Assuming the Saga tree is still there and fruiting, it should be more than enough. But then again, I don't know how many you need, but I guess you can easily find a hundred seeds from one tree given the right timing. You should bring your girlfriend there and pick together, I think that's more fun.
Hey ... I didn't know the name of these red seed is Saga.
I only know it's call 相思豆
Thanks Allen ..it's a lesson learn for you.
Here's my sags seeds. I picked them from a work site 2 years ago.
Kept them in a test tube ... almost forgotten about their existence had you not started this saga thread.
Looks like it's "no maintenance" as it's still shiny and hard.
The place I found them is a private estate ... no access for public.
I do see these seeds being sold together with fancy bottles in gift shops.
No idea where ... but I believe you want to pick some yourself.
