Potato Bush vs. Vine

Potato vine (Solanum laxum) and potato bush (Solanum rantonnetii) belong to the identical family, which contains more than 1,400 species of plants worldwide. Both plants have been subtropical, native to South America and produce fragrant blooms. Even though these plants have many similarities, their forms are different. Pick the one best suited to your growing requirements and garden requirements.

Growing Requirements

Potato vine is hardy at U.S. Department of Agriculture plant hardiness zones 8b through 12. It grows in both full sun and partial shade and tolerates moderate drought once established. It tolerates ocean-side states, according to San Marcos Growers. Potato bush is hardy in USDA zones 9 through 11. This plant grows best in full sunlight and needs regular moisture, particularly in warm weather. Both plants have been deer-resistant.

Form

The potato vine is just a rambling evergreen vine that can grow to 30 feet in length. It has small, dark-green leaves and white flowers with yellow centres. The plant blossoms year in gentle climates, although it is most prolific in the spring. The potato bush includes a bush kind and can grow to 8 feet tall and wide. It has evergreen leaves and large purple flowers with yellow centres. The stems have a gentle, arching type.

Utilizes

Potato vine is an perfect plant for offering vertical interest in the garden. Bend it to a trellis or arbor, or let it scramble up a porch for afternoon shade. In warm, moist climates, the plant can become invasive. Cut it back each spring to control its development. Potato bush is just a showy plant for a combined bed or perennial border. Plant a few bushes as a hedge, spacing them at least 8 feet apart. Potato bush spreads quickly. Cut it back in the spring, as well.

Factors

Both potato bush and potato vine belong to the Solanum family, including tomatoes, peppers, and deadly nightshade. The plants produce small fruits in the autumn, which are typically poisonous, in accordance with Sunset magazine, based on the variety. Unless a plant tag indicates that the berries are edible, assume that they are poisonous and prevent them.
