This 4.5" Hoya Karnosa Plant likes a bright east or west window.
Let the soil dry out between watering, the Hoya Karnosa is never very thirsty only when parched.
Water your Hoya with melted snow or rainwater. Bottled water works well too.
The plant you are purchasing may or may not be the one from the picture. All plants are grown in the same pot and look very similar.
