Weeds of Wednesday: Goldenrod?

Goldenrod (Solidago sp.) gets a bad rap. The pollen of goldenrod is too large to be a human allergen, but goldenrod often blooms at the same time as ragweed (Ambrosia sp.), the real culprit. Nonetheless, many people consider goldenrod to be a weed. Pollinators flock […]

Weeds of Wednesday: Bad hair day or not?

Botany Lesson #1: Heterostyly

Dr. George Rogers, Botany Department Chair at Palm Beach State College, led a marvelous botany walk/talk on Saturday, November 18, for volunteers for the Oslo Riverfront Conservation Area (ORCA).  After a wonderful whirlwind “tour” of botany basics, we headed out in to the field, where […]

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 […]

Swamp Fern has a New Name

The first plant that Sam Chancellor (Class of 2010) mentioned in his wonderful presentation, A Gentle Introduction to Plant Names, on Saturday, November 4 for a group of twelve veteran volunteers was swamp fern, Blechnum serrulatum, pronounced BLECK-num ser-you-LAY-tum (or see-roo-LAH-tum). Sam also mentioned that […]

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, […]

Onion Orchid?

Common plant names are, well, common and sometimes even crazy. They are not standardized. Anyone can “assign” a common name, and often the same common name is used for different plants, especially in different regions. Somehow, Florida butterfly orchid or just butterfly orchid has come […]

Blooming 2X

The simpsons stopper (Myrcianthes fragrans) in the Oslo Riverfront Conservation Area (ORCA) parking lot is full of flowers — even more flowers than when it bloomed in the spring. Tropical plants sometimes will bloom a second time, unlike temperate plants which have a “set” bloom […]

Weeds of Wednesday: Tropical Milk-Weed?

Growing in the Oslo Riverfront Conservation Area (ORCA) parking lot amongst wild coffee (Psychotria nervosa) and last’s week’s Wednesday “weed”, beggarticks (Bidens alba), is what some folks call tropical milkweed (Asclepias curassavica). Other common names include scarlet milkweed, Mexican milkweed, bloodflower, and silkweed. This plant definitely […]

Sea beans at ORCA?

On our first post-Irma walk at the Oslo Riverfront Conservation Area on 10/8/2017, Judith Fillipich (Class of 2016) pointed out the sea bean pictured above. Yes, it is a coconut. Only 1% of all seeds float, and they are called either sea bean or drift […]
