I may have lots of native Texas flowers growing in my garden but there is one European flower I can't resist having. The foxglove, Digitalis purpurea. The tall spikes with their tubular flowers were always in my fairy stories, which I read as a child. They are the quintessential English cottage garden flower.
I have tried to grow these flowers and have been successful in growing them through the first year of their biennial life. Last year I had gorgeous rosettes of green leaves but never a single bloom.
I have given up on growing them but couldn't resist this plant. An impulse buy.
