Cut back the foliage of Myosotis scorpioides 'Alba' once first flowering is over and you may get a second flush of flowers later in the season. Myosotis stems go black in winter but leave these under the water as fresh shoots will appear along their length in Spring. Myosotis scorpioides species encourage wildlife as it gives plenty of habitat opportunities - newts in particular make use of Myosotis leaves for laying their eggs. As a rafting plant that is allowed to grow freely it will use plenty of surplus nutrients so help to keep pond or container water free from algae.
