Calendula Seeds,
Pink Surprise

Pink Surprise calendula grows best in cooler weather and can be planted in both spring and fall. In colder climates, sow seeds in early spring as soon as the soil can be worked. In warmer regions, fall sowing will provide a vibrant display through the cooler months. Calendula can tolerate light frost and may continue to bloom into early winter in milder climates​.

Pink Surprise calendula can be grown from seed either directly in the garden or started indoors. For direct sowing, plant seeds about 1/4 inch deep in well-drained soil and cover lightly. When starting indoors, begin 4–6 weeks before the last frost. Maintain a soil temperature of 65–70 F for optimal germination. Space seedlings about 10 inches apart once they have sprouted to allow for good air circulation​.

Calendula prefers full sun but can tolerate partial shade, especially in hot climates. It grows best in well-draining soil that is not overly fertile. Regular watering is important until the plants are established, after which they can tolerate occasional drought. Deadheading spent blooms will encourage continuous flowering, and pinching back the plants can promote bushier growth​. Calendula self-seeds readily, so allowing some flowers to go to seed can provide a natural source of new plants for the following year​.

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.
