I have a 'Raspberry Ice' that I bought as a small plant about 3 years ago. I wanted a plant that could handle my west facing sunny deck without a lot of water. I planted it into a large pot with an iron tee-pee shaped trellis thingie. The first year it did great and bloomed. The second year it grew but only a few tiny flowers. Last year lovely leaves but no flowers.
I water sparingly, overwinter inside, fertilize rarely. What am I doing wrong? Could it just not like such a large pot? I saw them for sale online in a hanging basket - maybe I should dig it up and try that instead? Please help. The foliage is very pretty with the variegation, but I'd like some flowers too.
