RASPBERRY

(Rubus idaeus)


The raspberry is common throughout forested areas of Manitoba, but it is more abundant and grows more vigorously in deciduous forest regions of the southwestern 1/3 of the province. It grows best along forest edges in rich, moist soils.

Raspberry plants are low shrubs (to about 1 m in height) that spread aggressively by underground rhizomes. New shoots, called canes, develop from the spreading rhizomes each year. The new shoots will not produce flowers or fruit in their first year. It is the 2-year old canes that will flower and set fruit, and these often die after bearing fruit. So the lesson is: "Don't cut down all the raspberry canes, or you'll have to wait 2 years to get any fruit."

It is usually mid-June before raspberry bushes will be in flower. The distinctively shaped and flavoured raspberries ripen by late July and can be harvested until late August. The bright red raspberry is an aggregate fruit made up of tiny "drupelets". Raspberries are delicious raw or cooked, and make excellent jams and jellies. The only draw back to them is the abundant, tiny hard seeds that can get stuck in you teeth and make jams "crunchy". Besides humans, many birds and mammals will dine on wild raspberries.
