The invention discloses application of feverfew siegesbeckia herb in remediation of soil contaminated with the heavy metal cadmium, which is realized through planting siegesbeckia herb in soil contaminated with the heavy metal cadmium. The siegesbeckia herb has an excellent property of accumulating the heavy metal cadmium, can absorb and accumulate the heavy metal cadmium, and transfer most of the heavy metal cadmium above the ground in order to realize remediation of soil contaminated with the heavy metal cadmium through being planted in the soil. The invention not only has the characteristics of low cost and strong operability because the siegesbeckia herb needs no special treatment during the growing process but also can increase the remediation effect of heavy metal in soil of unit area because the siegesbeckia herb has a large quantity, and develops a new plant resource applied for plant remediation of soil contaminated with heavy metal.
