If you've ever been hard pressed to find a plant there is a place where you can find out where to buy it, plantANT
You have to sign up / register to use it and it is for the trade (but at least you can find who is selling it) In my travels Ive found many places will
sell you something something retail if you ask them and some wont.
* if you sign up, just use a name like SAMS SEEDS or BOBS BANANAS etc.
When I signed up they had already approved me before I went into mail to activate my account.
Below is a sample I ran for a plant that Fred had been looking for....hmmm..Donna,TX is a long ways 'over younder'...but who knows, they might mail him one. (Fred 1g $15) https://www.plantant.com/find-plants#!name=trichocereus&plant=1022889
