That's odd, does it happen at the species level? I guess it must given how many of the sections haven't entirely intermingled.....I wonder what the evolutionary advantage of the delay would be.
Approx 2 weeks later, one of the eyeliner pods is swelling noticeably more than anything else. One of the longiflorum x honesty pods (don't think it will reach maturity but you never know) is also noticeably larger than any of the other longiflorum pods. Straight 4n x 4n asiatic nothing noticeable so far.
But seriously, it's really slow swell up compared with most flowers out there, it's usually super obvious as soon as petals fall off...I just find it super odd.
