Scent from Heaven Angel of Purity Dianthus - 1 Gallon

Dianthus 'Angel of Purity' is a compact, mat-forming herbaceous perennial belonging to the Caryophyllaceae (carnation) family. It is part of the Scent from Heaven series, a premium collection bred by Dr. Keith Hammett and selected for outstanding fragrance, exceptional flower quality, and strong garden performance. The blooms are frilly, semi-double to fully double, and a pristine pure white — occasionally displaying a subtle faint pink eye at the center — and are produced in loose clusters held on upright stems above the foliage. The flowers emit a rich, classic clove-like scent that intensifies on warm days, making it one of the most fragrant dianthus cultivars available. The foliage forms a tight, tidy mound of fine, grass-like, silvery gray-green to blue-green leaves that is evergreen in mild climates, providing structure and year-round visual interest even when the plant is not in flower.

Dianthus 'Angel of Purity' is a reliably cold-hardy perennial suited to a wide range of climates. It has been trialed and proven in both cold and humid regions, making it well suited to the varied conditions found throughout Southern Oregon and Northern California.

• USDA Hardiness Zones: 4 to 9
• Tolerates hard frosts and cold winters down to Zone 4
• Performs well in warm summers and humid conditions
• Drought tolerant once fully established in the garden
• Heat tolerant; adapts well to warm, dry inland valley climates
• Evergreen foliage persists through mild winters, maintaining garden interest year-round

For the best flowering performance and most compact, healthy growth habit, plant Dianthus 'Angel of Purity' in a location that receives full sun. While it can tolerate partial sun, reduced light will result in fewer blooms and a less tidy mounding form.

• Ideal: Full sun — 6 or more hours of direct sunlight per day
• Acceptable: Partial sun — at least 4 to 6 hours of direct sun, with afternoon shade in the hottest inland climates
• Avoid deep or full shade, which causes weak, leggy growth and significantly reduces flowering
• In the hottest inland areas of Northern California, a bit of afternoon shade can help protect blooms and extend the flowering season through summer

Dianthus 'Angel of Purity' thrives in soils that are loose, well-draining, and moderately fertile. Like most dianthus, it performs best in slightly alkaline to neutral soil and is intolerant of waterlogged or heavy clay conditions that promote root rot.

• Preferred soil type: Loose, sandy, or loamy, well-draining soil
• Soil pH: Slightly alkaline to neutral — ideally 6.5 to 7.5
• Amend heavy clay soils with coarse sand, perlite, or grit before planting to improve drainage
• Add garden lime to acidic soils to raise pH to the preferred slightly alkaline range
• Avoid soggy, waterlogged, or poorly drained locations; standing moisture is the primary cause of decline
• Moderate organic matter content is beneficial, but overly rich soils can produce lush foliage at the expense of flowers

Dianthus 'Angel of Purity' has moderate water needs and becomes quite drought tolerant once established. The key to success is allowing the soil to partially dry out between waterings — consistently wet soil is the most common cause of root rot and plant decline.

• Newly planted: Water regularly to keep the root zone consistently moist while the plant establishes — typically the first 4 to 6 weeks after planting
• Established plants: Water deeply but infrequently; allow the top inch or two of soil to dry out between waterings
• In the dry summers of Southern Oregon and Northern California, deep watering every 7 to 10 days is generally sufficient for established plants
• Always water at the base of the plant; avoid overhead watering, which can promote fungal diseases on the foliage and flowers
• Reduce watering frequency in winter when the plant is less actively growing
• Good soil drainage is essential — never allow the plant to sit in standing water

Dianthus 'Angel of Purity' is not a heavy feeder, and over-fertilizing — particularly with high-nitrogen fertilizers — can encourage excessive leafy growth at the expense of fragrant blooms. A light, balanced fertilizing program is all that is needed to keep this perennial performing at its best.

• Apply a balanced, slow-release granular fertilizer (such as a 10-10-10 formula) at the start of the growing season in early spring
• A light application of a low-nitrogen, bloom-boosting fertilizer (higher in phosphorus) in mid-spring can promote more prolific flowering
• Avoid high-nitrogen fertilizers, which promote lush, floppy foliage and fewer flowers
• Amending the soil with compost at planting time reduces the need for supplemental feeding
• Container-grown plants benefit from a diluted balanced liquid fertilizer applied every 4 to 6 weeks through the active growing season
• No fertilizing is needed in late summer or fall — allow the plant to slow naturally before winter

Dianthus 'Angel of Purity' is a low-maintenance perennial, but a few simple grooming practices will keep plants looking their best and encourage the longest possible bloom season. Deadheading is particularly important for maximizing the number of flowers produced throughout the season.

• Deadheading: Remove spent blooms promptly and regularly throughout the season to redirect the plant's energy into producing new flower buds and to extend the bloom period from spring through fall
• Shearing: After the first main flush of spring bloom, lightly shear the plant back by one-third to encourage a tidy habit and promote a strong second flush of flowers
• Spring cleanup: In late winter or early spring, tidy up the mound by removing any winter-damaged or brown foliage before new growth begins
• Avoid cutting back into old woody stems at the base, as dianthus can be slow to regenerate from severely hard-pruned crowns
• Division every 2 to 3 years in early spring or early fall helps rejuvenate older clumps and maintains vigorous flowering

1. Select a planting site with full sun and well-draining soil. Avoid low spots where water collects after rain.
2. Prepare the planting bed by loosening the soil to a depth of 12 to 16 inches. Amend heavy clay or compacted soils with coarse sand, perlite, and compost to improve drainage and fertility.
3. If your soil is acidic, test the pH and add garden lime as needed to bring it to a slightly alkaline level of 6.5 to 7.5.
4. Dig a planting hole slightly wider than the root ball but no deeper — the crown of the plant should sit at or slightly above the surrounding soil level to prevent crown rot.
5. Remove the plant from its container and gently loosen any circling roots before placing it in the hole.
6. Backfill with the amended soil, firming gently around the roots to eliminate air pockets. Do not bury the crown.
7. Water thoroughly after planting to settle the soil around the roots.
8. Apply a light layer of coarse gravel or bark mulch around (but not over or touching) the crown to help retain soil moisture and moderate soil temperature — avoid dense mulch directly against the stems, which can promote rot.
9. Space plants 10 to 12 inches apart for a solid edging effect, or 12 to 18 inches apart when used in mixed borders.

Dianthus 'Angel of Purity' pairs beautifully with a wide range of perennials, ornamental grasses, and shrubs that share its preference for full sun and well-draining soil. Consider these companion plants for cohesive, season-long garden compositions:

• Lavender (Lavandula spp.): Shares the same love of sun, sharp drainage, and slightly alkaline soil, and the combination of white and purple is classically elegant
• Catmint (Nepeta spp.): A low-growing, blue-flowered companion that blooms at the same time and thrives in similar conditions
• Salvia (Salvia nemorosa): Upright purple or blue flower spikes contrast beautifully with the white, low-mounding dianthus
• Ornamental grasses (Festuca glauca): Blue fescue's similar silvery blue-green coloring and compact form makes a harmonious textural pairing
• Creeping phlox (Phlox subulata): Another low-growing, spring-blooming perennial that complements the color and habit of Angel of Purity
• Sedum (Hylotelephium spp.): Succulent sedums share drought tolerance and provide late-season color as a contrast to the dianthus's earlier bloom
• Veronica (Veronica spicata): Spiky blue-purple flower spikes create height contrast and bloom in sync with the main dianthus season
• Roses (Rosa spp.): Planted at the feet of roses, Angel of Purity fills the lower garden layer with fragrant white blooms while the roses provide height and structure above

Dianthus 'Angel of Purity' is generally a robust and disease-resistant perennial, particularly when grown in the right conditions. The vast majority of problems arise from poor drainage, overhead watering, or overly rich soil. The Scent from Heaven series has been specifically selected for improved disease resistance compared to older dianthus varieties.

• Crown rot / root rot: The most common issue, caused by excessive moisture or poor drainage around the crown. Plant in well-draining soil and avoid overwatering to prevent. Ensure crowns are never buried too deeply.
• Fusarium wilt: A soil-borne fungal disease that causes wilting and yellowing. Prevent by planting in well-draining, non-compacted soil and avoiding overhead irrigation.
• Powdery mildew: Can appear on foliage in humid conditions with poor air circulation. Space plants properly and avoid wetting the foliage when watering.
• Aphids: Occasionally cluster on new growth and flower buds. Dislodge with a strong spray of water or treat with insecticidal soap if populations are high.
• Spider mites: More likely during hot, dry weather. Improve air circulation and maintain consistent soil moisture to discourage infestations.
• Slugs and snails: Can damage foliage and flowers in moist conditions. Use iron phosphate bait or diatomaceous earth around plants as needed.
• Deer and rabbit resistance: Generally considered deer resistant due to its strong fragrance, though no plant is completely deer-proof under all conditions.

Dianthus 'Angel of Purity' is an excellent choice for container gardening, bringing its beautiful fragrant blooms and tidy silver foliage to patios, decks, entryways, and balconies throughout the long growing season.

• Choose a container with ample drainage holes — excellent drainage is essential to prevent root rot
• Use a well-draining potting mix; add perlite or coarse grit to standard potting soil to improve drainage if needed
• A container at least 10 to 12 inches in diameter gives the roots adequate room to develop and helps buffer soil temperature fluctuations
• Place containers in a location receiving 6 or more hours of direct sunlight daily for best flowering performance
• Container plants dry out faster than in-ground plantings — check soil moisture regularly and water when the top inch of soil feels dry
• Fertilize container plants with a diluted balanced liquid fertilizer every 4 to 6 weeks during the active growing season
• In colder climates (Zone 4 to 6), move containers to a sheltered, frost-protected location in winter or overwinter indoors in a cool, bright spot
• Refresh or replace potting mix every 1 to 2 years to replenish nutrients and maintain good soil structure

Despite its refined, delicate appearance, Dianthus 'Angel of Purity' is a valuable plant for supporting garden wildlife, especially pollinators active during its long spring-to-fall bloom season.

• Bees: Honeybees and native bees are strongly attracted to the nectar-rich flowers, especially during the primary spring bloom period
• Butterflies: The open, accessible flower structure and generous nectar supply make it a reliable butterfly attractant throughout the season
• Other beneficial insects: The flowers attract a range of beneficial insects, helping support a healthy, balanced garden ecosystem
• Deer resistance: The strong clove fragrance of the foliage and flowers deters deer browsing in most garden situations
• Toxicity: Not known to be significantly harmful to humans, dogs, or cats when handled normally, though ingestion of plant material in quantity should be avoided
