Bougainvillea, commonly called paper flower, is a vigorous tropical vine known for its colorful bracts that surround its small flowers. It thrives in full sun and performs best in warm climates with well-drained soil. Once established, bougainvillea is highly drought tolerant and requires relatively little water. Too much moisture or fertilizer can reduce flowering and encourage excessive leafy growth. This plant is commonly trained on trellises, fences, walls, and arbors where its cascading growth creates dramatic displays. Bougainvillea blooms repeatedly throughout the growing season in favorable conditions and provides vibrant color in landscapes across warm regions. With proper sunlight, drainage, and occasional pruning, it becomes a spectacular focal point that adds tropical beauty and long-lasting visual interest.

Bougainvillea is rarely grown from seed because germination can be inconsistent and seedlings may not resemble the parent plant. Most plants are propagated from cuttings to preserve desirable traits and flowering characteristics. If starting from seed, sow them in a well-draining seed-starting mix and lightly cover them with soil. Keep the medium consistently moist and place containers in a warm location with bright light. Germination may take several weeks and can be unpredictable. Seedlings should be transplanted carefully once they are large enough to handle, as young roots can be sensitive to disturbance.

Plant bougainvillea in full sun and well-drained soil. Dig a hole slightly wider than the root ball and plant at the same depth it was growing previously. Water thoroughly after planting, then allow the soil to dry somewhat between waterings. Bougainvillea can also be grown in large containers with excellent drainage. Avoid disturbing roots during planting, as the plant can be sensitive to transplant shock. Proper placement in a sunny location encourages maximum flowering and vigorous growth.

Bougainvillea performs best with moderate feeding and should not be overfertilized. Incorporating compost before planting provides a healthy nutritional foundation while improving soil quality. A fertilizer formulated for flowering plants can be applied during the growing season to encourage bloom production and strong growth. Avoid excessive nitrogen, which often leads to abundant foliage and significantly fewer flowers. Container-grown plants may benefit from regular but light feeding throughout the growing season because nutrients are depleted more quickly. Proper nutrition supports colorful bracts, vigorous growth, and repeat flowering while helping maintain the plant's ornamental value in landscape settings.

Bougainvillea is only winter hardy in warm climates where temperatures remain above freezing. In regions that experience frost, container-grown plants should be moved indoors or into protected areas before temperatures drop. Outdoor plants in marginal climates benefit from mulch around the root zone to help insulate roots from cold weather. Frost-damaged growth can be pruned once temperatures warm and new growth appears in spring. Proper winter protection helps preserve plant health and encourages strong flowering when warmer weather returns.

Pruning helps maintain shape and encourages repeat blooming throughout the growing season. Light pruning can be performed regularly to control growth and remove damaged, dead, or overcrowded branches. More extensive pruning is best done after a major flowering cycle has finished. Bougainvillea blooms on new growth, so strategic trimming often results in additional flowers and improved branching. Wear gloves when pruning because stems commonly have thorns. Regular maintenance helps create a fuller plant with improved flowering performance while preventing excessive growth on walls, fences, trellises, and other landscape structures.
