Solanum laxum (White Potato Vine) is a beautiful vine or creeper that is native to Brazil, Ecuador and Paraguay. This vigorous climber grows quickly and easily, reaching up to 15 feet or more in height. It has a showy display of white flowers that bloom for much of the year, sometimes with a pleasant mild fragrance. Solanum laxum does best in full sun or semi-shade and prefers low to moderate water once established.

The flowers come in shades of white and off-white, as well as lavender, blue and even purple hues. It is an excellent choice for gardeners looking to attract butterflies and hummingbirds, as these insects love its fragrance.

When grown outdoors, Solanum laxum is a good choice for USDA zones 8-10. In cooler areas, it can grown in pots and brought inside during the winter. When grown in a container, make sure to use a potting mix that has good drainage, and fertilize during the growing season. Provide good air circulation to reduce the risk of fungal diseases, and give it plenty of sun for best results.
