São Paulo city is about 1000 mts high...........
I use to keep other Erytrina species that I got in my trips..........like Erythrina mulungu.......E. verna............E. crista-galli..............
I keep these in a more higher place..........1200-1400mts.........that my family use to have a small land............about 50 km from the center..........
Top of the "Serra do Mar"................it´s a high land for us in Brazil............
Atlantic Forest Realm............
I think that Erithryna can adapt very well................
Once they live in harsh conditions............they seems to be very hard plant............
And also they are considered pionner plants.............
I have no experience with
Erythrina edulis.............
I hope to get some seeds...........or better..........few small plants..............
I´m trying this contact............Fundacion CIESAM..............
