Bougainvillea is a genus of vine-like shrubs native to South America. These vines are typically thorny (although there are thornless varieties) and range in size from 20 to 30 feet tall with an equal spread to tiny dwarfs that reach heights of 3 to 6 feet. These vines produce a spectacular show of color periodically through the year, but the showy blooms aren’t true flowers.
What appears to be flower petals are really colored bracts (much like the colored bracts of poinsettias) that surround three tiny flowers in the center.
Bract color ranges from shades of pink and purple to yellow, orange and white.
They are hardy in USDA plant hardiness zones 9 through 11 and must be grown in containers in cooler regions.
Bougainvillea can be categorized by size making it easier to choose the appropriate variety for your landscape. Generally they are labeled as dwarf, semi-dwarf and giant bougainvillea.
Dwarf Bougainvillea
Dwarf bougainvillea are ideal for small spaces or containers and typically reach a height and spread of 3 to 5 feet. They are easy to maintain and may be marketed as mini bougainvillea. Some can be pruned to more of a shrub than and ambling vine. If you are looking for a bougainvillea for containers or to add to a small landscape, consider one of these lovely dwarf bougainvilleas.

Semi-Dwarf Bougainvillea
Semi dwarf bougainvillea are ideal for locations with moderate amounts of space. They typically are well suited for growing in the soil as they may be too large for containers. If you are looking for a medium-sized bougainvillea for your landscape, consider one of these semi-dwarf varieties.

It is hardy in USDA plant hardiness zones 10 and 11.
‘Miss Alice’
‘Miss Alice’ produces large flowering bracts on a semi-dwarf, compact shrub. Foliage is medium green providing a nice contrast to the showy white blooms. This variety is considered thornless, although it may produce a few thorns. It blooms all summer and tolerates rain and high humidity. It reaches heights of 3 to 6 feet with an equal spread. It prefers full sun for 5 hours a day and thrives in USDA plant hardiness zones 9 through 11.
Giant or Full-sized Bougainvillea
Giant or full-sized bougainvillea add color and interest to the landscape, but these massive vines need plenty of room to grow. If you are looking for a giant or full-sized bougainvillea for your yard, consider these varieties.

Tips for Choosing a Bougainvillea
When choosing a bougainvillea for your landscape determine the amount of room you have for growing first, then choose one that will fit within the confines of your garden or landscape. Because there is no definitive guideline to determine if a bougainvillea is classified as dwarf, semi-dwarf or giant, you may find some discrepancy in labeling. Always read the label carefully to determine the size of the bougainvillea at maturity. Likewise, although most bougainvillea are hardy in USDA plant hardiness zones 9 through 11, there may be some exceptions.
If you are unsure if the variety you are interested in growing will do well in your location, talk to the nursery attendant. Observing which varieties do well for neighbors and in community gardens will also give you a heads-up on which variety ir right for you.
