What is BlackBerry 'song free'

Blackberry 'Thornfree' (scientific name: Rubus fruticosus 'Thornfree') is a native of North America and is a member of the cold- and heat-resistant deciduous shrub "Black berry" of the genus Rosaceae. It is a variety.

Blackberries self-pollinate, so a single tree can produce fruit. Tree forms are available in crested, semi-upright and upright. Flowers are a good honey plant and can produce fruity honey.

Thorn-free is semi-rigid and vine, so it is cultivated with trellises or lanterns with a liner (vine). New shoots appear on the liner that extends from the base every year, and blossoms of light pink bloom in the spring to early summer of the following year, forming edible fruits in the summer.
It is resistant to cold and heat, and can harvest many medium-sized fruits in 1-2 years.
It is a variety that is easy to grow because it grows fast and is thorn-free (no thorns).
The fruits become sweet when ripe, and are eaten raw or processed into jam. The leaves are drunk as herbal tea.
