Description: Bowiea volubilisSN|11066]]SN|11066]] (climbing-onion, sea onion) is an interesting long living deciduous, perennial bulb. It is generally considered a succulent in the broad sense. The plants have many overlapping scales, which form tight, pale green, spherical bulbs that grows to 20 cm above the soil and to 25 cm in diameter (could take 70 years). The bulbs send up a twining fresh-green branched stem with few linear deciduous leaves. Dormant in winter, when the outer scales and many of the scale tips dry to a paper-like state, the plants burst to growth in late spring or summer, producing one or more very fast-growing stems that needs to be supported by a trellis or stake. The stems are covered with many leafless side-branches that may fall off. The small greenish-white flowers appear in spring. Two subspecies are recognized, the nominate form and Bowiea volubilisSN|11066]]SN|11066]] subsp. gariepensis (van Jaarsv.) Bruyns. A HTML color code is an identifier used to represent a color on the web and within other digital assets. Common color codes are in the forms of: Rose. Five parts of white lead mixed with two parts of carmine give a rose color that is suitable for inside work only. An admirable rose color may be obtained by using zinc white instead of white lead, as the zinc is a much purer white than the lead, and hence gives a purer tint. Vermilion. This bright red cannot be imitated by an admixture of ordinary pigments, but there are many excellent substitutes on the market, most of them being vermilionettes. Waterings: The plants are regularly watered and allowed to dry before watering again, pay attention don't overwater as stems may rot at the soil line. Some suggest to water just enough to keep the leaves from shrivelling this keep the plants more compact and enhances the leaves scent. If too much water is used, the leaves will turn yellow and get mushy. During the winter months, keep them quite dry or only water enough to keep the leaves from shrivelling.

Leaves: Sessile, dagger-shaped to strap-shaped, acuminate, scarcely narrowed above the sheath, somewhat fleshy, spirally arranged in stiff, upright rosettes, usually dark to metallic green above, with glossy purple or vivid violet underneath, 20-35 cm long by 3.5-5.5(-7.5) cm wide, hairless. Blooming season: Flowers appears in mid to late summer or autumn. They are short-day plant (flowers only when day length is less than 12 hours.) Myrtle. Three parts of dark chrome green, one part of ultramarine blue, and a little white lead will give an excellent myrtle color. There are, of course, other blues, but the above will be sufficient for all purposes, and the painter is urged not to adopt others until he knows their qualities from actual trial, and from having watched the effect which time and exposure to atmospheric action have had upon them.Yellow Lake. This is a somewhat fugitive color which has but little body, but is useful for glazing. To imitate it use equal parts of burnt umber and white lead and tint with chrome yellow and lake. Or, mix umber and white in equal proportions and add Naples yellow and scarlet lake. To obtain this color in its full richness it is quite necessary to glaze either admixture with yellow lake. Bronze Yellow. Mix together five parts of medium chrome yellow, three parts of white lead, and one part of raw umber. A mixture preferred by some painters is obtained from chrome yellow, French ochre and a little burnt umber. Foliage Brown. Mix burnt umber with raw and burnt sienna and lighten with white as may be necessary. His most recent publications are TROPICA, Color-ama of Exotic Plants with 7000 photos incl. Plants indoors. Also Hortica (8100 photos), Color Cyclopedia of Garden Flora in all Climates showing Hardiness Zones.

On the other hand, it is doubtful whether the mixture of lead and zinc is a good policy to follow. Many painters get excellent results by using white lead for the under coats and zinc white for the final coats. Portland Stone. Mix equal parts of yellow ochre and raw umber and lighten up with white until the desired tint is obtained.

Starling's Egg Green. A mixture of light chrome and Prussian blue, lightened up with white, will produce this color. Opera Pink. Tint white lead with a mixture of five parts of vermilion and one part of medium chrome green. Persian Green. This is only another name for emerald green, the vivid and somewhat staring hue being sometimes employed in oriental decorations and being then termed Persian green.

Nile Green. Five parts of white, nine of emerald green and six of Prussian blue will give this shade.

Color Tools

Brown Pink is a vegetable color often of a greenish hue. It works well in water and oil, but dries badly, and will not keep its color when mixed with white lead. Spanish brown and brown ochre are clays colored naturally by various oxides. Watering: During the summer growing period the plant appears to need much more water than the average succulent. Water when plant is dry and do not water again until the soil is completely dry again. Dislikes over-watering. Pay particular attention to make sure that they do not rot at the root from soggy soil. In a very humid situation in winter, it can rot even if totally dry. It likes dry air as much as dry soil.
