That's kind of hard to say. I suppose it depends on how long it takes for the flowers to turn to mature pods. The fact it has set flowers ALREADY is a good sign, but I know many plants that can take a long time from flower to seed.
On hopeful thing is that, if YOU manage to get seed, it means I probably will when I plant my seeds next year or so.
BTW those blue kissed white ones I mentioned are now available from Trade Winds, who I THINK are authorized to sell in Canada (
