What is a perennial grown as an annual? It’s a perennial plant that, in your hardiness zone, won’t survive the winter. It is often possible to protect these plants by insulation, or to bring them in for the cold season to prevent them from dying. Some plants are grown as annuals for productivity reasons.
A few examples

Pelargonium, or annual geranium, is actually a perennial plant that is not frost-resistant. Plants are usually bought back each year, but they can also be brought in for the winter and replanted. This is a much more economical option, as pelargonium seedlings are difficult to grow and hard to find.
Tomatoes also belong to this group. However, we generally don’t bother bringing the plants in, since they are much less productive in the second year. What’s more, they are often large by late autumn. It’s better to start new seedlings in spring.

Can I save my non-hardy perennials?
If there’s an interest in protecting plants, tisanji will generally suggest tasks in the autumn to give you the chance to save your plants. As always, these tasks are only suggestions: it’s up to you to decide what you want to do.
What happens when the garden is replanted?
tisanji, depending on your hardiness zone, checks whether the plant is a perennial or a perennial grown as an annual. If the system determines that it’s a perennial grown as an annual, it will ask you at the garden renewal for the next year what you’ve done with the plant. You’ll need to define the desired reproduction strategy, and you’ll also have the option of defining it as “in situ” if you’ve protected it, or “transplant” if you’ve brought it indoors.
