Description
Ipomoea purpurea 'Kniola’s Black Night' is a truly fascinating variety that features very dark purple blooms with a cerise pink star and small white throat. In one season, it sends out long, twining stems loaded with buds that burst into bloom against mid-green foliage. This gorgeous Morning Glory is ideal for ground covers or airy displays when grown up a support. It thrives in a warm, sunny, sheltered position in loose, cool soil.
Ipomoea purpurea, poetically named Morning Glory, is a very vigorous perennial climber that belongs to the Convolvulaceae family. It is native to tropical America, probably Mexico. This tuberous rooted plant is not cold-hardy and is often treated as an annual in colder climates. 'Kniola’s Black Night' produces 1.80 m long, twining stems that are quick to scramble up nearby supports. From July until the first frosts, it produces an abundance of funnel-shaped corollas, each measuring about 4 cm in diameter. Silky-smooth to the touch, they display intense dark purple blooms that almost seem black when set against the light. They are marked with a cerise red and black star and small white throat. Although the delicate blooms open and close in the space of day, they are constantly replaced on the plant. The stems bear 5 to 10 cm, oval to heart-shaped leaves, occasionally three-lobed. Their matt, mid green colour really sets off the brightly coloured blooms. Each plant produces about 100 seed pods, i. e. about 600 seeds at the end of the growing season, before the first frosts.
Ipomoea is a distant cousin of common bindweed. Although it is distinctly less cold-hardy, it is such an enthusiastic grower that it makes an excellent annual. It thrives in any well-drained garden soil in a warm, sheltered position. It combines well with other short-lived climbers such as sweet peas or nasturtiums. It eagerly scrambles over trellises, pergolas, arches, balcony railings, trees, shrubs and even other vines such as clematis and wisteria. If it can't find a support, it can be left to roam free on the ground. Morning Glory is ideal for hiding unsightly walls or dead trees.

Planting and care
From May to June, sow the Morning Glory in open ground or in a large pot. Soaking the seeds in a bowl of water for 24 hours before sowing helps to speed up the germination process.
Make small holes about 1 cm deep, spaced 50 cm to 1 m apart. Place 4 or 5 seeds in each hole, then cover them and water.
It takes about 18 days to see the first shoots emerge from the ground.
To save time on flowering, you can sow your seeds in March-April in buckets at a temperature of 18°C, then transplant your plants into the garden after the last frost.
In summer, make sure your Morning Glory plants do not lack water as it would harm their beautiful flowering. Water preferably early in the morning or in the evening. Avoid placing them in scorching hot locations, as the foliage wilts very quickly and the heat dehydrates the plants. You can remove faded flowers so that the plant does not exhaust itself by producing seeds. Morning Glories are so fertile that the first seeds that fall to the ground can germinate very quickly and form new young plants before winter.
The soil should not be excessively rich in nitrates, as this would promote foliage growth at the expense of flowering.

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.
