Weed or Treasure?

2nd of a few unidentified plants in our inherited garden.

This plant seems to have been purposely planted along the back fence. I thought maybe a Pelargonium....but do they get this big? It's survived the few light frosts in YVR but was a bit wilty this morning after last night's chill.

Any suggestions appreciated!

 

Probably Lavatera x clementii. Bunchy habit may indicate a pest or pathogen is at work.

 

Your Lavatera...prefers more direct sunlight, but will easily survive a Vancouver winter, ahem... mabe put to task for last winter... let's hope that it will not be a repeat....

 

Thanks much! The "?" on my new plans are slowly being erased!
