Hoya carnosa 'Grey Ghost' is a unique Hoya variety known for its silvery-grey leaves with minimal green. Its ghostly look comes from dense silvery speckles. It produces clusters of star-shaped flowers, ranging from near-white to dark pink.

How to care for your Hoya -

Water: Less is more when it comes to watering; we like to wait until the leaves pucker slightly.

Light: This Hoya grows best in very bright light. Southern exposure is best, but it can adapt to east or west locations in front of a window.

Humidity: They like high humidity and would be perfect for a bathroom or kitchen.

Temperature: Average room temperature is fine.
