1 Behind one side of my pin oak allee is my pinetum. A pinetum is an arboretum of pine trees or other conifers used for scientific or ornamental purposes.
2 The pinetum is tucked between my equipment shed and my weeping willow grove. When I first bought my farm, I knew I wanted to plant many, many trees - young trees, to replace the older ones when their lives ended. Since then, I've planted thousands of trees at my farm.
3 I started planting the pinetum about 10-years ago. All the evergreens have done so well here.
4 Recently, I added a few more specimens to the pinetum. The entire area is looking so beautiful.
5 Pines are conifer trees in the genus Pinus. There are at least 175 different varieties and subspecies of pines. Pines are evergreens, and range from dwarf size to more than 265-feet tall.
6 Dwarf pines are very hardy conifers, and thrive in nearly every zone. They also adapt well to many conditions and tolerate wind, drought and heat.
7 Spruce trees are in the genus Picea, which includes about 35-species of coniferous evergreen trees.
8 Abies, better known as firs, are a genus of nearly 60-species of evergreen, coniferous trees. They are most closely related to the genus Cedrus, or cedar.
9 Abies koreana 'Silberlocke' is a needle evergreen that grows up to 30-feet tall and spreads up to 20-feet wide. It doesn't have any flowers, but is still quite colorful - its needles are shiny dark green above and silver beneath.
10 Abies koreana 'Silberlocke', commonly called Korean Fir, is a compact, conical evergreen that grows slowly over time. It develops cones when it is young, which grow upright like other firs.
11 Abies concolor is commonly known as the white fir. This specimen adds great contrast next to all the other evergreens. It is a narrow conical conifer with a straight trunk, spire-like crown and branching all the way to the base.
12 Pinus parviflora is commonly referred to as Japanese white pine. It can reach 50 to 70 feet tall, but is usually seen in the 20 to 40 foot range. If you look closely, you can see that the bark is gray - this will change to a scaly darker gray as the tree ages.
13 Pinus parviflora cones have broad, rounded scales, and its stiff, twisted needles appear brush-like and reach about two and a half inches long.
14 Pinus parviflora cones are true pinecones, and as you can see, eventually turn woody.
15 Chamaecyparis thyoides is also known as Atlantic white cedar, Atlantic white cypress, or white cedar false cypress. Although it's called an evergreen, their foliage can be gold, yellow, lime, dark green, silvery-blue or blue-gray.
16 This is a Chamaecyparis obtusa 'Compact Fernspray'. You may know it as a hinoki cypress. It is native to Japan and features fern-like, glossy green foliage with flattened horizontal branchlets.
17 Picea orientalis 'Nigra Compacta' or oriental spruce is a medium to large, densely branched evergreen. Its needles are flattened and glossy dark green, and are shorter than the needles of other spruce species. The pinetum is filled with many different shapes and sizes of evergreens.
18 Oriental spruce, Picea orientalis 'Skylands', is slow growing, upright form that typically grows about eight to 10-feet tall over the first 10-years. The name 'Skylands' has no relation to my home in Maine - this tree was introduced by Skylands Botanical Garden in New Jersey, in 1979.
19 Picea orientalis 'Skylands' has bright yellow needles in full sun, or yellow-green needles in part shade. The yellow color typically fades as summer progresses. The interior needles are always green.
20 Here is a look at the Picea orientalis ‘Skylands’ and Picea orientalis ‘gowdy’ together - they are very similar in shape, but so different in color.
21 Pinus mugo, or mugo pine, or Swiss mountain pine, is a multi-stemmed shrub or broad-rounded small tree, which is typically very dense and grows wider than tall. It has bright green needles and scaly brown-gray bark.
22 This Thuja occidentalis 'Filiformis' is a very interesting and rather rare evergreen, which features arching sprays of fine, thread-like bright green foliage on a mounding, haystack form, reaching a height of seven to eight-feet tall. It's been in my pinetum for nearly five years and has done very well.
23 Pinus thunbergii 'Thunderhead' is a compact black pine that only grows to about 15 to 20 feet tall. It can grow upright, but with an irregular spread, and often grows wider than tall.
24 I planted this Pinus wallichiana 'Zebrina' about four years ago. It is a slow growing dwarf Himalayan pine with long, thin needles. The six to eight inch long needles form downward clusters that give the tree a feathery effect.
25 Here, you can see the many sizes of trees I've planted in this area - the Picea orientalis 'Skylands', the Picea orientalis 'Gowdy', the weeping Alaskan cedar, and in the back, the tall weeping willows.
26 Scotch pine or Picea sylvestris 'Hillside creeper' is a fast growing spreading, needled evergreen. It can grow about a foot per year. It turns a yellowish green in winter, and looks so pretty among this collection.
27 Pinus strobus 'Blue Shag', commonly known as an eastern white pine cultivar, is a dense, globose form that typically only grows to about four feet tall. Its short, blue-green needles in bundles of five are quite soft to the touch.
28 This is a Cedrus deodara 'Wells Golden' - an upright true cedar with rich, golden color, which is beautiful in winter. It can grow up to 30-feet tall.
29 Callitropsis nootkatensis 'pendula' or weeping Alaskan cedar, is a slender, strongly weeping form that grows to as much as 35-feet tall. It has widely spaced ascending to horizontal branches with flattened sprays of blue-green leaves.
30 These weeping Alaskan cedars look so graceful in the pinetum.
31 Sciadopitys verticillata 'Wintergreen' is a very unique cultivar - its needles resemble pine, but are much thicker and more glossy. 'Wintergreen' refers to its dark green color and well-branched habit.
32 Sciadopitys verticillate has umbrella-like whorls of needles. Each whorl contains about 20 to 30 soft, flattened, dark green needles that radiate outward like the ribs of an open umbrella.
33 Cyrptomeria japonica is known as Japanese cedar. It is a slender evergreen conifer with tiered horizontal branches that are slightly pendulous at the tips. It is the national tree of Japan, where it is known as Sugi.
34 This is the foliage of Cryptomeria japonica - sharply pointed, awl-shaped, green to blue-green needles in a spiral form that are actually soft to the touch.
35 Although most of the collection includes pine trees, I have included other related conifers. I just love the entire collection.
