(In NZ) Planted three of these plants last year and they are fine but had expected lots of flowers .Only had a couple of very small flowers. They are in the shade but get morning sun. Is there a taller variety or one with taller flowers?
I think that they just need time. Mine (planted 2 years ago) also had only very few and small flowers in the first year, but flowered very well this year. I think you just have to be patient.
I think most people grow it for the foliage as the flowers aren’t that spectacular - so enjoy the leaves!
Give it time. They are the most wonderful plants in so many ways.
