Calendula officinalis , the pot marigold , ruddles , common marigold or Scotch marigold , [2] is a flowering plant in the daisy family Asteraceae. It is probably native to southern Europe , though its long history of cultivation makes its precise origin unknown, and it may possibly be of garden origin. It is also widely naturalised farther north in Europe as far as southern England and elsewhere in warm temperate regions of the world. The Latin specific epithet officinalis refers to the plant's medical and herbal uses. The disc florets are tubular and hermaphrodite , and generally of a more intense orange-yellow colour than the female, tridentate, peripheral ray florets.

The present paper aims to perform a screening of native plants growing in Kettara mine-Marrakech Southern Morocco for its phytoremediation. Plants and soil samples were collected and analyzed for Pb, Zn, Cu and Cd concentrations at several sites in the mine. The results showed that the soil in the vicinity of Kettara mine is deficient in major elements and contain toxic levels of metals.

Spontaneously growing native plants were botanically identified and then classified into 21 species and 14 families. Lagreze-Fossat, Lamarckia aurea L. Moench, Calendula algeriensis Boiss. This was confirmed by the transfer factors generally higher than 1.

Using the most common criteria to classify the hyperaccumulator plants, these species can be classified as new accumulator plants of many heavy metals and be potentially used as remediation tools of metal-contaminated sites.
