This bamboo type plant was originally my MIL's in a pot and when she moved away I somehow inherited it. It was quite rootbound and seems to enjoy being released from the confines of the pot. It has had a few red berries, and then suddenly in the last couple of weeks put out these lovely long stalks.
Here they are in more detail.
I know different types of bamboo can run rampant, but think this looks more of a clumping type. Not even sure that it is a type of bamboo. The yellow spots of the leaves were quite distict, but I have been watering with a weak epsom salts solution and they seem to be fading out. Not very scientific, just thought that might be what they needed. This soil was very poor - had been under a pile of rocks for years, so it probably needs all the nutrients it can get.
I couldnt resist picking some lovely passionfruit flowers and floating them with some candles the other night. They smell divine!
Someone on KGI suggested making tea out of them - I must try it sometime - they only last a day, and then shrivel up into a ball - I suppose that is when you would dry them.
