Description
Rubus fruticosus 'Triple Crown' trained 70 cm C2 | Blackberry
The staked Triple Crown blackberry is a supported form of the blackberry, Rubus fruticosus 'Triple Crown'. Its vigorous, upright growth has a more ordered presence when trained with support. The canes are thornless, and the plant has green leaves that fall in autumn, so it is deciduous rather than evergreen. White flowers add seasonal interest, followed by large, sweet fruits as a feature of the plant. It reaches an average mature height of about 200 cm; no mature width is specified. This cultivar is supplied as a staked plant, but the support does not make it self-supporting. It needs support as it grows, and regular pruning is also needed. The staked form can suit a garden where a supported, upright blackberry is preferred to an unsupported growth habit. Its flowers, thornless canes and green foliage give it several features to consider when choosing a fruit shrub. The name ‘Triple Crown’ is the cultivar name.

Key features of the blackberry (Rubus fruticosus 'Triple Crown')
- Flowers: White flowers appear in May and June. Their flowering period gives the plant a seasonal feature within the fruit garden.
- Foliage: The leaves are green, and the plant is deciduous. The foliage does not remain on the plant throughout the year.
- Position: Choose a sunny or partially shaded position. These options allow you to consider the light conditions in your garden when planning where the blackberry will grow.
- Soil: Humus-rich soil is suitable, provided it drains well and stays lightly moist. Good drainage is important, while the soil should not be described as dry.
- Growth and support: This is a vigorous, upright blackberry supplied in a staked form. It needs support and can be trained against a trellis or wire; its canes are thornless.
- Garden setting: As a fruit shrub, it can be considered for a fruit garden. You can browse more fruit plants when comparing plants for this part of the garden.
Uses of the staked Triple Crown blackberry in the garden
- Fruit garden: The supported form suits a fruit-garden setting. Its upright growth can be kept more ordered with support, which is needed as the plant grows.
- Trellis or wire: Train the staked blackberry against a trellis or wire. These are stated uses for this form and provide support for its vigorous growth.
- Hardiness: The supplied hardiness range is approximately -23.3°C to -17.8°C, corresponding to USDA zone 6. This figure does not guarantee the same performance in every UK garden or local condition.
- Plant features: Thornless canes and white flowers give the plant recognisable garden features. The supported, upright growth adds a more ordered presence without implying a fixed outline.
- Productivity: ‘Triple Crown’ is described as self-fertile and productive. These are useful features when comparing blackberry plants for a fruit garden.
- Ongoing care: Support is needed, and regular pruning is part of its care. The staked form is therefore not a maintenance-free option.
For a defined growing position, train this staked blackberry against a trellis or wire and provide the support its vigorous growth needs.
