It is able to germinate the seeds by the way, just not as easy...

Here in Ontario, Canada its fall red/purple foliage and orange red berries are excellent view! Plants with long thorns should be trimmed. Very easy to grow in full sun to partial shade location for winter interest. The orange red berries hang on the branches through out the winter very well.

One of the best hawthorns, and one of the best trees for winter color. It fruits heavily, and the red fruit is very showy. This is one of the few red-fruited trees whose fruit usually holds up well through most of the winter. Usually the birds hold off till spring approaches.

I find the white June flowers malodorous, with unpleasant fishy overtones. A bit like callery pear.

This tree is fairly weak-wooded, and I see a lot of trees in this area with major snow damage. Fortunately, it generally seems to re-grow fairly well even after major damage.

This tree is spiny, though less so than many hawthorns---place it where the thorns won't bother passers-by.

Dirr says that in eastern N. America it's hardy in Z4-7.

It is a handsome small tree with a number of good characteristics of lovely foliage, fall color, flowers, fruit, bark, and form. It is mostly planted from landscape architects and designers, as most of the gardening public still does not really know this plant. It is realively new to the market and I mostly see young trees planted with in the last 10 years. It grows about 1.5 ft/yr as many trees do. My concern is that this lovely cultivar is the only one I've seen all over the place. More cultivars and the straight species from seed reproduction should also be used for more genetic diversity in case of some new disease, pest, or condition come along.

It is unclear whether or not the seeds need to be scarified in acid for 2-3 hours if the endocarp seems excessively tough, this practice is recommended. Seeds should then undergo warm stratification (77F) for 120 days, followed by 135 days at 41F. However, this may not produce true-to-type stock, so budding onto seedling understock is the most common method of propagation.

Autumn foliage is spectacular - gold with red and purple highlights. Fruits red-orange and are wonderful for winter interest and the bark is amazing. It peels (kind of looks like a scroll) on the trunk and larger branches.

Seed propagation may not prove true to the parent, so grafting is probably the best route.

Can be planted in the city as pollution doesn't seem to bother it.

Arguably one of the best Hawthorns for the landscape, this cultivar is nearly spineless, and its gray bark (sometimes revealing orange-brown inner bark on mature specimens) provides winter interest. The bright red, crabapple-like fruit helps provide food for the birds during the coldest months.
