Poor germination, but better than Empress of India. Weak plants. Not impressed.

I am quite new to gardening so I am learning all the time. I bought these for my hanging baskets and they were easy to grow and they are really beautiful but too vigorous for what I wanted. I will definitely buy them again as the bees love them as well but I will plant them elsewhere

Everyone should try this - so different to the 'common' choice. Yellow and orange not a favourite of mine - so glad I found this.
