Our Top Rare Indoor Plants

1. Anthurium Clarinervium

Velvety drama + bold veins = instant showstopper

With heart-shaped leaves and high-contrast veins, the Anthurium Clarinervium looks like it stepped out of a jungle photoshoot. Native to Mexico, this beauty likes things warm, a little humid, and bright — but never direct sun.

Care Tips:

• Light: Bright, filtered sunlight. Avoid harsh rays.
• Water: Keep soil lightly moist, but never soggy. Let the top inch dry out.
• Humidity: Loves 60–80%. A pebble tray or small humidifier is a great gift.

Note: Anthuriums are toxic to pets and curious kiddos, so keep this one up high and out of reach.

2. Monstera Obliqua (Peru Form)

Rare, delicate, and full of holes (on purpose!)

The Monstera Obliqua is legendary for its dramatic fenestrations — those iconic Swiss cheese-like holes. But don’t let the fragile look fool you; it’s a determined little grower if you give it the right care.

Care Tips:

• Light: Bright, indirect. Filtered sun works best.
• Water: Keep evenly moist, but let the top 2 inches dry slightly before watering again.
• Humidity: Needs high humidity (think 70%+). A sealed glass case or cabinet works wonders.

Handle with care — the leaves are extremely delicate and tear easily. Bonus: it’s a climber, so moss poles are welcome.

3. Hoya Kerrii Variegata

Succulent hearts with creamy borders = love at first sight

Known as the “Sweetheart Plant,” the Hoya Kerrii is a slow but steady grower with thick, heart-shaped leaves edged in creamy variegation. She’s a bit of a diva about sunlight but otherwise low-key.

Care Tips:

• Light: Bright, indirect. Can handle morning sun.
• Water: Let dry out between waterings (around 10–14 days).
• Humidity: Average indoor humidity is fine, but she appreciates a mist now and then.

Keep an eye on her variegation — if it starts to fade, she might need a sunnier seat.

4. String of Dolphins (Senecio Peregrinus)

Yes, those leaves look like tiny dolphins!

This playful succulent is a favorite in hanging pots, where it spills over the edge in waves of aquatic charm. But don’t let the cute fool you — String of Dolphins is picky about light and water.

Care Tips:

• Light: Needs at least 6 hours of bright light daily. Filtered sunlight is best.
• Water: Water deeply, but only once soil is completely dry. About every 2–3 weeks.
• Humidity: Prefers drier air — over-humid conditions can cause rot.

Caution: Like most Senecios, it’s toxic to pets. Hang it high!

5. Philodendron McDowell

Big, bold leaves + trailing vibes = instant jungle

With oversized heart-shaped leaves and distinct white veins, the Philodendron McDowell is a favorite among collectors. While it looks dramatic, it’s surprisingly easygoing — as long as it gets what it wants.

Care Tips:

• Light: Indirect and consistent. Too much sun = leaf burn.
• Water: Let the top layer of soil dry out, but don’t let the pot go bone dry.
• Humidity: 50–70% is the sweet spot. It’ll thank you with lush growth.

Bonus: Give it a wide pot and let it sprawl — it loves to stretch!

6. Peperomia

From the ripple-leaved Watermelon to the dainty Raindrop and Frost, rare Peperomias are small in size but big on charm. Their low-maintenance nature makes them ideal for shelves, desktops, and tight spaces.

Care Tips:

• Light: Bright, indirect light helps colors pop. Too dark? Growth slows and leaves dull.
• Water: Allow the top inch of soil to dry out. They hate soggy roots.
• Humidity: Average room humidity is fine, but they’ll perk up with 40–50%.
• Bonus: These beauties love snug pots. No rush to repot — they thrive a little root-bound.
