Garlic Vine (Mansoa hymenaea)
Garlic Vine, Mansoa hymenaea, is a tropical perennial vine prized for its vivid lavender-to-purple, tubular blooms and its unmistakable garlic-like aroma when the leaves are brushed or crushed.
In Florida planting zone 9, it’s most often trained on fences, arbors, and trellises where it can climb and spill outward, creating a dense, flowering screen. When it’s happiest, it rewards you with long stretches of bloom and steady pollinator activity.
For best performance, give it support to climb, room for airflow, and occasional pruning to keep growth tidy and encourage fresh flowering shoots.

Companion Planting
Companion planting with Garlic Vine can help create a layered, tropical look while also increasing nectar and habitat diversity for pollinators. Choose companions with similar light and moisture needs, and give climbing plants adequate space so they don’t smother each other.
Bougainvillea (Bougainvillea spp.)
Benefits: Intense color contrast and long-season interest; thrives in sun and handles heat well.
Use:
- Plant near sturdy structures so both can be trained cleanly.
- Prune regularly to prevent one vine from overtaking the other.
Golden Dewdrop (Duranta erecta)
Benefits: Adds shrub structure and supports pollinators; bright blooms complement purple vines.
Use:
- Place as a backdrop shrub near trellises or fences.
- Keep away from play/pet areas if fruiting is a concern.
Hibiscus (Hibiscus rosa-sinensis)
Benefits: Bold flowers add height and focal points beneath a climbing vine canopy.
Use:
- Plant at the base or nearby to create a layered, tropical bed.
- Maintain airflow between shrub and vine for healthier foliage.
Jasmine (Jasminum spp.)
Benefits: Adds fragrance and additional bloom cycles, boosting pollinator traffic.
Use:
- Train on separate sections of a pergola or fence for tidy growth.
- Prune to prevent tangling and shading.
Gardenia (Gardenia jasminoides)
Benefits: Glossy evergreen foliage and fragrant white blooms contrast beautifully with purple flowers.
Use:
- Plant near the vine base as a “foundation” shrub layer.
- Mulch to maintain moisture and reduce root stress in heat.
Passionflower (Passiflora spp.)
Benefits: Adds unique flowers and supports butterflies; increases biodiversity.
Use:
- Only co-plant if you have ample space and strong supports.
- Train intentionally so one vine doesn’t overwhelm the other.
