Tucked seamlessly into the Scott Entrance Garden is a blooming Alcantarea imperialis ‘Volcano Mist’. This endangered plant blooms once in ten years and then dies. Drop by the Scott Arboretum this month to experience this rare occurrence.
These massive beauties can approach 8 feet in diameter and have up to a 3-foot tall flower stalk.
Alcantarea imperialis is part of a large family of tropical plants called Bromeliaceae, of which approximately one-third are endangered in the wild largely due to habitat loss and overharvesting for the retail market. Fortunately, some nurseries have started producing bromeliads from seeds or pups in an effort to save the family and bring it back from endangerment.
This particular A. imperialis was bought at the 2011 Unusual Tropical and Annual Sale and was later gifted back to the Arboretum after it grew too large for the owners to care for it properly. This past winter, the cup at the center of the plant, which typically holds water, was empty. Within a few days, the beginning of a flower spike was evident. The A. imperialis was planted in the Scott Entrance Garden in the early spring and will hopefully bloom for the rest of the summer.
Unfortunately, after the A. imperialis blooms, it will slowly start to die. The Scott Arboretum has taken steps by collecting pups from the blooming plant to continue this cultivar. In ten years time, there quite possibly will be another flowering bromeliad that was collected from this one, with just as much elegance and magnificence.
