Lilac... store in refrigator (at 40F) for 4-6 weeks then lightly cover seed with soil. soil temp 70F & takes 14-60 days to germinate.
Cherry store at 40F for 12 weeks then lightly cover the seed soil temp 65-70F & takes 120-365 days to germinate
IF the lilac is the "old fashion" variety then will be "true" from seed. The cherry will NOT be like the parent....


No, they don't need to be pre-treated. So I disagree :D
I have pansy volunteers popping up ALL season long...then they just hang out until cool fall, get a burst of growth and start blooming. I'm talking self-sown seedlings from last year as well as from current spring/early summer plants. They keep right on popping up until hard frost and those that don't bloom this year yet will winter over to start bloom late February.

Thanks for the info. I was worried that the leaves were looking chlorotic because of too much exposure. Do some seedlings simply start off "yellower" and much slower than others?
By the way, I was wondering how many times more powerful sunlight on the earth surface is compared to a measely 2-ft fluorescent tube. I read that the power of sunlight is about 1000-1500 W/m^2. How do I compare that to 1360 lumens or 18W from a typical fluorescent?

Here's a guide that might help. I use 1000 watt HID metal halide lights and have been very happy with the results.

I planted some Jacaranda seeds back in June of this year.
I had a chia herb green house left over from last year that didn't make it. I put the seeds in the little pots.
Before I knew it they started to grow. Which surprised me cause the seeds were a year old. But kept in their pods in a cool dry place.
Once the litte trees reached top of the plasic green house I moved them to a bigger pot (5" dia.) And they both seem to be doing great! They have been sitting in my kitchen window (one to the south, and one to the east) The funny thing is I thought they were getting to much sun so I brought them down to the counter top and they both started to go limp. Put them back up in the window and they perked right back up.
The little guys will be headed to their future home next month. I will be putting them in a bigger pot so my Dad won't have do it. He wants it as an indoor plant and put it on the patio during the summer (zone 5/6) and make more of a bush of the tree. I think he only wants it to grow 3/4 feet. So I was thinking of a gallon pot for each of them with good soil. The little trees themselves are about 6 inches tall now.
I am just so happy they grew and are still alive. :)

I see its been a few months, but see the thread for "winterizing a Jacaranda." On this thread there was a gardener who had started 10-12 seeds and had plants that were of good size. They will have some good advice for you. Good luck! I love my Jacaranda.


From what I've read on several sites, it will take at least 3 years for your plants to produce fruit. Some have said it will produce a fruit similar to the parent, some have said you might get a surprise :) I've got seeds I'm planning on planting myself, but I have no idea what a "rapid grow" solution is. And 200 days in the fridge? Wowzers..I'm guessing if you're going to grow these, you need to be in it for the (very) long haul. With loads of patience.


These seeds don't store especially well, you'll have better germination if you sow them fresh, cleaned, using the warm, cold, cool method described above. How do you feel about dealing with a seed pot in the middle of a household move :)

If you are talking of removing plugs from their trays without damaging the trays or the plugs, we just turn the trays upside down and push the plugs out with a dowel through the hole. If your plugs won't take that they are not ready. Al


Store seed at 40F for 12 weeks then lightly cover seed soil temp 65-70F & takes 120-365 days to germinate.
It should be noted that the seed are used ONLY for rootstock to graft on a "good" cherry. From seed the plant is NOT exactly like the parent. it takes a long time to flower & produce fruit.

I never heard of using peroxide, but here in La. I understand that some people use clorox.
Regarding h peroxide, i received an email giving many uses but not for seed. It did say if you have a fungas on the toes it would help. For about a month now I have spraying my big toes with it and it looks like they are growing clean.

Germination will now be best at 60F. (so take out of frige) After gets 2nd set of true leaves (4-8 weeks) may transplant to larger pot. Takes 20 weeks to produce a large enough plant to set out. Soil pH 5.8 to 6.8 & requires high fertilization. will need to provide a location with "good light" & a soil temp 55-60F will then be ready to set out (spring) after danger of frost has passed.

I am sorry about the double posting. I posted this msg, then later on pressed reload and that created the second post. Dumb.
Thanks for the reply. I guess I'll take it out of the fridge now and put in the back bedroom(unheated).
Hopefully I can baby them along until spring. If I remember, I'll update this post in 6 months.





They sure do...
If your pods are green and seeds tan, they are a little short of being ripe yet.
Most garden forsythia are cultivars and don't come true from seed - also, they are so easy to grow from cuttings (which doesn't mean you couldn't have interesting plants from your seed). Sow outdoors, or provide moist cold of minimum of 30 days, followed by sow at 55F, germination in an additional 30-90 days.
