Is Moonvine considered a recommended perennial bulb for Louisiana landscapes?

Moonvine, also known as Ipomoea alba, is actually not regarded as a recommended perennial bulb for Louisiana landscapes. This plant is a tropical vine that has a tendency to behave as an annual in many regions outside of its hardiness range. In Louisiana, where the climate can be humid and subtropical, Moonvine may thrive for one season, but it does not reliably return each year like true perennials do.

Perennial bulbs are plants that survive through the winter months and regrow each year from their underground storage structures. Moonvine, while beautiful with its white, fragrant flowers that bloom at night, does not fit this category due to its growth habits and lifecycle. Its classification more closely aligns with annuals or tender perennials that may require special care to survive colder months.

Understanding the specific growth requirements and hardiness zones for plants is essential in landscape design and gardening, particularly in climates like that of Louisiana. Knowing that Moonvine is not a perennial in this region serves as important knowledge for making informed choices about plant selections in landscape planning.
