This curated selection of St. John’s Wort Seeds highlights the classic wildflower character of this herbaceous perennial. Renowned for bright, starry yellow blooms with brush-like stamens, it brings a generous flowering display across the warm months. Botanically Hypericum perforatum, this compact Hypericum forms tidy mounds that support biodiversity; the bee friendly flowers are valuable to a wide range of pollinating insects. Known variously as St John’s Wort, Saint John’s Wort, and Hypericum, it suits naturalistic planting schemes and traditional herb borders alike, balancing ornamental charm with resilience.
As a low maintenance herb, it thrives in full sun to light shade and adapts well to mixed borders, cottage garden plant settings, rock garden corners, and wildflower meadow edges. The fine-textured foliage and abundant buds offer continuity, with fresh flushes that keep the flowering display lively. This category of St. John’s Wort Seeds includes options for containers, where the bushy habit remains neat on patios or balconies, and for larger spaces that benefit from naturalizing plants. Whether chosen as Hypericum seeds for a pollinator garden or as perennial herb seeds for a classic herb border, St. John’s Wort Seeds reward with enduring structure and luminous blooms.
For straightforward seed propagation, sow indoors from late winter to spring with a brief cool period, or direct sow after last frost; in mild climates, autumn sowing may be possible. This approach helps establish sturdy seedlings that settle quickly and flower reliably in the second season. With thoughtful placement and modest care, St. John’s Wort Seeds mature into a durable, herbaceous perennial and a yellow flowering herb that harmonizes with grasses and companions, enriching habitat while sustaining a long-season flowering display.

Hypericum perforatum is a hardy herbaceous perennial grown from seed that thrives in full sun to light shade and well-drained, moderately fertile soil, tolerating sandy or gravelly sites. Keep the seedbed evenly moist during establishment; once rooted, plants are relatively drought tolerant and low maintenance. Start indoors from late winter to spring with a brief cold period, or direct sow after the last frost; in mild climates, autumn sowing may be possible. Seeds are light-sensitive: surface sow and do not cover—germination often improves with light exposure and a cool stratification. Space plants 30–45 cm; mature height is typically 30–60 cm, producing bright yellow flowers suited to herb borders, cottage plantings, and naturalizing in sunny areas.
St. John’s Wort (Hypericum perforatum) is an herbaceous perennial that’s straightforward from seed with a light-touch approach. Use a fine, well-drained seed compost and surface sow seeds, pressing them gently to ensure contact; covering is usually unnecessary as light can aid germination. Mist to keep the top layer evenly moist, not waterlogged, and provide bright light with good airflow. Once seedlings show true leaves, prick out carefully into small modules. Transplant to their final position after they’re sturdy and weather has settled, keeping spacing in mind to suit mature size.
Sow indoors from late winter to spring and set out after the last frost when growth is robust, or direct sow outdoors once the soil has warmed and frost risk has passed. In mild climates, autumn sowing may be possible for natural winter chilling. For borders, cottage garden plantings, or a wildflower meadow effect, space plants about 30–45 cm (12–18 in) apart. Expect a compact habit roughly 30–60 cm (12–24 in) tall once established, though growth varies with site conditions, soil fertility, and light exposure.
Cold stratification isn’t always essential, but a brief cold, moist period often improves and evens out germination for Hypericum seeds. Many growers give 2–4 weeks of chilled, slightly damp medium to mimic winter. After sowing, keep moisture steady and provide light; tiny seeds are best left uncovered or only dusted with vermiculite. Germination commonly starts in 2–6 weeks, though some seeds may be slower. Cooler to mild spring conditions suit them well; avoid high heat and avoid the compost drying out between gentle waterings.
A well-drained, moderately fertile soil is ideal; this perennial herb seed tolerates sandy or gravelly conditions and copes better with lean soils than with heavy, waterlogged ground. Choose full sun for the most flowers on this yellow flowering herb, though it remains light shade tolerant, especially where afternoons are intense or sites are dry. Once established, plants can be relatively low maintenance and show some drought tolerance, making them at home in an herb border, rock garden, or naturalizing scheme where drainage is reliable.
Container growing suits St. John’s Wort if you use a pot with ample drainage and a gritty, well-drained mix. Plant one seedling per roomy container to allow a balanced root system and avoid overcrowding. Water thoroughly but let the top of the mix dry slightly between waterings, as constant saturation can cause setbacks. Provide full sun to light shade and feed sparingly during active growth. Light pruning after flowering helps maintain shape and encourages fresh shoots, keeping potted plants compact and tidy.
Yes. The bright yellow, pollen-rich blooms are attractive to bees and other beneficial insects, adding value to a pollinator garden through the main flowering period. To support visitors, allow a portion of plants to bloom freely and avoid broad-spectrum pesticides nearby. Deadhead if you wish to prolong display, or leave some spent flowers to mature if gentle self-seeding is welcome in naturalizing plantings. Grouping several plants at the recommended spacing can create a visible nectar resource that’s easy for pollinators to find.
Seeds are sourced from audited suppliers and compliant with applicable seed health and labeling standards. Lots are tested for germination and purity; any treatments and origin are declared on product pages, which carry batch-specific instructions. Cultivation guidance here is general and may vary with microclimate, soil, hardiness zone, and hemisphere. Availability, importability, and packaging may be subject to local regulations and seasonal constraints (e.g., after last frost in cooler areas).
St. John’s Wort seeds (Hypericum perforatum) grow into a hardy perennial with clouds of bright, starry yellow blooms and showy stamens through early to mid-summer. This sun-loving herb thrives in well-drained soils and copes with lean conditions once established, forming bushy clumps suited to borders and naturalistic plantings. Sow thinly on the surface, as the tiny seeds need light to germinate; press in gently without covering. A brief chill period can improve germination. Start indoors 6–8 weeks before the last frost, or direct sow after the soil warms; in mild climates, autumn sowing may be possible. Transplant when seedlings are sturdy and the danger of frost has passed. Plants typically reach 40–90 cm, attract pollinators, and may self-seed; deadhead spent flowers if containment is preferred. This species is widely grown in herb gardens for its ornamental value and traditional uses, and is part of the broader Herbs Seeds range.
