Ulmus x hollandica Jacqueline Hillier

Ulmus × hollandica ‘Jacqueline Hillier’ is a celebrated dwarf elm cultivar selected in England for its extreme compactness and resilience. Introduced in the mid-20th century, it gained recognition for showing strong resistance to Dutch elm disease while offering a naturally dense, twiggy structure. Small, dark green leaves are tightly packed along short branches, creating a fine-textured, almost bonsai-like appearance. It grows best in full sun to partial shade with well-drained soil and develops slowly into a rounded shrub or small tree. Hardy in USDA Zones 5–8, it typically reaches 8–10 feet tall and is especially valued in rock gardens, containers, and architectural plantings.
