MoBOT is on a quest to save lots of the endangered agave, and it’s now within the midst of a concerted effort to try this. As Senior Horticulturist Jared Chauncey defined on Friday’s St. Louis on the Air, every of its agaves will bloom simply as soon as earlier than it dies. When it does, it’s time for scientists to spring into motion, guaranteeing that the seeds are pollinated and might reproduce.
MoBOT has been ready for its two agaves for many years now. However final month, the employees seen one of many vegetation was flowering.
It was laborious to overlook.
“There was a spiky rosette, and once they flower, they ship out a big shoot from the center,” Chauncey mentioned. “And whereas the plant is barely a couple of foot tall, this flower spike is now over 6 toes tall.”
Chauncey mentioned the vegetation are sometimes pollinated by hummingbirds or fruit bats, however on the botanical backyard, it’s a special story.
“We’re hand-pollinating it — we take the anthers of the pollen and pollinate it onto the feminine flower components, and it’ll hopefully pollinate and we are going to get seed,” Chauncey mentioned. “After which we are able to use the seed to develop to maintain the genetics of this plant within the assortment.”
Chauncey takes care of the arid, Mediterranean and subtropical vegetation at MoBOT. He mentioned one of many agaves has been alive for the reason that Nineteen Seventies and one other for the reason that ‘80s, suggesting that they might be slower to bloom (and die) attributable to their location in a greenhouse.
Chauncey mentioned the second plant is even older than the primary and can probably flower in a number of years. He steered the flowering Agave pelona had a number of extra months to stay.
“They typically begin to slowly decline after they flower. After which, as they undergo the ripening course of, they will decline additional,” Chauncey defined. “They take a bit longer to die if they really set seed, however then as soon as they set seed, every little thing is completed, they will be on their final leg, after which they will form of simply peter out.” In St. Louis, it’s as much as the scientists to verify their seeds take root.
