- Description
-
The common name of "fly poison" comes from what the plant can be used as: to kill flies (by grounding a mixture of some of the plant parts--mainly the bulb-- and adding sugar). However, this plant-- including the bulb-- is poisonous to not just flies but also humans and animals (usually livestock). The bulb of Amianthium muscitoxicum is very poisonous. This plant contains toxic alkaloids in all parts of the plant. The second part of the name (muscitoxicum) called the species means "flies" and "poison" (Latin meaning from muscae and toxicum). You can propagate this plant through root division or seeds (however, propagating through root division is easier).
Another common name 'Stagger Grass' is used due to the effect eating the plant has on cattle. After consuming, the cattle may stagger. It can also lead to the cattle's demise.
The plant looks similar to Xerophyllum asphodeloides, Xerophyllum tenax, hyacinths, and butterfly bush's flowers.
It can be found growing as a native plant in moist woods, especially oak forests, bogs, low pinelands, savannas, meadows, and sandhills. It does best when receiving a few hours of sun per day.
There are no specific insects, disease or other plant problems.
