Euphorbia mammillaris variegata 6.5cm
Origin and Habitat: Garden origin (Nursery produced cultivar)
Forma variegata: The attractive variegated form is easily recognized for its stem which is subtle-cream to frosty greenish-white colored and splashed with emerald green. In cold temperatures, stems become blushed with delicate rose. Flowers are red and orange.
Cultivation and Propagation: Euphorbia mammillaris f. variegata is an easy to grow ornamental species suited for any well drained soil in half or full sun.
Growth rate: It is a relatively fast growing species, but it it possible to increase the speed of growth to some extent by providing adequate amount of water, warmth, and fertilizer during the active growing season, but it’s susceptible to rotting if too wet and do not like a lot of water when it is on rest.
Soil and pots: It likes pots with generous drain holes, needs a very airy potting medium which mainly consists of non-organic material such us clay, pumice, lava grit, and only a little peat or leaf-mould,
Fertilization: Need a perfect fertilizer diet in summer. Use preferably a cactus and succulents fertilizer with high potassium content including all micro nutrients and trace elements or slow release fertilizer.
Exposure: This plant has an good heat tolerance, and need light shade exposures, it grows well even in full sun, but tolerate moderate shade, and a plant that has been growing in shade should be slowly hardened off before placing it in full sun as the plant will be severely scorched if moved too suddenly from shade into sun. The colour of this plant is much more marked if grown in full sun.
Watering: Euphorbia mammillaris f. variegata is an opportunistic grower, water regularly when it is growing. No water should ever be allowed to stand around the roots. Keep almost completely dry in winter. However, this spurge will tolerate dryness and can even thrives in poor, dry soils, but do better when grown in nutrient-rich soils with regular watering.
Hardiness: Tender. This spurge cannot tolerate any frost and can be difficult to get it to look its best without a good amount of heat and sun and so it is only really suited to the tropics. It can be grown outdoors in frost-free climates.
Variegation: A variegated plant has sectors, patches or stripes with two or more different colours, even distinct shades of green. Plants with variegated stems or leaves are often attractive and highly prized. In most species the stems or leaves are normally green, and variegated epidermis is an uncommon mutation, termed a chimera. A chimeral variegation is due to losing the ability to produce chlorophyll in some of the plant’s tissue, so that this tissue is no longer green. Tissues lacking chlorophyll are usually white or pale yellow coloured (due to carotenoid pigments) or red (due to betalain or anthocyanin pigments) contrasting with the normal green tissue. There are several forms of variegation, depending on the tissues that have been affected. The variegation in some forms is unstable. The extent and nature of the variegation can vary, and sometimes the plant will return to the green form. In others it is stable and does not change under normal conditions. Because the variegation is due to the presence of two kinds of plant tissue, propagating the plant must be by a vegetative method of propagation that preserves both types of tissue in relation to each other.
