Locust tree.

I have got some Locust tree seeds sent from USA and would like to know when to sow them ... help please .

 

Now isn't reallty too late, I sowed a couple in late August a few years ago picked up in Florida.
The tree got to 8/9 ft in a glasshouse but was too big to keep and never had any sign of buds coming on it.

 

Honey locust or black locust?
Gleditsia or Robinia?

Gleditsia Triacanthos I have grown from seed.
I found it best to chip the seed coat and soak for a few hours first, before sowing.
