Description: This tropical-looking plant will produce an exotic flower in late Spring usually 3 years after grown from seed. The first flower is usually male, although it is more likely to be female as it gets older. A female flower, when pollinated will form a pod of red berries in the Fall. It’s an imposing plant emerging in late June with a parasol of approximately 12 leaflets tailing off at the tips in long tendrils giving it the appearance of a 3 1/2’ tall palm tree. Under the leaf looms a purple and green pitcher-like spathe with a hood ending in a long dangling thread. Looks like a hooded cobra with a long tongue. Easy to grow in zones 5 thru 9 and highly deer resistant, it will produce many offset bulbs around the main bulb to create a clump of plants. The seeds inside the berries are very easy to germinate and will produce more plants. Zone 5a to 8b. The germination rate of the seeds I sell should be close to 100%, because I store them in plastic bags in the refrigerator after removing them from their berry coating and drying them. I test the seeds occasionally to verify this germination rate and rarely keep them for a year. When you receive them, you should keep them in their plastic bag refrigerated until you plant them. A week before planting, soak them in warm water with a drop of dishwashing soap added. Do this for a week, occasionally changing the water. This softens the hard seed coat and rinses off any berry residue that can inhibit germination. I generally plant seeds in plastic containers with covers or pots with plastic wrap over the top. I usually use a seed mix that I press the seeds into and then cover seeds with a fine layer of gravel, chicken grit or even a thin layer of potting mix to cover seeds. I set them under lights or near a sunny window at room temperature and it takes about 3 to 6 weeks for seeds to germinate. I may keep the seedling in this container for a year or 2 before trying to transplant into other pots. Don't be alarmed if seedlings go dormant early the first year and die down. I usually keep seedling pots in a cool greenhouse above freezing and barely water them during the winter until they sprout back up. All of the Arisaemas I list are grown in zone 6a in New York State. After they have reached a certain size, about half that will be for sale are moved to plastic bags containing slightly moist perlite and stored in a refrigerator. We do this as we can't dig them up from the frozen ground to sell, yet they are cold cycled into being ready to sprout new leaves and flowers in the spring. If you decide to dig them up and store them this way. you should watch them to see they stay in good condition. Check occasionally as certain Arisaemas like A. ringens and A. triphyllum may actually start growing in the fridge. They need to be potted up at this point, if too cold to plant outside. Monitor dryness as well. You want to see a couple of beads of condensation inside bag, but bulbs should not appear wet. Do not put in freezer! Good drainage is important if planted in a pot, I recommend a 50:50 mix of potting soil and perlite. Not too fussy about soil type or drainage outside, but don't plant in a soggy location or extremely dry location Great shade plant. but will take a half day of sun.
