The porcelain flower

I was given this plant a few years ago as it had outgrown its owner's space. It has the most amazing flowers which have appeared firstly in March, last year in May and this year in April. Looking it up I see that flowering depends on the amount of light available. The plant has been in the same corner for the whole time so we must have had quite a variation in light over the last three years. It has thrived on neglect! If you look closely you can see yours truly lurking in the background! Have a good weekend fellow blippers!
