Tree for 2006

‘Prairifire’ Crabapple

Malus 'Prairfire'

Few trees have as much year-round interest as the crabapple and few crabapples are as beautiful and disease resistant as ‘Prairifire’. ‘Prairifire’ starts the spring with a profusion of rose-pink flowers just as the leaves emerge. As summer progresses the leaves turn from purple-red to dark green and red fruit forms that persist well into the winter. The diseases that affect many crabapples don’t phase this tree and its rounded crown, which will not exceed 20' tall, makes it a perfect choice for planting under utility lines or in masses.

  • Exposure: Full sun
  • Soil: Well-drained
  • Hardiness: USDA Zone 4

 

 

 

Shrub for 2006

Diabolo® Ninebark

Physocarpus opulifolius 'Monlo'

Diabolo® is a cultivar of ninebark prized for its deep maroon foliage, which contrasts nicely with the clusters of white flowers produced in the spring and is a great companion for gold or chartreuse-leaved plants. This deciduous shrub grows from 6' to 10' high and wide but can be rejuvenated by pruning it to the ground in winter. Red fruit extends ninebark’s show into the fall and exfoliating bark adds winter interest. Diabolo® is a hardy and durable shrub that can be used as a screen, for massing, or at the back of a border.

  • Exposure: Full sun to part shade
  • Soil: Tolerant of acid, alkaline, or dry soils
  • Hardiness: USDA Zone 2

 

 

 

Perennial for 2006

'Golden Jubilee' Anise Hyssop

Agastache foeniculum 'Golden Jubilee'

‘Golden Jubilee’ is a cultivar of the North American native commonly known as anise hyssop. It was selected for its chartreuse foliage, was named to commemorate HM Queen Elizabeth II’s golden jubilee, and was the 2003 All-America Selections flower award winner. Reaching 2' tall and 1' wide, ‘Golden Jubilee’ produces light purple flower spikes from early summer to fall. Although a perennial, it will reseed in your garden and the new plants will also be golden. As an added bonus, brushing against the foliage releases the plant’s licorice scent.

  • Exposure: Full sun
  • Soil: Moist, well-drained
  • Hardiness: USDA Zone 6

 

 

 

Annual for 2006

Wishbone Flower, Summer Wave™ Series

Torenia fournirez

The Summer Wave™ Series is a collection of hybrid Torenia, or wishbone flowers, that thrive in the summer heat. The plants form a 6" high by 12" wide mound that is great for the border, in a pot, or mixed with other plants in a larger container. The Summer Wave™ Series is comprised of the following cultivars: ‘Amethyst’, ‘Blue’, ‘Large Violet’, and ‘Lavender Blue’. Each produces flowers from spring until fall, and each flower has a wishbone at its center, thus the name.

  • Exposure: Partial shade
  • Soil: Moist, well-drained
  • Hardiness: Use as an annual
