Zmeur aromat - Rubus idaeus 'Ottawa'

Rubus idaeus 'Ottawa' is a raspberry cultivar from the Rosaceae family, valued for its large, tasty red fruits and its frost hardiness. This variety is ideal for fruit gardens, borders, or even large pots, due to its high yield and quality fruits, suitable for fresh consumption or processing. It is a popular choice in cold climate regions because of its sturdiness.

Appearance of leaves, flowers, and fruits

• Leaves: The leaves are compound, with 3-5 ovate leaflets, serrated edges, medium green color, and a slightly rough texture. The foliage is deciduous, falling in winter, and forms a dense backdrop for the fruits.
• Flowers: The flowers are small, white, with 5 petals, clustered in racemes, appearing in May-June. They are modest but attract pollinators, especially bees.
• Fruits: The fruits are large compound drupes, bright red, with a firm texture and a balanced sweet-tart taste, rich in aroma. The main harvest occurs in June-July, ideal for fresh eating, jams, juices, or desserts.

Growth characteristics

• Height and width: Reaches 1.5-2 m in height and 1-1.5 m in width, forming an upright shrub with thorny stems that require support (trellis or fence).
• Vigor: Fast growth with sturdy stems, producing fruit on last year’s canes. It is vigorous and productive.
• Type: Deciduous perennial shrub, non-remontant, with a single annual harvest.

Growing conditions

• Exposure: Prefers full sun (6-8 hours/day) for optimal fruiting. Tolerates partial shade but yields fewer fruits.
• Soil: Grows in fertile, well-drained soils with slightly acidic to neutral pH (5.5-6.5). Add compost or well-rotted manure at planting to improve fertility.
• Watering: Water regularly, keeping the soil moist but not waterlogged, especially during fruit formation. Water deeply during dry spells.
• Temperature: Hardy in zones 3-8 (down to -35°C), ideal for cold climates, including Romania. Tolerates harsh winters well but mulch roots for extra protection.

Care and resistance

• Resistance: Very resistant to cold and common diseases such as leaf spots or anthracnose. May be affected by aphids or mites; treat with organic methods. Tolerates wind and moderate drought well.
• Fertilizing: Apply a balanced fertilizer (e.g., 10-10-10) in spring at bud break, and a potassium-rich fertilizer in summer for fruiting. Avoid excess nitrogen, which favors leaves over fruits.
• Pruning: Cut fruiting canes immediately after harvest (July) down to the ground, and remove weak or damaged branches in spring. Keep 5-7 healthy canes per plant for the next harvest.
• Propagation: Propagated by root cuttings, dividing clumps in spring, or by new shoots from roots.

Rubus idaeus 'Ottawa' is ideal for fruit gardens, borders, or large pots. Its red, fragrant fruits are perfect for fresh eating, jams, juices, or desserts. It pairs well with other berries or low ornamental plants like lavender. It attracts pollinators, contributing to biodiversity.

Origin

Rubus idaeus is native to Europe and Asia. The 'Ottawa' cultivar, developed in Canada, was selected for its frost resistance and quality fruits, being popular in regions with harsh winters, including Eastern Europe.

Pot diameter: 11-15 cm (varies by batch and season)
