Hoya plants are tropical plants from eastern Asia and Australia. They form large vines with thick, dark green leaves. They are popular because of their ability to adapt to almost any environment. Since they require very little maintenance, even neglected hoyas can be nursed back to health. If you have a neglected hoya, bring it back to life with a couple of easy steps.
Hoyas that have been starved for water will have rounded leaves. When you water the plant, the leaves will unroll.
Putting hoyas in a south-facing location will make their leaves yellow.
