Description and Distribution:
It is native to Southern China (Sichuan and Yunnan) and Northern Myanmar. A striking species and the closest that any Iris comes to having black flowers. They are not true black, but such is the depth of colour of their velvety deep-purple petals that they appear so. Our plants have been grown from seed and as they flower we have selected the dark forms. Grown from seed has also produced a percentage of plants that have deep blue flowers. Height is around 40cm.
This iris was discovered in Western Szechuan in 1908 by E. H. Wilson and introduced to British gardens in 1911. References indicate that it is likely that the first lot of seed of this iris was raised by Miss Willmott at Warley Place in England. A lady of independent income she was able to subsidise the excursions of plant-hunters who, as well as bringing her plants, repaid her in the usual way, by naming some of the species they discovered after her. Ceratostigma willmottianum was discovered by Ernest Henry Wilson, who also named Corylopsis willmottiae and Rosa willmottiae for Miss Willmott. There is also Iris willmottiana, Iris willmottiana ‘Alba’ and Iris warleyensis and Aethionema ‘Warley Rose’ and ‘Warley Ruber’. (Such an interesting person that we will write further about her at a later date).
