Frost Tender or Heat Tender. The basic definition of a tender plant is a perennial plant that will not survive the winter outdoors because it is sensitive to frost, but some plants are also labeled as heat tender.ost plants classified as tender do not thrive in cold temperatures, while those classified as hardy can survive wintry conditions, although the lowest temperature these plants can handle varies from plant to plant.
Some of our most useful plants in the summer garden are tender perennials. Many of them provide abundant color for a long period of time but unfortunately they die when cold weather comes. Examples are impatiens, coleus, petunia, and the common geranium (Pelargonium).ender perennials can be brought indoors in areas where winters are too cold for them. Geraniums, coleus, impatiens, and wax begonia winter well indoors and can be put back outside when temperatures warm up. They make nice container plants so bringing them indoors can be a plus.
