Hosta 'Captain Kirk' Overview

Hosta 'Captain Kirk' is a mound-forming perennial cultivar with leaves that appear chartreuse yellow-green through to a golden-yellow shade, then to ivory with margins of a darker green. In mid to late summer erect stems with nodding lavender flowers appear. All Hostas need some shade, and few will thrive in strong sunlight. A general rule is that the lighter 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 also 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, and 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 a necessity and any good garden soil - unless very alkaline - is fine.
