There is a large group of Meconopsis that are evergreen with rosettes that gradually become larger as the years pass. These usually flower at 3, 4 or even 5 years and then a flowering spike arises from the centre and usually reaches several feet as the flowers open.

 They then die and are thus what is known as monocarpic. These plants are clearly hybrids and thus it is better to write M. 'napaulensis' Under the new classification by Chris Grey-Wilson M. napaulensis is a relatively short yellow flowered monocarpic species from a restricted area in the Himalayas.
