Latexplant: A Fragrant Climbing Vine for Warm Climate Gardens

If you’re looking for a fast-growing vine with sweetly scented flowers, you might have come across the latexplant (Morrenia odorata). This perennial climbing vine has been making its way into Florida gardens, though it’s not originally from North America. Let’s explore what this plant has to offer and whether it might be right for your garden.

What is Latexplant?

Latexplant is a herbaceous perennial vine that belongs to the forb family – meaning it’s a flowering plant without significant woody tissue. True to its name, this plant produces a milky latex sap when cut or damaged. The vine features heart-shaped leaves and produces clusters of small, white, intensely fragrant flowers that can perfume an entire garden area.

Originally from South America, particularly Argentina, Uruguay, and southern Brazil, this non-native species has established itself in Florida, where it reproduces naturally without human intervention.

Why Consider (or Not Consider) Latexplant?

Reasons you might want to grow it:

  • Incredibly fragrant flowers that bloom repeatedly
  • Fast-growing vine perfect for quickly covering fences or trellises
  • Attracts butterflies and other pollinators
  • Drought tolerant once established
  • Thrives in warm climates

Reasons you might want to think twice:

  • Non-native species that may compete with local flora
  • Can be an aggressive grower that requires regular pruning
  • Limited to warm climate zones (USDA zones 9-11)
  • May not provide the same ecological benefits as native alternatives

Growing Conditions and Care

If you decide to grow latexplant, here’s what it needs to thrive:

Light and Location: This vine performs best in full sun to partial shade. It needs a sturdy support structure like a trellis, fence, or arbor to climb.

Soil Requirements: Well-draining soil is essential. Latexplant is quite adaptable to different soil types but doesn’t tolerate waterlogged conditions.

Climate Needs: Hardy in USDA zones 9-11, this plant thrives in warm, subtropical climates. In cooler areas, it can be grown in containers and brought indoors during winter.

Planting and Care Tips

  • Plant in spring after the last frost date
  • Provide immediate support for the vine to climb
  • Water regularly during establishment, then reduce frequency as the plant becomes drought tolerant
  • Prune regularly to control growth and prevent it from overwhelming other plants
  • Be prepared for vigorous growth – this vine can cover large areas quickly
  • Handle with care due to the milky sap, which may cause skin irritation in sensitive individuals

Consider Native Alternatives

While latexplant can be an attractive addition to warm climate gardens, consider exploring native flowering vines that provide similar benefits while supporting local ecosystems. Native alternatives like coral honeysuckle (Lonicera sempervirens) or crossvine (Bignonia capreolata) offer beautiful flowers and better support for local wildlife.

The Bottom Line

Latexplant can be a stunning addition to gardens in warm climates, offering rapid coverage and delightfully fragrant flowers. However, as a non-native species, it’s worth weighing its benefits against the potential ecological advantages of choosing native alternatives. If you do choose to grow it, be prepared to manage its vigorous growth and enjoy the sweet fragrance it brings to your outdoor space.
