Hosta 'Smiling Mouse' Overview

Hosta 'Smiling Mouse' is a hardy perennial cultivar that forms mini to small mounds of variegated grey-green leaves with ruffled creamy-white borders. In mid to late summer, erect stems of pale-lavender flowers appear. All Hostas need some shade, and few will thrive in strong sunlight. A general rule is that the lighter the foliage, the brighter the sunlight that will be tolerated. Variegated varieties tend to require more sun to keep their white, light green or gold stripes. The darker, bluer varieties need more shade. They are ideal for growing in North facing aspects of your garden where most other plants would struggle. Once established, Hostas are pretty tough and will spread horizontally to make an excellent ground cover. They are suitable for most garden styles and look good in containers (but keep well watered and watch out for vine weevil in pots!). They require little care apart from tidying up spent leaves and flowers at the end of the growing season, preferably an autumn mulch. Also, in spring, to retain moisture. Hostas like a sheltered position in moist, well-drained soil and do best in a slightly acidic growing medium, but this isn't necessary. Any good garden soil - unless very alkaline - is fine.

How to propagate Hosta 'Smiling Mouse'

Division

Divide clumps every 4 or 5 years in late summer or early spring. Ensure each section has 1 to 3 good buds and trim away damaged roots. Replant at their original depth in the ground with the shoots just poking through the soil. Water and apply a granular feed.

Seed

Collect seeds in autumn from dry seed heads, sow in spring and place in a cold frame. Seeds are unlikely to come true.
