Wednesday's Wildflower:Spanish Needle
Spanish Needle, Bidens Alba

Biden's alba, all photos by Donna Bollenbach
Nothing attracts more butterflies and
bees than a simple white flower called Bidens
alba. Also called Romerillo, Beggar’s Tick, Spanish Needle or Monkey’s Lice,
this Florida native wildflower is the
third most reliable source of nectar for pollinators in our state. There would
be many starving bees and butterflies if not for the Bidens family of flowers. More
so, Bidens alba and its sister plant,
Bidens pilosa, are both edible and have
medicinal value. Yet, many gardeners have a love/hate relationship the
plant, and some even consider it a pesky weed. Why?
The word Bidens means two-toothed, which describes the needle-like seeds that flowers in this family produce in enormous amounts. If you walk through a patch of Bidens that have gone to seed you come out looking and feeling that you were attacked by an army of little black needles, and good luck getting them out of your clothes. The “hitchhiker” seeds are easily spread by people, animals, wind and water, so it grows everywhere and anywhere, and once established, it is hard to get rid of.
But, if you love bees and butterflies, you need
to learn to love Bidens Alba. While
not a neat and tidy plant, it is can be very showy at its peak. The pretty
white and yellow daisy-like flowers bloom throughout spring, summer and fall in
Florida. It becomes quite weedy as it
ages, but if allowed to grow in a sunny area along a fence line, or in the back
of your garden and out of the way of any
foot traffic, it will pose less of
a problem for you when it goes to seed. What small discomfort you may feel by
the prickly seeds in your shoes and socks, you will be rewarded tenfold by the
colorful pollinators that you will attract to your yard.
most Florida climates it Bidens alba blooms nearly year round. They like sun, but will tolerate some shade. They are also very drought tolerant. The plants may die after the
first frost, but will come back quickly when the weather turns warm.A single plant can produce 3000-6000 seeds,
so if you don’t want them to spread you need to pull up or mow the plants before they
go to seed, or, you can eat them…The fresh or dried leaves of Bidens alba are edible. Peggy Sias Lantz, author of Florida’s Guide to Edible Wild Plants, recommends that you pick the youngest leaves and sprouts and “cook them in a few changes of water to get rid of the bitterness.” She also writes that if used sparingly, the leaves and flowers can also be tossed into a raw salad.
Bidens alba: Weed or wildflower?
It is all in the eyes of the beholder, and the butterflies.
Austrailian Pine fruits Australian pines seem to be everywhere in the coastal regions in the bottom half of Florida. Their name is deceiving because, while they are native to Australia, they aren't pines or even conifers. They are flowering trees with separate male and female flowers, and what look like needles are really green twiglets with close-set circles of tiny leaves that drop at the first sign of a drought. In the photo to the right, the light-colored lines are where leaves where once attached. Most of the photosynthesis takes place in the twiglets. There are three species of Australian pine ( Casuarina spp ) that have been imported into Florida for various purposes. They were widely planted to soak up the "swamps" in Florida, stabilize canals, and hold beaches. Unfortunately for Florida's ecosystems, the "pines" accomplished all this and more--like seeding prolifically, growing five feet or more per year, producing dense shade, and emitting
by Bob Silverman Blanketflower, Galliardia pulchella You don’t have to travel far to see one of the hundreds of native flowers that make Florida stand out. They’re nature’s roadside attractions, and many can make for colorful additions to your yard. Consider these natural wonders: Beautyberry, Callicarpa americana - this shrub dazzles with its clumps of purple fruit that will draw birds to your yard. Black-eyed Susans, Rudbeckia spp. - with a brown center surrounded by petals of yellow, golden, orange, or red petals, is perfect for attracting butterflies to your garden. Firebush, Hamelia patens var. patens - with its bright red flowers, can serve as a beacon for hummingbirds, butterflies, and songbirds (which like to feed on its berries). Tickseed, Coreopsis spp. - our state wildflower, sometimes called Coreopsis, comes in 12 species native to Florida. You’ll find all of them in the northern part of the state, but South Florida is limited to Leavenworth’s tickseed, Co
Man-in-the-ground ( Ipomoea microdactyla ), fantastically beautiful morning glory for southernmost Florida. A post by Roger L. Hammer Most everyone is familiar with morning-glories in the genus Ipomoea, and certainly everyone reading this has even eaten Ipomoea batatas, the common sweet potato. The Morning-Glory Family (Convolvulaceae) is well-represented in Florida, with 67 species in fourteen genera. Of those, twenty-four species are naturalized exotics, and four species are endemic to Florida, found nowhere else. The genus Ipomoea is the largest in the family, with twenty-five species and one naturally-occurring hybrid of two native species. Exactly half of the species (13) in Florida are native. Only two species are rare enough to be listed as endangered by the state of Florida, and these are the rockland morning-glory ( Ipomoea tenuissima ) and man-in-the-ground ( Ipomoea microdactyla ). Both are on the northern extreme of their natural range in Florida, and both are re
