This is the first bloom of a cross that I made. I don't have totally comprehensive knowledge of amaryllis, but I've seen more than a few. I have never seen any with spots like this on the petals. Is that unusual?

Wow, is it going to have more than the one flower?

There will be one more.

Yes, looks petty unusual to me - you might be able to market it, I should think.

Very pretty!
Well then...
When you are ready-

This is the second flower. It is not as consistent as the first. If I figured out how to market this, I would wait a few bloom seasons first to make sure the flowers and offsets are reasonably consistent.

You can cross it to itself for seeds. Or, cut the bulb up, keeping a part of the basal plate on each cut part, let the cut wounds dry for while, then plant them to form new bulbs. With only one bulb, I would be hesitant to do that though - if you do it wrong, your only bulb is gone. Unless you can get an expert to it for you. I would go with self pollinating it to get the seeds.
