Egger’s Morning-Glory: A Rare Caribbean Climbing Beauty

If you’re looking for a unique climbing vine with tropical flair, Egger’s morning-glory (Ipomoea eggersii) might just be the hidden gem you’ve been searching for. This lesser-known member of the morning glory family brings a touch of Caribbean authenticity to gardens in the warmest climates.

What Makes Egger’s Morning-Glory Special?

Egger’s morning-glory is a perennial climbing vine that’s native exclusively to the U.S. Virgin Islands. Also known by its synonym Exogonium eggersii, this plant represents a true piece of Caribbean botanical heritage. As a twining climber, it develops relatively long stems that can be either woody or herbaceous, making it a versatile addition to vertical garden spaces.

Where Does It Grow Naturally?

This morning glory calls the Virgin Islands home, where it has adapted to the warm, tropical climate and unique growing conditions of these Caribbean islands. Its limited natural range makes it a special choice for gardeners who want to cultivate truly native plants in appropriate climates.

Garden Design and Landscape Use

As a climbing vine, Egger’s morning-glory works beautifully when you need to:

  • Cover trellises, arbors, or pergolas
  • Add vertical interest to garden walls or fences
  • Create natural privacy screens
  • Bring authentic Caribbean character to tropical landscape designs

This vine is best suited for tropical and subtropical gardens where the climate can support its natural growing requirements.

Growing Conditions and Care

While specific growing information for Egger’s morning-glory is limited due to its rarity in cultivation, we can make educated recommendations based on its native habitat:

  • Climate: USDA hardiness zones 10-11 (tropical to subtropical)
  • Temperature: Prefers consistently warm temperatures year-round
  • Sunlight: Likely thrives in full sun to partial shade, typical of morning glories
  • Support: Needs sturdy structures for climbing due to potentially woody stems

Pollinator and Wildlife Benefits

Like other morning glories, Egger’s morning-glory likely provides valuable nectar for pollinators including butterflies, bees, and possibly hummingbirds. The flowers probably open in the morning hours, offering an important food source when many other blooms are closed.

Should You Plant Egger’s Morning-Glory?

Consider planting it if:

  • You live in a tropical climate (zones 10-11)
  • You’re creating an authentic Caribbean or tropical garden
  • You need a climbing vine for vertical spaces
  • You enjoy growing unique, lesser-known native plants

It might not be right for you if:

  • You live in cooler climates where it won’t survive outdoors
  • You prefer low-maintenance plants with readily available growing information
  • You need immediate availability from local nurseries

Finding and Growing This Rare Beauty

Due to its limited native range and rarity in cultivation, finding Egger’s morning-glory may require some detective work. If you do locate this plant, ensure it comes from reputable, responsibly sourced material. Consider contacting botanical gardens in tropical regions or specialty native plant societies for guidance.

When growing any rare native plant, it’s important to support conservation efforts and never collect from wild populations. Instead, work with nurseries and organizations that propagate native plants responsibly.

While we may not have all the growing details figured out yet, Egger’s morning-glory represents an opportunity to preserve and celebrate Caribbean botanical heritage—one garden at a time.
