How to identify Curcuma (Curcuma)
Curcuma exhibits a tropical presence with considerable size variation, ranging from 2 feet (60 cm) to towering over 7 feet (2.1 meters). Resembling Canna plants, curcuma features sizeable foliage. The distinctiveness of curcuma is marked by its unique pine cone-like flowers, which can precedently emerge before or after the foliage, varying according to its species. The shape and sequence of flower and leaf emergence are notable traits for recognition.
Lifespan: Perennial
Leaf Type: Deciduous
Distinct pine cone-like flowers, emerging before or after foliage.
Large leaves, lanceolate to oblong, 18-40 inches (45-100 cm) long.
Vibrant tubular flowers, 2-3 inches (5-7.5 cm) long in dense spikes.
Atypical nonviable fruit, small and ovoid, around 0.2 inches (5 mm).
Varied flower colors, including white, pink, purple, and yellow.
The leaves of curcuma are large, smooth, and lanceolate to oblong in shape, with entire margins. They typically measure between 18 to 40 inches (45 to 100 cm) long and 5 to 6 inches (12 to 15 cm) wide. Depending on the species, the leaves can be solid green, variegated, or feature a central red blotch. These leaves have a Canna-like appearance and are characterized by their substantial size and smooth texture.
The flowers of curcuma are vibrant and diverse, often likened to 'technicolor pinecones.' Their colors range depending on the species or cultivar and can be whites, pinks, purples, or yellows. The flower spikes may appear on pseudo stems or directly from the rhizome. Blooms can precede foliage emergence or follow it, dependent on species. Each flower is tubular, around 2-3 inches (5-7.5 cm) long, arranged in dense, showy spikes that can reach up to 3 feet (91 cm) in height.
The fruit of curcuma is notably atypical, as this species rarely produces seeds and when it does, they are generally nonviable. If encountered, the fruit presents as small and ovoid, measuring up to about 0.2 inches (5 mm) in length. They posses a brown hue, with a texture that can be described as slightly rough. These particular fruit characteristics contribute to their distinctive nature, although they are not commonly observed due to the plant's reproductive traits.
