Calendula Seeds,
Snow Princess

Snow Princess calendula grows best in cooler weather and can be planted in both spring and fall. For early spring blooms, sow seeds indoors 6-8 weeks before the last frost and transplant them outdoors once the danger of frost has passed. In warmer climates, seeds can be sown directly outdoors in the fall for winter blooms.

Sow Snow Princess calendula seeds about 1/4 inch deep in well-drained soil. Seeds can be sown directly into the garden after the last frost or started indoors for earlier blooms. Maintain a consistent soil moisture level until the seeds germinate, which typically takes 7-14 days. Space the plants about 10 inches apart to allow adequate air circulation​.

Calendula prefers full sun but can tolerate partial shade, especially in hot climates. It thrives in light, well-drained soil and requires moderate watering. Once established, Snow Princess is relatively drought-tolerant. Deadheading spent flowers will encourage continuous blooming throughout the season. Pinching back young plants can promote bushier growth and prevent legginess.

Plants easily self-sow the following spring. If growing more than one variety of calendula, you will need to isolate by 1/4 mile from any other calendula varieties, or you can use caging techniques. Seeds are easy to save; the heads turn brown and seeds can easily be harvested in fall. Keep in a cool, dry, dark place until next spring.
