Notes

A small hawthorn species that has been shown to have good disease resistance and is very adapted to Colorado. High wildlife value and is a good replacement in the urban landscape for our native hawthorns which often have many more disease issues. Like other hawthorns it is thorny but not significantly. Attractive fruit.
