Wow, what an adventure - to garden on the other side of the world! Unfortunately, we don't have a hardiness map for Korea. But all is not lost! All it takes to find your "zone" and appropriate plant choices is a little research. Hardiness zone designations are based on average minimum winter temperatures, and are designed to guide you in choosing perennial plants based on their cold tolerance. There are other climatic factors (humidity, winds, persistent fog, maximum summer temps) that may bemore critical depending on their severity.

If you're choosing perennials and shrubs for your landscape, ask the weather service there for average minimum winter temps in your region. Then look at a USDA zone map and see how the reading fits into the zone designations. Once you have the hardiness info, talk with local gardeners, visit a botanical garden and peruse books about gardening in your region to help refine your choices, since those other cliamtic conditions I mentioned may limit what will succeed there.

If you're interested in annual flowers and vegetables, hardiness is seldom an issue, except at high elevations or extreme latitude. So long as you have 90 or so frost-free, mostly-sunny days, good soil and access to water, you can grow most any annuals Burpee has to offer (especially if you can start them indoors from seed for transplant later). Hope this helps!
