In the latest post I casually mentioned my observations regarding the behavior of Avonia albissima branches with ripe seed pots. I find it quite interesting. Apparently, the branches that otherwise lie flat on the ground at all times suddenly lift when the seed pod has ripe seeds in it. I've been watching the flowering Avonias closely since then and it happens regardless of whether they've been watered or not. Recently a couple of my Avonia quinaria plants have been flowering, too. They are normally not self fertile but it still happens from time to time that a seed pod develops. This time it happened again and look at that! The branch with a ripe seed capsule goes way up while the other one lies on the ground.
I've developed a theory as for why Avonias are doing that. Completely unscientific of course!! :D You know, ripe Avonia seed pods workings are the opposite of Mesembs. The seed pods close up when they are wet and open when they are dry. Not only lifting the pod up to the sun makes it dry quicker and throw off the rests of the old flower it also surely helps distribute the seeds better with the wind. Moreover, if it happens to rain and the seed pod is on the ground it will be much wetter and therefore sealed for longer time. If it's in the upright position when it rains the pod can dry quickly in the sun and the seeds fall out before the ground dries ensuring better germination chances. What do you think?
