Foxfibre
Gossypium hirsutum var. Foxfibre
vegetableFoxfibre is a naturally colored cotton variety that produces fiber in shades of brown and green without synthetic dyes. Developed through selective breeding, it offers sustainable textile production while maintaining the agronomic qualities of conventional cotton. This specialty crop appeals to organic farmers and fiber artists seeking naturally pigmented cotton.

Seedling
3-4 weeksCotyledons emerge 7-10 days after planting; first true leaves appear with characteristic cotton leaf shape
Protect from cold (soil should be 60°F+). Keep soil consistently moist but not waterlogged. Thin seedlings to spacing requirements if direct seeding
Vegetative Growth
6-8 weeksPlant develops true leaves, branches form, and height increases. Stem thickens and root system expands. Leaves are large and deeply lobed
Maintain consistent watering and fertility. Monitor for pests. Pinch back terminal growth if excessive branching is desired. Ensure full sun exposure
Flowering
6-10 weeksBuds (squares) form on branch terminals, then open into cream or pale yellow flowers. Flowers typically last one day before dropping
Increase nitrogen slightly to support flower production. Maintain consistent watering—drought stress reduces flowering. Avoid excess nitrogen which delays flowering
Bolling & Fiber Development
6-8 weeksAfter petal drop, the ovary develops into a green boll containing developing seeds and fiber. Bolls enlarge and fiber fills the interior cavity
Reduce nitrogen to redirect energy from foliage to fiber development. Water consistently but allow soil to dry slightly between waterings. Fertilize with phosphorus and potassium-rich formula
Maturity & Harvest
3-6 weeksBolls fully enlarge (walnut-sized), develop their natural brown or green color, and the boll walls split, exposing fluffy fiber
Stop watering 2-3 weeks before harvest to allow bolls to fully mature and open. Harvest as bolls open. Handle fiber carefully to prevent contamination

Common Pests
-
Scout regularly for infested squares; remove and destroy infested bolls; plant trap crops; use pheromone traps; consider organic pyrethrin sprays if population high
-
Hand-pick larvae; use Bt (Bacillus thuringiensis) spray at early instar stage; employ pheromone traps; maintain good field sanitation
-
Remove infested leaves; spray with insecticidal soap or neem oil; introduce beneficial insects like parasitic wasps; reflective mulches deter adults
-
Spray with water to dislodge; use neem oil or sulfur dust; maintain adequate humidity; introduce predatory mites
-
Spray with insecticidal soap; use neem oil; attract ladybugs and lacewings; prune heavily infested areas
Uses
Cotton seed oil (from by-products)
CulinaryCotton seeds pressed from mature bolls yield edible oil rich in polyunsaturated fats. The oil is used in cooking and salad dressings, though less common than soybean or canola oil. [source]
Naturally dyed textiles
HouseholdFoxfibre's inherent brown and green pigmentation allows fiber to be spun and woven into textiles without synthetic dyes, reducing environmental impact. Ideal for organic clothing, bedding, and craft projects. [source]
Hand-spinning and fiber arts
CraftThe unique naturally colored fiber attracts fiber artists, spinners, and weavers seeking sustainable, undyed materials. Small-scale home production provides craft-quality fiber for handmade textiles. [source]
Sustainable textile production
HouseholdFoxfibre reduces or eliminates the need for chemical dyes in the textile industry, lowering water pollution and chemical runoff. It supports organic and sustainable fashion industries. [source]
Pollinator habitat
WildlifeCotton flowers attract bees, butterflies, and other pollinators. Allowing some bolls to mature supports beneficial insect populations in agricultural systems. [source]
Harvest Tips
Harvest bolls by hand when they open naturally and fiber is fluffy and fully exposed, approximately 50-60 days after flowering. Wear gloves—boll edges are sharp. Harvest in dry conditions to prevent fiber moisture absorption. Pick clean bolls first, as fiber darkens if exposed to weather. Process immediately by ginning to separate fiber from seeds
Fun Facts
- 🌱 Foxfibre was developed in the 1980s by Sally Fox through selective breeding to bring back naturally colored cotton varieties that were nearly extinct. The brown and green colors come from pigments in the fiber cell walls (melanin-like compounds).
- 🌱 Natural colored cotton requires no synthetic dyes, making it popular for organic and sustainable fashion, though it currently represents less than 1% of global cotton production.
- 🌱 Cotton bolls split naturally when mature and ready to harvest—a dramatic opening that exposes the fluffy fiber inside, making hand-harvesting easier than many other fiber crops.
