Native buckwheat or cover crop buckwheat? I grow both, but on the coast. The cover crop kind likes heat.

If you mean Eriogonum, I have E. arborescens, E. umbellatum and a small coastal E. grande rubescens. They all do extremely well in the heat in Fresno. In fact, we have several native Eriogonums in the Central Valley.

this is the one i got.Variety: Mancan.i want to plant alot of them for the bees :)

Ah! Green manure and buckwheat honey! It's a warm weather plant and you can plant it now. I usually plant it in July or August. I plant Bob's Red Mill. You also might like to plant California buckwheats (Eriogonum) as a perennial ornamental. It's also popular with the bees and, of course, well adapted to our climate.
