Cobalt blue flowers that resemble butterflies emerge in summer and last all the way into autumn. The plants can cope with light frosts but might need extra protection during extreme cold temperatures. Cut back in late summer to encourage a second flush in autumn and then trim the following year in spring to strenghten new growth.
