Blackberries are a purple/black fruit, oblong in shape, growing up to 1.5 inches in length. They are semi-soft and, depending on variety, range from tart to sweet in flavor and usually contain seeds.
Gooseberries, also known as Ground Cherries, are enclosed in papery husks, much like tomatillos, to protect the fruits from insects and cushion them when harvested.
Raspberries are a small, delicate soft red fruit. Each raspberry is composed of many small individual sections, each with its own seed surrounding a central core.
