Could there be an error in the listing?

The sun exposure is set to shade. Having
lived in New Mexico for many years, I don't
quite recall much shade, but do remember
plenty of gourds in the full sun.

Native Americans also used the crushed gourds to put around other plants to deter insects.

San Antonio, Tx.
In my area we call this plant just "wild gourd". It can be found from Mexico to Missouri and Nebraska. The flowers are monoecious, that is, individual flowers are either male or female with both sexes being found on the same plant. The plant is self-fertile. When the seeds are spouting, a toxic substance is produced by their embryos and there are reports that the root is poisonous. It produces small round gourds that are green with vertical off white stripes. When the fruit is ripe, it turns a yellowish color.

Many native North American tribes used and still use wild gourd as a medicine. The mashed plant has been used as a poultice to treat skin sores and ulcers and the stems and leaves have been employed as a laxative. To remove stains from clothing, the fruit is sliced and simmered in water to obtain a soap substitute. The dried gourds having a thick, tough skin were used as rattles and carved to make spoons and ladles.
