'Vanderwolf's Pyramid', Limber Pine

Pinus flexilis

‘Vanderwolf’s Pyramid’ limber pine is an evergreen tree with a pyramidal habit that typically grows 20-30 feet tall and about 10-15 feet wide. The specific epithet and common name is in reference to the flexible (limber) branchlets/twigs. ‘Vanderwolf’s Pyramid’ is noted for its closely spaced, twisted, silvery blue green needles. Limber pine is generally considered to be an adaptable, low-maintenance tree with few problems. Limber pine is native to North America and is considered resistant to pine wilt disease.

Shrub for 2019

Double Take series, Flowering Quince

Chaenomeles speciosa

Flowering quince in the Double Take™ series are hardy, deciduous shrubs reaching 4 to 5 feet high and at least as wide. Plants in the Double Take™ series produce a profusion of early spring double flowers that resemble camellias. This is a dense, broad-rounded, thornless, shrub. Bold double flowers (to 2” diameter) bloom before the leaves fully unfold in an early spring bloom and come in colors of scarlet, orange, pink, and peach. Plants do not produce fruit. Oval to oblong, glossy dark green leaves provide an attractive look through the summer. Prune lightly after blooms in spring when needed. Double Take™ flowering quince is very drought tolerant once established.

  • Exposure: Sun to part shade
  • Soil: tolerates wide variety of soils, but prefers well-drained.
  • Hardiness: USDA Zones 5-9.

 

 

 

Perennial for 2019

Rattlesnake Master

Eryngium yuccifolium

Rattlesnake Master is a native species to the tall grass prairies. Leaves of rattlesnake master are parallel-veined, bristly-edged, sword-shaped, medium green leaves (to 3' long) resembling those of yucca. Flowers are greenish-white and tightly packed into globular, 1" diameter heads resembling thistles. The flowering heads attract many kinds of insects

Rattlesnake master prefers dryish, sandy soils, but tolerates clay and shallow-rocky soils. Plants tend to open up and flop in overly fertile soils or in anything less than full sun. This is a taprooted plant which transplants poorly and is best left undisturbed once established.

Use rattlesnake master in a xeriscape garden, perennial border, or native garden. Group plants in naturalized areas for best affect.

  • Exposure: Sun, part shade
  • Soil: Tolerates about any soil
  • Hardiness: USDA Zone 4-10

 

 

 

Annual for 2019

Graffiti® series, Star Flower

Pentas lanceolata

Considered to be the most uniform in habit as well as bloom time, Graffiti® comes in several colors, pink, purple, bright red, rose and white and grows to 16 inches high and 12 inches wide making it a great plant for containers or in a flower bed.

Graffiti® plants are very heat- and drought-resistant and make great cut-flowers. With its tightly clustered flowers that sit above the foliage in bright colors that have an abundance of nectar, Graffiti® pentas are a sure attractant for butterflies and hummingbirds throughout the summer months.

Like all Pentas, Graffiti® prefers soil that is not too rich; if it's a bit on the dry side, all the better. Heat, sun, and good drainage will have the plants blooming heartily all summer long.

  • Exposure: Full sun to part shade
  • Soil: Moderately moist, well-drained soil
  • Hardiness: Use as an annual
