I did a search to see if any members here have it as seeds or listed under plants for trading, and see there are 10 members listed who have it for trade.

If you have seeds to trade I would suggest you either put together a seed trade list, or post at the Seed Exchange "Want
Laurus nobilis 'angustifolia' aka 'salicifolia' aka willow leaf bay laurel.
and list in the post what you have available for trade.

Good luck!
