Telegraphweed (Heterotheca grandiflora)

Some weeds like this one actually produce cute flowers.

Some weeds are just too cute to cut! That is the case for this telegraphweed. The flowers it produces are bright and yellow which can add a nice pop of color to any garden or roadside. This happens to be the only Heterotheca species found in Hawai'i so it is quite special. Although this plant is nice in appearance, it is known for being stink! Touching these plants can leave an unpleasant smell on your hands. That may be the biggest reason for this weeds prolonged life.
