Pea, Mangetout 'Carouby de Maussane' Sugar Pod

Although not widely available commercially, the vintage, sugar pod type pea 'Carouby de Maussane' has been enjoying a small-scale renaissance among heritage vegetable enthusiasts.

The pods that are thin, flat and wide and grow to 12cm (5in) or so long, they are very sweet and tender. They are at their best harvested when the peas are barely showing, but remarkably they retain their flavour even when they reach a huge size and don't develop any fibre layer at any stage.
The vigorous vines grow 140 to 150cm (around 54in / 1.5m). Eight peas per pod is about average. Not that it makes much difference if you're eating the whole pod. The seeds are brown and dimpled.

The vine of 'Carouby de Maussane' are exceptionally beautiful. They are covered with beautiful lavender and purple flowers and the leaf axils are stained with dark purple. The flowers are borne in pairs and curl downwards, they change colour as they mature. Young flowers are a deep dusky pink, maturing through purple shades to a lovely sky blue. The wing petal, which is much less visible than on other pea varieties, is deep velvety maroon. The strong dark veining on the backs of the petals greatly adds to their attractiveness.
To be honest you could grow it in the flower border just for its beauty.

Originating in Maussane near Avignon in France, not only is the flavour superior, this beautiful plant has several unique or unusual traits and clearly differs from modern conventional peas. This heirloom is truly a gem.

Position:
Peas require a sunny, position with well-drained but rich soil with a neutral pH, so if yours is at all acidic, the ground should be limed a few weeks before sowing.
Ideally, the ground would be dug and manured the autumn before sowing, but if you have good garden soil, a thin dressing of good garden compost or well-rotted manure just before sowing is adequate. This will help to improve the soil’s moisture-retaining ability during hot, dry summers.

Sowing:
In well drained soil, peas can be sown outdoors in November, for an early crop.
In spring, wait until the soil is warm to the touch, which will be some time between the middle of March and the middle of May, depending on your soil and where you live. Putting a layer of fleece over the soil in early March will help warm up the soil by as much as a couple of weeks. Make successional sowings every two weeks.
An old gardeners saying that 'rows should be sown in a North to South direction' had me wondering for years – all became clear when I found this explanation - “Since peas are prone to powdery mildew, plant them in rows that run north and south so that each plant has maximum opportunity for the sun to burn off the dew.”

Sowing Indoors:
To grow an early crop, try sowing seeds in a length of old guttering. Drill drainage holes at regular intervals along the base. Fill to the top with seed compost and space the seeds about 7.5cm (3in) apart.
Place the guttering in the greenhouse or cold frame. Keep the compost moist and transplant into the garden once the seedlings have established. Dig out a shallow trench and gently slide the pea seedlings into it. Water and cover with cloches to encourage growth. Autumn and early spring sowings will benefit from cloche protection.

Sowing Direct:
Peas sown in cold, wet ground will rot so make sure the soil is warm. In early spring, cover the soil with polythene before sowing and then protect seedlings with fleece.
Sow seed in a single row 5 to 10cm (2 to 4in) apart, ensuring there is enough space for plant supports. Make a single V-shaped drill, 5cm (2in) deep, water the base of the drill and sow the peas. A second row can be added, as long as it’s 30cm (12in) away from the first drill.
It is important to have room to get between the rows to pick - 3ft is probably the minimum and 6ft is ideal. If using the latter spacing, a crop of radish or lettuce can be grown in the gap, to be harvested before you start picking the peas.
Water your peas well after sowing, and then leave them - except in very dry weather - until they flower, when they should have a really good soak to encourage good pod formation. Keep them weeded until well established.

Supporting plants:
All but the most dwarf varieties need support. Once peas have reached, 5 to 8cm (2 to 3in) in height and their tendrils begin to reach out for support, place supports next to plants. Use bamboo canes, pea sticks, trellis, netting, chicken wire or use any garden pruning that produces twiggy branches.

Harvesting:
Regular picking is essential for a truly fresh pea. The more you harvest, the more they will produce. Harvest from the bottom of the plant working upwards. Do not pull up the plant as the roots are full of nitrogen-fixing bacteria.

Culinary Use:
Best eaten fresh, eat raw or boil straight after picking. Serve with just a knob of butter and a sprig of mint from the garden. The tips of the vines and the top set of leaves of the pea plant are an Oriental delicacy. They can be served raw in salads, quickly cooked in stir-fries, or blanched and used in soups.
Peas can be stored in the crisper section of the refrigerator for 2 to 3 days. Freeze any excess pea harvest as quickly as possible because the sugar in peas turns to starch very quickly after picking, which destroys that precious sweetness.

Crop Rotation:
Peas are a useful part of the gardener's vegetable rotation. Cut off the stems at ground level, and allow the roots to rot down and release nitrogen back into the soil. The nitrogen can be taken up by the crop that follows them - usually a brassica such as cabbage.

Pea varieties
Peas come in two varieties: shelling and mangetout.
Shelling peas mature at different times. Earlies take around 12 weeks, second earlies take 14 weeks and maincrops take 16 weeks. While the slowest can take a month longer - they will then go on producing pods for about a month.
Shelling peas come in round and wrinkle-seeded varieties. Choose round seeds for hardiness and early sowings, and wrinkled for sweetness and summer sowings.

Mangetout is French for "eat it all" and comes from the fact that the whole pea - including the pod - is eaten. They are a frequent addition to stir-fry dishes. Other names include Snow Peas, Edible-podded peas, and Chinese sugar peas. They are without the hard wall to the pod that conventional 'wrinkled' peas have.
Mangetout and sugarsnap peas are eaten pods and all. The former never really develop proper peas, while the latter do, but slowly, which means that if you do not pick them regularly you can harvest the maturing peas and eat them as a normal variety. Both are without the hard wall to the pod that conventional 'wrinkled' peas have.
There is a lot to be said for growing these peas if you have limited space and perhaps limited patience for shelling peas.
