Asclepias curassavica

S & J Nursery’s Guide to Growing

Scarlet Milkweed / Butterfly Weed / Asclepias
currasavica

for the Northeast Florida Landscape


(Asclepias curassavica)

Scarlet Milkweed is one of the easiest milkweed varieties to grow for our Northeast Florida landcsapes and
provides an abundance of food for the larva of the Monarch and Queen butterfly as well as blooms for butterflies
and other pollinators from early spring until fall.

A WORD ABOUT  PESTICIDES ON MILKWEEDS

Grown as a larval plant for the Monarch, Queen and Soldier Butterfly , our butterfly plants are grown here on
site from seed, cuttings, or divisions and not treated with herbicides or pesticides. Making them
available without added chemical toxins to the newly hatched caterpillars as a food source also puts them on the
menu for other critters like Milkweed bugs and Aphids. In reality, you can’t have one without the other. Treating
them in any way for the removal of the aphids etc. would also harm caterpillars as well as remove or kill
the unhatched eggs laid on the plants by visiting Butterflies. We like to leave them be and allow natures
system of checks and balances to kick in to control pest populations.  See Pesticides on Butterfly Plants for more information
