Firethorn is in fact covered with sharp thorns, so be careful planting or transplanting a large specimen. Pyracantha 'Orange Glow' can reach 10' tall and 12' wide, although there are other varieties that are more compact (and also varieties with red fruit).
A favorite use of pyracantha is as an espalier, and up against a wall can be trained into many different shapes. Firethorn is a fast grower, and can also be used on slopes to help with erosion. It can be pushed in to the shade, but will flower and fruit best in full sun.
