216 OARDEX MANAGEMENT. 



Achillea, Orobus, Yucca, Scabiosa, CEnothera, Diantbus, Dyletra, Veronicas^ 

 Myosotis, Sacbys, &c. &c., arranged according to tbeir height, colour, and. 

 time of flowering, and intermixed with bulbous-rooted plants, such as the 

 Crocus, Narcissus, Hyacinths, Cyclamen, Oxalis, Tulips, Ornithogalum, 

 Scilla, Fritillaria, Lilium, Cypripedium, Gladiolus, Allium, Anemone, Ranun- 

 culus, Galanthus, Tritonia, Orchis, Colchicum, Pancratum, and Tigridia, 

 would make a very fine display. 



564. Most herbaceous plants are easily increased, either by dividing the 

 roots, by offsets, by cuttings from the side-shoots or roots, and by seeds. 

 Many of them, from their rapid growth, require taking up and dividing every 

 second year. To insure good flowers, a few strong stems of such plants as 

 Phloxes, Asters, &c., must be secured, in preference to a multiplicity of 

 smaller ones. Consequently, they require frequent and severe subdividing ;. 

 from this to the month of April being the best period for performing this 

 operation. Others, again, such as Gentians, Iberis, Alyssums, Achilleas, and 

 other similar flowering plants, thrive best without being often disturbed, and 

 must be increased by small-rooted offsets. These should be planted in the- 

 resen^e garden for the ensuing summer, and transferred to their flowering 

 quarters this time next year. Double rockets, scarlet lychnis, hollyhocks, 

 and other double-flowering plants, are often increased by cuttings. These can: 

 generally be obtained either by thinning the young shoots in the spring, or by 

 securing all that appear at the bottom of the flowering-stems in the autumn. 

 At either period they should be inserted in sandy soil, covered with a handor 

 bell-glass, and receive a gentle warmth until rooted. If inserted in the spring, 

 they will of course be transferred to the reserve garden as soon as the rooting- 

 and gradual hardening processes are completed. If this is done in the autumn, 

 they will be safer under shelter until the end of April. In either case, with, 

 liberal treatment, they may flower the next summer. To induce autumn-struck 

 cuttings to do this, however, they must be potted off" in rich soil as soon as- 

 rooted, into separate pots, and receive the stimulus of a genial atmosphere^ 

 and shelter from the weather. All the mints, galiums, and other plants with 

 running or creeping roots, are so easily and obviously increased as to require 

 no instructions. 



565. All single-flowering herbaceous plants may also be increased readily by 

 seed. They may either be sown as soon as rijie, or after September in pots ;. 

 if before that period, in the reserve garden. If sown this or next month, on 

 beds of light soil, and the plants carefully transplanted two or thi-ee times 

 during the summer, they may be transfei'red to their blooming quarters next 

 November ; if they have been properly treated, they will flower profusely the 

 following season. 



566. The grand feature in the culture of bulbous-rooted plants is, that most 

 of them, from peculiarity of constitution, or from their mode of increase, re- 

 quire to be taken up and replanted every year, or every second or third year 

 at the farthest. Where this is not done, the flourishing bulbs are smothered 

 with the quantity of small offsets that form around them. These offsets not-
