Penstemon

Exuberant and unusual, the Penstemons bloom throughout the summer, bringing joy and color even when the other plants, for the oppressive heat, take a break. It originates from North America and it belongs to a particularly small variety that grows in the mountains on stony ground, very close to the ground. The plant forms several spikes, which are covered with many small flowers similar to the bells: blue, purple and red. It needs full sun and it is resistant to cold.
