Mammoth Melting Sugar

Family: Fabaceae Legume

Tender pods that seem to melt on the tongue—Mammoth Melting Sugar snow peas bring a lush, sweet snap with a distinctly smooth, succulent bite.

At maturity, the extra-large pods hang in generous arcs, offering a crisp, juicy texture that stays pleasantly delicate even as the harvest window opens. Grow them for fresh snacking, bright stir-fries, and vibrant additions to spring salads, where their mild sweetness and clean pea flavor shine.

Culinary Notes

Chef's Note

These extra-large snow pea pods earn their name: they crunch softly at first bite and then give way into something almost custardy, so they’re best treated like fresh produce rather than overcooked veg. Hit them with heat for only a moment—then finish bright (lemon/garlic or soy/butter) to keep that clean, sweet snap front and center.

Best Uses

quick 30–60 second stir-fries where the pods stay glossy and intact
raw snacking with flaky salt and citrus zest
spring salads—toss at the last minute so they keep their succulent bite
lightly steamed and finished with butter or olive oil to emphasize sweetness

Flavor Profile

mild, sweet pea flavor buttery snap with a melt-on-tongue texture crisp, juicy pod that stays delicate fresh green, lightly starchy sweetness

Kitchen Pairings

Frequently Asked Questions

What pest or disease commonly affects Pisum sativum (garden peas), and what should I do if I see it?

Watch for powdery mildew, which appears as a white-gray coating on leaves and can show up in humid weather. Improve airflow by spacing plants and removing heavily infected leaves, then apply a labeled sulfur-based fungicide early in the first signs. Also avoid overhead watering so foliage dries quickly.

How often should I water Pisum sativum during peak growth to keep pods developing?

During flowering and pod fill (roughly weeks 4–8), keep the soil consistently evenly moist—aim for about 1 inch of water per week, split into 2–3 waterings if it’s hot or windy. Let the top 1 inch of soil dry slightly between waterings, but don’t let the root zone go dry, because peas quickly drop flowers and slow pod development.

How can I tell when Mammoth Melting Sugar peas (Pisum sativum) are ready to harvest?

Start checking around 60–68 days after sowing, or when pods are fully formed and still glossy and tender. Pick sugar snap pods when peas inside are just beginning to swell (about the size of a small marble) and before pods turn tough or starchy. Harvest every 1–2 days during the peak window to keep plants producing.
