It is more common now I see them in Toronto as trees on the street and parks those public areas, rows of them.

It is quite pretty when they are blooming! Very easy to grow!

Easily grown in average, medium moisture, well-drained soils in full sun to part shade. Prefers moist, fertile soils. Foliage tends to scorch and generally depreciate in dry conditions. 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.

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 months after its planting.

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 experien... read more
