NEXT TO CANNAS, which are about the easiest non-hardy bulbs or bulb-like plants to carry over year to year carefree in the cellar, I’d have to say that Eucomis bicolor, the pineapple lily (Zones 7 or 8 to 10), is winning me over for its similarly cooperative nature and long season of showing off. I enjoyed the potful that a friend gave me so much that this spring I ordered a dozen bulbs, and put three or four in each of several 12-inch containers. From the first purple-spotted leaves and stems to the crazy flowerheads, above, a winner. How to grow, and overwinter, Eucomis in pots.
