Texas Canna (Canna glauca)
In the late summer of 2007 a friend/co-naturalist brought me seeds of this from a population on the west end of Galveston Island. After owning and living on the property for eight years he noticed a ring of yellow flowers around a now filled playa lake on his few acres.
He couldn't positively I.D. the plant as anything but a canna - but there's a good reason. The plant proved to be the very uncommon/rare and - certainly rarely collected Canna glauca. The plant has blue green leaves 4" to 8" wide and 12" to 30" long. Height is dependent on water conditions but varies from 2-1/2' to 3' in low water to 8' in shade with water. The flowers are a bright yellow tubes of 1-1/2" to 2" across petals in large orbicular masses. Both the leaves and the flowers are quite ornamental. The only reason this plant is not a common ornamental is its rarity.
Once established the rhizomes are both very drought tolerant (the plant simply retreats underground) and capable of freezing solid (personal experience). A must for any water garden/feature or tropically themed garden. Ready now!
