Longwood Gardens West Conservatory
A new 32,000-square-foot conservatory by WEISS/MANFREDI houses an immersive Mediterranean Garden by Reed Hilderbrand, featuring planted islands, pools, canals, and low fountains. West Conservatory’s asymmetrical, crystalline peaks appear to float on a pool of water, while inside, our unique garden under glass evokes the character of the Mediterranean, where both wild landscapes and cultivated gardens express an inseparable relationship between water, stone, and plants.
The pools, fountains, and planted islands of this garden honor P.S. du Pont’s fascination with water in the landscape in an entirely new kind of garden within Longwood’s set of conservatories. With a focus on a permanent collection of plants, the West Conservatory celebrates the particular beauty of species that thrive in the Mediterranean’s dry climate, expanding understanding of one of our planet’s most diverse ecozones — its beauty, mutability, and resilience.”
A MEDITERRANEAN TAPESTRY
Inspired by the gardens and landscapes of the six global Mediterranean ecozones (the Mediterranean Basin, South Africa’s Cape Region, coastal California, Central Chile, and Southwestern and South Australia), the West Conservatory garden incorporates three planted islands set on an expansive sheet of water.
Cast stone paths and bridges hover above the plane of the garden and lead to brick terraces for gathering and pausing. Together these features draw guests through a rich juxtaposition of plants, stone, quiet water, and animated fountains that evoke characteristics of the Mediterranean landscape while alternating experiences of intimacy and openness.
Sixty species of plants compose the tapestry of the permanent garden. Drifts of low shrubs and perennials carpet the islands, many with tufty, billowy forms and small leaves that reflect the plants’ response to the scarcity of water, infertile soils, and windswept conditions of this ecozone. The composition includes a range of iconic plants: Agaves (Agave), Aloes (Aloe ‘Johnson’s Hybrid’), Blueblossom (Ceanothus griseus var. horizontalis ‘Yankee Point’), and the tiny pink flowers of Deltoid-leaved Dewplant (Oscularia deltoides) that hug the ground. A slightly taller shrub layer expands the garden’s texture and includes the evergreen pincushion shrub (Leucospermum ‘Brandi Dela Cruz’); the dense Egg-and-Bacon plant (Eutaxia myrtifolia), which is known for its two-toned yellow and red-brown flowers; and the aromatic Prostanthera rotundifolia known for its fragrant purple flowers.
Rows of Cypress (Cupressus sempervirens) and Bay Laurel (Laurus nobilis) move through the drifts, framing spaces and gradually disclosing the garden. Trellis structures covered in espaliered citrus define each end of the garden. Vine structures cantilever over and shade the south walk. Canopy trees, including acacia (Acacia salicina) and palm (Bismarckia nobilis), take advantage of the conservatory’s height, providing shade for visitors below. Above the east and west entrances, more than 60 baskets of the trailing succulent Baby Burro’s Tail Sedum (Sedum burrito) hang like blue-green clouds, drawing visitors’ eyes to the soaring supports and arched roof of the conservatory. Throughout the year, a series of 90 seasonal plant species will be introduced throughout the permanent plant collection, expanding bloom and diversity within the garden.
