Purple raspberries

Also known as purple-cane hybrids, purple raspberries are domesticated cultivars with a mixture of red and black raspberry genes.

Most purple varieties are similar in flavor to the raspberries; however some purple varieties produce canes, and others share the growth habit of the black raspberries.

The canes are generally more winter hardy than the black parents. They tend to be very spiny and productive with large, intensely flavored berries.

The canes are prickly but not bristly, have an arching habit, and root at the tip. Leaves are morphologically variable and the flowering branches glabrous. Fruits are dark red to purple.

The purple raspberry cultivar ‘Royal’ is now widely grown in northeast China, where it is highly productive, amenable to cane burying for winter an harvested at the early stages of ripeness when it can be sold as ‘red raspberry’.

Yellow raspberries

Raspberries are easy to grow, bear their first fruits the same year or one year after they’re planted and taste great fresh or in pies, jams, spreads, syrups, dressings and sorbets. Raspberries come in a variety of colors – red, yellow, black and purple – each kind with its own distinctive flavor.

Yellow raspberries are mutations, or sports, reds and tend to be very sweet. The color is less attractive to birds, too. Yellow raspberries are variations of red raspberries and except for fruit color have all the characteristics of red raspberries.

They are grown chiefly in home gardens. Yellow raspberries bear fruits on stalks that grow directly off canes, while black raspberries and blackberries bear fruits on stalks arising on branches from canes.

Yellow raspberries are still rarely seen in stores because they are so fragile. However both red and yellow raspberries are very cold tolerant, hardy as far as Canada.
