Mountain Love in the Mist: A Mysterious Puerto Rican Passion Vine
If you’ve stumbled across the name mountain love in the mist while researching native Puerto Rican plants, you’ve discovered one of the more enigmatic members of the passion vine family. Passiflora tulae, as it’s scientifically known, is a perennial herb that calls the beautiful island of Puerto Rico home.





Where Does Mountain Love in the Mist Come From?
This native Puerto Rican species has a very limited geographic range, found only in Puerto Rico. As a true island endemic, mountain love in the mist represents part of the unique botanical heritage that makes Caribbean flora so special.
What Kind of Plant Is It?
Unlike the woody passion vines you might be familiar with, mountain love in the mist is classified as a forb or herb. This means it’s a vascular plant that lacks significant woody tissue above ground. Think of it as the more delicate cousin in the passion vine family tree – it dies back to ground level but returns each year from its perennial root system.
Should You Grow Mountain Love in the Mist?
Here’s where things get a bit tricky, and we need to have an honest conversation. While this plant sounds absolutely enchanting (and that common name is certainly romantic!), there’s very little documented information available about cultivating Passiflora tulae. This lack of information often indicates that a plant is:
- Extremely rare in the wild
- Difficult to cultivate
- Not yet studied extensively by horticulturists
- Possibly extinct or nearly extinct
Growing Conditions and Care
Based on its wetland status as Facultative Upland, mountain love in the mist typically prefers non-wetland conditions but can tolerate some moisture. This suggests it might appreciate well-draining soil that doesn’t stay soggy, which is fairly typical for many passion vine relatives.
Unfortunately, specific details about preferred growing conditions, USDA hardiness zones, and cultivation requirements aren’t well-documented for this particular species.
A Word of Caution for Responsible Gardeners
If you’re interested in growing mountain love in the mist, proceed with extreme caution. The scarcity of cultivation information suggests this may be a rare species that should only be grown from responsibly and legally sourced material. Never collect plants from the wild, especially in Puerto Rico where endemic species face numerous conservation challenges.
Instead, consider these alternatives that can give you a taste of passion vine beauty in your garden:
- Passiflora suberosa (corky-stem passion vine) – another Puerto Rican native
- Passiflora foetida (wild passion vine) – more widely available
- Other native Puerto Rican vines suited to your specific growing conditions
The Bottom Line
While mountain love in the mist has an absolutely enchanting name and represents the unique botanical heritage of Puerto Rico, it’s not a plant for the casual gardener. If you’re determined to learn more, connect with botanical gardens specializing in Caribbean flora, native plant societies in Puerto Rico, or conservation organizations working to preserve the island’s endemic species.
Sometimes the most responsible way to appreciate a rare plant is to support its conservation in the wild rather than trying to grow it in our gardens. Mountain love in the mist might just be one of those special plants that’s best admired from afar while we work to protect its natural habitat.
