As it is so difficult to find Japanese ‘Shiso’ Perilla where I live, I bought the seeds online and I have been trying to grow myself. Japanese ‘Shiso’ seeds were unsuccessful and I am trying again, but half-purple type perilla is growing so quickly and the leaves grow very large. The fragrant is not quite strong but they are growing amazingly well. Now there are too many leaves. What can I use them for? This is one way to use a lot of leaves.
