Hoya kerrii has thick, succulent, heart-shaped leaves and grows as a vine. This is a slow grower so don't expect it to take off any time soon.
The leaves are adapted to hold water so you don't need to water this plant too often but don't let it sit in dry soil, a good guide is to water when the top half of the soil is dry and not before.
This Hoya likes being pot-bound so don't repot it too soon.
It needs bright light and can tolerate regular household humidity but would be happy in a bright bathroom or kitchen.
