Podocarpus henkelii aka Falcate Yellowwood
Taxonomy ID: 1929
Podocarpus henkelii is an evergreen conifer, in the Podocarpaceae family. The RHS calls it falcate yellow-wood. It comes from eastern and southern Africa. Its range includes Tanzania, Malawi, Zimbabwe and South Africa. It grows in mountain rainforests, often on steep, rocky slopes. There, it reaches the forest canopy or rises above it. In the south, it also grows in coastal forests. Useful Tropical Plants cites the 2013 IUCN Red List. This lists the tree as Endangered. The site links its decline to forest loss and heavy harvests.
In gardens, the RHS gives a height of 13–26 feet [4–8 metres]. Its spread reaches about 8–13 feet [2.5–4 metres]. The RHS places many plants near 20 feet [6 metres]. Wild forest trees can reach 66–98 feet [20–30 metres]. The crown is dense and shaped like a cone. Garden plants may form tall shrubs or small trees. Long, narrow leaves hang down from the branches. They are glossy, dark green and shaped like willow leaves. Older trunks can form grooves and a spiral twist. Large trunks may reach about 3.3 feet [1 metre] across.
Wind moves pollen from one tree to the next. Male and female flowers grow on separate trees. Both sexes must grow nearby for fruit and seed. The sources give no flowering season for this species. Growth is slow, and poor sites slow it further. The RHS gives 10–20 years to reach full size. Useful Tropical Plants lists no known uses as food or medicine. It also lists no known hazards. This does not prove that every part is safe to eat.
Choose a sheltered spot with full sun and good drainage. Keep soil moist, and guard against cold, drying winds. The RHS accepts clay, chalk, loam and sand. It accepts a range of soil pH levels. Useful Tropical Plants favours deep, moist sand or loam. Trees can cope with some drought once they take root. Reports differ on how much cold they can bear. The RHS assigns H5, covering roughly 5–14°F [-15 to -10°C]. Useful Tropical Plants says they withstand only brief, light frosts. The RHS notes that trees do better in mild gardens.
Gardeners value its evergreen form and leaves that hang down. The RHS suggests courtyards, informal gardens, beds and patio pots. It needs no routine pruning. Reports note few pest or disease problems. Take semi-ripe cuttings in late summer to raise more plants. Builders and joiners use its wood, as do furniture makers. Wild trees supply local users and the timber trade.
Common names
Falcate Yellowwood, Henkel's Podo, Henkel's YellowwoodMore information about Falcate Yellowwood
How big does Falcate Yellowwood grow?
Henkel's yellowwood is a slow-growing tree that eventually reaches 20-30 metres in height with a trunk diameter exceeding 1 metre. In gardens and under cultivation it grows more slowly than in optimal natural conditions. The crown is dense and pyramidal, with long drooping leaves giving the tree an elegant, weeping appearance.
Where does Falcate Yellowwood come from?
Native to the moist inland and montane forests of KwaZulu-Natal and Eastern Cape, South Africa, with the largest natural concentrations between Mt Ayliff, Kokstad, and Harding. The species also occurs in Afromontane forests in Malawi, Tanzania, and Zimbabwe at elevations of 1,300-2,000 metres.
How often should you water Falcate Yellowwood?
Henkel's yellowwood thrives in moist conditions and grows best in high-rainfall areas with deep, moist soil. Established trees develop moderate drought tolerance, but consistent moisture produces better growth. Avoid waterlogged or permanently wet soils.
What soil does Falcate Yellowwood need?
Prefers deep, moist, sandy or loamy soil (light to medium texture). Organic-rich, slightly acidic to neutral soils are ideal. Intolerant of alkaline or waterlogged soils; benefits from added organic fertilizer.
What temperature does Falcate Yellowwood prefer?
Tolerates mild frost, surviving temperatures down to approximately -1°C to +4.4°C (USDA zones 9-10 as a rough guide). In its native habitat it grows at elevations of 1,300-2,000 metres with a mean annual temperature around 16.7°C. In cultivation it has been grown successfully in southern California, England, and Wales.
Does Falcate Yellowwood produce flowers?
Henkel's yellowwood is dioecious: male and female reproductive structures occur on separate individual trees. Male plants produce small pink pollen cones; female plants bear roundish olive-green seeds about 1.5-2 cm in diameter on a small fleshy receptacle. Wind pollination is the primary mechanism. Both a male and a female tree must be present for seed production.
How is Falcate Yellowwood pollinated?
The species is wind-pollinated and dioecious. Seed dispersal relies on birds, notably the Cape Parrot, which feeds on the seed kernels. Large old yellowwood trees are preferred nesting sites for this endangered parrot, creating an important ecological relationship between the tree and the bird.
How do you prune Falcate Yellowwood?
Henkel's yellowwood can be pruned to maintain a formal or desired shape, or left unpruned to develop its natural dense pyramidal crown. Pruning is best done lightly as the tree is slow-growing; heavy pruning will take many years to recover.
How do you propagate Falcate Yellowwood?
Propagate from fresh seed; remove the fleshy outer coating before sowing. Cold storage of seed before sowing improves results. Sow in moist, semi-shaded conditions; germination typically takes approximately two months. Both male and female seedlings will be produced, and sex is only apparent once the tree matures.
Can you grow Falcate Yellowwood outdoors?
Is Falcate Yellowwood edible?
The edibility of Podocarpus henkelii is not well documented, and no plant parts are formally listed as edible. For the closely related P. macrophyllus, the fleshy arils surrounding the seeds have been regarded as edible, but the seeds themselves are toxic and should not be consumed. Until species-specific data is available, treat all parts of P. henkelii as non-edible and exercise caution.
Does Falcate Yellowwood have medicinal uses?
Traditional uses across southern and eastern Africa include treatment of cholera, stomach diseases, rheumatism, cancer, canine distemper in dogs, and gall sickness in cattle. Laboratory research has confirmed that leaf extracts (particularly acetone and methanol fractions) contain biflavonoids with antimicrobial, antiviral, anti-inflammatory, and antioxidant activities. Antiviral studies demonstrated inhibition of canine distemper and lumpy skin disease virus replication by more than 75% at low concentrations.
What is Falcate Yellowwood used for?
The pale yellowish-brown timber is fine-grained and even-textured, historically prized for construction, carpentry, joinery, and furniture making. However, it has low natural durability and is susceptible to termite damage, which limits outdoor use without treatment. The tree is protected in South Africa, so commercial harvesting from wild populations is restricted.
What pests and diseases affect Falcate Yellowwood?
No significant pest or disease problems are specifically documented for Podocarpus henkelii. Related Podocarpus species are generally low-maintenance and resistant to most common garden pests. Established trees are tolerant of drought and salt; overwatering and waterlogged soils are the main cultural risk.
Why is my Falcate Yellowwood growing slowly?
Henkel's yellowwood is inherently a slow-growing species. In suboptimal conditions — poor soil, insufficient moisture, or shade — growth slows further. Organic fertilizer and adequate moisture are the most effective ways to encourage steady growth. Patience is essential; this is a long-lived tree that rewards multi-decade cultivation.
How do you care for Falcate Yellowwood through the seasons?
As an evergreen in a frost-hardy climate, Podocarpus henkelii requires minimal seasonal intervention. Ensure adequate moisture during dry periods, particularly when the tree is young. Fertilize with organic matter in spring to support the growing season. In cooler climates, protect young plants from hard frost until established.
What are the varieties of Falcate Yellowwood?
Henkel's yellowwood (P. henkelii) is distinguished from the real yellowwood (P. latifolius, South Africa's national tree) by its distinctively longer, drooping leaves. Several Podocarpus species occur in southern Africa, but P. henkelii is recognized by its slender lanceolate leaves 9-12 cm long and its pyramidal form.
