Just wanted to post this picture of two sikkimensis bananas and a moso bamboo to the right. As you can see the banana to the left is much more red than the other, but they come from two different seeds which probably explains it.
These bananas are the one who have grown by far the fastest and the center one has already produced 2 pups. The bamboo has also been growing incredibly fast dispite the cooler weather and has reached 1m (planted it out when it was about 20cm).
