Judy, thank you for the other aroid information. I have had similar "other aroid" experiences: I grow Pinellia pedatisecta here at my Olathe, KS, home. It is quite vigorous and very winter hardy. Every growing season I have numerous seedlings that germinate in the planting bed and in the nearby lawn. However, come the following spring, there are incredibly few seedlings that survive the winter. I think it is because our winters are so cold and dry for such shallow seedlings. I have had Sauromatum at my house, and at my 20 acre "play property" near Paola, KS, for the last 13 years. It has been reliably winter hardy until this last winter...it did not survive. We had a colder than normal winter. Also, in those 13 years, I have had no flowers at either property. The Sauromatum, and Arisaema dracontium, have been completely deer resistant at my Paola property. The Sauromatum at both locations has been slow to clump. The Green Dragon is slow to clump at my Paola property, but very readily clumps at home. I assume it is because of the better growing conditions at home. However, the deer do eat the leaf blades of Arisaema triphyllum at my Paola property and at my fishing cabin near Park Rapids, MN. I have one Jack-in-the-Pulpit at my house that has been in-ground for 13 years and is now three large, tall stems. I assume they clump with time and with no disturbance. I once tried Dracunculus vulgaris in-ground at my home. It lasted maybe two winters (no flowers) before disappearing. And last summer I tried a few Amorphophallus konjac in-ground. They grew amazingly well, but didn't emerge this year...I attribute that to our last winter or just to them not being winter hardy enough. I over winter all my aroids like these, which are grown in pots, in my garage. My garage is heated to about 40 F. They are brought indoors before the frost becomes too heavy or we have a freeze. If the foliage is still green, I allow it to die down in the garage. They are then stored on a shelf, but I do give them some minor water about twice during the winter. I don't know if the water is for my frame of mind or is actually doing some good to the plants. They are brought outdoors again once the chance of frost is basically over for the spring, or once they begin to grow. If they are growing early, I take them indoors at night if we have a chance of frost or freeze. My large Konjac flowers early; it is usually in bloom for Easter. It, too, goes in and out, especially for the first few days of "stink." Even that early in the year it attracts numerous flies and small beetles, but has never set seed as it is only the one genetic individual. The more unusual or tropical type of bulbous aroids I over winter in my house. They are treated the same as the ones that are over wintered in the garage, but I feel they need warmer dormant temperatures. Cheers from another rainy day in Olathe, KS! --Jerry Lehmann
