How Do You Plant Arisaema?
Arisaema are diverse perennials with fun nicknames like “Jack in the pulpit” and “cobra lily.” These distinctive plants grow from seeds and from tubers, and require specific care and attention during dormancy in order to survive. Order seeds from a breeder, or gather your own. For most species, you will need to have both a male and female plant in order to get seeds. Some varieties are unisex, while others change sexes during their lifetime. Clean the seeds. Place ripe, seeded fruit into a plastic sandwich bag. (The fruit is toxic and can cause numbness or severe pain.) Squish the fruit several times, then pour the mush into a cup. Add water, rinse and strain a few times until the seeds are clean. Immediately bury one cleaned seed in a 1/4-inch depression in clean potting soil, and water thoroughly. The seed will sprout in four to six weeks, and grow for two to four months before going dormant. Dormant plants appear dead, but they’re not. Expect flowers in two to four years. Order tube
