Typical maximum recommended spacing for bee pollinated plants is 100'. The closer they are, the more like they are to cross pollinate. Even plants planted much further away can be cross pollinated, but chances are reduced with distance.

Thanks everyone!! Now I can buy more!!

i have never bought a pollinator for any plant ... and i cant think of one thing that failed for such ...

one some level.. i always wondered if it was marketing hocus pocus to sell extra plants ...

but on V ... which is not an UNcommon plant.. it bewilders me to think there arent enough of them around ... that you would need such ...

to think.. that suzy... needs ONLY bobby ... is not linear ...

if you collect Vs on any level ... than i would bet a shiny nickle .. you will have enough Vs around ... to be rather sure that there will be a pollinator ..

all i would look for.. is over lapping of flowering times ... and then probably not even add that to the purchasing equation ...
