Sleepy Florida Hibiscus

The star of our field trip to the Indian River Lagoon Greenway on 8/11/2018 undoubtedly was the lovely lindenleaf rosemallow (Hibiscus furcellatus) pictured above.  Also known as sleepy hibiscus, this member of the mallow family, Malvaceae, is native to the southeast coast of Florida from […]

Weeds of Wednesday: Coffee Senna

The devil, often, is in the detail … When a new plant volunteered in our yard after Hurricane Irma, I did not look too hard at it and thought, happily, that privet senna (Senna ligustrina) had volunteered.  The Florida Plant Atlas calls it privet wild […]

Weeds Of Wednesday: East Indian walnut or lebbeck tree

On our field trip to the Captain Forster Hammock Preserve on 3/3/18, it was heartening to see that nearly all of the invasive East Indian walnut trees (Albizia lebbeck) had been cut down and treated with herbicide. This Florida Exotic Pest Plant Council Category #1 […]

Weeds of Wednesday: Siam weed?

Hurricane Irma coupled with the disturbance associated with the extensive professional invasive plant control work at the Oslo Riverfront Conservation Area (ORCA) has allowed jack-in-the bush (Chromolaena odorata) to display its weediness dramatically. This subtropical plant, a member of the daisy family, Asteraceae, is native to […]

Weeds of Wednesday: A New Name for Guineagrass

Guineagrass is shown above growing near the bike rack at the northwest “main” entrance to the Oslo Riverfront Conservation Area (ORCA). For awhile the politically correct name for this grass was giant panicum. Not anymore, though, since the botanical name of this grass has been […]

Weeds of Wednesday: Paragrass

Paragrass (Urcochola utica) was clogging the ditch on the south side of Oslo Road near the southeastern entrance to the Oslo Riverfront Conservation Area, until Indian River County recently cleaned the with and mowed the right-of-way. Common names for this plant include para grass, buffalo grass, California grass, Carib grass, […]

Weeds of Wednesday: Flowering Rosary Pea

Good Golly, its flowers are pretty. They stood out on our first post-hurricane IRMA group walk on 10-8-2017 at the Oslo Riverfront Conservation Area (ORCA). Pictured above are the flowers of rosary pea (Abrus precatorius), a Florida Exotic Pest Plant Council (FLEPPC) category #1 invasive […]

Weeds of Wednesday: Invasive Plants Intact after Irma

Wish that I could say that Hurricane Irma damaged the invasive pest plants at the Oslo Riverfront Conservation Area (ORCA) significantly. Yes, some Brazilian pepper (Schinus terebinthifolia) is scorched by salt and wind as are exposed oaks and even mangroves. Many leaves and small branches are […]

Weeds of Wednesday: Latex plant

Barbie Martz (Class of 2012) sent the photo above of a mystery fruit and vine that she took near Wabasso Beach. It is latexplant (Araujla odorata), also known as latex vine, strangler vine, and white milkweed vine. Technically, it is a liana, a tropical woody […]

Weeds of Wednesday: Bad, Bad Balsampear

Balsampear, balasm pear, wild balsam apple, bitter melon, bitter gourd, and bitter squash are some of the common names for Momordica charantia, an invasive pest plant that hails from the Old World tropics. After the Hurricanes Frances and Jeanne in 2004, this vine overtook the […]

Wednesday Weeds: Delectable but Dangerous

They are not ripe yet, but they soon will be. Strawberry guava (Psidium cattlelianum) fruits supposedly taste somewhat like strawberries. Another common name, Cattley guava, honors 19th Century English horticulturalist William Cattley, as does the species name, cattleianum. The genus name, Psidium, means pomegranate in Greek, and strawberry […]

Weeds of Wednesday: Worst of Worst

Old world climbing fern (Lygodium microphyllum) makes air potato (Dioscorea bulbifera) look docile.  Beware if you see a fern climbing in your yard, shown above along with air potato and cattley guava (Psidium littorale), yet another invasive pest plant. Like all ferns, old world climbing fern […]
