Marigold ‘Taishan Orange’ is a highly regarded African marigold (Tagetes erecta) known for its vibrant display and adaptability. Gardeners frequently select this variety for its consistent performance, striking visual appeal, and long blooming period. Its easy care makes it a favored choice for adding continuous color to various landscapes.
Distinctive Features
The ‘Taishan Orange’ marigold features vivid, true orange blooms, which give the plant its name. These large, ball-shaped flowers are fully double, creating a dense, pom-pom-like appearance. Each bloom measures 3 to 4 inches in diameter. Its sturdy stems are 15% thicker than many other varieties, supporting the large flowers without bending or breaking.
This marigold maintains a compact, uniform growth habit, typically reaching 10 to 12 inches tall and spreading 8 to 10 inches. Dark green, fern-like foliage provides a rich backdrop for the bright orange blossoms. The plant blooms prolifically from early summer through mid-fall, ensuring a sustained period of color in the garden.
Planting and Growing Guide
‘Taishan Orange’ marigolds thrive in full sun, ideally six or more hours of direct sunlight daily, but can tolerate partial shade. Well-draining soil is important, and while they are not particularly sensitive to soil type or pH, a pH between 6.0 and 7.0 is recommended. Amending the soil with compost enhances its structure and fertility. Plant after the last frost, as these marigolds are sensitive to cold temperatures.
Seeds can be started indoors six to eight weeks before the last frost date or directly sown outdoors once frost danger has passed. When planting seedlings, space them 8 to 10 inches apart to allow for proper air circulation and growth. After planting, a thorough initial watering helps the plants establish. Consistent moisture is beneficial during this early stage.
Ongoing Care
Consistent watering ensures the soil remains evenly moist but not waterlogged. Allowing the top inch or two of soil to dry out between waterings helps prevent root issues. While generally low-maintenance, a light application of a balanced or bloom-boosting fertilizer every 4 to 6 weeks can support vigorous growth and abundant flowering. Marigolds typically do not require heavy feeding.
Regular deadheading, removing spent blooms, encourages the plant to produce more flowers throughout the season rather than expending energy on seed production. This practice also helps maintain the plant’s tidy appearance. ‘Taishan Orange’ marigolds are known for their hardiness and resistance to many common garden pests and diseases. Providing good air circulation through proper spacing can help prevent fungal problems, though spider mites or thrips may occasionally occur.
Garden Uses and Benefits
‘Taishan Orange’ marigolds are adaptable for a range of garden applications due to their compact size and uniform growth. They perform well in mass plantings, as border edging along pathways or garden beds, and in containers like pots and window boxes. The vibrant orange blooms attract beneficial insects, including bees and butterflies, contributing to a healthy garden ecosystem.
Beyond their aesthetic appeal, ‘Taishan Orange’ marigolds offer practical advantages. They are generally considered deer resistant. Some marigold varieties, including African marigolds, deter certain soil nematodes through compounds released from their roots, which can benefit nearby plants.
