Chrysanthemum × morifolium

Chrysanthemum × morifolium, commonly known as mums, are popular flowering plants cultivated for their vibrant and diverse flower colors and forms. They are herbaceous perennials, typically grown as annuals in many climates due to their sensitivity to frost. Mums are characterized by their bushy growth habit and composite flower heads, which come in various shapes like daisy-like, pompon, and spider. While primarily outdoor plants, they are often brought indoors for short periods to enjoy their blooms, but they require specific conditions to thrive indoors long-term. People grow them for ornamental purposes, adding color to gardens and homes, and for cut flowers.

❓ Frequently Asked Questions — Comparing These Plants

Cape Marigold

What are the light requirements for Cape Marigold?

Cape Marigolds thrive in full sun, requiring at least 6 hours of direct sunlight each day to produce abundant blooms. Insufficient light will result in fewer flowers and leggy growth. When grown indoors, place them near a south-facing window where they can receive the most intense sunlight. If natural light is limited, supplement with grow lights to ensure adequate illumination.

Cape Marigolds need full sun, at least 6 hours daily, to bloom profusely. Plant in well-draining soil, either in the garden or in containers. Water regularly, allowing the soil to dry slightly between waterings; avoid overwatering. Fertilize monthly during the growing season with a balanced fertilizer diluted to half strength, or a fertilizer formulated for blooming plants. Deadhead spent flowers regularly to encourage more blooms.

How do I propagate Cape Marigold?

Cape Marigolds can be propagated through stem cuttings. Take a 4-6 inch cutting from a healthy stem, removing the lower leaves. Dip the cut end in rooting hormone and plant in well-draining potting mix. Keep the soil moist and provide bright, indirect light. Roots should develop in a few weeks.

Mum

What are the light requirements for Mum?
