Hi.

I think the question is related to seed germination but Hardenbergia being an australian native, maybe you guys could help me. I am unable to germinate seeds of hardenbergia violac. I tried boiling water, scarification, soaking in water(seeds did swell) but none worked. I have a temperature of around 20-25 these days, late spring early summer. any tips? Should i try zip lock baggie method after seeds swell up?

Rub them lightly with nail file or sandpaper just enough to break the skin,soak overnight then plant .^_^
Good luck.

Crissy, thanks for the reply. I already did that. But no success. The seeds are from Chiltern Seeds UK.

Khabbab, I took seeds from my Hardenbergia violacea and just put them straight into seedling mix and watered and up they came. Maybe the seed is not fresh. Your temps should be okay so the next lot you try I would do that. Good luck. Colleen

Something came up but i doubt if it is hardenbergia seedling, instead something else. Can some one confirm if it is hardenbergia seedling or not? The second set of leaves does not look like hardenbergia but maybe true leaves still to come.

Thanks

Khabbab it looks like a Cedar tree. I do hope you find those elusive Hardenbergia. Colleen

After i have failed all the tries for germination, i complained to the Chiltern seeds UK the sellers. This as their reply:

We think that they could take many months to germinate and they will also very probably benefit from stratification/exposure to cold.

Now should i try cold stratification? Because if seeds are good and seeds do swell after scarification and i tried all possible mixes for germination but no result.

I bought some packets of vermiculite which had been "Soaked in smoke". The explanation was that these Au peas pop up after fires, because of heat, and smoke, so mine have been scarified, soaked overnight in warm water, they are in moist paper towels and when the roots come out, I will mix the vermiculite with the potting mix & put them in that to see if that helps. Let me know how it works out for you. Judy Showers.

Still waiting. I have had these packets of vermiculite soaked in smoke since last year. maybe the smoke all leaked out (smile). Guess I gotta look up one of my cigarette-smoking friends & see if I can get them to breathe on the vermiculite and/or the beans which have been nicked & soaked.

You put the seeds on 2 of sheets of newspaper and burn the newspaper, when cool soak in warm water overnight (or two nights) until you see the seeds swell.
The seeds may be no good if that does not work.
Fresh from the pod seeds do not require this treatment, but older seeds do.
Good luck with them. Don't use fertilizer on the seedlings and don't over water.

Chrissy, but I have already nicked & soaked the seeds. Will that harm the seeds once they are nicked & soaked? Some of them look green inside the shell. Any help you can give would be greatly appreciated. Thanks, Judy Showers.

p.s. I forgot to mention that I sprinkled a little of presmoked vermiculite in the moist paper towel with the seeds. Maybe that helped?

I don't know if it will harm them once the seedcase is penetrated.
Did you soak them in very hot water ?
I would imagine if they are green inside, they are still viable.
Soak in hot water overnight then place between wet kitchen paper into an airtight baggie in a warm place.
I can only tell you what I would do,
If the seeds swell in the hot water, then they are ready to plant out. You won't need a baggie treatment.

This link may help.
I know it contains most of the info you have been given, but may be helpful anyway.

Well in my case, seeds do swell with scarification and then soaking in warm water but do not germinate afterwards. How can i check the inside is green or not?

I guess I will be planting my seeds tomorrow. I looked up the mix & it said 80-85% washed river sand to 15-20% peat and that could have been part of my problem, not using the correct mix. Will let you know if they grow. Thanks for your help, Buttoneer (Judy Showers, Carlisle, Pa USA)

Well, I ended up planting the seeds a short while ago since they were beginning to sprout!!! Yea! I have had these seeds for a couple of years and am extremely happy that some of them are sprouting. The ones that I noticed Sprouting were the black Kennedya nigricans and white Hardenbergia violacea var. alba. Here's a picture. Not sure which one these are but they are rooting.

Khabbab, you can see the green color right through the seed coat but the key is making them swell. After mine had swollen, I put them in damp paper towels and put in a plastic bag for a couple days and planted when I noticed them beginning to root.

I think birds are dropping seeds in your garden!

This is Hardenbergia Violacea:

The leaves are long and narrow, about 2-1/2" long, flowers quite tiny, but very beautiful.

The seeds need to be in the ground when a bushfire goes over, which is very quick. Try collecting a very dry grass and put it on top of the spot where you have planted the seeds and set fire to it! If you have any growing in your area, collect some dead gum (Eucalyptus) tree leaves and add those to the grass, it may help?? Then water in the ash.

Best I can do!

Good luck
