Canna Flower Asymmetric. Flower lacks any plane of symmetry and cannot be divided into equal halves in any plane. The only fertile stamen comprises a one-theca anther and a petaloid appendage and represents the lowest stamen number in the order Zingiberales.
A flower is said to be asymmetric or irregular if it cannot be divided into two similar halves by any vertical plane passing through the centre as in Canna. The leaves are typically solid green but some cultivars have glaucose brownish maroon or even variegated leaves. Our Canna Asymmetric Flower Drop Earrings feature a whimsical cluster of white see-through flowers on long modern golden lines.
Afloweristrimerous tetramerous or pentamerous when the floral appendages are in multiple of 3 4 or 5 respectively.
The molecular mechanism for the asymmetric androecial petaloidy remains poorly understood. 20122020 Canna indica is a common ornamental plant with asymmetric flowers having colourful petaloid staminodes. 14012021 Natural occurrences of asymmetric stamen can also be found in some species yet the detailed structural patterning process of these stamen which in turn controls the symmetry of the whole flower is not well understood. The only fertile stamen comprises a one-theca anther and a petaloid appendage and represents the lowest stamen number in the order Zingiberales.
