hardiness of Sauromatum

Thanks Diana, I and a number of others grow it easily in USDA zone 6 (NW Arkansas, in my case), and it's survived overnight lows of -20 F (-28 C) with no problem. Even the smallest offsets have no trouble with the cold. I think I remember Panayoti Kelaidis in Denver telling me that it was hardy there (yes, "hardy in Denver" again), and I recall that some I sent Ellen Hornig years ago survived at least their first winter in upstate New York. Since Wilbert insists on sinking this into Typhonium, and Typhonium has also been a popular topic lately, this gives me a perfect segue to hardiness in Typhoniums in general. Besides venosum and giganteum - which produces marvelously tropical-looking leaves when happy outdoors - what are the coldest growing and hardiest members of the genus?

From: Douglas Ewing dewing at u.washington.edu> on 2000.07.30 at 15:31:41(5180) Here is my $o2. on Sauromatum: It is perfectly hardy where I live north of Seattle (USDA Zone 7). More to the point, it is a weed. I planted tubers in my garden a dozen years ago for a researcher who studies thermogenic plants. We were successful in getting a crop, although we decided to stick to producing the research material in containers, as was done previously. Ever since, I have been battling this plant in my garden. It is extremely difficult to get rid of. I would classify it with Arum maculatum, as potentially invasive, noxious weeds.

From: Ellen Hornig hornig at Oswego.EDU> on 2000.07.30 at 15:33:23(5185) Since Steve Marak mentioned sending me sauromatums (typhoniums) years ago, I thought I'd better check in with my own report. The tubers you sent me, Steve, eventually expired in the garden, where I had planted them in what was probably a much too heavy soil. As best I remember, I had more in pots; and concluding that they would not be hardy, I dumped whatever remained into the compost heap. That compost heap was eventually spread across an area that became a new garden, and last year I started noticing small sauromatums there. This year there are at least three good-sized ones (one bloomed) and several little ones. We are somewhat colder here in upstate NY than Steve is in Arkansas (though technically only a half-zone colder, we can have long spells where highs linger in the teens (Fahrenheit) and lows are down to -10F or so, but these are usually at times when we have good snow cover). In general, zone 6 herbaceous plants are pretty safe here; for woodies, it's definitely zone 5. +More So - that's a little too inconclusive for your catalog, Diane, but I guess it supports Steve's observation that they're definitely hardy in zone 6.

I have them in large foundation plantings as well as an exposed raised bed and find them equally hardy as long as the corm itself is planted deep enough that it doesn't become frozen through. The raised bed plants come up around 3 weeks earlier in the Spring than the foundation plantings. This I assume is due to the soil temperatures increasing faster in the raised bed.

From: DeniBown at aol.com on 2000.08.01 at 04:29:23(5191) My personal experience may not be relevant, as I live in the UK, but I have found it much hardier than gardening manuals say. For instance, the Royal Horticultural Society's A-Z Encyclopedia of Garden plants gives "minimum 5 degrees C (41 degrees F), while my plants stand several degrees of frost. First I planted surplus tubers at the base of a wall that stays warmer and drier than the border. When they survived and multiplied I then tried them in the open ground and last winter (which was pretty mild though of course with some brief frosty spells - and loads of rain) they came through again, no problem. I live in Norfolk, which is not a particularly warm area of Britain. Also we don't have hot summers, but they grow very nicely just the same. Plants currently have leaves 60cm (2ft) across, with leaflets 30cm (12in) long, on stems 60cm (2ft) tall. From a single tuber, most plants now have four or five other leaves in addition to the main one that develops after the inflorescence withers. They have infructescences developing at ground level too. +More I have also found that plants grown in the open ground, rather than in pots, get much bigger, stay much healthier, and multiply faster. They form very handsome clumps of leaves and in my view should be much more widely grown as garden ornamentals. They are also happy in full sun, which most arisaemas don't like. Even in areas that have a hard freeze, they could be treated like other bulbs, and lifted in the fall. Next winter I'll try to keep records of actual temperatures. Hope this helps. Deni Bown

While winters are mild (350 days without frost), they are very wet and chilly. Sauromatum venosum survives the winter there without any obvious problems with rotting of the dormant tubers. +More I now live in Atlanta and have them growing in the garden here. They are down about 6 inches and have survived winter nights down to as low as 0F. Technically we are zone 7b here in the city and 6b-7a in the suburbs. I have friends who have them in the ground in zone 6a. -----Original Message----- From: Diana Reeck [SMTP:dianar@teleport.com] Sent: Saturday, July 29, 2000 12:01 PM To: Multiple recipients of list AROID-L Subject: hardiness of Sauromatum I am looking for information about the hardiness of Sauromatum venosum.

From: "Wilbert Hetterscheid" hetter at worldonline.nl> on 2000.08.01 at 04:31:01(5196) Steve, Hardiness of tropical plants is not a very popular item among Euopean plant lovers......... ESPECIALLY not testing it!! Typhonium venosum and giganteum are indeed the toughest ones. My guess is that the Chinese high-altitude clones of T. horsfieldii may also prove to be more temperate than others but all other species I grow seem to thrive too well in a greenhouse to believe they wanna be elsewhere.

My T. venosum are in a 15 litre pot in an unheated greenhouse and are rested as dry tubers sitting on open mesh staging in the same greenhouse (absolute minimum last year minus 10, average minimum 1). The plants this year have three to four leaves per tuber, largest leaf 1.2 m. tall with a blade spread of 53 cm. Inflorescence on this largest plant was 46 cm tall. Pete +More Peter C.
