There is a big problem here in the Philippines of sourcing good seeds/seedlings for those of us who want to use underutilized crops for food security.
Online markets have many people who import and repackage seeds with bad germination.
There are also laws which prohibit importation via mail or carry-on without proper certification.
There are plants like Queensland arrowroot that has a nice tuber that I can’t source. Plenty of canna edulis/indica here which are ornamental.
If you know of good sources of plants, or seed exchange in the Philippines please share.
