Along the Agulhas Plain, where the wind shapes the dunes and the salt air burns the edges of the land, stand the white milkwoods (Sideroxylon inerme). To most passers-by, they are familiar figures—gnarled trunks, glossy green leaves, broad crowns twisting toward the sea. Yet these trees are far more than coastal scenery. They are survivors of wind and drought, anchors of soil and shade, and living links between natural and cultural heritage.
At Lomond Wine Estate, part of the Walker Bay Fynbos Conservancy, milkwoods form part of a remarkable conservation story. Here, ancient groves persist in sheltered hollows and folds in the mountains – rare, enduring pockets of forest in a fynbos world.
Built for the Edge: Adaptations of a Survivor
The white milkwood is perfectly engineered for coastal life. Its thick, leathery leaves reduce water loss and resist the abrasive salt carried by sea spray. The wood is dense, the branches flexible—able to bend under the pressure of relentless wind rather than snap.
Beneath the sand, a deep taproot anchors the tree and draws moisture from hidden reserves far below the surface. Growth is slow, a deliberate strategy that conserves energy in the nutrient-poor soils of the coastal plain.
Yet much of the milkwood’s success happens underground. Its roots partner with mycorrhizal fungi, microscopic allies that extend the root network and help extract scarce nutrients such as nitrogen and phosphorus. When rainfall, sea mist, or decaying leaves briefly enrich the sandy soil, these fungi move fast—absorbing and transferring nutrients before they leach away.
Through these partnerships, the milkwood does more than survive. It engineers its surroundings, stabilising dunes, moderating wind and temperature, and creating shaded refuges where other plants and animals can thrive.
The Trees That Walk
Beneath the canopy of an old milkwood grove, one might see dozens of trunks—each twisted and aged, rising from the sand in close clusters. But appearances can deceive. Many of these “forests” are not large communities of trees, but a few individuals that have quietly persisted for millennia.
The secret lies in the milkwood’s ability to reproduce asexually. Through suckering, new shoots rise from the roots or base of the trunk. Through layering, a low branch bends to the ground, takes root, and begins life as a new stem while still attached to the parent. These processes produce genetically identical offspring—clones of the original tree.
Over centuries, as older stems die on one side and new ones establish on the other, the organism slowly shifts its position. The result is a forest that appears to “walk” through the landscape. Each trunk represents another chapter in a long, continuous life—proof of extraordinary endurance in a shifting coastal world.
A milkwood alive today may carry the exact DNA of a stem that stood in that spot thousands of years ago. What seems like many individuals may in fact be one ancient being – alive, resilient, and still moving.
Roots of Meaning: The Cultural Life of the Milkwood
Long before conservationists recognised its ecological value, the white milkwood held deep meaning for coastal communities. Among isiXhosa-speaking people, the tree—known as umThombothi—is revered as a symbol of strength, wisdom, and protection.
Its shade served as indawo yokuhlangana, a natural meeting place where elders gathered, stories were told, and decisions were made. The milkwood’s milky sap was seen as a sign of life and continuity, its steadfast presence a reminder of endurance through hardship.
In traditional belief, it is also umthi wookhokho—the tree of the ancestors—offering shelter to spirits as well as people. Cutting or harming such a tree was taboo, a breach not only of custom, but of respect for the living land.
Today, this reverence finds echo in modern law: the white milkwood is protected under South Africa’s National Forests Act, and may not be damaged, pruned, or removed without a permit. What was once sacred through story is now safeguarded by statute.
Lomond: Continuing the Tradition of Care
At Lomond, the connection between the milkwood and people continues. Beneath the same canopies where gatherings once took place, the estate’s The Milkwoods @ Lomond venue now hosts events such as long table lunch and wine tasting functions. Visitors often describe the setting as “otherworldly” – a natural cathedral of green light and silence.
Beyond its beauty, this place represents a philosophy of stewardship. As a member of the Walker Bay Fynbos Conservancy, Lomond helps protect more than 23,000 hectares of fynbos and forest habitat. Conservation at Lomond extends from alien vegetation clearing and wetland rehabilitation to the careful preservation of these ancient groves.
This work embodies ukulondoloza—the Xhosa concept of caring for what sustains life. By protecting the milkwoods and the ecosystems they support, Lomond continues a lineage of guardianship that stretches back generations.
Just as the milkwood clones itself through time, this tradition of respect and renewal also carries forward—rooted in the same soil, speaking the same quiet language of continuity.
The Living Legacy of the Agulhas Plain
The white milkwood is more than a tree. It is a living archive of endurance, ecology, and culture. Its roots hold the dunes; its shade shelters life; its form carries memory. Beneath its branches, the boundaries between past and present, science and story, human and wild begin to blur.
At Lomond, these trees are both heritage and teacher—a reminder that survival is not resistance, but relationship. They stand as the estate’s silent sentinels, walking slowly through centuries, holding the land together, and inviting us to remember that conservation is not only about protecting nature—it is about protecting connection.
Lomond are currently undertaking a reforestation project with one of the sites being the existing ancient Milkwood and White Stinkwood grove. With guidance from Platbos, pioneers in indigenous forestation, we have begun planting new milkwood trees. We have also built our own nursery and begun propagaton for future planting.
