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.

Planting and care

It appreciates deep, fertile, and rather moist soil. It is a low-maintenance plant that will be satisfied with ordinary soil that is not too dry.

Planting & care advice

  1. Growing blackberry, Loganberry and tayberry Tips
  2. The recipe for blackberry jam Tips
  3. How to make homemade blackberry syrup

Ingredients (yields about 500–600 ml)
- 500 g ripe blackberries (Rubus fruticosus agg.)
- 400 g caster sugar
- 300 ml water
- 1 tbsp lemon juice (fresh)
- Optional: 1 tsp citric acid for longer shelf life

Method
1. Wash blackberries gently and drain. Discard any bruised or mouldy fruit.
2. Place berries and water in a saucepan. Bring to a gentle simmer and cook for 8–12 minutes until berries are very soft and have released their juice.
3. Mash the fruit with a potato masher or wooden spoon to extract more juice, then leave to cool slightly (2–3 minutes).
4. Pour mixture through a fine sieve or double layer of muslin, pressing down to extract as much liquid as possible. Discard solids.
5. Return strained juice to a clean saucepan. Add caster sugar and heat gently, stirring until sugar dissolves.
6. Bring to a gentle simmer and cook for 5–10 minutes until syrup has slightly thickened. Skim any foam from the surface. Add lemon juice (and citric acid if using) and stir.
7. Test thickness by cooling a teaspoon on a plate: syrup should coat the back of the spoon. Remove from heat.
8. Pour syrup while hot into sterilised bottles or jars, seal, and leave to cool. Label with date.

Storage
- Refrigerate and use within 2–3 weeks.
- Freeze in portion-sized containers for up to 6 months.
- For long-term shelf storage, use hot-fill into sterilised jars and process in a boiling-water bath according to standard preserving guidelines.

Uses and tips
- Dilute with still or sparkling water for a refreshing drink, or add to cocktails, iced tea or lemonade.
- Drizzle over pancakes, yoghurt, ice cream or pavlova.
- For a clearer syrup, strain twice or use a fine chinois.
- Adjust sugar to taste if you prefer a less sweet syrup; be aware this reduces shelf life.
- Wild blackberries give an intense flavour; cultivated varieties are sweeter but sometimes milder.

Enjoy homemade blackberry syrup as a versatile, flavourful addition to drinks and desserts. Tips
