Long-lived plants, which are called perennials, can keep growing for three or more years. Perennial flowers include Japanese roses, periwinkles, and coleus. Perennial herbs include mint, basil, and Indian borage. Perennial vegetables include Brazilian spinach, Malabar spinach, and sweet potatoes.
Although perennial plants are typically low-maintenance, they can grow wild and look “leggy” with an accumulation of dead leaves and thick, untidy stalks over time. So how can we keep our perennial plants looking their best after a few seasons’ growth?
