Peruvian primrosewillow (Ludwigia peruviana) was introduced as an ornamental
because of the pretty flowers.
However, this member of the evening-primrose family is now a Category 1
invasive pest plant, according to the Florida Exotic Pest Plant Council.
Plants in this category “are altering native plant communities by displacing native
species, changing community structures or ecological functions, or hybridizing with
natives.” This determination is based “on the documented ecological damage caused.”
Also called Peruvian water-primrose, it is native to many parts of Central America,
Mexico, the Caribbean, and South America.
It thrives in and alongside swamps, lakes, ditches, marshes and canals.
A propensity to for m standing or floating monocultures -- floating islands -- can
threaten aquatic plants and animals by deoxygenating the water.
This long-lived multi-branched shrub can reach more than 12 feet high.
The dark-green alternate leaves have prominent veins and paler undersides, on
which the veins are very noticeable. Leaf shapes vary from lanceolate to elliptical to
Newer stems and leaves are often hairy.
Showy yellow flowers are borne singly, measure about two inches across, bloom
year ‘round, but last only a day. They have four (sometimes five) rounded petals and
four persistent sepals, the outer leaf-like structures surrounding the flower.
The plant bears an elongated four-angled reddish or brownish fruit.
This invaders spreads by seeds, suckers, or submerged stems via wind, birds, water
or even lawn or agricultural machinery.
Although this species provides nectar for some native butterflies, you’ll help them
more by replacing this invasive plant with native nectar sources such as the native
Mexican primrosewillow (Ludwigia octovalvis).

Fort Myers Named
Tree City USA
With a nickname like “City of
Palms,” it’s no surprise that Fort
Myers is a perennial recipient
of the Arbor Day Foundation’s Tree
City USA distinction. For the 25th
consecutive year, the foundation has
honored Fort Myers for its commitment
to effective urban forest management.
Fort Myers achieved Tree City USA
recognition by meeting the program’s
four requirements: A tree board or
department, a tree-care ordinance,
an Arbor Day observance and
proclamation, and an annual community
forestry budget of at least $2 per capita.
“Fort Myers believes in the value
of trees as part of the fabric of a
community,” said Richard Moulton,
interim director of public works at the
City of Fort Myers. “Last year, the city
began establishing a second generation
oak hammock at Shady Oaks Park,
which was opened 46 years ago. This
will ensure that the next generation of
citizens will enjoy the shade of oak trees
at this community facility.”
Fort Myers was the first city in
Southwest Florida to become a Tree City
USA, and has held the distinction for a
quarter century. The city grows many of
the trees currently being installed at city
“Tree City USA communities see
the impact an urban forest has in
a community first-hand,” said Dan
Lambe, president of the Arbor Day
Foundation. “Additionally, recognition
brings residents together and creates a
sense of community pride, whether it’s
through volunteer engagement or public
