'Turquoise Lagoon' Sweet Pea Seedlings

Turquoise Lagoon Sweet Peas

What a sublime beauty of a sweet pea! Turquoise Lagoon may well transport you straight to the Caribbean, with its pale pink buds opening lavender and changing gradually to the softest of blues, the colour of lapping waves or a picture-postcard tropical sunset.  It will even morph, from lavender to blue, when cut and arranged in a vase. Turquoise Lagoon is slightly shorter than most sweet peas, at 1.5m or so, but the scent is magnificent, and it's a prolific flowerer. As always with sweet peas, train them up an obelisk or trellis, guiding the young shoots in at first to help them find a foothold.

In Your Garden Design

Sweet peas are a cottage garden classic and Turquoise Lagoon will combine effortlessly in a mixed border with other favourites of the English garden, among them Cosmos, whose pastel-coloured flowers will bob and float prettily below a wigwam of sweet peas. Lavender, too, makes a lovely companion: a double whammy of scent and pinky purple hues. It's a good idea to grow a couple of varieties of sweet pea, for added interest in vases. Rich lilac Solitude would go well with Turquoise Lagoon, its more saturated shade providing a beautifully toning contrast. Remember not to let your sweet peas go to seed – keep picking them, and they'll go on and on producing more flowers right into autumn.

Plant Turquoise Lagoon Sweet Peas in well prepared, moist soil that ideally was enriched with organic matter the previous autumn (if you did not do it then, do it now!). Erect supports for the peas to climb up before planting. They can also be planted in pots of sufficient size - allow 6 litres per plant - and with an ideal planting medium of 50% compost, 40 %top soil and 10% well rotted manure. General purpose compost will do however but produces fewer flowers.

The principal requirement is enough water - Sweet Peas are thirsty and hungry plants. They can cope with a little shade but flower better in full sun.

Space each plant about 30 cm apart and about 5 cm from its support. The hole should be deep enough to accommodate the longest root and the soil should come up to the level of the first side shoot. Use wire/netting/twine between the supports so that the Sweet Pea can climb naturally. You will still need to tie them in to the frame. They grow fast, so check every ten days or so.

Water well; the soil around sweet peas should never dry out. As the flowers develop pick them, and then pick again, otherwise they start to form seedpods and will stop flowering altogether. Keep tying in and picking for as long as you can. Perfectionists will remove the curling tendrils which grip other stems and can result in flowers with wiggly stems and also will remove side shoots. see the website for more advice on training sweetpeas.

By all means apply a high potash and phosphate fertiliser during the growing season. (Sweet Peas actually fix nitrogen from the air into the soil so you don't need more of that.) Home-made comfrey liquid is perfect or Tomorite will do especially if you are on a sandy soil.

Did You Know?

Bred by sweet pea supremo Dr Keith Hammett in Auckland, New Zealand, this modern hybrid is a cross between Lathyrus odoratus and L. belinensis, creating a new category of sweet peas known as shifters.
