Haba ShanMuch in demand at our nursery, R. hippophaeoides var. Haba Shan has wonderful blue flowers that delight the eye. Hardy to 10 deg. F, it is tolerant of sun and even swampy conditions. It will even withstand a hard frost when in full flower. The flowers are small tubular in shape, are a lovely lavender blue, and seem to show themselves several times a year. The plant will only grow to 3ft x 3ft in 10 years, so it can go toward the front of the border
