The Lathyrus odoratus Spencer 'Mars' is a variety of Sweet Pea of large size from the Spencer series, a series known for its powerful fragrance, floriferousness, and vigour. 'Mars' offers large original bicolour flowers. On a white background, they are speckled and finely edged with scarlet red. Delightfully scented and carried by long sturdy stems, they are ideal for bouquets. It is an annual, climbing or creeping, plant that quickly colonises a large area. It is easily sown and grown in the sun, in fertile and moist soil.
The Lathyrus odoratus Spencer 'Mars' is an annual herbaceous plant of the Fabaceae family, whose ancestors originate from southeastern Italy and Sicily. Thanks to its tendrils, it can climb or crawl up to 2.50 to 3 m in height and 40 cm in width in a few months. It is adorned with large undulating flowers. The leaves are paired on quadrangular stems, with stipules at the base and extended into tendrils. Their colour is a light green, more or less greyish or bluish. Flowering occurs from June-July to August-September, depending on the sowing date. The papilionaceous flowers are large to very large, clustered in axillary clusters. They consist of 5 petals, more or less frizzled, with the uppermost, also the largest, forming a banner, while the others have an intermediate shape between lip and tube. They release a powerful, yet delicate, scent, with a sweet floral aroma with hints of honeyed and musky tones. The fruit is a flat pod that twists as it expels its seeds at a distance. It is essential to remove faded flowers, as seed production immediately stops flowering. Sweet peas root deeply in the soil to draw water and nutrients. They enjoy warmth, as well as rich, loose, and moist soils.
The Lathyrus odoratus Spencer 'Mars' is an attractive variety, with a gentle and unique character. As annual plants, sweet peas bravely cling their tendrils to numerous supports that they invade in a season, and their charming flowering is essential in the garden. Plant them at the foot of a wire fence or a garden shelter. On the ground, in a variety mix, they form beautiful colourful carpets. They are equally charming in summer beds, using neighbouring plants or bushes as support. By regularly removing the pods that form after the flowers, they generously bloom all summer. In a cottage garden or vegetable patch, where they appreciate fertile and well-watered soil, they accompany columbines, hollyhocks, or foxgloves. They make splendid bouquets. They are majestic in a large hanging basket, cascading into romantic garlands. Mix 'Mars' with white, red, and pink flowers for a splendid colour palette.

Botanical data
Before sowing them, let the seeds soak in a bowl of water for 6 hours. This will improve the germination speed.
Sow the Sweet Pea Spencer Mars 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 reach the stage of the second pair of leaves, cut the tip of each stem to encourage branching.
Regular watering, but not in excess, will accelerate its growth. A sunny location, a supply of fertiliser 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).
