Swamp milkweed

Swamp milkweed

Swamp milkweed (Asclepias perennis) blooms in late spring through early fall and attracts many pollinators. It is a larval host plant for Monarch, Queen and Soldier butterflies.

Velvetleaf milkweed

Velvetleaf milkweed

Velvetleaf milkweed (Asclepias tomentosa) is a robust wildflower found in sandy upland habitats across the Southeastern Coastal Plain.

Largeflower milkweed

Largeflower milkweed

Largeflower milkweed (Asclepias connivens) is a perennial wildflower found throughout much of Florida. Its conspicuous flowers appear in late spring through summer in moist pine flatwoods, savannahs and bogs.

Fewflower milkweed

Fewflower milkweed

Fewflower milkweed (Asclepias lanceolata) is a delicate wildflower found in swamps and moist to wet pinelands and prairies throughout Florida. Its stunning orange flowers typically bloom late spring through fall.

Longleaf milkweed

Longleaf milkweed

Longleaf milkweed (Aslcepias longifolia) typically blooms in spring. It is a larval host for Monarch and Queen butterflies, and an important nectar source for bees and wasps.

Carolina milkweed

Carolina milkweed

With its narrow leaves and fine stems, Carolina milkweed (Asclepias cinerea) can get lost among the wiregrass with which it typically grows.

Florida milkweed

Florida milkweed

Florida milkweed (Asclepias feayi) is a dainty endemic at home in the sandhills and scrubby flatwoods of Central and South Florida. It emerges from winter dormancy in spring and typically blooms mid-summer.

Queen butterfly

Queen butterfly

In the same genus as Monarchs, Queen butterflies share many characteristics with their royal cousins. Queens and Monarchs are similar in appearance, rely on milkweed as a host plant and carry a toxin from milkweed in their bodies into adulthood.

Effect of Systemic Use for Commercial Nursery Propagation of Asclepias currasavica on Monarch Larvae

People who buy milkweed plants (most commonly Tropical milkweed [Asclepias curassavica]) from big box stores such as Lowes and Home Depot to feed monarch larvae frequently report that their larvae often die after feeding on the purchased plants. This is likely due to the plants being treated with topical or systemic insecticides. However, detailed information concerning the exact chemicals used and their potential impact on monarch larval mortality is poorly understood. This study sought to provide information on insecticides and larval mortality.
