Royal Standard Hosta features dainty spikes of lightly-scented white tubular flowers rising above the foliage from mid to late summer. Its attractive glossy oval leaves remain emerald green in colour throughout the season. The fruit is not ornamentally significant.
Royal Standard Hosta will grow to be about 16 inches tall at maturity extending to 28 inches tall with the flowers, with a spread of 4 feet. When grown in masses or used as a bedding plant, individual plants should be spaced approximately 4 feet apart. Its foliage tends to remain dense right to the ground, not requiring facer plants in front. It grows at a medium rate, and under ideal conditions can be expected to live for approximately 10 years.
This plant does best in partial shade to shade. It prefers to grow in average to moist conditions, and shouldn't be allowed to dry out. It is not particular as to soil type or pH. It is somewhat tolerant of urban pollution. This particular variety is an interspecific hybrid. It can be propagated by division; however, as a cultivated variety, be aware that it may be subject to certain restrictions or prohibitions on propagation.
This is a relatively low maintenance plant, and is best cleaned up in early spring before it resumes active growth for the season.
