Rubellum was originally distributed as Chrysanthemum erubescens, under which name it received an award of merit from the R.H.S.
The culture of theseis very simple, for they are not particular as to soil, although they prefer one which is well drained but yet does not dry out during the summer. Of perennial habit, C. rubellum and its hybrids are absolutely hardy and will go on to give a bright for years. It is possible to secure varieties which will provide colour from early August until November, and many make a bright show at a time when most other perennials have finished blooming.
Fresh stock can be easily produced by taking sucker growths withattached and planting them in well-cultivated soil. In addition, secured from young growths in the spring, prepared in the usual way and placed in a cold frame or under cloches, will freely in a sandy soil. Once rooted, the lights are removed and the growing points of the young plants taken out to induce the production of lateral shoots. After this the plants will grow rapidly.
The planting season extends throughout April and early May, and the young plants should be placed in a sunny, being firmly embedded in the soil and watered in. They quickly establish themselves, and quite small plants will give a good display the same year. When growing for cut , all that is needed in future years is to remove weak and badly placed growths, so as to ensure good sprays of long . The plants should be spaced about a ft apart each way.
Good varieties of rubelluminclude ‘Lady Brocket’, apricot-pink; ‘Jessie Cooper’, chestnut-crimson; ‘Duchess of Edinburgh’, velvety-red; ‘Prince Charles’, old rose; ‘Wild Honey’, peach-yellow blended with coral, and ‘Red Ensign’, indian-red with bright yellow centres.
There are a number of hardy pompom varieties which are invaluable forpurposes. They make dainty sprays and provide a wonderful splash of colour. Among the best are ‘Andy Pandy’, attractive yellow; ‘Bob’, bright red; ‘Chick’, rose; ‘Huddle’, rosy-salmon; ‘Janet’, shell-pink; lante Wells’, golden-yellow; ‘Nipper’, salmon; ‘Paddy’, bronze-red; ‘Tommy Trout’, amber edged with bronze centre.
There are a few-centred varieties which grow well under normal garden cultivation and look well when cut. They are available in shades of red, bronze and yellow.
