'Allegiance' Daylily, Perennial Of The Day

Hemerocallis x 'Allegiance' Daylily


Type Perennial
Hardy range 4A to 10A

Spread 18" to 24" / 45cm to 60cm
Growth rate Average
Form Irregular or sprawling
Exposure Partial shade or partial sun
Bloom Color Red
Bloom Time Summer


Environment
This plant tolerates drought. This plant will grow in moist soil. Suitable soil is well-drained/loamy. The pH preference is a neutral soil. 

Leaf Color Green
Fall Color No change in fall color

This plant has attractive foliage.
The flowers are suitable for cut flowers.

Culture Notes
Plants are best placed in a location that receives morning full sun but some shade from the afternoon sun. Many cultivars also tolerate full sun, especially in the northern part of their hardiness range. Heavy shade produces lots of foliage but few flowers.
This plant tolerates a wide range of soil conditions but most enjoy a soil with ample organic matter. Before planting, be sure to loosen the soil in as large an area as possible. They tolerate some drought but perform best with irrigation in dry weather.
Plant about 18 inches apart and do not place too deep. The white part of the foliage should be just at the soil line. Add about 2 inches of mulch to help preserve soil moisture. A slow release fertilizer can be incorporated into the planting holes to help plants regain vigor quickly. Apply about 2 fertilizations yearly during the growing season to maintain vigor. Do not apply too much nitrogen as this can encourage lots of foliage growth with few flowers.
Many daylilies loose vigor and flower poorly 3 to 4 years after planting if they become too crowded. Divide the clumps in early spring or at least one month before frost in the fall. Do not expect flowering to be spectacular the first season after dividing.

Pests, Diseases and Damaging Agents Aphids are the biggest potential problem but are usually not terribly serious.

Maiden Grass, Perennial Grass Of The Day

Environment This plant tolerates some drought and occasional wetness. This plant will grow in moist to wet soil. Suitable soil is well-drained/loamy, sandy or clay. The pH preference is an acidic to slightly alkaline (less than 6.8 to 7.7) soil.

Leaf Color Green and variegated
Fall Color Brown, copper and orange 

This plant has attractive foliage and attractive fall colors.
The flowers are showy, suitable for cut flowers and suitable for dried flowers.
Culture Notes Maiden Grass is a gracefully arching, fine-textured grass that forms dense, green clumps. Slender leaves originate in a clump, spreading out and up like a fountain. The 5 to 6-foot-tall clumps bear pink flowers in late summer and fall which can be used for drying or as a dye plant. Their pinkish or silvery 8- to 10-inch-long plumes persist into the winter. Foliage is flexible and blows easily in the wind. This shrub-like grass turns to a rich gold in the fall; the fall color lasts through the winter.
Maiden Grass is frequently used in the landscape as a specimen or screen. It is also employed in group plantings forming a nice mass of fine-textured foliage, especially near a water garden or pond. Use Japanese Silver Grass as an accent or mass planted in a large-scale landscape, such as around a commercial building to add a touch of soft elegance and texture. The slightest breeze moves the foliage allowing the landscape to `come alive'.
Maiden Grass requires a location in the landscape that receives full sun, but it is adaptable to most well-drained soils. This ornamental grass is quite drought tolerant. Miscanthus sinensis is a warm season grass and transplants best in the spring. Provide good drainage at the planting site. Three- and four-year-old plants tend to flop over and might thin in the center of the clump. They can be divided or cut back to encourage more upright growth.
Miscanthus will go dormant to the roots during the winter. The old foliage should be removed from the plants in the spring. This allows the new growth to come through unimpeded.
Cultivars include: `Condensatus', coarser leaf texture than species, mid-summer bloom, 7 to 8 feet tall; `Gracillimus', narrower leaves than species, Fall bloom, upright growth habit from 5 to 8 feet tall; `Purpurascens', reddish foliage in summer, purple-red foliage in fall, silver pink inflorescence, mid-summer bloom, 4 to 5 feet tall; `Silver Feather', silvery white flowers in mid-summer; `Strictus', horizontal yellow bands on foliage, upright growth habit, 6 to 8 feet tall; `Variegatus', white variegation on leaf margin, does relatively well in partial shade, to 7 feet tall; `Yaku Jima', more compact, 3 to 4 feet tall; `Zebrinus', horizontal yellow bands on foliage, wide spreading habit, to 7 feet tall.
Pests, Diseases and Damaging Agents Diseases: Rust occasionally infests the foliage but it often goes away in drier weather.
