This miniature Hosta hybridized by Tony Avent has a similar leaf shape and performance to ‘Blue Mouse Ears’, but with brilliant yellow leaves that holds its yellow color well into summer. The color is perfect for brightening up hosta troughs and shade gardens. Compared to ‘Blue Mouse Ears’, ‘Sun Mouse’ is a little bit shorter and wider. Plant it in an area with morning sun or filtered shade for best yellow color. Lavender flowers appear in midsummer.
Hostas are exceedingly popular perennials in today's gardens due to their versatility in the landscape. Hostas also grow well in city environments where the air may be polluted by car exhaust, etc.
Hostas grow best in moist, well-drained, highly organic soils with a pH between 5.5 and 7.5. Sandy loam is better than clay because it provides more aeration for the roots. High-filtered or dappled sunlight is necessary for clean, healthy growth. Morning sun is tolerable and will help to intensify the leaf colors, but hot afternoon sun is usually deadly to hostas. They are most at home in shady, woodland settings and often work well as specimen or edging plants.
Especially in northern zones, hostas should be mulched with a layer of finely shredded organic material to prevent heaving in the winter. Mulch is beneficial because it retains moisture around the plant's roots, but it is also the ideal place for slugs to hide. Watch for holes in the center of the leaves. If they are present, so are slugs. Applying a slug bait in early spring when new shoots are beginning to emerge will help to reduce the slug population. After a few years when plants are firmly established, the mulch can be removed completely, which should eliminate the slug problem altogether. Also be sure to clean all hosta foliage out of the garden in early winter after the plants have gone dormant. By doing so, you will be ridding the area of the eggs of slugs and other leaf-eating insects.
