Millennium – Modern Breeding, Classic Warmth

Red sweet peas are not red in the way a rose is red. They lean toward ruby, claret, or crimson, and the best of them have a complexity that pure red never manages. Millennium is a case in point. The standard petals are a rich ruby with a purple cast; the wings are more subdued, leaning violet-purple. The result is a flower that looks subtly bicoloured without being obviously so – the effect is closer to a stained-glass window than a paint swatch.

The flowers are large at about 6cm across, generous for a Spencer, and properly waved. Stems are long, straight, and strong, which is why Millennium has a following on the show bench. Exhibitors favour it as one of the best red-class sweet peas available, and the NSPS has recognised it at national level. For the rest of us, it is a vivid, well-built variety that adds real punch to a mixed display.

A Beacon of Colour

In a garden full of pastels, Millennium is the exclamation mark. The ruby-and-purple colouring is visible from across a border, and it catches the eye in a way that softer colours simply cannot. Grow it up a wigwam in the centre of a planting scheme and it acts as an anchor: everything else arranges itself around it.

The colour holds well through the life of each bloom, which matters for exhibition and for the vase. In full sun, the ruby tones glow. On overcast days, the purple deepens and the flower takes on a richer, moodier quality. Scent is lighter than you might expect from a variety with this much visual presence, rated 3 on the Parsons scale, but it is clean and pleasant, and it blends well with more powerfully scented varieties in a mixed bunch.

Pairing Ideas

For a warm-toned scheme with real range, pair Millennium with Bobby's Girl (shell-pink) and Cathy (clotted cream). The ruby, pink, and cream together have a painterly quality, rich without being heavy. For something more dramatic, Jilly (ivory-cream) alongside Millennium creates a stark and beautiful contrast.

Millennium's vivid colour looks magnificent threaded through a white-flowered climber. A jasmine, summer jasmine especially, makes a striking partner on a warm wall, and the combined scent of sweet pea and jasmine on a July evening is something you do not forget.

Why Buy Your Sweet Pea Seedlings from Ashridge?

We have been growing sweet peas in Somerset since the early 2000s. The seed - which we collect - is hand-sown at two seeds per plug and the weaker seedling is removed. Every plant is then pinched out to encourage bushy growth and hardened off before dispatch. What you are buying are sturdy, garden-ready jumbo plug plants that have had the best possible start.

We send your sweet peas out by next-day courier between March and May, packed in purpose-designed recycled cardboard packaging. The moment they arrive, they are ready to go into the ground or a container. If anything is not right, we have real people on the phone in Somerset who will sort it out. We hold a Feefo Platinum Service Award and have been named a Which? Best Buy plant supplier – endorsements that came from our customers, not our marketing team.

Frequently Asked Questions

What colour are Millennium sweet pea flowers?

Ruby red with purple undertones; the standards lean crimson-ruby, the wings lean violet-purple. The two tones shift and blend in different light, giving a stained-glass complexity. In bright sun, the ruby glows; in cloud, the purple comes forward.

Who bred Millennium?

Bred by D.M. Jones and introduced in 2000. It has been a popular exhibition variety since its release, classified in the red class by the NSPS and a regular at national shows.

How scented is Millennium?

Light: a 3 on the Parsons scale, and honest about it. The fragrance is clean and sweet but not room-filling. Millennium's strength is colour and form, not scent. For maximum fragrance, pair it with a Grandiflora like Matucana or Flora Norton – the Grandiflora adds the scent, Millennium adds the colour.

Is Millennium good for cutting?

Very – it is an exhibition-quality Spencer with long, straight stems. The colour holds well in water and the blooms last. Cut in the morning when the lowest flower on the stem is just opening and stand in clean water. Expect five or six days of good vase life.

Do sweet peas come back every year?

No – sweet peas are annuals. One season of flowers, then done. The perennial sweet pea returns each year but carries no scent and has smaller flowers. For the annual varieties, where the colour and fragrance are, fresh plants each spring is the way. See our sweet pea collection.
