I’ve grown this plant in the garden for the best part of ten years. However legal problems, which didn’t involve us, has made this poor plant impossible to sell lawfully until the last couple of years. A hybrid between G. wallichianum and G. himaleyense, it is much tougher than either of its parents and more beautiful, producing masses of large flowers from spring until late autumn, clear blue during cooler weather, mauve blue when it’s warmer. Sun or light shade. Thoroughly dormant in the winter with not a glimpse of a leaf to be seen. 50cm x 50cm.
