Fern-leaved Buckthorn 'Asplenifolia' (Rhamnus frangula 'Asplenifolia'). Rhamnus frangula 'Asplenifolia', also known as fern-leaved buckthorn, captivates with its very fine, deeply cut foliage, reminiscent of ferns. This light, textured foliage turns golden yellow in autumn, extending its visual interest. In summer, it produces small, discreet flowers followed by decorative black berries appreciated by birds. Ideal for informal hedges, naturalistic gardens, or woodland borders, it is hardy, tolerant of moist soils, and brings unique structure and texture to the landscape.

To plant fern-leaved buckthorn 'Asplenifolia', choose a suitable exposure: full sun. The recommended soil is neutral to slightly acidic, well-drained. Water the root ball before planting and ensure water can drain after planting. During establishment, check the moisture by hand before watering again. Distribute mulch around the base, leaving the crown clear. Avoid systematic fertilizer applications without considering soil richness. In Quebec, choose a period when the ground is thawed and easy to work with.

Allow for a width of 2.5 m (8 feet) to plan the placement of this plant in the garden. The indicated height of 3 to 4 m (10 to 13 feet) helps choose its position relative to neighboring plants. Maintain access to the base for weeding, checking moisture, and removing damaged parts. Combine 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.
