We grow many plants in our gardens and homes introduced from other parts of the world. We try to stretch the boundaries of climates with the tedious process of planting annuals each year because they cannot survive our winters. We dig Dahlia and other tender, summer-blooming bulbs and mother them for the winter to plant them again the next late spring.
I am always delighted to see tender plants and houseplants growing in their native climate. During a recent visit to southern Africa, I was amazed at the huge Sansevieria plants (Mother-in-law’s tongue) growing at will alongside the road. Now I admit that this houseplant is a toughie, but still it cannot be perennialized here.
