Aromatic perennial herb with glaucous leaves and sunny blooms
Rue Seeds introduce a classic perennial herb celebrated for glaucous, blue-green foliage and clusters of sunny, yellow summer flowers. Often known as Common Rue, Herb-of-Grace, or Garden Rue, this aromatic bitter herb brings structure to herb garden borders, gravel schemes, and xeriscape plantings. The long flowering display supports biodiversity, offering nectar and shelter for pollinating insects, and acting as a butterfly host plant for swallowtail caterpillars. Naturally deer resistant and noted as a cat deterrent plant, it suits mixed plantings where resilience and fragrance are valued.
With a preference for full sun and well-drained soil, plants raised from Rue Seeds form compact, heat- and drought-tolerant bushes with tidy, easily pruned outlines. Sowing can be timed after the last frost; in mild climates autumn sowing may be possible, aiding steady establishment. As a container-suitable choice, Ruta can thrive in pots on patios as well as in open beds, maintaining the blue-green foliage that contrasts attractively with nearby plantings. The flowers appear over an extended season, enhancing a flowering display that draws beneficial insects throughout warmer months.
From an herb garden perspective, Rue Seeds provide a versatile option for companion planting and traditional culinary uses, where small amounts of foliage have long been used to flavor select dishes. Growers seeking true-to-type Ruta graveolens seeds will appreciate the characteristic scent, the essential oil heritage, and the manageable size suited to spaces needing a tough, evergreen-like presence. Alongside Common Rue Seeds and other Ruta Seeds, this collection focuses on reliable germination and straightforward rue plant care, supporting Ruta graveolens cultivation for borders, pathways, and containers.
Ruta graveolens (Common Rue)
This navigator links related herb categories, placing rue within the wider collection. From aromatic and culinary types to drought tolerant and perennial selections, it connects complementary groups and classic staples such as thyme, sage, and oregano. It supports comparisons of growth habits, flavors, and traditional uses, and helps with planning plantings from seed after the last frost in cooler conditions or during mild seasons when temperatures remain reliably warm.
Ruta graveolens (Common Rue)
Ruta graveolens yields a hardy, heat- and drought-tolerant perennial herb with blue-green foliage and yellow summer flowers. For best rue plant care, grow in full sun (tolerates light shade) and well-drained, light to moderately fertile soil; it copes with poor, dry, even alkaline conditions. Water sparingly once established, as overly wet roots can cause decline. For Ruta graveolens cultivation, start seeds indoors in early spring or sow outdoors after the last frost; in mild climates, autumn sowing may be possible. Space plants 45–60 cm apart to allow an upright, bushy habit, making this aromatic bitter herb well suited to herb garden borders and xeriscapes.
- Container-suitable: Thrives in pots with sharp drainage; use a gritty mix and avoid overwatering.
- Pollinator-friendly: Summer blooms support beneficial insects; foliage is a swallowtail caterpillar host—some leaf nibbling is normal.
- Edible: Traditionally grown as an aromatic bitter herb; culinary use is very sparing due to intense flavour; verify suitability before use.
- Ornamental: Dense blue-green foliage and small yellow flowers suit borders and xeriscapes; generally deer resistant and often noted as a cat-deterrent plant.
- Germination tips: Sow on or barely cover; keep 15–21°C with steady, light moisture—sprouting may take 2–4 weeks.
- Pruning rue bush: Lightly trim after flowering to keep compact; avoid cutting into old wood; consider gloves as sap may irritate skin.
How do I grow rue from seed (Ruta graveolens)?
Start Ruta graveolens from seed indoors in early spring, or sow outdoors after the last frost; in mild climates, autumn sowing may be possible. Use a free-draining seed mix and sow on the surface or barely cover, as light can aid germination. Keep evenly moist, not wet, and provide warmth and bright light. Germination time is often 2–4 weeks, occasionally longer. Pot on seedlings as they handle, then harden off before planting in full sun (tolerates light shade). Choose well-drained, light to moderately fertile soil; rue accepts poor, dry, even slightly alkaline sites. Once established, this drought- and heat-tolerant perennial herb needs only modest watering.
How tall does rue get, and how should I space plants?
Expect mature plants to reach about 60–90 cm tall, forming a rounded, woody-based shrub with fine, blue-green foliage and small yellow summer flowers. Space rue 45–60 cm apart to allow airflow and the plant’s natural shape. Growth is denser if lightly pruned after flowering; avoid cutting into very old wood. Situate along herb garden borders or xeriscape beds with excellent drainage. Because the sap can irritate skin, many gardeners wear gloves when pruning or handling in bright sun.
Does rue grow well in pots?
Rue grows reliably in containers. Select a pot at least 25–30 cm wide with generous drainage holes, and fill with a gritty, well-drained mix. Position in full sun and water deeply, then allow the top couple of centimeters to dry before watering again; reduce feeding, as rich soils encourage lanky growth. In prolonged heat, slightly more frequent watering helps, provided drainage is sharp. Light pruning keeps a compact form, and raising the pot off saucers prevents waterlogging in cool, wet spells.
Is rue edible and how is it used?
Rue is a strongly aromatic, bitter herb historically used in very small amounts. While technically edible, its essential oils are potent, and larger quantities can cause stomach upset or photosensitivity; it is not suited to regular consumption. If used at all, only a tiny pinch of young leaf may be added to robust dishes for a distinctive, resinous note. Handling can irritate skin in bright sun, and it should be avoided during pregnancy. Many growers treat rue primarily as an ornamental and companion plant.
Is rue good for pollinators and wildlife?
Clusters of yellow summer flowers provide nectar and pollen for a range of small pollinators, and the plant’s open structure encourages beneficial insects in the garden. In some areas, rue can serve as a host for swallowtail caterpillars, so occasional leaf nibbling is normal. To support wildlife, avoid broad-spectrum pesticides near flowering stems and allow a few blooms to persist. Its long season in full sun and lean soil makes it a useful resource in low-input plantings.
Does rue deter cats, and is rue deer resistant?
Many gardeners find the pungent scent of rue helps discourage cats from lounging or digging, though effectiveness varies by animal and site. As a deer resistant herb, rue’s bitter, aromatic foliage is generally unappealing to browsing wildlife, yet no plant is completely deer-proof, especially in lean times. For best results as a deterrent, site plants where aroma is most noticeable and combine with other strategies. Place away from narrow paths to reduce incidental contact with the sap.
Seeds are sourced from vetted producers and supplied in accordance with applicable phytosanitary, purity, and labeling standards. Batches are cleaned, tested for germination, and packed to maintain traceability and lot integrity. Growing and handling guidance is general and may vary with microclimate, soil, hardiness zone, and hemisphere; local conditions may affect best practice.

Aromatic perennial herb with glaucous leaves and sunny blooms
Rue seeds (Ruta graveolens) yield a compact, aromatic perennial with blue‑green, glaucous foliage and clusters of small yellow flowers. Sow indoors 6–8 weeks before the last frost or outdoors once soil has warmed; press seeds lightly into the surface, as light aids germination. Maintain gentle, even moisture at 18–22°C until sprouting, which typically occurs in 7–28 days. Provide full sun and sharply drained, moderately fertile soil; once established, plants are drought tolerant and suit dry borders, gravel gardens, and herb plantings. Space 30–45 cm; mature height is usually 45–75 cm with a rounded habit. The fine, lacy texture and late spring to summer blooms support garden biodiversity and visual interest. Handle with care, as foliage may cause skin sensitivity in bright sunlight; ingestion is not advised. In colder climates it may behave as a short‑lived perennial, while in mild conditions it can persist for several seasons. This variety forms part of the wider Herbs Seeds category.
