About those seeds - an educated guess?
1. Bulb plants usually make seeds, too. I collected Paperwhite seeds this year. (Why? Because they were there.)
2. The Moraea family includes Fortnight Lily, which delivers some the the hardest, most persistent seeds known to man. In general, South African plants make seeds that will wait out many a bad summer till the rains come. Pretty tough plants!
I'm guessing your seeds will be just fine as long as they're kept dry and cool. Glass jar in the fridge.
I'm jealous.
