Sometime after I planted them out, I heard that cleome is fragrant. The promise of scent had me watering and weeding my three seedlings, awaiting a flower. This week, the most vigorous plant bloomed. I buried my face in the wispy flowers and inhaled. Quite puzzled, I sniffed again. There was no doubt about it, cleome smells like skunk!
The plants are fragrant indeed. They have a light, musky, animal odor. I would not recommend cutting a bouquet of cleome for the dining table, or anywhere else in the house. While the effect of one plant is mild, I can only imagine the stink that a sweep of cleome would make.
