Citrange: The Cold-Hardy Citrus Hybrid That’s Shaking Up Northern Gardens
If you’ve ever dreamed of growing citrus in cooler climates but thought it was impossible, meet the citrange (×Citroncirus webberi) – a fascinating hybrid that’s pushing the boundaries of where citrus can thrive. This unique tree combines the best traits of sweet oranges and hardy trifoliate oranges, creating something entirely new for adventurous gardeners.
What Exactly Is a Citrange?
The citrange isn’t your typical backyard tree. This perennial woody plant is actually a human-made hybrid, created by crossing a sweet orange (Citrus sinensis) with a trifoliate orange (Poncirus trifoliata). The result? A tree that can handle much colder temperatures than traditional citrus while still producing interesting fruits and gorgeous blooms.
As a tree species, citranges typically grow 13-16 feet tall with a single trunk, though environmental conditions can sometimes result in shorter, multi-stemmed forms. Think of it as citrus’s tough cousin – not quite as sweet, but definitely more resilient.
Why Consider Growing Citrange?
Here’s where things get interesting. While citrange isn’t native to North America (it’s a laboratory creation, after all), it offers some compelling benefits for gardeners in challenging climates:
- Cold hardiness: Hardy in USDA zones 7-10, significantly more cold-tolerant than regular citrus
- Fragrant flowers: Produces beautiful white, fragrant blooms that attract bees and other pollinators
- Unique fruits: Small orange fruits that, while quite tart, can be used for marmalades and cooking
- Glossy foliage: Attractive evergreen leaves provide year-round interest
- Conversation starter: A rare and unusual addition to any garden
The Native Alternative Consideration
Since citrange isn’t native, you might want to consider native alternatives that provide similar benefits. Native flowering trees like serviceberry (Amelanchier species) or native citrus relatives in warmer zones could offer comparable pollinator benefits while supporting local ecosystems.
Growing Conditions and Care
Ready to give citrange a try? Here’s what this hybrid needs to thrive:
Sunlight: Full sun is essential – at least 6-8 hours of direct sunlight daily
Soil: Well-draining soil is crucial. Citrange absolutely hates wet feet, so ensure good drainage to prevent root rot
Water: Moderate watering – keep soil consistently moist but never waterlogged
Climate: Thrives in USDA hardiness zones 7-10, but may need winter protection in zone 7
Planting and Care Tips
- Timing: Plant in spring after the last frost date
- Location: Choose a spot protected from strong winds
- Spacing: Allow plenty of room for mature size (13-16 feet)
- Winter care: In zone 7, consider wrapping or moving container plants indoors
- Pruning: Prune lightly in late winter to maintain shape and remove dead wood
- Fertilizing: Use citrus-specific fertilizer during growing season
Is Citrange Right for Your Garden?
Citrange works best in Mediterranean-style gardens, citrus collections, or as a unique specimen plant. It’s perfect for gardeners who want to experiment with unusual plants or those in cooler climates who’ve always wanted to try growing citrus.
However, keep in mind that this isn’t a tree for small spaces, and the fruits, while interesting, aren’t as sweet as commercial oranges. If you’re looking for a productive food tree, you might be better served by more traditional options.
The citrange represents an interesting intersection of horticulture and innovation – a plant that exists purely because humans wanted to push the boundaries of what’s possible. Whether that makes it right for your garden depends on your appetite for horticultural adventure and your local growing conditions.
