Growth Rate
|
- Speed: Moderate growth rate, with fronds emerging in spring and reaching full size by summer.
- Mature Growth: Reaches 24-30 inches in height and 18-24 inches in width, forming a lush, arching mound.

Wildlife Attraction
|
- Attracts: Provides shelter for small wildlife, but does not attract pollinators or provide a food source for insects.
- Wildlife Resistant: Deer and rabbits tend to avoid this fern, making it a great choice for wildlife-prone areas.
|
Seasonality
|
- Foliage Season: Spring through fall; dies back in winter.
- Flowering Season: Ferns do not produce flowers; they reproduce through spores.
- Hardiness Zones: USDA Zones 5-8
|
Ideal For
|
- Woodland gardens
- Shaded borders
- Ground cover
- Containers
- Fern gardens
|
Leaf Description
|
- Color: Vibrant golden-yellow fronds emerge in spring, gradually maturing to deep green as summer progresses.
- Form: Large, arching fronds with finely divided, feathery leaflets. The foliage creates a lush, exotic texture in the garden.
- Fall/Winter Interest: The foliage turns a dark bronze or brown in the fall before dying back for the winter. The plant re-emerges with fresh golden fronds the following spring.
|
Flower Description
|
Dryopteris 'Jurassic Gold' is a fern, which means: - It does not produce flowers, petals, or reproductive floral organs.
- Instead of flowering, ferns reproduce via spores, making them part of a non-flowering plant group called pteridophytes.
|
Planting Instructions
|
- Planting Time: Best planted in spring or fall when the soil is moist and the temperatures are cool.
- Soil Requirements: Prefers well-drained, humus-rich soil. Tolerates a wide range of soil types as long as it is consistently moist. Slightly acidic to neutral soil (pH 5.5-7.0) is ideal.
- Planting Depth: Plant at the same depth as in its nursery pot, with the crown at or just above soil level.
- Spacing: Space plants 18-24 inches apart to allow for mature spread and airflow.
|
Pruning & Maintenance
|
- Timing: Prune in late fall or early spring before new growth begins.
- Method: Remove old, damaged, or dead fronds at the base of the plant to encourage new growth and maintain the plant’s tidy appearance.
|
Water Needs
|
- Watering Frequency: Water regularly, especially during dry periods. Keep the soil consistently moist but not waterlogged.
- Soil Moisture: Prefers consistently moist, well-drained soil. Ensure good drainage to prevent root rot.
|
Light Needs
|
Thrives in partial to full shade. Can tolerate dappled sunlight but prefers shaded areas for optimal growth and vibrant color. Full sun may scorch the fronds. |
Harvesting
|
1. Spore Harvesting (for Propagation)- Timing: Late summer to early fall, when sori (spore clusters) mature.
- Location: Check the underside of mature fronds for rows of brownish dots (sori).
- Steps:
- Cut a fertile frond with mature sori.
- Place it spore-side down on a sheet of white paper.
- Cover with a book or tray to prevent air movement.
- After 24–48 hours, a fine brown dust (spores) will drop onto the paper.
- Store spores in a paper envelope in a cool, dry place until you're ready to sow.
2. Frond Harvesting (for Ornamental Use)- Use: Fresh fronds may be used in floral arrangements or foliage displays.
- Note: Fronds do not dry well and typically wilt quickly, so they are best used fresh and short-term.
Best Time to Cut: Early summer when fronds are fully unfurled but still firm. |
Fertilizing
|
- Fertilization Time: Fertilize in early spring as new fronds begin to emerge.
- Fertilizer Type: Use a balanced, slow-release fertilizer or organic compost to promote healthy growth. Avoid over-fertilizing to prevent leggy growth.
|
Additional Care Tips
|
- Mulching: Apply a 2-3 inch layer of mulch around the base to retain soil moisture and suppress weeds. Keep mulch away from the crown to prevent rot.
- Drought Tolerance: While Jurassic Gold prefers consistently moist soil, it can tolerate short periods of dryness once established, especially in shaded areas.
- Pests and Diseases: Generally pest and disease-free. It may occasionally be affected by slugs or snails, but good air circulation and proper soil drainage help prevent any issues.
|
Pollination
|
Ferns reproduce via spores, which are produced on the undersides of mature fronds in late summer to early fall. They do not require pollination. |
