Marshmallow: A Hardy Herb with Edible Leaves, Flowers, and Roots
Marshmallow is a hardy perennial herb in the mallow family. It grows soft green leaves, pale pink to white flowers, and useful roots that can be harvested once the plant is well established. Marshmallow does best in full sun with consistently moist soil. You can find growing details for marshmallow in the Seed to Spoon app to help you plan when to plant, water, harvest, and save seeds.
Why Grow Marshmallow?
Marshmallow is a great plant for gardeners who want a useful herb that can come back year after year. It is also a pretty garden plant, with tall stems and gentle flowers that fit well in herb gardens, pollinator gardens, and damp spots where many herbs struggle.
Key Benefits of Growing Marshmallow:
✅ Perennial Herb – Plant it once and it can return for years in the right conditions.
✅ Edible Parts – Young leaves, flowers, and roots can be used in simple kitchen preparations.
✅ Pollinator Friendly – Summer flowers can attract bees and other helpful insects.
✅ Loves Moist Soil – A good choice for garden areas that stay evenly moist.
✅ Seed Saving – Let seed pods dry on the plant and save seeds for future planting.
How to Grow Marshmallow from Seed
Marshmallow can be grown from seed, but spring-planted seeds sprout best after a cold period. You can also direct sow outdoors in fall and let winter do the chilling for you.
1. Start Seeds Indoors or Sow in Fall
📅 When to Start Indoors: 6-8 weeks before your last spring frost, after 3-6 weeks of cold stratification.
🌱 How to Sow: Plant seeds about 1/4 inch deep in seed-starting mix.
🌡 Germination Time: 10-21 days after the cold period.
💧 Watering: Keep the soil evenly moist while seeds sprout.
2. Transplanting Outdoors
🌿 When to Plant: Move transplants outdoors after frost, or direct sow in fall before the ground freezes.
☀️ Sunlight Needs: Full sun is best, but marshmallow can handle some afternoon shade in hot areas.
📏 Spacing: Give each plant room to grow tall and wide. One plant per square foot is a good starting point.
Caring for Marshmallow
🌿 Watering: Keep soil consistently moist, especially while plants are young. Do not let container plants dry out completely.
🌱 Fertilizing: Mix compost into the planting area before planting. Feed lightly in spring with compost or a balanced organic fertilizer. Avoid too much nitrogen, which can cause lots of leaves but fewer flowers and roots.
✂️ Pruning: Remove dead stems and leaves as needed. Cut back old growth at the end of the season or in early spring.
How to Harvest and Use Marshmallow
Harvest young leaves once the plant is established. Pick flowers in summer. For roots, wait until fall of the second year or later so the plant has time to grow strong.
To eat marshmallow: Wash the young leaves and flowers. Eat a few young leaves raw, or cook the leaves like spinach in soup or stew. Wash the roots, slice them, and dry them for tea. You can also simmer sliced root in water to make a thick syrup.
Common Marshmallow Pests
Marshmallow can sometimes attract aphids, Japanese beetles, leaf miners, leafhoppers, mealybugs, stinkbugs, thrips, and whiteflies. Check the undersides of leaves often. If pests show up, remove heavily damaged leaves, spray plants with water, and use organic options like insecticidal soap when needed.
