In this second post about the Euphorbia genus we will talk about the three remaining species we have in our nursery
Euphorbia griffithii 'Fireglow'
It is a compact shrubby plant. Its maximum dimensions can reach one meter high by one meter wide.
Its leaves are evergreen, lanceolate and entire. These are reddish green in color, with the stem being very showy dark red.
Flowering occurs during the months of April to July approximately. The flower is orange-red in color. It is a small unisexual flower, as in all euphorbias, which groups into flower clusters known as cyathium.

It is a species belonging to hardiness zone number 8, with an annual minimum average temperature range of -12.2 / -6.7°C.
Its water needs, as with the rest of plants of this genus, are very low and no watering is necessary once the plant is well rooted in the place where we have planted it. This place can be in full sun, although it also tolerates partial shade.
It can live in all types of soils, preferably well drained. And with a very wide pH range, in acidic, neutral or alkaline soils.
Euphorbia myrsinites
It is a creeping and perennial shrubby plant. It is the shortest euphorbia we have at Sala Graupera, as its dimensions can reach a maximum of 20 centimeters high by 40 wide.
The leaves are oval, pointed at the end and arranged spirally along the stem, about two centimeters long. These are very ornamental glaucous green in color.
Flowering occurs during the months of April to June approximately. It is a very ornamental inflorescence, due to the bracts, which during spring take on a very showy greenish-yellow tonality.

It is a species belonging to hardiness zone number 7, with an annual minimum average temperature range of -17.7 / -12.3°C.
Its water needs are very low and no watering is necessary once the plant is well rooted.
It is a euphorbia that prefers to be planted in full sun to be able to show all its potential.
It can live in all types of soils, even nutrient-poor soils, preferably well drained. And with a very wide pH range, in acidic, neutral or alkaline soils.
It is important to keep it controlled in the place where we have planted it, performing a pruning of the flower just after flowering, to avoid its propagation through seeds.
Euphorbia rigida
It is a compact shrubby plant. Its maximum dimensions can reach 60 centimeters high by 80 wide.
This euphorbia stands out for the glaucous color of its leaves and stems, these leaves are narrowly elliptical and pointed at the apex.
Flowering occurs during the months of March to May approximately, at the end of winter. The flower bracts are yellow in color, this color contrasts very well with the glaucous color of the plant, giving color to the garden when the spring flowering of many other species has not yet begun.

It is a species belonging to hardiness zone number 8, with an annual minimum average temperature range of -12.2 / -6.7°C.
Its water needs are also very low, it is very drought resistant, but if we want to enhance it in our garden we will do some watering during summer; it preferably requires being planted in full sun.
It can live in all types of soils, even in nutrient-poor and shallow soils, as long as they are well drained. And with a very wide pH range.
All these species are suitable for planting to make borders, in rock gardens or among aggregates (always in well-draining substrates). They are also ideal for mixing with different sustainable gardening plant species, creating multi-specific flowerbeds.
