It is a round, bushy evergreen. The flowers are broad and bell-shaped, violet, white or pale mauve in colour and have greenish-yellow flecks.

Crataegus pinnatifida - Chinese haw


The extensive hawthorn (Crataegus) genus includes an estimated 140 species spread throughout North America and Eurasia. These include more species suitable to Finnish conditions besides the hedge hawthorn (C. grayana) used so commonly throughout the country. Chinese haw is a small broad-crowned tree with shiny lobed leaves. It bears white flowers in spring, red berries and beautiful leaf colour in autumn, but is very rare in cultivation despite its attractiveness.

Amelanchier alnifolia - Saskatoon service berry

Called in the trade saskatoon or blueberry tree, the Saskatoon service berry is sometimes planted for its looks, but more often for its edible berries. Dark blue, they ripen at Mustila in early August. They have a unique taste, somewhere between blueberry, rowan and plum, with a trace of almond. The berries are sweet and almost completely without acidity, so they are often used mixed with other berries.
