Some houseplants thrive no matter what you do to ’em. My mother-in-law’s tongue seems to fall into that category. It’s an African perennial herb, Sansevieria trifasciata, and it has absolutely thrived under my regime of inattention. I toss it onto the porch in summer, toss it into the study in winter. I forget to water it, now and then I divide it, and generally it grows and grows and grows. It has bloomed for me a couple of times, and it is blooming now. The fragrance is lovely – floral, sweet, and light.
