The Spanish Needle plants (Bidens pilosa) in our hill are growing up again, and a few hundreds of them growing together resemble a Spanish Needle carpet. The plants are lush and green with little or no signs of pest infestation. All parts of the Spanish Needle plant can be used, and the young leaves can be eaten raw or steamed with other vegetables. However when taken in high doses, Spanish Needle can irritate the bladder and kidney.
Spanish Needle plants are attractive to bees, butterflies, and some birds. In some places they are known as Needle Grass, Shepherd’s Needles, and Butterfly Needles.
