Featured Plant

Agave desmettiana ‘Variegata’

This agave is a charismatic and eye catching succulent with curvaceous, lance shaped variegated foliage. However, what is really captivating is the recent production of a 2.5 meter (8.2 feet) tall flower spike awash with alluring lime green flowers. The buds first began forming towards the end of November 2018 but in late January, opened to begin a stunning floral display which will lasted for a short number of weeks.

Though this is a spectacular event, it also spells the end for this stunning plant. Agave desmettiana ‘Variegata’ is monocarpic, meaning that it flowers only once in its lifetime and then will die. The production of seeds causes changes induced by chemicals that act as hormones redirecting resources from the roots and leaves to the production of seeds. This enormous bust of energy happens typically at about 10 years of age and ultimately leads to the plants death. This plant does however, leave behind a legacy. Numerous offsets or pups are produced around the base of the plant which can be potted up to create new plants.
