Monstera Deliciosa may be one of the most popular houseplants in the world, but beyond the familiar Swiss Cheese leaves lies a realm of rare and highly coveted cultivars that few have ever seen in person. These extraordinary varieties stand out for their unique colors, unusual variegation, and sheer rarity—making them the crown jewels of any plant collection.

In this post, we’re diving into three of the most exclusive and eye-catching types: Monstera Mint Siam, Monstera Devil Monster, and Monstera Blue Mint. Whether you’re a serious collector or simply a curious plant lover, these rare beauties are sure to fascinate you.

Monstera Mint Siam

Monstera Mint Siam is an incredibly rare variegated cultivar known for its mint-green marbling on deep green leaves. Unlike the white variegation seen in Monstera Albo, the Mint Siam displays a softer, cooler tone—often a blend of light green, cream, and silvery mint hues.

Key features:

• Minty marbled variegation that looks almost airbrushed
• Irregular patterns—no two leaves are alike
• Slower growing due to unstable variegation
• Very limited availability; often sold via auction or rare plant dealers

Monstera Devil Monster

The Monstera Devil Monster is a mysterious and less-documented cultivar that has recently surfaced in collector communities. It’s most known for its dark, almost black-green foliage and highly unpredictable variegation, pale white marble variegation.

Key features:

• Deep green to near-black leaves with possible white marble variegation
• Bold fenestrations (leaf splits) that mature dramatically
• A haunting, gothic vibe that lives up to its name
• Extremely rare, often mislabeled or confused with other dark Monsteras

Monstera Blue Mint

Monstera Blue Mint is a highly experimental and cutting-edge cultivar, admired for its cool-toned, bluish-green foliage with silvery mint variegation. It’s not a naturally occurring mutation but rather a highly selective breeding result.

Key features:

• Subtle blue-green undertones with mint and silver streaks
• Very slow growing and sensitive to light conditions
• Unstable variegation that can revert or change dramatically
• Almost mythical in rarity—very few documented specimens

These rare Monstera Deliciosa varieties are more than just plants. But for those who care for them, plants can mean so much more. They carry stories, effort, patience, and sometimes even healing. Whether you’re a seasoned collector or a plant parent looking to learn more about rare cultivars, adding any one of these to your collection would be like finding a botanical treasure.

But beware: these beauties often come with a hefty price tag, long waitlists, and special care needs. Do your research, buy responsibly, and most importantly—enjoy the thrill of growing something truly extraordinary.
