Hoya Sp. Aff. Burtoniae and Hoya Bilobata both have olive green foliage. This, of course, can vary depending upon the light exposure the plant gets from its environment. Hoya Sp. Aff. Burtoniae can have a reddish cast to the leaves in higher light and a dark ring around the edges of each leaf.
Water regularly with room-temperature water, spring through summer. Let the top layer of soil dry between watering. In the fall and winter growth naturally slows down and they won't use as much water. Water sparingly during fall and winter, give them just enough that the soil doesn't dry out completely.
Espoma’s Orchid! liquid fertilizer is perfect for Hoya. The dosing cap eliminates measuring and gives exactly the right amount every time. Feed once a month from spring through fall.
Grow in well-drained, moderately fertile soil in a sheltered, sunny site. Protect in winter in cold areas.
Prune in spring before vigorous growth begins. The stems with no leaves are called spurs and shouldn’t be removed. Flowers are produced on the same spurs year after year. Hoya are vining plants that will happily cascade from a shelf or window sill. Conversely, they are often trained onto trellises that are either vertical or circular, giving the impression of a more robust plant.
