As Tracey says, martagon seed pods get very fat, and you should notice the difference (compared to asiatics) in just a couple weeks' time. Martagon pods also have six very noticeable wings. These are the largest pods I've ever had, but the size isn't too far off from normal.
Compared with a typical asiatic:
As Lorn mentioned, pointing toward the sky is usually
an indication of good seed to come. In the pic below, it's easy to determine that all but one of these were not
successfully pollinated. But what about the one on the right? I had wondered about it, too. In this case, it yielded many fertile seeds that I have germinated.
On the other hand, here's some more questionable pods. Lorn had predicted they would not produce good seed, and he was right. None of them did, and all they contained was chaff.
