Bought four or five ($8) 'sea beans' mucuna sloanei, last year after finding one (first time in my long life) washed up on the beach. Fair Dinkum had them and they arrived for mr to admire. Planted one (with care instructions from FD) and it took off.
A great variety of unusual and hard to find seed.
I'm spreading the word to gardening friends.
Great people, great service and advice when sought.

Approximate cost: $8
