Czech Rhododendron Series

Czech Rhododendron Series

The varieties included in the Czech Collection were bred at The Silva Tarouca Institute for Landscape and Ornamental Gardens, Pruhonice, Czech Republic.
They are distinguished by their exceptionally attractive flower colours and very abundant and long blooming. Some varieties are additionally characterized by their particularly durable, compact inflorescences, that can flower for over 3 weeks. High resistance to sunshine and drought, fragrant flowers or intense red shoots are some of their other, unusual features. Most of the varietes are resistant to -24 °C. All of them are outcome of years long breeding work and very rigorous selection, that resulted in varieties with attractive foliage, good plant habit and high resistance to diseases.
