tonyc Posted October 4, 2006 Report Share Posted October 4, 2006 Hi, all. I'm looking at expanding my (presently very small) collection of these, and rather than just relying on Google I'd be interested to hear of other people's experiences in sourcing them. A particular problem I've experienced is that some websites seem to be hardly (if ever) updated. If you don't have a plant in stock and you aren't sure when (or if) you'll have it again, why list it? Grrrrrrr. Cheers, T. Quote Link to comment Share on other sites More sharing options...
Bob H Posted October 5, 2006 Report Share Posted October 5, 2006 What Aroids are you growing and what ones are you after? I've grown Arisaema for a couple of seasons, about to put them to bed for this year, and have had little problem, apart from finding room for them over winter.

gardenofeden Posted October 5, 2006 Report Share Posted October 5, 2006 Bob how do you treat over winter? Quote Link to comment Share on other sites More sharing options...
Treefrog Posted October 5, 2006 Report Share Posted October 5, 2006 Next summer I will be able to send you guys seeds of Ariesema triphyllum (3 varieties) and Ariesema dracontium, maybe some Symplocarpus if you can bear the scents. All the best Quote Link to comment Share on other sites More sharing options...
Bob H Posted October 5, 2006 Report Share Posted October 5, 2006 Bobhow do you treat over winter? Hi Stephen, I just let the dry out, kept at min 7C ( I think they could go lower). When fully dry I tip them out and re-plant in fresh, dry-ish, media. When they start to shoot again, water and back outside. PS The Arum you sent grew well but no flower :-( Think I lost the Drac in the heatwave tooooo dry! Quote Link to comment Share on other sites More sharing options...
Guest Sheila Posted October 5, 2006 Report Share Posted October 5, 2006 I kept my Arisaema in an unheated greenhouse last year. It wasn't a particularly cold winter and the coldest they had to endure was probably -4C, They all survived and grew well this year. Some of the little corms I was sent in exchange for some of my spares have grown huge this year, so they can take pretty cold temperatures. Like Bob I just left them in the pot until the media was bone dry then repotted them into fresh dry media and waited for signs of growth before putting them back into the garden to grow and flower.

pulsar Posted October 5, 2006 Report Share Posted October 5, 2006 most arisaema in cultivation are perfectly hardy the only reason to overwinter in a unheated greenhouse or coldframe is drainage problems in the pots over the winter.even so you would have to make sure they dont become to dry rob Quote Link to comment Share on other sites More sharing options...
Guest Aidan Posted October 6, 2006 Report Share Posted October 6, 2006 I leave all mine to dry totally over the winter and don't water again until there are renewed signs of growth in spring. Quote Link to comment Share on other sites More sharing options...

Steve_gts Posted November 1, 2006 Report Share Posted November 1, 2006 I have a Dracunculus (or however u spell it!) and it was outside all winter last year, I just chucked a couple of inches of mulch over it to protect it from the worst, I can't vouch for how it would deal with a lengthy snow period though.

Rob-Rah Posted November 1, 2006 Report Share Posted November 1, 2006 Dracunculus is quite hardy without extra protection unless we get prolonged subzero temps for several days at a time. Have to avoid the tuber freezing solid, but as it's underground it seems quite resistant to it. Mine have been outside in SW London for 4 years with no extra protection. Snow might well help insulate it in a way that prolonged freeze doesn't. I also leave my Arisaema outside all year, but they are planted deeeeeep to insulate against cold. Around 8"-10" deep.

Guest Aidan Posted March 11, 2007 Report Share Posted March 11, 2007 Not ten minutes ago I spotted Arisaema thunbergii surfacing. Owing to neglect, the pot has been outside all winter. Quote Link to comment Share on other sites More sharing options...
Alexander Nijman Posted May 12, 2007 Report Share Posted May 12, 2007 Hello, Dracunculus vulgaris has survived here in Leidschendam, The Netherlands, the coldest winters, down to minus 16 and more! Give them some mulch of leaves in the autumn on a sunny well drained spot and they will be fine. Regards, Alexander Quote Link to comment Share on other sites More sharing options...
Bob H Posted May 12, 2007 Report Share Posted May 12, 2007 My Drac survived, no flower this year. The first of my Arisaema, cilliatum, has poked its nose up. I had changed my rule and put them outside during the hot spell in April and let them alone. Quote Link to comment Share on other sites More sharing options...
gardenofeden Posted May 12, 2007 Report Share Posted May 12, 2007 My Drac survived, no flower this year. they tend to flower mid-late june for me, after the foliage is out, unlike most aroids Quote Link to comment Share on other sites More sharing options...
