    ...is there anything special I should know about it, like dormancy, flowering, viable seeds, vegetative propogation,...?

    Sorry, I forgot to get back to you on that. D. 'Ivan's Paddle' is a D. x obovata tetraploid created by Ivan Snyder. The parentage is [rotundifolia CA tetraploid x anglica (CAxHI)]. Treat it like a tropical form of D. rotundifolia or anglica; it won't need dormancy. Flowers are white and also sterile. Here's a pic of mine:

    Peter, do you propogate by leaf cuttings or will it send shoots of plantlets? Would a S facing window sill be appropriate? Is it fine as an open tray plant?

    I propagate by both cuttings and offsets. As you can see in the picture, the plant readily makes offsets. In my experience it does not produce shoots the way D. adelae or D. prolifera do.

    I grew in a tray under lights for a while, but since I put it outside in a terrarium its really taken off. Again it doesn't need dormancy, but I'm not sure what the lower limit is temperature-wise. I'd do an experiment but it doesn't get cold enough in southern CA

    Hi--we have both D. rotundifolia and D. anglica here in southcentral Alaska (around Anchorage) coexisting in the same bogs--so D. x obovata are possible here. I haven't found any D. x obovata yet, but it's not for lack of trying--that said, winter temps in Southcentral here can range down to -10F to -20F for short periods at times. How's that for a lower limit temp-wise?

    That's a very cool sundew. I've always wanted a D. rotundifolia - type plant that wouldn't need a dormancy.

    Mike, my guess is that with your winter temps this plant would probably form a winter bud, just like the D. rotundifolia "evergrow" does in cold enough conditions. What makes it tropical is that it doesn't automatically form winter buds when it decides the growing season is over. I could get you a plant in maybe a month or two if you want to experiment.

    LG, I heartily agree. The north american dews are all great plants. I know of "tropical" forms of rotundifolia, anglica, and intermedia.

    I've had plants that both formed and did not form a winter bud from the same seed batch. I think Mr. Ivan Snide r did too, and he culled the dormant type. I doubt the plant would survive artic conditions, even with hibernacula. Mine didn't and we hit those lows here in Oswego. Keep looking for that D. x obovata!
