The Story
Plant Bio
Matelea decipiens, commonly known as oldfield milkvine, is a herbaceous perennial vine native to the glades and open woodlands of the southeastern and south-central United States. The climbing stems arise from a thickened root crown each spring, trailing along the ground or twining up nearby vegetation to heights of up to ten feet.
The species is distinguished by its heart-shaped, opposite leaves covered in fine hairs and its clusters of star-shaped, deep brownish-purple to maroon flowers that bloom in late spring. These blossoms feature prominent white anther appendages and emit a subtle fragrance that attracts native bees, wasps, and butterflies.

Planting
How to Grow
- Select a planting site with full sun to partial shade and exceptionally well-drained, sandy or rocky soil.
- Install a sturdy trellis, stakes, or plant near a companion shrub to provide a climbing structure for the twining stems.
- Water moderately during the first growing season to establish the root system, then reduce watering to match natural rainfall.
- Apply a thin layer of organic leaf mold or compost around the base of the plant each spring to provide slow-release nutrients.
Pro Tip
Plant this vine in lean, rocky, or sandy soil with sharp drainage; rich, moisture-retentive garden soils trigger root rot and cause the plant to fail.
Keep It Thriving
Care Guide
Do
- Provide a climbing support such as a trellis or wire frame to keep the vine off the ground.
- Ensure the soil is sharply drained to prevent winter root rot.
- Wear gloves when handling the plant to avoid irritation from the milky sap.
Don't
- Do not plant in heavy, waterlogged clay soils.
- Do not over-fertilize, as excess nutrients produce weak, floppy growth.
- Do not prune into the crown during the active growing season.

Common Questions
Oldfield milkvine questions
What zones can Oldfield milkvine grow in?
Oldfield milkvine is hardy in USDA Zones 5–9. Inside that range it survives winter in the ground; outside it, grow it as an annual or a container plant you protect.
Is Oldfield milkvine deer resistant?
Not reliably. Deer may browse Oldfield milkvine, especially tender spring growth — plan on repellents or fencing where pressure is high.
When does Oldfield milkvine bloom?
Oldfield milkvine typically blooms in late spring through early summer. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.
Does Oldfield milkvine need full sun?
Oldfield milkvine does best in full sun to part shade. In hot climates, afternoon shade keeps blooms fresher longer.
Is Oldfield milkvine drought tolerant?
Yes — once established (usually after the first full season), Oldfield milkvine handles dry spells with minimal watering. Water deeply its first year to build the root system that makes that possible.
