Garden spurge - Euphorbia


the genus euphorbia has about 7500 species of plants, of which only 800-900 are succulent plants, the rest are shrubs, perennials or medium-sized trees. Among the many species there are a few dozen that are perennial plants, or evergreen garden shrubs. Generally they have a quite vigorous development; they constitute large clumps, with erect stems, poorly branched, with lanceolate or oval foliage. The foliage colors are various, from the dark green of the E 'amygdaloides, to the light green, streaked with white E. marginata. During spring, summer and autumn produce characteristic inflorescences, consisting of small greenish flowers, subtended by round bracts, red or orange, but sometimes white or yellow. The species are many, some are evergreen, like E. characias, others lose their foliage in winter, or during the hot summer days. These are generally easy-to-grow plants, which grow from 30-40 cm perennials, up to 120-150 cm, which are more vigorous.


Regarding exposure, most euphorbia species prefer bright, sunny locations for a few hours a day, but sheltered from direct light during the hottest hours of the day. Some species particularly like shade, such as Euphorbia amygdaloides. Most species do not fear the cold, there are also innumerable hybrids, very resistant to frost, which generally do not lose their foliage. Given the vastness of types that are included in the garden euphorbia genus, it is certainly possible to find the one that best suits the climatic conditions.


Garden spurge plants prefer medium watering, from March to October, with little or no watering during the winter period. There are numerous exceptions, it is good to inquire for each case at the time of purchase. In general they are watered during the vegetative period, allowing the soil to dry well between one watering and another, in fact, it is good to check that water stagnations do not form which could compromise the health of the plant.


The advice regarding the type of soil to be used for the best growth of the plant is to cultivate garden euphorbia plants in soil rich in organic, soft and loose matter, very well drained. Specimens grown in containers should be repotted every 2-3 years to allow them to develop at their best.
Check that the type of soil you are using is light and allows perfect drainage, so as to guarantee the best possible development of the plant.


The multiplication of euphorbia plants usually occurs by division of the tufts in spring. Evergreen species can be multiplied by cuttings at the end of summer.
Obviously it is necessary to understand which variety the multiplication process is performing to understand which is the best methodology.
