Where are the seeds or seedlings of Lysimachia hainanensis? I want to plant. I don't know if it's good or not. Planting methods and so on can be discussed.

There seem to be many, just around Haikou. I've seen a lot occasionally. You can ask, Hainan's climate is more suitable for planting, mainly depending on your management, and the benefits are not bad. The first two years may not be so good. After three years, a few hundred thousand dollars a year is no problem, and the rent in Hainan is not expensive.
