I managed to get some sent over from a chap called Steve Heil - but he seemed to have disappeared from the pages of the internet.
The only way to get some - if I didn't want to pay $35 to get some posted to the UK - and I didn't - was to grow my own.
It proved a tetchy germinator - mostly because it is a high sea level plant and I was growing at practically below sea level in North Norfolk England.
6 plants were planted out and began to put on strong growth.
Yesterday I cut the first crop, leaving the plants in the earth to grow another set of leaves stems and flowers and I now have almost 20 small bundles drying in the storage area in the studio.
First 2 small mugs of Navajo Tea drank yesterday were like nectar. The research into the plant is interesting too, Thelesperma megapotamicum contains Luteolin and is Hepaprotective and cancer preventive - handy for someone with autoimmune liver disease (PBC) and throat cancer in 2011.
