Moss Rose has a variety of medicinal applications. Here are some of the potential benefits:
Important Note: You should not use it to make home remedies unless you are properly trained to do so.
Grow Moss Rose flowers in bright, direct, full sun. Select a planting location where they will receive six to eight hours of full sunlight.
The plants grow in partial sunlight. However, if they do not receive sufficient sunlight, the plant will fail to bloom.
Moss Rose plants are grown from seeds. Moss Rose seeds can be directly seeded into your flower garden or seeded indoors for transplanting later. For growing Moss Rose, an early, indoor start, translates into an earlier bloom.
Sow seeds early in the season and cover lightly with 1/8″ of fine garden or seed starting soil.
Seeds germination period, requires one to two weeks. For indoor starts, try a seedling germination mat.
Do not set out seedlings until after the last frost date in your area. Plants are susceptible to frost. The ideal plant spacing is ten inches apart.
Established plants can also be propagated by cuttings.
Days to Germination: 10 – 15 days.
Moss Rose flowers are easy to grow. Grow Moss Rose plants in full sun. Plants prefer average to poor soils. They prefer loose, sandy, or loam soil. A well-draining composition is important.
The final spacing is six to twelve inches apart. The plants tolerate a little overcrowding. This makes them good candidates to grow in containers.
Moss Rose plants are drought and heat tolerant. In the flower garden, watering is seldom needed. If growing in containers or hanging pots, allow the soil to dry between watering. Add a general-purpose, high nitrogen fertilizer when first planting, to help them to get a good start. Add a high Phosphorous fertilizer just before blooming. No other fertilizer applications should be needed for the season.
Moss Rose produces tough, long-lasting, rose-like blooms, in early summer. Pinch or deadhead spent flowers to promote more blooms.
Prune plants to create a fuller, neater appearance. Provide plenty of air circulation through the plant to help avoid fungal disease.
Plants are annuals that are very susceptible to frost. Cover them up whenever cold temperatures are expected.

Short and compact Moss Rose plants make the good candidates for flowerpots and containers on your patio or deck. And, their perky blooms will make you want to grow them there. They grow well in windowsill planters, too.
In addition to the normal steps for growing them, here’s how to care for them in a flowerpot or container:
The plants are almost maintenance free. Pruning is not necessary. However, you may want to remove the occasional damaged or broken stems and leaves.
Deadheading spent blooms is not required, either. However, you may want to remove them to improve plant appearance. If you leave them on the plant, you can harvest seeds for next year’s crop.
Aphids, gnats, and other insects can pose a problem. Treat with insecticide or repellents, as needed. Snails and slugs can also be a problem. See more on Snail and Slug Control.
Fungus diseases can occur. Use a general-purpose fungicide in humid weather, and when problems appear.
Stem and root rot can occur. This is a problem in wet soil. Avoid problems by planting in sandy, or other well-draining soil. A slightly elevated planting bed also helps to avoid this problem.
