Description

The 'Navaho Summerlong' blackberry is a recent variety of thornless fruiting bramble. It produces large, black, and shiny fruits that are sweet, firm, and juicy simultaneously. They can be harvested from the second week of July until the end of August. It is one of the most productive thornless blackberry varieties. You can train or tie its upright branches to a trellis or post. Hardy and undemanding, this plant thrives in sunny, moderately moist soil.

Belonging to the rose family, the Rubus fructicosus 'Navaho Summerlong' is a selection of the variety 'Navaho' created by Lubera AG. This thornless fruiting bramble has an erect habit, with its branches growing vertically. It takes up little space on the ground for a bramble. Train its branches as they grow on a post or trellis. It can reach 2 to 3 m (7 to 10ft).
From late spring (June/July), it is covered with pinkish-white to pink melliferous flowers. Typical of the rose family, they have five petals and five sepals. Large, firm, and juicy black and shiny fruits follow them. They are sweet, juicy, and fruity. Enjoy them fresh in fruit salad or as juice, or use them to make jam, compote, or pie.
The harvest extends over the two summer months, July and August. It is self-fertile and does not require a partner to bear fruit. This variety is particularly appreciated for its yield, one of the best among thornless blackberries.

This thornless blackberry 'Navaho Summerlong' naturally finds its place in the orchard and other small fruit trees. Its upright branches give it an original and ultimately space-saving habit that suits a small garden. It is the perfect candidate to complement a rural and delicious hedge alongside 'Smokey' serviceberries with their blue and sweet berries and male dogwoods with their red and edible fruits.
