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.
Perennials This time the Latin 'perennis' means 'many years'. Sometimes called 'herbaceous perennials', which simply means they 'disappear' in winter.In fact, they die back to a rootstock where next year's shoots are protected and then magically grow back each spring.ut 'bedding' is usually taken to mean those half-hardy annuals or half-hardy perennials planted out to make a splash of colour in the summer. For example; petunias, begonias, pelargoniums and calceolarias. Find out more about taking delphinium cuttings and growing chrysanthemums and fuchsias on the main site.
