All the poppies are worthy, from the lovely Shirley, with its butterfly-winged petals, to the Eschscholtzia, the state flower of California.
One thing to be remembered about poppies is not to rely greatly upon their durability and make the mistake of expecting them to fill too conspicuous a place, or keep long in the marching line of the garden pageant. They have a disappointing way, especially the great, long-stemmed double varieties, of suddenly turning to impossible party-coloured mush after a bit of damp weather that is most discouraging. Treated as mere garden episodes and massed here and there where a sudden disappearance will not leave a gap, they will yield a feast of unsurpassed colour.
To me the Shirley is the only really satisfactory annual poppy, and I sow it in autumn and cover it after the fashion of the cornflower, as it will survive anything but an open, rainy winter, and in the resulting display that lasts the whole month of June it rivals the roses in everything but perfume.
Godetia is a good flower for half-shady places that it is difficult to fill, and rings the colour change from white through pink to crimson and carmine. Marigolds hold their own for garden colour, but not for gathering or bringing near the nose, and zinnias meet them on the same plane.
The morning-glory tribe of ipomaea is both useful and decorative for rapid-growing screens, but heed should be taken that the common varieties be not allowed to scatter their seeds at random, or the next season, before you know it, every plant in the garden will be held tight in their insinuating grasp. Especially beautiful are the new Imperial Japanese morning glories that are exquisitely margined and fringed, and of the size and pattern of rare glass wine cups. Petunias, if judiciously used, and of good colour, belong in the second grade of the first rank. They have their uses, but the family has a morbid tendency to run to sad, half-mourning hues, and I have put a black mark against it as far as my own garden is concerned.
Drummond phlox deserves especial mention, for so wide a colour range has it, and so easy is its growth (if only you give it plenty of water and elbow room, and remember that a crowded Drummond phlox is an unhappy plant of short life), that a very tasteful group of beds could be made of this flower alone by a careful selection of colours, while by constant cutting for the house the length of the blooming season is prolonged.
