I selfishly like to keep a regia growing over winter under lights, I have three pots of larger plants that are all black outside. This one was a small shoot I rooted earlier in the year

How is your last plant doing? I just got some R. dentata seeds today and am trying to figure out how I should handle them. Could you be more specific about when the seeds germinated and what day/night temperatures they experienced around that time?

The surviving plant isn't doing much at all but surviving just about, think it's too cold where I'm keeping it for it to grow. I'll be pleased if it makes it through the winter months alive and expect it to start growing again with some warmth in the spring. As for more specific information on germination temps I'm afraid I've forgotten but probably got below 10c at night , sorry I can't be of more help but I do remember reading that low temp periods can help with germination

My R. gorgonias plant sits in an unheated room over the winter, rarely seeing temperatures above 5C. It doesn't really grow much but it does ok. R. dentata is probably much more sensitive to that sort of treatment, though. I wish I had a nice sunny window to put it in, but alas I don't.

Cheers, it makes me a little more confident knowing your plant acts similar in the cold conditions, I could of given it more hours light and warmer temperature but I decided to try and simulate a natural winter in the hope of getting flowers, but that's a big hope :-)

I tried to burn some dead Roridula gorgonias leaves to make smoke water, but they don't burn as well as I'd hoped (despite reading reports that the leaves of these plants go up in flames like they're soaked in gasoline) and it doesn't seem to be infusing water very well. I will give it a shot just the same with half my seeds, and soak the other half in a commercial liquid smoke product I was given a sample of by another local grower.

I remember reading that"up like soaked in gasoline" account, funny (or not) how much some things are easier said than done, good luck . I noticed with this years seeds just how slimy the seeds went after soaking , I forgot to scarify with fine sandpaper like I did last year and now its like trying to hold onto miniature bars of wet soap, so it aint getting scarified. Live and learn :-)

I don't think scarification is very useful for these seeds, personally. During the smoke water soak, it seems that water had no trouble penetrating and the swelling seeds actually seem to be causing the seed coat to break on more than one.

I hope you're right and will post my results good or bad

This looks suspiciously like a developing root to me, 6 weeks after sowing. I'm pretty sure that little red nub wasn't there a couple days ago.  Roridula dentata by Nimbulan, on Flickr You can see how much the seed coat has split purely due to the water soak, and while this particular seed has shown the most seed coat splitting, most of them are showing at least some of that. |

Looks promising , just checked on mine and definitely got germination on one but didn't want to disturb the others to look , my phone won't take a very good pic , but I appreciate your macro:-)

I certainly understand how difficult it is to get that close of a picture. I use a lens reversing ring on my SLR when I want to get this close which requires holding the aperture lever on the back of the lens (front when reversed) open with my finger while I'm trying to get the subject in the incredibly narrow depth of field. It took me 3 tries to get this picture, though it's taken me quite a few more in the past.

 not up to your standards but not from lack of trying:-) |

That's still a great picture. It looks like your seed is a little further along than mine. How long ago did you sow them? I do have at least two seeds starting to grow myself, and hopefully more to come.

I sowed them on the 21st January , the other seeds have split but this is the only one showing growth
