Updated July 27, 20261 min readCited sources

A raspberry is the edible aggregate fruit of several species in the genus Rubus, especially Rubus idaeus, in the rose family. It is a perennial bramble plant grown in temperate regions for fresh consumption and processing.

What it is

Raspberries belong to the genus Rubus in the family Rosaceae. The most common cultivated species is Rubus idaeus, known as red raspberry. The fruit is botanically an aggregate fruit made up of many small drupelets, and the core stays on the plant when picked.

Key details

Raspberry plants are perennial brambles with canes that fruit on two-year-old wood. They grow best in cool to moderate climates and are sensitive to poorly drained soil. Common colours include red, yellow, black, and purple. Red is the most commercial colour.

Why it matters

Raspberries are economically important in Canada, grown commercially in temperate regions worldwide. They are eaten fresh and processed into jams, jellies, pastries, juices, and liqueurs. Their flavour and nutritional content make them a valued fruit.

In short

  • Raspberries are aggregate fruits from the genus Rubus.
  • They come in red, yellow, black, and purple colours.
  • Plants are perennial brambles with biennial canes.
  • Commonly used fresh or in jams, jellies, and desserts.
Canadian angle

Raspberries are an economically important crop in Canada and are widely grown and consumed in the country.

Quick questions

Is a raspberry a true berry?
No. A raspberry is an aggregate fruit made of many drupelets, not a true berry.
What colours do raspberries come in?
Common raspberry colours include red, yellow, black, and purple.
How do raspberries differ from blackberries?
When picked, raspberries separate from the receptacle, leaving a hollow core, while blackberries typically retain the core.
