In my book, the hosta is a heaven sent plant for the gardener dealing with a shady location. For bold textures and reliability it is a plant that is hard to beat. ‘Kossa Regal’ forms a sturdy mound of powdery grey-blue leaves. The large lance-shaped leaves of this hosta are deeply veined and grow in an upright habit. Tall flower spikes of lavender flowers appear in July, but the hosta is grown primarily for its foliage.
Like other hosta varieties, ‘Krossa Regale’ appreciates humus rich, loamy soil and consistent moisture. When you plant hosta you have to be patient because it may take 2 or 3 years for it to develop into a good sized clump, but once a hosta gets established it will be worth the wait. After a certain amount of time you may want to divide your hosta and transplant the new starts. This should be done in late summer, after the flowers have faded and the foliage is beginning to look worn and tired. Do this 6 weeks before the first hard freeze occurs in your garden to allow the plants time to become established.
