Here Ambrosia was plentiful, but is plentiful no longer; and Walpole garden lovers seek seeds of it from the Worcester garden. I think it dies out generally when all the weeding and garden care is done by gardeners; they assume that the little plants of such modest bearing are weeds, and pull them up, with many other precious seedlings of the old garden, in their desire to have ample expanse of naked dirt. One of the charms which was permitted to the old garden was its fulness. Nature there certainly abhorred a vacant space. The garden soil was full of resources; it had a seed for every square inch; it seemed to have a reserve store ready to crowd into any space offered by the removal or dying down of a plant at any time.
Let me tell of a curious thing I found in an old book, anent our subject—green flowers. It shows that we must not accuse our modern sensation lovers, either in botany or any other science, of being the only ones to add artifice to nature. The green Carnation has been chosen to typify the decadence and monstrosity of the end of the nineteenth century; but nearly two hundred years ago a London fruit and flower grower, named Richard Bradley, wrote a treatise upon field husbandry and garden culture, and in it he tells of a green Carnation which "a certayn fryar" produced by grafting a Carnation upon a Fennel stalk. The flowers were green for several years, then nature overcame decadent art.
There be those who are so enamoured of the color green and of foliage, that they care little for flowers of varied tint; even in a garden, like the old poet Marvell, they deem,—
"No white nor red was ever seen
So amorous as this lovely green."
Such folk could scarce find content in an American garden; for our American gardeners must confess, with Shakespeare's clown: "I am no great Nebuchadnezzar, sir, I have not much skill in grass." Our lawns are not old enough.
A charming greenery of old English gardens was the bowling-green. We once had them in our colonies, as the name of a street in our greatest city now proves; and I deem them a garden fashion well-to-be-revived.
The laws of color preference differ with the size of expanses. Our broad fields often have pleasing expanses of leafage other than green, and flowers that are as all-pervading as foliage. Many flowers of the field have their day, when each seems to be queen, a short day, but its rights none dispute. Snow of Daisies, yellow of Dandelions, gold of Buttercups, purple pinkness of Clover, Innocence, Blue-eyed Grass, Milkweed, none reign more absolutely in every inch of the fields than that poverty stricken creature, the Sorrel. William Morris warns us that "flowers in masses are mighty strong color," and must be used with much caution in a garden. But there need be no fear of massed color in a field, as being ever gaudy or cloying. An approach to the beauty and satisfaction of nature's plentiful field may be artificially obtained as an adjunct to the garden in a flower-close sown or set with a solid expanse of bloom of some native or widely adopted plant. I have seen a flower-close of Daisies, another of Buttercups, one of Larkspur, one of Coreopsis. A new field tint, and a splendid one, has been given to us within a few years, by the introduction of the vivid red of Italian clover. It is eagerly welcomed to our fields, so scant of scarlet. This clover was brought to America in the years 1824 et seq., and is described in contemporary publications in alluring sentences. I have noted the introduction of several vegetables, grains, fruits, berries, shrubs, and flowers in those years, and attribute this to the influence of the visit of Lafayette in 1824. Adored by all, his lightest word was heeded; and he was a devoted agriculturist and horticulturist, ever exchanging ideas, seeds, and plants with his American fellow-patriots and fellow-farmers. I doubt if Italian clover then became widely known; but our modern farmers now think well of it, and the flower lover revels in it.
The exigencies of rhyme and rhythm force us to endure some very curious notions of color in the poets. I think no saying of poet ever gave greater check to her lovers than these lines of Emily Dickinson:—
"Nature rarer uses yellow
Than another hue;
Saves she all of that for sunsets,
Prodigal of blue.
Spending scarlet like a woman,
Yellow she affords
Only scantly and selectly,
Like a lover's words."
