Like Axona, Mira is extremely blight and virus resistant - the most resistant variety known. They are both on the floury side of general purpose and effort is needed to stop the tubers becoming too big and starchy - cut the foliage off in say August to get good general purpose tubers. These varieties are not really late maincrops - they grow continuously all season unlike classic late maincrops which are short day length adapted. They require a different mind set - instead of working hard to get the most from them,as with other varieties, it is necessary to monitor them and stop them at the point when the tubers are right for you. Both varieties have some slug resistance (but long growing period can mask this)and both store exceptionally well. Mira is drought tolerant. Peasant survival food! Fife has been the centre of a very heavy Blue13 blight outbreak this year and only my Mira and Axona were left standing in Kettlebridge by end July!
