THE ENGLISH FLOWER GARDEN. 



DELPHINIUM. 



great variety in height, from I to 10 ft. ; 

 for their greater variety in shades of 

 colour, which range from almost scarlet 

 to pure white, from the palest and most 

 chaste lavender up through every con- 

 ceivable shade of blue to deep indigo ; 

 and for the variety of size and form of 

 their individual blooms, some of which 

 are single, some semi-double, and some 



Delphinium. 



perfectly double, and all set on spikes 

 ranging from i to 6 ft. in length. About 

 a dozen species have given rise to the 

 cultivated varieties, the chief species 

 being D. grandiflorum, formosum, lasio- 

 stachyum, cheilanthum, elatum, and pere- 

 grinum. 



CULTURE AND POSITION. The com- 

 binations in which they can be placed are 

 numerous. They are splendid objects in 

 various positions, and may be used in 

 various ways in the mixed border, in 



masses or groups in one or several colours, 

 or associated with other flowering plants 

 or with shrubs. Perennial Larkspurs 

 thrive in almost any situation or soil ; 

 they are easily increased, and are quite 

 hardy. A deep friable loam, enriched 

 with rotten manure, is a good soil for 

 them, but they will grow well in a hot 

 sandy soil if it be heavily manured and 

 watered. Every three or four years they 

 should be replanted and divided, and this 

 is best done in spring, just as they are 

 starting into growth, or in summer ; if it 

 is done in summer, cut down the plants 

 intended for division, and let them remain 

 for a week or ten days until they start 

 afresh ; then carefully divide and replant 

 them, shading and watering until they 

 are established. Late autumn division is 

 not advisable. Delphiniums can be made 

 to bloom for several months by continually 

 cutting off the spikes immediately after 

 they have done flowering. If the central 

 spike be removed, the side shoots will 

 flower, and by thus cutting off the old 

 flowers before they form seeds we cause 

 fresh shoots to issue from the base, and to 

 keep up a succession of bloom. Another 

 plan is to let the shoots remain intact 

 until all have nearly done flowering, and 

 then to cut the entire plant to the ground, 

 when in about three weeks there will be a 

 fresh bloom. In this case, however, to 

 keep the plants from becoming exhausted, 

 they must have a heavy dressing of 

 manure or manure-water. Top-dressings 

 keep the soil cool and moist, give the plants 

 a healthier growth, increase the number 

 and improve the quality of the flowers.
