weeks of flowers from this tree depending upon the weather. We had a light freeze in late April and it didnt affect the flowers or foliage a bit. Come summer there is a bit of leaf browning from disease but it doesnt become a significantly noticable problem. Briotti provides a truly rare flower color for a tree growing in a temperate climate, and makes an excellent shade tree when its gotten to a more mature size. A foot of growth is considered good for one year. *UPDATE 4-5-07* We are experiencing lows around 20 for nearly a week, after nearly a month of lows above 45 degrees. We didnt experience any frost this week but the really cold temperatures did completely wilt and shrivel the new growth of the past month, including the flowers. It does somehow appear that maybe 6 out of 20 flowers somehow survived the extreme temperatures.
