About the genus

Myosotidium is a genus of plants belonging to the family Boraginaceae. This genus is represented by the single species Myosotidium hortensia, the Chatham Islands lily, giant forget-me-not or Chatham Islands forget-me-not, which is endemic to the Chatham Islands, New Zealand.

In the garden

Myosotidium hortensia is a single-species member of the Boraginaceae and originates from the Chatham Islands. Gardeners prize it for planting where a coastal influence is present; its provenance means it performs well where conditions are tempered by sea air and shelter. It is treated as a perennial herb in cultivated borders and coastal schemes. Position plants where they receive partial shade to full sun, provided the soil remains moist and fertile; heavy but well‑drained soils suit it better than dry, free‑draining planting sites. Give the root area consistent moisture while avoiding waterlogging; a sheltered aspect reduces wind stress and salt scouring on the leaves. Use Myosotidium hortensia as an ornamental specimen in coastal gardens, sheltered borders or beside paths where its summer flowers can be appreciated at close range. In the UK its main display runs from June to August, making it useful for adding seasonal interest to seaside and sheltered garden plots.
