I am wanting to know how close another Desert Willow needs to be for it to become pollinated (as these trees are not self-pollinating)?

I also more recently read that there are cultivars which are seedless, and am now wondering if one of those might be what I have planted...?

It didn't have any cultivar name on it when purchased, though, just "Desert Willow" &/or "Chilopsis linearis" (I forget which).

Chilopsis linearis (Burgundy Desert Willow):
