Blackberries are not true berries. Instead, it is botanically termed an aggregate fruit, meaning it is composed of small druplets. The plants have biennial canes and perennial roots, meaning the canes only bear fruit on two year old growth. Unmanaged mature plants form a tangle of dense arching stems, called a bramble. It is highly recommended that gardeners wishing to grow blackberries use a trellis system to keep their blackberry plants in control.

Plants are pretty hardy and can grow as far north as Alaska. Since they flower late, their flowers aren't damaged by late frost, either.

They grow in every state in the United States so they're fairly adaptable. Cane berries are versatile and hardy in the coldest climates where other fruits fail.

In mild climates Blackberry plants can be planted any time they are dormant from late autumn to early spring. In colder climates they are usually planted in spring. Of course the soil should not be frozen, so the temperature should be above 32˚ F.

Blackberries are most productive when growing in full sun.
Blackberries are naturally quite drought tolerant (I have been amazed at their ability to survive months without water), but won't produce much fruit if they aren't given plenty of water during their budding and growth period. Lack of moisture when fruiting will result in smaller fruit that may not ripen properly. Water is also important after fruiting for the production of replacement shoots. Give the plants at least 1” of water per week or more if necessary.
Blackberries are very productive plants and do best in fertile soil. They can occupy the same soil for 15 years, so the ground should be amended heavily before planting.
