Description
Veronica longifolia Lila Karine, also known as Long-leaved Lila Karine Speedwell, is an elegant and spectacular perennial. It forms clumps with upright stems, flooding the borders with long, flexible spikes adorned with small silver-blue mauve flowers that perfectly complement its ashy green foliage. This plant thrives in moist and well-drained soil and is ideal for sunny mixed borders.
Veronica longifolia is a herbaceous plant from the plantain family (Plantaginaceae), found in northern and central Europe and Asia. It can grow quite tall, forming clumps with erect stems that can reach over 1m (3ft) in the wild. Lila Karine reaches a height of 40-60cm (16-24in) and a width of 40cm (16in). Its leaves are often arranged in whorls of three or four, although they can also be opposite. They are narrow and lanceolate, with a short petiole, deeply toothed and silver-green. The flowering period is June-July with dense clusters of flowers in long, slender, flexible spikes. The tiny pale blue-silver to mauve flat flowers have four petals and two protruding stamens. The nectar-rich flowers are followed by heart-shaped capsule fruits.
This very hardy speedwell is easy to grow and complements a variety of plants to create stunning summer compositions, especially along the banks of a pond. Plant it alongside Joe-Pye weed, sneezeweed, Lythrum salicaria, Filipendula rubra 'Venusta', and marsh spurge. In a wilder setting or as a backdrop in a border, this elegant perennial looks fantastic with tall grasses like Miscanthus, Panicum, and Stipa...

Planting and care
Veronica longifolia is an easy-to-grow perennial, it prefers a rich and light soil with a slightly alkaline (calcium-rich) tendency. It likes humid atmospheres and a spot close to water but needs light soil. It grows and flowers best in the sun. Veronica longifolia can be planted at almost any time of the year, except during periods of frost and summer drought. Cut the faded stems to promote new flowering. Added compost at the base of the plant every spring will give it vigour. Avoid using nitrogen-rich fertilisers, as they will weaken the vegetation and make the stems bend more easily. In spring, cut back to the base. Fresh foliage will emerge in spring.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).
The flowering period indicated on our website applies to countries and regions located in USDA zone 8 (France, the United Kingdom, Ireland, the Netherlands, etc.)
It will vary according to where you live:- In zones 9 to 10 (Italy, Spain, Greece, etc.), flowering will occur about 2 to 4 weeks earlier.
- In zones 6 to 7 (Germany, Poland, Slovenia, and lower mountainous regions), flowering will be delayed by 2 to 3 weeks.
- In zone 5 (Central Europe, Scandinavia), blooming will be delayed by 3 to 5 weeks.
In temperate climates, pruning of spring-flowering shrubs (forsythia, spireas, etc.) should be done just after flowering.
Pruning of summer-flowering shrubs (Indian Lilac, Perovskia, etc.) can be done in winter or spring.
In cold regions as well as with frost-sensitive plants, avoid pruning too early when severe frosts may still occur.
The planting period indicated on our website applies to countries and regions located in USDA zone 8 (France, United Kingdom, Ireland, Netherlands).
It will vary according to where you live:
- In Mediterranean zones (Marseille, Madrid, Milan, etc.), autumn and winter are the best planting periods.
- In continental zones (Strasbourg, Munich, Vienna, etc.), delay planting by 2 to 3 weeks in spring and bring it forward by 2 to 4 weeks in autumn.
- In mountainous regions (the Alps, Pyrenees, Carpathians, etc.), it is best to plant in late spring (May-June) or late summer (August-September).
The harvesting period indicated on our website applies to countries and regions in USDA zone 8 (France, England, Ireland, the Netherlands).
In colder areas (Scandinavia, Poland, Austria...) fruit and vegetable harvests are likely to be delayed by 3-4 weeks.
In warmer areas (Italy, Spain, Greece, etc.), harvesting will probably take place earlier, depending on weather conditions.
The sowing periods indicated on our website apply to countries and regions within USDA Zone 8 (France, UK, Ireland, Netherlands).
In colder areas (Scandinavia, Poland, Austria...), delay any outdoor sowing by 3-4 weeks, or sow under glass.
In warmer climes (Italy, Spain, Greece, etc.), bring outdoor sowing forward by a few weeks.
