Good news: you probably want to keep this

This is a native wildflower, not a weed. Butterfly weed is a monarch host plant and one of the best pollinator plants in North America — it cannot survive mowing, never invades a lawn, and almost nobody who scans it should remove it. It is listed here because people photograph it and ask what it is.

What Butterfly Weed looks like

Flat-topped clusters of small, brilliant orange flowers on stiff hairy stems, standing in a tidy knee-high clump in the driest, sunniest, thinnest bit of ground you own. Break a leaf: the sap runs clear and watery, not milky — this is the milkweed without milk — and the leaves spiral alternately up the stem rather than sitting in the opposite pairs almost every other milkweed has.

Best approach: Hand-pull or dig

Mark it with a stake in autumn: butterfly weed is the last perennial to break ground in spring, and every year people dig out established plants during spring cleanup thinking the ground is bare. An old clump resents disturbance and moves at roughly even odds, so sowing pods where you want them beats relocating the parent.

Spray in spring or fall when temperatures are 60–80°F and the weed is actively growing. Avoid summer heat — stressed grass takes collateral damage.

Non-chemical management

The first answer is to leave it: mow around it, or pull the mow line in a foot and let it stand at the bed edge. If it is out in mown turf you already have your answer, because it cannot survive repeated mowing and will fade on its own. Genuinely in the wrong place? Dig, never spray — take ten to twelve inches of intact taproot in early spring as shoots break ground, or in late autumn once dormant.

How to stop Butterfly Weed coming back

Nothing to prevent. If you simply do not want volunteers, snip the pods in late summer before they split, since seed is its only means of spread — no runners, no rhizomes, and seedlings take two to three years to flower.
