‘Sunset Buff’ Calendula, also known as pot marigold, is an annual plant prized for its soft, nuanced hues. It is a versatile choice for gardens, suitable for borders and containers, due to its continuous blooming and ease of cultivation. Its reliable performance makes it a popular addition to outdoor spaces.
Unique Charm of Sunset Buff Calendula
The ‘Sunset Buff’ variety distinguishes itself with a sophisticated color palette, moving beyond the typical bright oranges and yellows of common calendulas. Its petals unfurl in delicate shades of buff, apricot, and soft rose, often featuring subtle variations and undertones that shift with the light. The blooms are typically daisy-like, ranging from 3 to 4 inches wide, with some appearing as single or double forms, sometimes with contrasting centers.
Cultivating Sunset Buff Calendula
Site Selection and Soil
‘Sunset Buff’ Calendula thrives with at least six hours of full sun daily for optimal blooming. While it tolerates partial shade, too much shade reduces flower production. The plant prefers well-draining, moderately fertile soil, avoiding overly rich or wet conditions that hinder growth. A soil pH between 6.0 and 7.0 (slightly acidic to neutral) is generally preferred, though calendulas adapt to a wider range.
Planting and Watering
Calendula seeds can be directly sown outdoors in early spring after the last frost, or started indoors four to eight weeks prior for an earlier bloom. When direct sowing, plant seeds 1/4 to 1/2 inch deep, spacing them 6 to 12 inches apart. Seedlings emerge within 7 to 14 days when soil temperatures are between 70-75°F (21-24°C). After planting, water frequently to keep the soil consistently moist until established, but avoid waterlogging. Mature plants require less frequent watering, typically one to two inches per week, adjusting for rainfall.
Ongoing Care
Routine maintenance extends the blooming period of ‘Sunset Buff’ Calendula. Deadheading, which involves removing spent flowers with fingers or snips, encourages the plant to produce more blooms rather than setting seed. While calendula does not require heavy fertilization, incorporating compost or a balanced general fertilizer at planting can be beneficial, especially in poor soil. Pests like aphids or whiteflies can be managed by spraying with water or insecticidal soap. Ensuring good air circulation between plants helps prevent fungal diseases such as powdery mildew, and avoiding overhead watering is recommended.
Harvesting and Enjoying Your Blooms
Regularly harvesting ‘Sunset Buff’ Calendula flowers promotes continuous blooming and productivity. The best time to pick blooms is mid-morning after the dew has dried, when flowers are fully open; simply snip or pinch the head at its base. The blooms can be enjoyed as cut flowers, adding warm tones to indoor arrangements. Beyond their ornamental value, calendula petals are edible and can add color to salads or dishes. Historically, calendula has also been recognized for its medicinal properties, often used topically for skin irritations.
