Hosta Cool Mouse

Hosta 'Cool Mouse' is an exciting new sport from the hosta 'Mouse Party', introduced by the famous Belgian hosta breeder Danny Van Eechaute. This miniature hosta cultivar features thick, rounded blue-green leaves, typical of the "mouse" series, but what sets it apart is its unique variegation. Each leaf has a yellow margin with a stunning white flash where the margin meets the blue-green center, making it a truly distinctive plant in the Mouse family. The foliage forms a neat mound, growing to about 15 cm tall and 35 cm wide, perfect for small shade areas or containers.

In mid-summer, short, stout scapes hold charming lavender flowers just above the foliage, adding a splash of color. Although hosta 'Cool Mouse' is a strong grower, it is somewhat challenging to produce in large numbers, making it even more special for collectors. If you're a fan of the Mouse hostas, hosta 'Cool Mouse' is a must-have addition to your collection.

How to grow hostas

Save light shade to shade place in your garden to plant hostas. Filtered sun is best for the colorful varieties to reach their full color contrast. The green and blue hostas are the most shade-tolerant. Usually the yellow cultivars are the most sun-tolerant. The most dangerous is a direct sunshine, especially hot afternoon sun. This is the most critical where temperatures are high. Variegated varieties, especially those with a lot of white in the leaves, burn very easily. Blue color of leaves turns to green-blue or even fully green with too much direct sun. Plants with thick leaves are better suited for dry soil conditions than thin-leaved ones, but none is able to grow years-long in very dry soil. Plant hostas in moist, humus-rich soil. Water your hostas well immediately as you plant them. Give them water regularly during their first one or two growing season. Hostas grow slowly and may take 2 to 5 years to reach their full size, longer for the largest species and cultivars. Reserve a plenty of space in your perennial bed for hostas. Most of them are medium sized or large perennials. Hostas are almost fully disease and pest resistant. The most dangerous injury can by caused by slugs, snails and deers.
