Boehmeria macrophylla, commonly known as Smallspike False Nettle, is a deciduous perennial herb native to tropical Africa and the western Indian Ocean. It can grow up to 3-6 feet (0.9-1.8 meters) in height and spreads 2-4 feet (0.6-1.2 meters) wide. The plant features large, heart-shaped leaves and produces inconspicuous yellow-green flowers in spike-like inflorescences during the winter and spring. The flowers are typically unisexual, with plants being either dioecious or monoecious, meaning individual plants may have either male or female flowers or both.

Smallspike False Nettle is valued for its lush foliage and ability to thrive in wet conditions, making it suitable for rain gardens, water features, and areas with poor drainage. It is also used for erosion control along stream banks. This species prefers consistently moist soil and can tolerate a range of light conditions, from full sun to partial shade. While it is not commonly afflicted by serious pests or diseases, it can spread aggressively in ideal conditions, potentially becoming invasive in some areas. Gardeners should be aware of its spreading habit and manage it accordingly to prevent unwanted naturalization.CC BY-SA 4.0
