This beautiful shrub has rather strange-looking yellow flowers with the upper petal being bright red. This combination of yellow and red makes the flowers quite attractive. With good watering, the shrub will be covered completely by these flowers. At the end of the blooming season the seeds still continue with this yellow-red theme, because they are reddish and begin to appear while there are still plenty flowers on the shrub.
It is not a fast grower, and you can expect the first flowers to appear in about three years. Not very tolerant to extreme cold climates.
