Florida's Most Endangered Plants

A Polka-Dot Wasp Moth (Syntomeida epilais) and a Bumble Bee on Garberia (Garberia heterophylla).  Garberia is an old-growth Florida native shrub that is virtually extinct.  It is so rare that it has no common name.  It is currently on the list of Threatened and Endangered Plants of Florida.

This low shrub is native to Florida and attains a height of 4 to 8 feet. It is also known as Garberia fruticosa. Garberia has dull grayish, viscid foliage that is quite distinctive. The obovate leaves are alternately arranged on the stems and are held vertically. The showy, late season flowers appear in terminal corymbs of lavender pink heads and are followed by small inconspicuous fruits; the fruits are achenes. Flowers literally cover the plant. Garberia is an attractive plant useful for planting alone as a specimen or in groups for its colorful show in late summer and fall.

Garberia is an attractive plant useful for planting alone as a specimen or in groups for its colorful show in late summer and fall.
 The reasons for Garberia's endangered status is that it is native to the sand ridges and hills of central and northeast peninsular Florida.  Most of these ridges have been bulldozed for development.
 We've preserved a stand of these scarce plants at our lake house in east Central Florida and they have come into full bloom despite the harsh summer in which we received less than 1/10th of our normal rainfall.  Unfortunately there are few other stands remaining in our area and as the plant only blooms for a couple weeks in fall it is unlikely that pollination much less seed and offspring will occur.
 There is no impetus for conservation in Florida as the Governor's Office and both houses of the Legislature are controlled by pro-growth Republicans who in large part do not believe in conservation nor the science of climate change.
 The main focus of Florida's government for the past 6 years of Republican control has been economic development and expansion of exurbs at any cost.
 The reality of that expansion is that the things that were so special about Florida are being lost and replaced with concrete, suburbs, and generic corporate crap (strip malls) from the Atlantic to the Gulf and everywhere between.

 Marsh American-Aster grows to 9 feet (3 m) in Florida and are easily recognizable in Fall-Winter by their large clusters of showy blooms

Mexican motorists awoke to a shock as gasoline prices at the pump shot up by more than 20% in some corners of the country on the first day of 2017, sparking panic buying, street protests and even a call by one prominent lawmaker for a "peaceful revolution," in response to "gasolinazos," as Mexicans call hikes in the government-set gasoline price.  Currently the price is set at 15.99 pesos per liter in Mexico City (about $2.85 per gallon), though prices will vary across the country.
