Some of Warren's Favorite Trees, Shrubs, and Other Plants - Now Available At the Nursery

 

Anyone who has met Warren Leach and talked with him about the gardens at Tranquil Lake Nursery knows that plants are his passion. He has spent 39 creating the gardens at the nursery, where many of his favorite plants have found a home. As we wind down container sales at the nursery, we still have a limited, but choice selection of some of Warren's favorite trees and shrubs. Most are in containers -- some others are in the ground, but could be dug. Going through the nursery today, here are just some of the plants for which he has been singing the praises.

 

 

TREES AVAILABLE AT THE NURSERY

Acer negundo ‘Flamingo’, the Flamingo Boxelder Maple is a striking, colorful foliage form of the native box elder. It has received the Award of Merit by the Royal Boskoop Horticultural Society and the Award of Garden Merit by England’s Royal Horticultural Society. It is rather meritorious recognition for a humble tree often found growing in hardscrabble conditions. Despite this, Acer negundo ‘Flamingo’ is still quite scarce.

 

Flamingo’s first flush of spring leaves unfurl as an atypical coloring of pink and white. The pinnately compound leaves mature to green and white variegation with a hint of pink in the new terminal growth. The compound leaves often sport white, albino leaflets add an exotic, tropical tint. When grown in full sun the petioles are pink. It is a small tree that will flourish in sun or shade. It is easily pollarded to reduce its stature. This hard pruning promotes colorful flushes of pink growth in the summer.


An excellent accent for a mixed border of perennials and shrubs, especially with pinky-white panicles of Hydrangea paniculata cultivars, luxuriant green ferns and variegated Hosta. Its fall foliage color is yellow. Tolerates a wide range of soils, medium to wet soils. Zone 3 to 9.

Acer palmatum ‘Harriet Waldman' is a variegated foliaged Japanese maple that reaches ten to fifteen feet tall and eight to twelve feet wide at maturity. New leaves start out producing a three colored foliage of green, white, and pink. New growth in late summer makes it look from a distance like it is covered in pink flowers. Plant in dappled shade in average, well-drained soil. Mulch to shield from summer heat. A seedling of Acer palmatum 'Orodono Nishiki' discovered by Phil Waldman of Roslyn Nursery. Zone 5 to 8. (3 Gallon container - $90.)

Acer palmatum 'Harriet Waldman'  
   

Acer palmatum 'Trompenburg' is a small upright Japanese Maple tree that typically rises to fifteen-to-eighteen feet tall over ten years, eventually maturing to twenty five feet tall. Palmate leaves, seven-to-nine inches long, are deeply cut and serrated, emerge dark reddish purple with good color retention till late summer, when they fade to reddish green and bronze - and then crimson red for fall color. Red leaf stalks. Plant in full sun to part shade in moist, organically rich, slightly-acid, well-drained soil. Prefers afternoon shade. Protect from strong winds. Keep pruning to a minimum. Zone 5 to 8. (3 Gallon container - $90.)

Acer pensylvanicum commonly known as snakebark maple or Moosewood is a shrubby understory maple that is native to moist, rocky forests from Wisconsin to Quebec and south in the Appalachians to Georgia. It typically grows as a large shrub or small tree to fifteen to twenty-five feet tall (less frequently to forty feet tall) with a rounded but uneven crown that is sometimes flat-topped. This is the only species of snakebark maple that is native to North America. Key ornamental features are its interesting bark and fall color. Greenish bark on young branches and young trunks is vertically marked with distinctive white stripes (hence the common names of snakebark maple and striped maple). Stripes may vanish over time as older bark turns reddish brown.

 

Obovate, double-serrulate, three-lobed leaves (to seven inches long) emerge with pink hues in spring, mature to dark green by summer and turn bright yellow in fall. Leaf purportedly resembles a goose foot, hence the common name of goosefoot maple for this plant. Small yellow flowers (1/3” diameter) bloom in pendant racemes (to six inches long) in spring (May). Flowers give way to winged samaras (to one inch long). Moose and white tailed deer often browse the leaves and young twigs hence the common name of moosewood. Whistles can easily be carved from branch sections, hence the common name of whistlewood. Easily grown in average, medium moisture, well-drained soils in part shade. Excellent shade tolerance. Plants dislike full sun conditions. Slightly acidic, consistently moist soils are preferred. Best performance occurs in cool summer climates. Zone 3 to 7. (2 Gallon container - $32)

Chasmanthium latifolium, known as Northen sea Oats, is a clump-forming, upright, ornamental grass. Distinguished by the flat, drooping seed heads which hang in terminal clusters on thread-like pedicils from slightly arching stems. Seed heads will flutter when caressed by even the softest of breezes. Seed heads emerge green but turn purplish bronze by late summer. Bright green leaves (five to nine inches long) turn a coppery color after frost and eventually brown by winter. Excellent for dried flower arrangements. Common name of inland sea oats is in reference to the similarity of the seed heads to those of oats. Easily grown in average, medium to wet, well-drained soil in full sun to part shade. Tolerant of poor soils, but prefers moist, fertile soils. One of the more shade tolerant of the ornamental grasses. Self-seeds and may spread aggressively. Leaving foliage in place over winter adds interest to the landscape and helps protect crowns from the cold. Cut back to the ground in early spring. Native to rich woods or rocky slopes along streams and on moist bluffs in the midwest. Zone 3 to 8. (Five-pint container - $12.50)

Molinia caerulea 'Variegata’ is a compact, clump-forming purple moor grass cultivar that, as the cultivar name suggests, features variegated leaf blades (to 3/8” wide and to eighteen inches long) with creamy yellow and green longitudinal stripes. Mature plants produce profuse numbers of erect to slightly arching mid-summer flowering stalks which rise above the foliage to twenty-four-to-thirty inches tall. Each stalk being topped by a panicle (to five-to-ten inches long) of yellow-tan-purple flowers. Flower stalks have a certain transparent see-through quality. As seed sets, the flower panicles turn an attractive yellow-tan. Variegated foliage also turns yellow in fall. Easily grown in average, medium to wet, well-drained soil in full sun. Tolerates light shade, particularly, but is generally less vigorous with decreased flowering in too much shade. Unlike many of the ornamental grasses, the foliage and flower stalks of purple moor grass typically break down and fall over in late fall, providing little winter interest. Cut any surviving foliage back to the ground in early spring (late February-March) just before the new leaf blades appear. This is a slow-growing grass. Zone 4 to 9. (One Gallon container - $18.)
