The King Ostrich Fern's attractive fragrant ferny compound leaves remain light green in colour throughout the season. Neither the flowers nor the fruit are ornamentally significant.
The King Ostrich Fern will grow to be about 6 feet tall at maturity, with a spread of 4 feet. When grown in masses or used as a bedding plant, individual plants should be spaced approximately 3 feet apart. It tends to be leggy, with a typical clearance of 1 foot from the ground, and should be underplanted with lower-growing perennials. It grows at a fast rate, and under ideal conditions can be expected to live for approximately 20 years.
This plant does best in partial shade to shade. It is an amazingly adaptable plant, tolerating both dry conditions and even some standing water. It is not particular as to soil pH, but grows best in rich soils. It is highly tolerant of urban pollution and will even thrive in inner city environments. 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 high maintenance plant that will require regular care and upkeep, and is best cleaned up in early spring before it resumes active growth for the season. Deer don't particularly care for this plant and will usually leave it alone in favor of tastier treats. It has no significant negative characteristics.
