Here's something quite unusual that happened this fall with my seed pods. They split---many, many of them; I'd say a good 1/3rd of all my pods split at one seam or another. I've seen this before on rare occasions with a couple pods here and there, but never to this extent. I'm going to place the blame directly on a recent heavy 5 to 6 inch rainfall received very late in the season here. Prior to that, growing conditions were about as perfect as one could ask for: sunny days, normal temperatures and soil moisture maybe slightly less than average. Everything was shaping up to be a near perfect season. Then, the rains came, pouring rain. Then came a good string of 11 straight days in the 80's with lots of warm-hot sun. This combination must have triggered the inside core of the pod and seeds to re-grow larger and the outside shell, while still green, was no longer elastic or growing.
