Hebe and Veroniche
To the Hebe genus belong some species of evergreen shrubs, of medium or small size, originating from Australia and New Zealand, but widespread for many years in European gardens; their resemblance to a native plant made them commonly called by the name of this plant, namely Veronica, as a perennial of European origin, of the same family.
These shrubs can be roughly divided into two large groups; one groups ebe with medium or large foliage, about 3-6 cm long, the other brings together all those with small leaves, about 1-3 cm long. In general all ebe have evergreen foliage, glossy and leathery, very dense and compact, oval or lanceolate; the leaves are very decorative, since they vary in color: variegated, spotted, very dark green, or even almost yellow.
In spring and autumn, at the apex of the stems, panicles of small white, purple or blue flowers develop, very decorative, which bloom over a few weeks.
Hebe - Hebe: Hebe diseases
Veronica is a very rustic and resistant species that has no diseases or insects that affect it in a particular and specific way. To avoid the onset of any kind of disease due to a weakening of the plant, the first rules to be respected are the choice of an adequate soil and an irrigation correlated to the temperature and the needs of this plant.
The soil or cultivation soil of Hebe must be tending to acid and the plant needs loose soils rich in organic substance. In addition to this, the plant must be planted in a well-drained soil that should not be watered in an exaggerated way or, in all ways, water stagnation should be avoided. The stagnation is in fact one of the first causes of a possible fungal attack or of a beginning of root rot or of the collar.
In addition to these more cultural aspects, more related to prevention and good cultivation practices, those who cultivate in the garden of Veronica plants will have to pay attention mainly to the aphids that can attack the leaves of this plant.
