Unfortunately, my camera cannot seem to capture the special brown tone, which makes Brownie so unique, which is why I haven't added any pictures of it to the database.
As for size, I only had mine for 2 years now and it is not enourmous, but it has grown to about 2 meters tall so far and it is quite bushy compared to most of my other climbers, so I expect it can grow rather large - depending on how cold the winters will be of course.
'Purple Tiger' is not exactly the best grower I have ever tried...
But in its defense, I must say that it doesn't have the best spot in my garden, as it grows next to a hedge in a very dry spot. I water it, but it is struggling.
