I know Duguetia is still somewhat of a newer species for growers in the United States, maybe even somewhat of a novelty but I figured why not start an official thread dedicated to these trees for any progress, insights, and updates.
In my experience so far, I've lost quite a few when the seed casing either doesn't separate on its own or the cotyledons rot while in the seed. Those that do germinate properly seem to be extremely slow growing.
Here's some species I currently have growing
Duguetia confusa: these are probably coming up on 2 years old

Duguetia sp yellow Joao: I have a feeling this one is going to be reclassified eventually as not an actual duguetia

Duguetia lanceolata

Duguetia stenantha

Duguetia salicifolia

Duguetia marcgraviana "gigante de rondonia"

Recently had duguetia surinamensis sprout but then die back, pretty bummed about that one
