Nemesia – wisley vanilla

I bought one of these last year, because it smells so marvellously of vanilla. I dip to take in the scent every day. The garden centre claim it's perennial but it doesn't look very hardy, and even though I covered the plant quite well over the winter, nothing came up this year, so this is a new one. The photograph is fine but this really wins for its smell which you will have to imagine.
