Philodendron Mamei – Silver Cloud

Philodendron Mamei is a tropical beauty that was first discovered in the rainforests of Ecuador. Also known as ‘Silver Cloud’, it has wide, heart-shaped leaves that feature stunning silver variegation. Philodendron Mamei is tolerant and easy to care for – a great low-maintenance plant for beginners and seasoned enthusiasts alike. Even better, it is a fantastic air purifier, making it a practical addition to any space.

Silver Cloud features a unique and distinctive ruffled stem that sets it apart from other Philodendron species. It will happily climb up a coir pole, or if left to its own devices will creep across the ground maintaining its upright profile. Like most Philodendrons, it is happiest in moderate to bright indirect sunlight, but it will also do well in low light. Philodendron Mamei particularly enjoys moist, humid conditions – therefore, give your plant an occasional misting to keep it looking and feeling loved.

Often considered one of the rarer Philodendron varieties, Mamei is a newcomer to the New Zealand market. As such, its maximum height here in optimal conditions is still to be discovered. Leaves can grow as long as 45cm according to some sources. The name Philodendron is derived from the Greek phileo (meaning ‘to love’) and dendron (‘tree’).

Philodendron Mamei Plant Care


Philodendron Mamei is an indoor pot plant that does well in most conditions, however, it does not respond well to significant dips in temperature. Keep your Silver Cloud in a room that stays between 15-25 degrees to optimise condition and growth, and position it away from doorways to avoid sudden draughts.


With a preference for bright, indirect light, Philodendron Mamei will also do well in low light conditions, making it a versatile houseplant. Make sure you rotate your plant to ensure it’s getting an even amount of light but keep it out of direct sunlight which could do severe damage. Given time, Silver Cloud will communicate its needs – too much light and leaves will appear scorched; too little, and leaves will become darker, losing their silver streaks.


Philodendron Mamei prefers moist conditions, but getting the balance right is key. Water when the top part of the soil has dried out entirely – it will not appreciate becoming waterlogged. Make sure the pot is draining well to prevent damage to the roots. You can water less over the winter months. Treat your Silver Cloud with regular misting and it will respond well.


Philodendron Mamei is unlikely to need repotting for a couple of years, so pick a beautiful pot to accentuate its position in your space. You might consider sizing up as it grows and develops though, as it will not enjoy becoming root-bound. Optimise photosynthesis by wiping down the leaves with a damp cloth to remove accumulated dust. 


We recommend using a balanced fertiliser on monthly basis throughout the growing season to ensure Silver Cloud stays in top shape.


As with other Philodendron species, Mamei is considered toxic and should be placed well out of reach of children and pets. Symptoms may include swelling of the mouth and esophagus.


Silver Cloud will do well in most standard commercial potting soils. A neutral to acidic pH is important, which is standard for most store-bought soils.


When the roots appear to have filled the bottom of the pot it is time to upgrade the pot size

Potential Problems

Root Rot:

Root Rot is caused by overwatering or sodden soil, so keep a watchful eye on the moisture levels in your soil. Watering once a week should be sufficient. When repotting, use a quality mix that promotes good drainage. 

Brown Leaf Tips:

Often means the plant is not getting enough light, or that conditions are too dry. Try moving your plant to an east or west-facing window and misting regularly.

Leaf Yellowing/Drooping:

Can be caused by too much light, insufficient fertilisation, overwatering, or pests. Check the leaves for intruders and follow care recommendations to isolate and solve the problem.


Not typically prone to pests or diseases, Philodendrons may still be affected. Spraying diluted neem oil on the leaves can get rid of unwanted intruders.
