  • Torreya Taxifolia
    photograph © Abraham Rammeloo Torreya taxifolia produces seeds in 40 Kalmthout Arboretum ABRAHAM RAMMELOO, Curator of the Kalmthout Arboretum, writes about this rare conifer that recently produced seed for the first time. Torreya is a genus of conifers that comprises four to six species that are native to North America and Asia. It is closely related to Taxus and Cephalotaxus and is easily confused with the latter. However, it is relatively easy to distinguish them apart by their leaves. Torreya has needles with, on the underside, two small edges with stomas giving it a green appearance; Cephalotaxus has different rows of stomas, and for this reason the underside is more of a white colour. It is very rare to find Torreya taxifolia in the wild; it is native to a small area in Florida and Georgia. It grows in steep limestone cliffs along the Apalachicola River. These trees come from a warm and humid climate where the temperature in winter occasionally falls below freezing. They grow mainly on north-facing slopes between Fagus grandifolia, Liriodendron tulipifera, Acer barbatum, Liquidambar styraciflua and Quercus alba. They can grow up to 15 to 20 m high. The needles are sharp and pointed and grow in a whorled pattern along the branches. They are 25 to 35 mm long and stay on the tree for three to four years. If you crush them, they give off a strong, sharp odour.

Because economic profit takes priority over environmental cost, increasing amounts of fertilizer have been used in mature subtropical Torreya grandis orchards. However, given the magnitude of global nitrogen deposition, it’s worth considering whether heavy fertilizer treatment is necessary. To elucidate the balance between T. grandis nutrient demands and fertilizer supply, we determined the C, N, and P concentrations of foliar and soil ([C], [N], [P]) at 9 orchards undergoing long-term fertilizer treatments in two scenarios of N and N + P addition with Citation: Han, Y.; Wang, G.G.; Wu, different intensity.

    ​ The Trees of Seattle University 1 Table of Contents Introduction . 3 Kubota’s Legacy . 4-17 Ciscoe’s Legacy . 18-27 Exceptional Trees . 28-34 References . 35 2 Introduction I have lived on Seattle U campus for four years and have grown to deeply admire and respect the many wonderful trees and plants on campus in my time here. I was invited to intern with Grounds to create this biography through the mentorship of Janice Murphy and Shannon Britton; it was gratifying and exciting to be able to use the knowledge I’ve gained in my time here to help add to the depth of the beautiful garden that is the Seattle University campus. I hope that this biography serves as a resource for anyone looking to become more acquainted with the flora on campus, and that my photography portrays the trees in a way that does them justice. The Trees of Seattle University campus map was designed and illustrated by A​ lyssa Lau​, a Seattle University graduate in the class of 2018. Alyssa created the map to use her graphic design skills to promote education about the biodiversity on campus. Alyssa also created all of the tree drawings on the map, she did them by hand with colored pencil to capture the organic nature of the trees. Fujitaro Kubota​ was a legendary Japanese landscaper who emigrated to the United States in 1907 and worked on the Seattle U campus in the late 1950s and ‘60s. His family business, the Kubota Gardening Company, is still operating today and the garden headquarters can be visited in Renton, WA.

  • Tree Planting and Management
    COMMONWEALTH WAR GRAVES COMMISSION Tree Planting and Management Breadth of Opportunity The spread of the Commission's responsibilities over some 148 countries in temperate, mediterranean, tropical and desert climates provides wonderful opportunities to experiment with nature's wealth of tree species. We are particularly fortunate in being able to grow many interesting and beautiful trees and we will explain how we manage them and what splendid specimens they can make. Why Plant Trees? Trees are planted for a variety of reasons: their amenity value, leaf shape and size, flowers, fruit, habit, form, bark, landscape value, shelter or screening, backcloth planting, shade, noise and pollution reduction, soil stabilisation and to encourage wild life. Often we plant trees solely for their amenity value. That is, the beauty of the tree itself. This can be from the leaves such as those in Robinia pseudoacacia 'Frisia', the flowers in the tropical tree Tabebuia or Albizia, the crimson stems of the sealing wax palm (Cyrtostachys renda), or the fruit as in Magnolia grandiflora. above: Sealing wax palms at Taiping War Cemetery, Malaysia with insert of the fruit of Magnolia grandiflora Selection Generally speaking the form of the left: The tropical tree Tabebuia tree is very often a major contributing factor and this, together with a sound knowledge of below: Flowers of the tropical the situation in which the tree is to tree Albizia julibrissin be grown, guides the decision to the best choice of species. Exposure is a major limitation to the free choice of species in northern Europe especially and trees such as Sorbus, Betula, Tilia, Fraxinus, Crataegus and fastigiate yews play an important role in any landscape design where the elements are seriously against a wider selection.

  • Magnolia Obovata
    ISSUE 80 INAGNOLN INagnolla obovata Eric Hsu, Putnam Fellow, Arnold Arboretum of Harvard University Photographs by Philippe de 8 poelberch I first encountered Magnolia obovata in Bower at Sir Harold Hillier Gardens and Arboretum, Hampshire, England, where the tightly pursed, waxy, globular buds teased, but rewarded my patience. As each bud unfurled successively, it emitted an intoxicating ambrosial bouquet of melons, bananas, and grapes. Although the leaves were nowhere as luxuriously lustrous as M. grandrflora, they formed an el- egant wreath for the creamy white flower. I gingerly plucked one flower for doser observation, and placed one in my room. When I re- tumed from work later in the afternoon, the mom was overpowering- ly redolent of the magnolia's scent. The same olfactory pleasure was later experienced vicariously through the large Magnolia x wiesneri in the private garden of Nicholas Nickou in southern Connecticut. Several years earlier, I had traveled to Hokkaido Japan, after my high school graduation. Although Hokkaido experiences more severe win- ters than those in the southern parts of Japan, the forests there yield a remarkable diversity of fora, some of which are popular ornamen- tals. When one drives through the region, the silvery to blue-green leaf undersides of Magnolia obovata, shimmering in the breeze, seem to flag the eyes. In "Forest Flora of Japan" (sggII), Charles Sargent commended this species, which he encountered growing tluough the mountainous forests of Hokkaido. He called it "one of the largest and most beautiful of the deciduous-leaved species in size and [the seed conesj are sometimes eight inches long, and brilliant scarlet in color, stand out on branches, it is the most striking feature of the forests.
