Not an aroid but still a beautiful plant nonetheless! We have a slight obsession with Hoyas. As they mature they vine downward. Unlike most hoyas, they bloom single flowers rather than a cluster!
Hoyas love bright indirect and semi direct sun and this helps them achieve faster growth and flower more frequently. Water when the soil is near dry which may roughly be every 10-14 days. A good indicator for when to water Hoyas is if the leaves feel a little limp. They do great as mounts or potted plants in a coarse airy soil.
