Description
'White Supreme' is a vigorous, abundantly flowering and fragrant sweet pea variety, with large, ruffled pure white flowers. This sweet pea is one of the best white varieties. The very large, exquisitely ruffled blooms appear on long, voluble stems that grow to 1.80 m in height for 30 cm in width. The plants cover up their support in no time and are beautiful when used as a ground cover. In hanging baskets, they will romantically cascade down in lovely white garlands. Flowering takes places from June to August. Grow in a sunny location in fertile, moist soil.
Lathyrus odoratus is an annual herbaceous plant of the Fabaceae family originating from south-eastern Italy and Sicily. It can reach 1.80 m to 2.50 m in height and 30 cm in width in the space of a few months. Its quadrangular winged stems have stipules at their base, bear pairs of light-green leaflets and end in a terminal tendril. Flowering takes place from May to October depending on the variety. The papilionaceous flowers are grouped in axillary clusters. The flowers are composed of 5 petals: a standard, 2 free wing petals, and 2 fused petals. They give off a delightful fragrance, which has a sweet floral aroma with honeyed and musky notes. The fruit is a flat pod that splits at maturity, forcibly expelling its seeds away from the plant. It is essential to regularly remove wilted flowers, as seed production stunts flowering. Sweet peas root deeply in the ground to find water and nutrients.
Sweet peas are irreplaceable, their charming and old-fashioned flowers make quaint bouquets, look stunning in hanging baskets will soon cover up an old garden wall or fence. They are beautiful in summer flower beds, where they will use neighbouring plants or shrubs as a support. They can also form colourful carpets when grown as ground cover. Sweet peas are a must-have in cottage gardens alongside peonies, hollyhocks, fox gloves, peach leaved bellflowers, and columbines. They also do well in the fertile and well-watered soil of the vegetable garden, where they can be used as cut flowers.

Planting and care
Before sowing them, let the seeds soak in a bowl of water for 6 hours. This will improve the germination speed.
Sow Sweet Peas directly in place at the base of a trellis in March-April, in groups of 2 or 3 seeds, at a depth of 2.5 cm. Leave a minimum distance of 30 cm between two groups.
When the seedlings have reached the stage of the second pair of leaves, cut the tip of each stem to promote branching.
Regular watering without excess will accelerate its growth. A sunny location, fertilization for flowering plants, and the removal of faded flowers will promote abundant flowering from June to August.
Beware of snails and slugs that love to devour young plants.

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).
