This is an ornamental blackcurrant, grown purely for its flowers which are much more showy than its edible cousin. For me, this symbolises spring as for some reason it was a popular bush where I grew up and I walked past a number of them on my way home from school. They have a very particular scent which travels on the breeze on a sunny day like this one. So when it flowers, I know spring is underway, and the scent takes me back to sunny afternoon walks towards home - it's a very evocative plant for me.
It's easy to keep flowering each year - after it has bloomed, I cut out one third of the branches, reshaping as necessary. That's all it needs.
