'Conica' |
The
dwarf Alberta spruce may well be the most popular dwarf conifer
in cultivation. The basic conifer for your home landscape. Excellent
subject for a wide range of topiary forms. This conical plant with
fine, dense, grass-green foliage was found by Prof. J.G. Jack and
Alfred Rehder of the Arnold Arboretum in 1904 at Lake Leggan, Alberta,
Canada. |

| Picea glauca 'Hobbit' |
This short, plump selection of Picea glauca 'Conica' exhibits the same likeability as its namesake, Bilbo Baggins from JRR Tolkien’s The Hobbit. Like Baggins, the small, reliable White Spruce is half-size, well behaved and hard working. Tiny green needles on upright branches give the globose young ‘Hobbit’ charm and contribute to its appeal as it matures into a wide cone. Provide ample moisture for this adaptable cultivar discovered at Iseli Nursery. |

| Picea glauca 'Humpty Dumpty' |
The habit of this extremely dense, Alberta-type plant explains it name: short and plump, kind of egg-shaped, like Humpty Dumpty. With nearly equal base width and height, it forms an almost perfect pyramid that is only 2/3 the size of ‘Conica.’ Found as a witch’s broom and introduced by Iseli Nursery. |

'Jean's
Dilly'® |
An
extraordinary dwarf form of the popular dwarf Alberta spruce. 'Jean's
(pronounced John's) Dilly'T grows at only one-half to two-thirds
the rate of dwarf Alberta spruce, making it a perfect accent for
small to moderate-sized landscapes. It's also an absolute gem for
rock garden, container garden or perennial border. Perfect shape,
slow growth, lovely texture and color, combine to create a remarkable
little plant that will never outgrow its place in your garden. |

| Picea glauca 'North Star' |
Selected for its resilience to harsh winter conditions, this sturdy, compact White Spruce produces a densely branched, classic pyramid that is covered with medium-green needles. Its moderate growth rate and ultimate, intermediate size, together with superior hardiness make this introduction from Iseli Nursery ideal for use in larger, more exposed spaces, mixed borders and beds. |

'Pendula'
|
An
outstanding weeping selection and a notable example of an old clone
which needs to be rediscovered. Distinctive in its very formal habit,
yet very pendulous with stiffly held, downward-hanging branches,
heavily covered with soft, light grey-green needles forming a narrow,
conical shape. Discovered in a native stand in Guelph, Ontario. |

This
Alberta selection is a suitable accent for landscape, border or
container planting. Needles are short, dark-green with a slight
blue-green cast. Extremely dense, very compact growth rate compared

An exceptional addition to any garden. |

'PixieDust' |
Extremely dense, compact and slow growing, this almost-miniature selection resembles 'Conica' in form, but offers a special feature. When the second flush of growth emerges in summer, the new tips are yellow, a surprising effect that contrasts dramatically with the deep-green, mature foliage. Chosen by the American Conifer Society as 2006 Collector's Conifer of the Year, this adaptable cultivar produces a magical effect in trough, container or rock garden. Provide ample moisture and full sun for the best color on this sport of 'Pixie' that was discovered at Iseli Nursery. |

'Rainbow's End'® |
Whoever
believes conifers lack seasonal color interest has never seen 'Rainbow's
End'. Comparable to Picea glauca 'Conica' except for color. In spring,
the new growth is light green, nothing out of the ordinary. In mid-summer,
the second flush is nothing but extraordinary. Bright, creamy-yellow
new growth contrasts dramatically against the dark-green older foliage.
Mutation found at Iseli Nursery in 1978. |

foliage. Blends well with all conifers and perennials for companion
and foundation planting or as a novel focal point. |
