A couple of years back, when the City started collecting organic waste, we rather gave up on our apartment compost bin that we had nurtured for almost twenty years. The part of the balcony where it sits is always closed off during the winter months, and what goes on in there tends to be left to its own devices.
Now that I have re-opened the area for the summer, I discover that a plant has colonized the bin in quite spectacular fashion.

It sits next to our long-suffering but always abundant clematis and together they give the area a beautiful look of greenery from the part of the balcony where we sit and contemplate.
The plant also has these delightful flowers. I am sure someone will be able to tell me what it is I am growing here.
