Hello!
Does anyone have any tips for germinating Jacaranda seeds? So far, I've been trying 20 degrees C, at a 16hour daylength in soil in a growth cabinet. I was wondering if they need pre-soaking (priming), or maybe higher temperature? It might be that the seed I have just aren't viable any more, but, the boss would like me to try and find out how to germinate them! Thanks =)

Maybe i should've explained... I live in England... and its winter too, so not so warm outside right now!

Also, a small part of my job is testing seeds for germination rates etc. So, when my boss turned up with these strange-looking seeds, I just put them on germination test like I do with all the other samples.

I think the idea was to just see if they would germinate, but I presume he wanted them for a conservatory eventually, as you suggest. However, this summer IS going to be exceptionally hot here in the UK, so maybe it'll make it outside!

They do NOT grow in SC. Jacaranda is a tropical. In the tropics they like a dry winter, during which they often lose their leaves, then they bloom in early spring (March) without any leaves -absolutely gorgeous. Then, leaves begin form, as flowers begin to drop. Warm temps and rain encourage the full foliage until the dry months, the months that we call winter in our colder climates.
In Florida, Arizona and California they are a landscape tree but winter irrigation messes up their cycle, and they just piddle with their bloom, instead of the gorgeous tropical end-of-dry-season results. Occasionally an old unirrigated yard will sport a Jacaranda in its full glory.
Back to your question - in the tropics the seed pop up like weeds in the rainy season (summer). They must be easy to grow. You may have old seed since they are reticent to sprout. I would try slightly warmer temps. Maybe use bottom-heat. But I would suspect the seed may be too old.
Just curious - is there anyplace they will grow outside in the UK? Or are you producing them for a conservatory ?

I took 20 seeds from a pod and put them in a small plastic cup of water. Placed them on the window sill on the north side(shady, cool but bright diffused light) of my kitchen. Changed the water once a week. They all sprouted in about 3-4 weeks. One is 2 inches tall already. Now i have to transplant a lot of little trees. I am in Southern California, if that helps.
I hope yours have done well by now.

They grow wild here in SC. Boss? Greenhouse?!! Just put them in 1 gallon pots, keep watered, in full sun. Let it happen like in the wild.
