Well I had a surprise today! I was watering my jungle corner (hibiscus, banana, drago, monstera, honeysuckle) which, as usual, is slightly overgrown, when I heard a dull thump. Turned off the hose and forced my way in and to my surprise found a stalk of bananas on the ground between the plant and the wall! Didn't even know it was fruiting - it was very well hidden!
my jungle:
elsewhere in the garden the red banana plants have eventually started growing well - they took a long time to get going.
