HICKS NURSER lES, WESTBURY, L, I. 



DECIDUOUS TREES 



Elms on the Wheatley Road adjoining the property of Mr. Robert D. Winthrop. 

 Their perfect foliage in the late summer is a result of spraying with arsenate of 

 lead in May. 



ELM 

 Ulmus 



American. U. 



Americana. The 

 American E 1 m 

 will always be in 

 demand in spite 

 of the elm- leaf 

 beetle. This in- 

 sect, by the way, 

 is not nearly so 

 bad on the Amer- 

 ican Elm as upon 

 the English Elm. 

 The way to attack 

 it is not to put 

 bands around the 

 trees, but to spray 

 the trees in May 

 with arsenate of 

 lead. This sticks 

 on the foliage for 

 several months. 

 The bands kill 

 but a very small 

 per cent of the 

 beetles after they 

 have done their 

 damage. The Elm 

 will grow on any 

 part of Long Is- 

 land, but it de- 

 velops its fullest 

 beauty on deep or damp soils. Because you have pictured 

 the Elm as the highest type of landscape beauty, do not 

 think it must be the principal tree on your Long Island 

 estate. Remember that the handsome Elms you have 

 seen have been on the mainland, where the rock or clay 

 subsoils hold water near the surface, and contain more 

 mineral plant food than the washed-out Long Island sand. 



Weeping. U. Americafta, var. pendula. The Lombardy 

 Poplar is frequently recommended because it breaks the 

 monotony of round-headed trees. Here is a tree which 

 will do it in another way. Its slender branches arch out 

 lo feet from the mass of foliage in a graceful curve 

 against the sky. It makes a tall, broad tree, easy to 

 distinguish from the ordinary Elm by the curve of its 

 branches. 



GINKGO 

 Maidenhair Tree 



Ginkgo biloba; syn. Salishuria 

 adiantifolia. Here is a tree to 

 plant for posterity, for it is slow 

 to get started and, while young, 

 awkward in appearance, with its 

 narrow, ungainly limbs. It has no 

 insect or fungous enemies attacking 

 it in this climate. In this respect 

 it is unique among trees, and also 

 in the care that it takes of itself. 

 We have never seen an old tree with 

 broken branches, rotten stubs or 

 dead bark. It is a tree which gives 

 an air of distinction to the place 

 whether it is used in company with 

 other trees or singly out on the 

 lawn. There is a magnificent ave- 

 nue of them on the grounds of the 

 Department of Agriculture, Wash- 

 ington, D. C, which always attracts 

 attention. It thrives well on all 

 Long Island soils, preferring a well- 

 drained situation. 



HICKORY 



Foliage of Ginkgo showing the parallel 

 veins in the leaves different from all other 

 broad-leaved trees, which have netted veins. 



8 



Hickoria; syn., 

 Garya 

 Mocker nut. 



H. tomentosa. 

 This and the 

 White Oak, Scar- 

 let Oak, and Black 

 Oak are the rhost 

 abundant and the 

 best forest trees 

 on the largest 

 areas of Long 

 Island, that is, 

 both on the hills 

 and the Pitch 

 Pine regions. It 

 was once much 

 more common in 

 the latter, but 

 has been super- 

 seded by the Pitch 

 Pine and Scrub 

 Oak, which can 

 come in quickly 

 after fires. We 

 can show Hickory 

 trees growing wild 

 which have grown 

 faster than Nor- 

 way Maples and 

 Catalpas, planted 

 alongside. This 

 indicates that if 

 planters only get them started they will be satisfactory 

 trees. Nurserymen have not offered them because of the 

 long tap-roots and the difficulty to make them live. 

 Small Hickories should be included in mixed groups of 

 Oak, Beech and Pine, especially on the Hempstead Plains 

 and regions to the eastward. 



Shellbark, or Shagbark. H. ovata; syn., Carya alba. 

 This has nuts more easily cracked than the former, but is 

 otherwise a similar tree. It is native to Long Island only 

 on damp, clay soil, as at Cedar Swamp, near Glen Head. 



Pig Nut. Carya porcina. A Hickory partaking of the 

 gracefulness of the Elm. It is a large, full-topped [tree, 

 with slender twigs arching downward. There are trees on 

 the road from Old Westbury to Westbury Pond. 



Pecan Nut. These are from 

 seeds we obtained from the north- 

 ern part of its range in Indiana. 

 The southern Pecans are not al- 

 ways hardy. 



HORNBEAM • Carpinus 



European. C. Betulus. Here is 

 an opportunity to get a hedge for 

 service court or flower garden that 

 is different from Privet, and which 

 screens the year round with its 

 russet leaves. We offer plants that 

 have been trimmed to form hedges. 

 It is almost exactly like the Beech 

 hedges, and in Europe both Horn- 

 beam and Beech are largely used. 

 There is no reason why the same 

 custom may not be introduced 

 here. We will be very glad to do 

 all in our power to encourage it, 

 and will cheerfully welcome requests 

 for information.

 Arches. See Formal Garden Ma-
