Daylily, Monster Daylily
This entry has yet to be reviewed and approved by L2G editors.
Not scary like a monster, but monstrous in size, the yellowish flowers of the Monster daylily are a grand showpiece in the garden! This cultivar blooms in late mid-spring to very early summer, depending on climate. The daylily is a popular perennial revered for its reliability, ease of growth and floral beauty. The hybrid tetraploid 'Monster' was bred by George Pettus and introduced in 1975.
This daylily produces numerous 9-inch-wide (23 cm) flowers atop a branching naked stem called a scape. Each petal-like tepal is narrow and pointed, creating a star-like flower head. The green throat helps bring out the subtle light green undertones in the overall lemony yellow blossoms. The scapes rise from clumps of strappy green leaves that die away each winter. Each blossom in the bud cluster opens in the morning but shrivels up well before reaching 24-hours old.
Daylilies are clump-forming and spread slowly via rhizomes. The blooms are commonly held in branched clusters on long leafless stems that stand above the foliage. All daylilies are easy to grow if provided full to partial sun and average soil with good drainage. Deciduous daylilies are the hardiest and survive in the coldest reaches of their range; however they may struggle in areas with mild winters. Evergreen types grow well in all but the most tropical regions but require protection where winters are harsh and cold. Their clumps spread over time and may need to be divided every three to four years. After plants bloom, it is wise to shear back their foliage to allow for a fresh flush of growth.
