Introduction
The ferncliff rusty dahlia is a captivating ball-form dahlia hybrid known for its moody, dusky tones and outstanding performance in both gardens and bouquets. Hybridized in British Columbia by the Jacks of Ferncliff Gardens, this variety consistently draws praise for its reliable bloom production, rich coloration, and elegant form .
What Is Ferncliff Rusty?
Ferncliff Rusty is a ball dahlia variety featuring medium-sized blooms, roughly 3 to 3½ inches in diameter, often described as rusty red or coral-orange with subtle raspberry or ruby undertones . The flowers appear multi-toned—moody, deep coloration perfect for cutting gardens and fall arrangements .
History & Background
Developed by the Jacks of Ferncliff Gardens in British Columbia, Canada, Ferncliff Rusty belongs to the revered “Ferncliff” series known for numerous high-performing dahlias. Though its exact introduction date isn’t always published, it’s widely recognized among growers and featured by many seed suppliers .
Morphology & Appearance
Every bloom is a perfect ball shape, dense and symmetrical. Petal backs often reveal deeper red tones, while petal fronts range from rusty to coral pink, depending on light and stage of bloom . The plant grows to approximately 36–48 inches tall (around 3–4 feet), making it medium height and excellent for garden beds and cut flower stems .
Planting Requirements
- Sunlight: Requires full sun (at least six hours per day) for best bloom production and stem strength .
- Soil: Well-drained soil enriched with compost or organic matter allows tubers to develop strong roots and tuber systems.
- Spacing: Plant tubers 12–18 inches apart, to give sufficient airflow and room for tuber growth .
- Maturity Timing: Typically blooms 80–100 days after planting (seed or tuber), with first blooms around late summer depending on local climate .
- Pinching: Pinch growing tips when plants reach around 12 inches tall to encourage branching and bushier habit .
Bloom Season & Crop Production
Ferncliff Rusty delivers a bumper crop of blooms from first flush until frost. Unlike many dahlias, it seldom suffers from flower drop or shading-off of color; instead, blooms persist with consistent shape and tone . Its relatively early maturity also gives gardeners a long harvesting window.
Harvesting & Vase Life
Ideal harvest time is when blooms are about three-quarters open, avoiding petals that appear papery or dehydrated. Check the back of the bloom head for firmness. Best practice:
- Immediately place cut stems in water with hydrator.
- Or “sear” stems by dipping ends into 160–180 °F (just off boiling) water, then cooling for an hour—this promotes water uptake and extends vase life .
Expect a vase life of about 5 days, making these excellent for cut-flower arrangements and bouquets. The moody tones add depth and drama to flower arrangements.
Garden Uses & Design Appeal
- Perfect in mixed borders, pairing well with lighter summer blooms like dahlias in rose, cream, or gold tones.
- Provides a counterpoint in cottage or cutting gardens, with its jewel-tone blooms and branching habit adapted for arranging.
- Ideal for vase arrangements, where long sturdy stems (up to 4 feet) hold well and showcase the dense ball form .
Comparative Performance & Growers’ Feedback
Many gardeners on platforms like Reddit and Facebook praise Ferncliff Rusty for productivity and color shifts through the season. One commenter called it “magical,” noting that where other varieties stay uniform in shade, Ferncliff Rusty shifts hue subtly over time, adding dynamic interest .
On Reddit’s r/dahlias community, growers say:
“I find the Ferncliff varieties really pump out the blooms.”
A strong endorsement of its floriferous nature .
Tubers Availability & Price Range
Ferncliff Rusty tubers are widely available from multiple North American growers:
- Petals in Bloom Farm lists one tuber around US $18 .
- Triple Wren Farms sells at about US $16, with shipping scheduled around April–May seasonally .
- Micro Flower Farm offers at roughly US $19 per tuber .
Availability may vary and many vendors sell out quickly in tuber season. International availability can be limited; most ship only within the U.S. or Canada .
Step-by-Step Growing Guide
1. Tuber Prep & Start
- In climates with frost, start tubers indoors roughly 4-6 weeks before last frost, in small containers under bright light.
- Hard frost-free zones can direct plant tubers after soil warms.
2. Planting Outdoors
- Drainage is key—avoid soggy beds.
- Place tuber eye side up, covering 4–6 inches deep with soil.
- Water moderately until shoots appear.
3. Pinching & Staking
- When sprouts reach 12 inches, pinch terminal bud to stimulate branching.
- Provide stakes or bamboo supports to hold occasional heavy blooms—especially in windy or rainy weather.
4. Feeding & Maintenance
- Feed with balanced fertilizer, low in nitrogen but richer in potassium/phosphorus, every 3–4 weeks.
- Deadhead spent flowers to encourage continual production.
- Watch for common pests: slugs/snails, state-specific viral diseases—Ferncliff collections are generally virus-managed but vigilance is key.
5. Harvesting
- Harvest at ¾ bloom stage.
- Use searing or hydrator method to maximize vase life.
6. Post-Season Storage
- After frost, cut stalks, lift tubers, clean gently, and cure in a frost-free, ventilated spot.
- Store in slightly moist peat moss or vermiculite over winter at about 4-10 °C (40-50 °F), checking periodically for rot.
Care Notes for Different Climates
- In cool, maritime climates, blooms may lean more raspberry-rust.
- In hotter inland gardens, tones may shift coral-orange.
- Coastal fog or humid summers may prolong bloom period; dryer summers may slightly reduce size but boost intensity.
Ferncliff Rusty adapts well across USDA zones roughly 8–11, with proper mulch in colder zones to overwinter tubers.
Design & Floral Arrangement Tips
- Combine with pale dahlias (e.g., cream or blush tones) to let moody hues stand out.
- Cluster in bud vases (stem-only vessels) for minimalist impact.
- Create autumn or Halloween palettes mixing deep burgundy foliage and soft peach blooms for contrast.
Propagation & Seed Saving
Ferncliff Rusty is typically grown from divisions of tubers, which preserve exact traits. Seed-saving isn’t recommended for true variety retention, as dahlias readily cross-pollinate.
Sustainability & Disease Management
Many growers (e.g., Pedaling Petals) use no-synthetic-fertilizer regimes, compost mulch, and organic pest management to maintain tuber health and virus prevention . Such practices support long-term viability and credit to the Ferncliff lineage.
Troubleshooting Common Issues
- Leggy or sparse stems: likely insufficient sun or overcrowding.
- Poor flowering: may be due to high nitrogen feed or late pinch; adjust accordingly.
- Fading flower color: caused by overwatering or too-rich soil; ensure moderate fertility.
- Pests: Slugs/snails can nibble foliage—use traps or barley straw. Viral symptoms (mottling or streaks) call for removal of affected plants.
