GARDENING. 



Mar. 



ered varieties j'ou must surely get. As 

 double-flowered sorts get Mme. Lemoine, 

 white; President Grevy, bluish; Lamarck, 

 rosy lilac, and Maxime Cornu, lilac rose. 

 Don't omit some Persian lilacs, say the 

 white Persian, and Rothomagensis rubra. 

 Villosa is a late-flowering species with 

 dense panicles of pale rose-purple flowers, 

 distinct from other lilacs. If rosebugs 

 are not very numerous in your part of 

 the country, get the tree lilac (Syringa 

 Japonica), and the Chinese lilac (S. Pekin- 

 ensis); they have large panicles, often 

 compound, of white, fleecy-like flowers 

 after the common lilacs are all past. But 

 if you are in a rosebug country the bugs 

 will infest and destrov the blossoms. 



THE SUGI OR JAPAN CEDAR TREE. 



( Cryp tomeria Japonica) . 



Our illustration, engraved from a pho- 

 tograph, shows a pretty little plant of 

 the Sugi treeof Japan growing at Dosoris. 

 Behind it stand some fine old red cedar 

 (Juniperus Virginiana) trees. The cryp- 

 tomeria is an evergreen conifer with a 

 general contour remainding one of the 

 big trees (Sequoia) of California, and in 

 favorable localities becomes a striking and 

 handsome garden tree. It seems to be 

 perfectly hardy on Long Island, and 

 flourishes south of New York, but north 

 of here if away from the sea coast it is 

 not reliably hardy. To have it appear in 

 its finest form it should have good moist 

 loamy soil and a sheltered position and it 

 is well worth such care. In its native 

 country it is largely planted in gardens 

 and temple grounds and in forests, where 

 mature specimens with trunks -t feet or 

 over in diameter rise to a height of 100 to 

 125 feet. In cultivation in our gardens 

 there are several varieties of it, the com- 

 monest being the dwarf one called nana, 

 the Dosoris specimen of which doesn't 

 grow six inches in height in a year, but it 

 keeps dense and healthy, and seems to 

 be as hardy as the type. 



Cryptomeria elegans, another but more 

 Southern Japan species, is not hardy with 

 us. It is, however, hardy in the south, 

 and to be found in lovely perfection in the 

 gardens of Southern Europe. Here it is 

 grown as a cool greenhouse tree, or it is 

 planted out of doors in summer and lifted 

 and housed in a pit over winter as we do 

 with sweet bay laurels, fancy hollies, etc., 

 while of a beautiful soft green shade in 

 summer, in winter it assumes a bronze- 

 brown tint just as do Retinospora eri- 

 coides, Douglas golden juniper or Chinese 

 golden arbor vitie. 



DOUBLE-FLOWERINO SLOE-FERTILIZER. 



Naples, Long Island City, asks as fol- 

 lows; 



DOUBLE-FLOWERINO Sloe (Pruniis spi- 

 nosa B. pi.) — "Should it be prtined, and if 

 so, how much and when?" 



Ans. It isn't extra vigorous and all the 

 pruning, if any, it needs is to keep it in 

 comely shape. Don't prune it unless it 

 becomes unshapel3', for the more j^ou 

 prime it the less it will bloom. If pruning 

 is needed, do it now. 



Fertilizer for Siirubberv. — What 

 should be used as such and when? 



Abs. a compost of stable manure 

 (chiefly cow manure, if available) and 

 field loam, about half of each. A heavy 

 dressing of stable manure alone will also 

 do good, A dressing one-fourth inch 

 deep of wood ashes will help the bushes. 

 Ii you prefer a chemical fcrtiliger, use a 

 "complete manure," but be very careful; 

 use it under ra tlier ilinn over the allow- 

 ance given in printed directions givenyo« 



by the agent from whom you buy the 

 manure. 



ViTis CoiGNETi.E.— A reader writes: "I 

 have an outside chimney 30 feet high and 

 6 feet wide which I desire to have covered 

 with a vine, and 'I feel it in my bones' 

 that this is the proper vine for the pur- 

 pose. What say you? Awpelopsis 

 FeitcA// isn't quite hardy with us and I 

 don't want the Virginia creeper. Can 

 you recommend any other selfclinging 

 vine that would cover it?" 



Ans. Veitch's ampelopsis not being 

 sufficiently hardy with you, we know of 

 no self-clinging vine thatwill answeryour 

 purpose. While we have great faith in 

 Vitis Coignetiie and have planted it at 

 Dosoris, it is so new with us that we 

 know very little about its behavior here. 



J.vp.\N Allspice. — In answer to H., St. 

 Louis: The botanical name of it is Chi- 

 monanthus fragans. The folks you sent 

 to for it and who didn't know it should 

 look into Dr. Asa Gray's Field, Forest 

 and Garden Botanv. 



Rose Bradwardine.— Clear rose, good 

 shape, plant of robust habit and profuse 

 bloomer.

LORD PENZANCE'S flYBRlD BRIAR ROSES. 



I am getting a set of Lord Penzance's 

 hybrid sweet briars; am puzzled to find a 

 place for them. Will they thrive where 

 they get the sun up to say 11 a. m ? After 

 then would be in the shade? li. 



Northern Illinois. 



So far as the situation as regards sun- 

 shine is concerned, providing there is no 

 overhead shade like the branches of trees, 

 we should think it was all right, but as 

 these hybrid briars are new to us and our 

 experience with them is so limited we 

 cannot speak authoritatively in reference 

 to their success in our gardens. True, their 

 mother the sweet briar is hardy enough, 

 but as we are not so sure of all of their 

 pollen parents, we must test them before 

 we can vouch for their hardiness. The 

 following notes on these roses are from a 

 reliable English catalogue just to hand, 

 but there is no need of sending to Europe 

 for them. John Saul and some other of 

 our nurserymen have a stock of them: 



Hybrid Sweet Briars.— Raised by the 

 Right Hon. Lord Penzance from the com- 

 mon sweet briar crossed with various old 

 garden roses, the Austrian briar, etc. 



Amy Robsart.— a true briar of robust 

 habit and very free blooming. Flowers 

 deep rose, very beautiful in bud. 



Anne of Geierstein.— Dark crimson 

 succeeded by clusters of bright red hips. 



Brenda. — Maiden's blush or peach color 

 greatly relieved by the bright golden ant- 

 lers. 



Flora MacIvor.— Flowers white faintly 

 tinted with light rose, large and very use- 

 ful for cutting when associated with the 

 handsome foliage of the plant. 



Lady Penzance.— Flowers of peculiar 

 and distinct color; the base of the petals 

 is 3-ellow, the remainder coppery red with 

 metallic lustre. Both flowers and foliage 

 very fragrant; habit vigorous and sub- 

 pendulous. 



Lord Penzance.— Soft shade of fawn 

 or tawny yellow passing into bright yel- 

 low at the center, sometimes toned with 

 pink; very floriferous and sweet scented. 



Lucy Ashton.— White edged with pink, 

 very free flowering, erect habit and frftr 

 grant foliage.

Black Spot on Roses.— J. J. DeL., Clo- 

 quet, Minn., writes: "I send you some 

 rose leaves. Please tell me what is the 

 matter with them and what I should do 

 to stop it?" 



.4ns. The trouble is black spot, a com- 

 mon and very destructive fungoid disease 

 t chnicallj' known as Actinonenta Rosa^. 

 Any uncongenial cultural or climatic con- 

 dition may cause it — for instance, pro- 

 longed damp dull weather, sudden chills, 

 a sodden soil, a raw, close, damp atmo- 

 sphere, inattention to ventilation, etc. 

 Prevention consists in close attention to 

 the^aest cultural details, including rigid 

 cleanliness and the picking off of every 

 spotted and fading leaf Dr. Byron D. 

 Halsted, our cry ptogamic authority, says: 

 "This trouble may be held in check by the 

 carbonate of copper compound, using 

 three ounces of the carbonate of copper, 

 one quart of ammonia and 50 gallons of 

 water. Spray once a week, using a hose 

 and a nozzle that gives a fine spray. The 

 point should be to wet every part of the 

 plant and yet not drench it. If many 

 leaves have fallen from the plant they 

 should be gathered up and burned." But 

 without the strictest attention to cultu- 

 ral details spraying will avail one verv 

 little. 



Rosa grandiflora. — C. W. asks: 

 "Should th'S rose be trained to a pillar? 

 Ho^ high does it grow?" Ans. Itisnot 

 a pillar rose, rather, it forms a bushy 

 plant 2 to 3 feet high and as much or 

 more thorough, but with age we should 

 expect it to add a foot ortwo more to its 

 stature and more than that to its spread 

 of branches. 



Aquatics. 



WATER LILIBS. 



"How ranch space is needed by the 

 Nywphwa odorata? How much by the 

 Nelambiuw speciosum? How can a water- 

 tight tank large enough for one nelnm- 

 bium and a half dozen nympha;a be con- 

 structed? Is a tub or tank for growing 

 water lilies likely to become a breeding 

 places for mosquitoes? A. D. M. 



.4ns. Get a gasoline or wine barrel and 

 saw it across through the middle, making 

 two equal-sized tubs from it; then out in 

 the back yard start a little fire of a few 

 sticks or shavings and turn the tubs, one 

 at a time, over that for a minute or two 

 to burn out the uncleanness; to put out 

 the fire in the tub, turn the tub over on 

 its mouth on the soft ground, drawing a 

 little earth around the edges to smother 

 the fire. Now, with plenty water and a 

 stiff broom scrub them clean. Put two 

 to three inches deep of clean rubble in the 

 bottom of the tubs and a thinly peeled 

 sod, grass side down over that to keep 

 the rubblefree from dirt; then fill the tubs 

 two-thirds full with a compost made of 

 two-thirds of the best rotten sod loam 

 you have and one-third cow manure. 

 Now, plant the lilies, a good strong 

 crown in the middle of each tub, and 

 spread an inch deep of clean sand or fine 

 gravel over the soil to give all a nice, 

 glean appearance and to a certain extent 

 prevent the nniddiness of the water, and 

 set the tubs out in the sunshine wherever 

 .you wish tohavethem in summer, Bel'ore
