Jonah is the Kitab al Tank (" Book of Exact Investigation"), which consists of two parts, regarded as two distinct books - the Kitab alLuma ("Book of Many-coloured Flower-beds") and the Kitab alusul ("Book of Roots").
aurem is the "golden-feather" of gardens, so much employed as an edging to flower-beds.
In the case of villa gardens there is usually little choice: the land to be occupied is cut up into plots, usually rectangular, and of greater or less breadth, and in laying out these plots there is generally a smaller space left in the front of the villa residence and a larger one behind, the front plot being usually devoted to approaches, shrubbery and plantations, flower beds being added if space permits, while the back or more private plot has a piece of lawn grass with flower beds next the house, and a space for vegetables and fruit trees at the far end, this latter being shut off from the lawn by an intervening screen of evergreens or other plants.
In one the ground is turf, out of which flower-beds, of varied patterns, are cut; in the other the flower-beds are separated by gravel walks, without the introduction of grass.
P. vulgaris, 6 in., affords numerous handsome singleand double-flowered varieties, with various-coloured flowers for the spring flower-beds and borders.
