Wild Grape Tetrastigma voinierianum

Previously knows as Vitis voinieriana in honor of M. Voinier, who was a French veterinary surgeon.   In 1910, it was added to the genus Tetrastigma by Francois Gagnepain. 

The Chestnut vine is grown as a common houseplant that does well in a hanging basket.  In its native setting, they are found growing in subtropical and tropical regions, primarily, rain-forests.  This vigorous vine, that will climb on any available object, does not provide edible grapes.  Its is often used to cover a wall. Pruning as needed throughout the season.  

A location that includes bright, indirect sunlight is ideal.  Direct sunlight is discouraged.  Under the proper growing conditions, this vine can grow in excess of 12" per month.  

Growing as a houseplant will rarely produce flowers. If flowers do appear indoors, they will tend to be small and scentless.  In addition, a house does not have the humidity that the plant requires to perform as its best.  If the humidity is too low, the leaves can droop and the plants appearance can suffer.  Temperatures below 50 degrees can also cause the foliage to blacken and die.  Yellowing leaves can indicate that the plant needs to be fertilized.  Increase frequency of fertilization in lieu of increasing the strength of your solution.  

The thick fuzzy green leaves are palmately compound.  Young stems are hairy.  It can be propagated using semi-ripe stem cuttings, ensuring to provide heat, humidity, and well drained soil.  When repotting, use a potting soil that provides good drainage, and mix with perlite, small gravel or sand to provide aeration and good drainage.

As fall approaches, decrease watering and stop fertilizing.  Pruning can be accomplished during the dormant season, fall through mid-February,  Avoid pruning once the plant begins actively growing, as this can cause damage to the plant.  If necessary, repotting should also be completed during the dormant months.

Insects, Diseases, and Other Plant Problems:  Watch for red spider mite, mealy bugs, scale insects, aphids and white fly.  Allow the soil to become nearly dry before watering, then water thoroughly.  Insure proper drainage after watering to prevent root rot.

Growing in Hawaii, which provide optimum conditions for this plant will cause it to grow in an invasive manner.
