A rare plant, endemic to Ullung Island off of Korea in the Sea of Japan, which as well as being an attractive umbellifer, apparently has leaves and young stems with a good flavour, rather like celery but with a bit of a bite, and which apparently are very nutritious. The young leaves and stems can produce the earliest possible harvestable garden crop in many cold climates, sometimes as early as mid March!
For best results, sow immediately onto a good soil-based compost. Cover the seeds with fine grit or compost to approximately their own depth. They can be sown at any time, and germination can sometimes be quicker if kept at 15 to 20 degrees C. We sow most seeds in an unheated greenhouse and wait for natural germination, as many seeds have built-in dormancy mechanisms, often waiting for natural spring germination, hence giving them a full season of growth.
Common name:Wild Korean Celery, Korean Pig Plant
