Many of the species are grown in cultivation, and innumerable hybrids and cultivars. Cuttings from flowering begonias root freely in sandy soil, if placed in heat at any season when moderately firm; as soon as rooted, they should be potted singly into 75 mm pots, in sandy loam mixed with leaf mould and sand. They should be stopped to keep them bushy, placed in a light situation, and thinly shaded in the middle of very bright days. In a few weeks they will require another shift. They should not be overpotted, but instead assisted by manure wa ...

Some variegation is attractive and ornamental, and gardeners tend to preserve these. The term is also sometimes used to refer to colour zonation in flowers. Variegation - Chimeral variegation. Plants bearing such variegation are chimeras, with more than one type of genetic makeup in their tissues. A lack of chlorophyll producing tissue in some tissues c ...

Plants bearing such variegation are chimeras, with more than one type of genetic makeup in their tissues. A lack of chlorophyll producing tissue in some tissues causes variegation with white or yellow coloured zones on the leaf, contrasting with the usual green tissue. It is due to some of the plant’s meristematic tissue losing the ability to produce chloroplasts, so that the tissue it produces is no longer green. In a common type of such variegation, the part of the meristem that produces epidermal tissue loses the ability to produ ...

The Arboretum was established in 1918 by the Hawaiian Sugar Planters Association to demonstrate watershed restoration and test various tree species for reforestation, as well as collect living plants of economic value. In 1953, it became part of the University of Hawaiʻi. Its over 15,000 accessions focus primarily on the monocot families of gingers, heliconias, bromeliads, and aroids. Today, the Arboretum continues to develop its extensive tropical plant collection, while emphasizing native Hawaiian plant ...

Some variegation is due to visual effects due to reflection of light from the leaf surface. This can happen when an air layer is located just under the epidermis resulting in a white or silvery reflection. It is sometimes called blister variegation. Pilea (aluminum plant) is an example of a house plant that shows this effect. Cyclamen hederifolium leaves show such patterned variegation, varying between plants, but consistent within each plant. Another type of reflective variegation is caused by hairs on parts of the leaf, which may be coloured differently from the leaf ...
