Commelina tuberosa

Still looking good, and I like the colour combination with the Salvia.

I do like these they're such a lovely blue ...

Salvia 'Amistad' and Impatiens balsamina Siris.

It is one of the best blues in the garden Amy.

Nearly bought this one the other day.....but promised myself only to buy reliable tried and tested plants from now on!!

It's reliable! This one is about three years old now.

Ahh but is it going to be reliable near the sea Meanie?

Yes - it's a darned site warmer there than it is here over the winter.
The biggest issue may be the winds taking the mature stems out as once mature they hit about a metre in height.
