There are many cultivars of raspberries, including red, yellow, black and purple. The broad division is between the habit of a plant for fruiting, based on the age of the canes within the season.

Some varieties of raspberries bear fruit only in the summer from second-year canes from the previous season.

Other varieties of raspberries may bear fruit both in the summer and the fall, but can be trained to emphasize one or the other season, based on the growth of specific canes at the beginning of the season. It turns out that the labels for additional canes I purchased didn't indicate their habit, but at the end of the first season I noticed fresh raspberries.

The canes I grow are quite vigorous and put out numerous canes, so I plant each crown about two feet from the next.

I didn't have a choice on where to transplant the crowns but the soil is well drained and of poor quality, requiring amenments, just as with all the soil in the garden area.
