It is a flowering plant found primarily in meadows and grasslands and sometimes in open woodlands.

It grows 40 to 80 cm high with leaves 10 to 16 cm long which have between 8 and 20 pairs of narrow leaflets.

A. falcatus has been cultivated experimentally for dryland grazing in the US and possibly in France, and was proposed as a forage crop in the USSR.

[3] However, it is one of the milkweeds containing a poisonous glycoside identified as miserotoxin.
