What time of year does W. Filifera or Robusta flower and produce seed?

Don't remember exactly, but I think they flower in late spring/early summer while the seeds are ready by late fall.

My robusta and filibusta are already sending out flowers.  Seeds should be ready by late summer or fall.  Both my palms had seeds on the tree when the freeze hit.

Washington Filifera seeds are falling off trees in early November in San Antonio. I typically see the seeds all over the Riverwalk.

They can hang onto seeds for a little while and they are not perfectly all ready in the tree at the same exact time.

Washingtonia Robustas would be sending flower stalk up in May around here. 
 

So it seems like it takes about 5 months.

Key word is would be.  It will be 7-10 years before you see another seeding Robusta.
