No, but if you want the plant to make pollen, thereby giving you seed,
then give it as much light as possible. Of course, you will not know
until after the flowers open if it's not enough :(.

The pollen is ready the first and second day, there maybe some left by
the third. The stimgas open on the second or third day. I don't know
how long they last but I would pollinate it a couple times as you could
end up with more seed that way.

Dry and in the fridge.? Probably for a long time = several years.
Maybe decades?

They should be stratified as just about any temperate plant will
benefit from this. Sow in the late fall on moist soil, or on a
moist towel and refridgerate for a couple weeks. This cold
treatment degrades a hormone that keeps the seed/plant dormant.
Not all temperates *need* it but it will not hurt them either.
