Boston Ivy 'Robusta'

Boston Ivy 'Robusta' (Parthenocissus tricuspidata 'Robusta'). Parthenocissus tricuspidata 'Robusta', known as Boston ivy 'Robusta', is a more vigorous selection with broader foliage than 'Veitchii'. Its trilobed leaves are significantly larger, creating a more textured and less strictly flattened effect. However, it still maintains excellent adherence thanks to its suckers, but produces a thicker and slightly less formal covering. In summer, its bright green foliage is dense and opaque; in autumn, it turns luminous bright red. This variety is particularly suitable for large facades, massive structures, and projects requiring a rapid spectacular effect.

To plant Boston ivy 'Robusta', choose an appropriate exposure: full sun to partial shade. The recommended soil is well-drained and tolerates various soil types. Water the root ball before planting it in the ground and ensure that water can drain after planting. During establishment, check the moisture by hand before watering again. Spread mulch around the base, leaving the collar clear. Avoid systematic fertilizer applications without considering the soil's richness. In Quebec, choose a period when the ground is thawed and easy to work with.

Allow a width of 6 m (20 ft) to plan for this plant's space in the garden. The indicated height of 15 m (50 ft) helps choose its position relative to neighboring plants. Keep access to the base for weeding, checking moisture, and removing damaged parts. Pair this variety with plants that have compatible light and water needs. If you are considering a container, first check that its volume and drainage are suitable for root development. Roots in pots are more exposed to cold than those planted in the ground.
