'ongiflorum, if it shows its buds at 

 I'.'aster, can easily be held for Memorial 

 lay. In the case of L. candidum, if 

 imds can be seen May 1, they will be 

 in time, provided they have a light, 

 sunny house. 



Standard Heliotropes. 



Heliotropes as bedding plants are 

 well known and popular. A bed of 

 them is much improved if one or two 

 standai;ds can be dotted through it. The 

 growing of standards presents few diffi- 

 culties. They can be had either from 

 cuttings or seed. The latter produces 

 the more vigorous plants. Select the 

 most robust plants for standards. Rub 

 away all side shoots and remove all 

 flowers. Carry up the stem to any de- 

 sired height before finally pinching it 

 and allowing it to make a head. Of 

 course, a stake of sUjfficient stoutness 

 to hold the plant erect must be used. 

 It is not now too late to root cuttings 

 to grow on into standards. If grown 

 along all summer and winter, these can 

 be flowered if desired for Easter, as 

 more than one enterprising grower has 

 done, or if preferred can be potted on 

 and sold in large pots or small tubs for 

 summer flowering. If kept well watered 

 and fed, these heliotropes will bloom 

 practically all summer, and if big speci- 

 mens are desired, the old plants can be 

 carried over winter moderately cool 

 and dry and then pruned back a little 

 and started in heat as spring advances. 

 These standards, when securely staked 

 and plunged to prevent blowing over, 

 are charming features in any garden. 

 Marguerites. 



Marguerite plants which are grown 

 for cutting should now have the pots 

 or boxes stood on the bods or benches, 

 so that they can root through freely, 

 and will, in addition, need lots of water 

 and frequent feeding, or the stems will 

 not have the length or the flowers the 

 size we would like to see. Plants set 

 out in narrow benches will now be 

 coming to flower freely and should give 

 a crop until the latter part of June. 

 Marguerites as winter bloomers must 

 have their root run restricted, but after 

 the early spring they flower finely 

 planted directly in the benches. Young 

 stock, both yellow and white varieties, 

 should have the flowers pinched off. 

 These should be carried over summer 

 in a cold house or frame, and if they 

 can have shade from laths to keep them 

 cooler, they will summer much better, 

 especially the yellow varieties. Mar- 

 guerites are being more grown every 

 vear and sell as well as any flower on 

 the market, and the grower who may 

 have a house not quite adapted for car- 



nation or rose culture may turn it to 

 good advantage by filling it with mar- 

 guerites. Myosotis can be planted 

 along the edges of the benches and, if 

 there are any posts, run a few sweet 

 peas up them. 



NATIONAL SWEET PEA SOCIETY. 



The National Sweet Pea Society of 

 America will hold its annual convention 

 and summer exhibition at Philadelphia, 

 June 23 and 24, 1911, under the auspices 

 of the Pennsylvania Horticultural So- 

 ciety and in connection with its annual 

 sweet pea exhibition. 



A guarantee fund for a general list 

 of prizes has been headed by our presi- 

 dent, W. Atlee Burpee, the Henry F. 



Michell Co., Henry A. Dreer, Inc., Ar- 

 thur T. Boddington and other seed 

 houses contributing. A preliminary 

 schedule will be published in a few 

 days, showing list of prizes, cups, etc., 

 and a general program for the conven- 

 tion. Contributions for additional prizes 

 in the form of cash or cups, etc., -are in- 

 vited from the trade. 



The prize list will amount to about 

 $500, which should act as a great stim- 

 ulus to the lovers of sweet peas, and 

 intending exhibitors should make due 

 preparations for this, the third annual 

 exhibition given by our society. For 

 further particulars write to the under- 

 signed at 342 West Fourteenth street, 

 New York city.

THE CUT FLOWER CROP. 



Growth is now rapid under glass, and, 

 unless the plants are looked over fre- 

 quently, there is a danger of the haulm 

 becoming bent, which will spoil the 

 flowering stems for sale purposes. With 

 increasing sun heat, the beds dry out 

 more quickly and water supplies must 

 be increased. March and April are the 

 two months when sweet peas under 

 glass reach their greatest perfection. 

 When the early summer torrid waves 

 arrive, they rapidly deteriorate in qual- 

 ity. They are naturally cool, moisture- 

 loving subjects and no attempt should 

 ever be made to force or coddle them. 

 Plaiits flowering should be supplied with 

 liquid manure once a week, or in place 

 of this have a top-dressing of cow or 

 sheep manure hoed in before watering. 

 Keep the ventilators open whenever the 

 weather will permit, and there are few 

 days after April comes in when they 

 cannot be opened for at least a few 

 hours daily. A night temperature of 50 

 degrees will be about right. This can 

 be advanced 2 or 3 degrees as the 

 month progresses. The Spencer varie- 

 ties are now starting to flower and 

 from this time on will command the 

 best prices. Out of the numerous va- 



rieties now listed, the original Countess 

 Spencer remains at the head of the pro- 

 cession as a seller. 



As the outdoor sweet peas come 

 through the ground, run the cultivator 

 freely among them, and where they 

 have come up too thickly this is an 

 opportune time to do necessary thin- 

 ning. If strong haulm, which will carry 

 stout flower stems, is wanted, the 

 plants must be given ample room in 

 which to develop. A row of plants 

 thickly sown may look pleasing in the 

 early stages of growth, but as the sea- 

 son advance^i these thick seedlings sim- 

 ply smother one another, stem-rot de- 

 velops and the flower stalks, instead of 

 carrying three and four flowers each, 

 average half that number. Get sup- 

 ports into position as soon as possible. 



Plants started in pots in a cold green- 

 house or coldframes can go outdoors any 

 time after the middle of April. Harden 

 them off gradually first. Before setting 

 them out place the supports in the 

 rows and do not crowd the plants. A 

 foot apart will prove more satisfactory 

 than half that distance; that is, if the 

 little pots contain an average of three 

 plants each.
