Conservation Status:	Does not currently have a designated conservation status under major international bodies. It is not listed as endangered or threatened.

Cultivation

Planting:	Spacing: Plant chocolate mint about 18 to 24 inches apart to give it room to spread. Method: You can start chocolate mint from seeds, but it's easier and faster to grow from cuttings or by dividing existing plants. Planting rooted cuttings or divisions is the most effective method. Containers: To prevent the plant from becoming invasive, consider planting it in a container, even if you plan to place it in the ground. This confines the roots and makes management easier.
Sun Exposure:	Full sun to partial shade. If you're in a particularly hot climate, some afternoon shade can help protect the plant.
Soil Type:	It prefers moist, well-drained soil. While mint is adaptable to many soil types, it performs best in slightly acidic to neutral soil
Soil pH:	6.0 to 7.0
Water Requirements:	Keep the soil consistently moist but not waterlogged. Mint doesn’t tolerate dry conditions well.
Fertilizer Requirements:	Mint doesn’t require much fertilization. A light application of a balanced, all-purpose fertilizer in spring can be sufficient. Blog post on Natural Fertilizers
Pruning Requirements:	Regular pruning helps keep mint plants bushy and prevents them from getting leggy. You can pinch off the tips of the stems to encourage branching.
Growth Rate:	Fast

Tolerance and Hardiness

Drought Tolerance:	Chocolate mint, like most mint varieties, is not particularly drought-tolerant. Mint thrives in environments where the soil is kept moist but not waterlogged. It's important to water it regularly, especially during hot, dry weather to prevent the soil from drying out.
Frost Tolerance:	It can survive winter temperatures as low as -40°F to -30°F (-40°C to -34°C). In colder climates, mint will die back to the ground in winter but typically returns in the spring. Mulching over the root area can help protect it in winter.
Heat Tolerance:	Mint plants generally prefer cooler conditions but can adapt to warmer climates. They perform well in temperatures ranging from about 55°F to 80°F (13°C to 27°C). They can tolerate higher temperatures, especially if the roots are kept cool and moist.
Wind Tolerance:	Mint plants have relatively flexible stems and leaves, which can usually withstand moderate winds without breaking. However, prolonged exposure to strong winds can cause physical damage, dry out the plant more quickly, and lead to stress.
Salt Tolerance:	Has low salt tolerance. This characteristic means it does not fare well in environments with high salinity, either in the soil or in water irrigation. Salty soils can cause osmotic stress in plants, leading to reduced water uptake and potential ion toxicity. Symptoms of salt stress in mint include stunted growth, leaf burn, and discoloration or drying of leaf edges.
USDA Plant Hardiness Zones:	3a - 10

Flower and Fruit Information

Fruit Type:	None
Harvest Time:	Harvest mint leaves before the plant flowers for the best flavor. You can cut the entire plant down to 1 inch above the ground; it will regrow.
Edible Plant:	Yes
Edible Parts:	Leaves, Flowers, & Young tender stems
Medicinal:	Yes. Mint plants are traditionally used in herbal medicine for their soothing properties. Chocolate mint can help with digestion, relieve symptoms of nausea, and act as a mild sedative.
Flower Color:	The color of chocolate mint flowers ranges from pale lilac to purple, adding a splash of color to the green foliage of the plant.
Flower Shape:	The flowers of chocolate mint are tubular and bilabiate, meaning they have two distinct lobes or "lips." The upper lip is usually slightly arched, while the lower lip is more prominent and divided into three lobes, which can sometimes make the flower appear somewhat mouth-like.
Fragrance:	The fragrance of chocolate mint flowers is a gentle, mildly sweet floral aroma with subtle minty notes, offering a lighter, ethereal quality compared to the more robust scent of the leaves.
Flower Bloom Time:	From mid to late summer. The exact timing can vary depending on the climate and growing conditions, but generally, you can expect the flowers to appear sometime between July and September.
Bloom Duration:	About 4 to 6 weeks, depending on the growing conditions and climate.
Pollination: Self or Other?	Does not typically self-pollinate effectively. Mint is generally sterile, meaning it does not produce viable seeds easily, and as such, it does not rely on self-pollination or even traditional cross-pollination for reproduction. Instead, peppermint primarily reproduces vegetatively through runners or stolons, which are horizontal stems that grow at the soil surface or just below it and root at the nodes.

Wildlife

Pollinators:	Bees, Butterflies, Moths, & Hummingbirds
Problematic Pest:	Mint is susceptible to a few pests like spider mites and aphids, and diseases such as rust and powdery mildew. Regularly inspect your plants and treat with appropriate organic methods if necessary. Blog post on how to control pest
Attracts:	Beneficial insects such as Hoverflies, Ladybugs, Parasitic Wasp

Health and Safety

Toxic:	Answer 1
Poisonous Parts of Plant:	Answer 2
Toxic to Humans:	No
Toxic to Animals:	Mint is also generally safe for dogs, cats, horses and other livestock. In fact, it can sometimes be used in small amounts as a flavor enhancer in feed. Moderation is Key: As with any non-typical feed, it should be introduced gradually and fed in moderation to avoid digestive issues. Mint contains menthol, which in larger amounts might be irritating to some animals, especially if they have a sensitive digestive system.
Plant Diseases to be aware of:	Chocolate mint, like other mint species, can be susceptible to several common plant diseases. Being aware of these potential issues can help you manage your plants better and keep them healthy. Here are some key diseases to watch out for: 1. Powdery Mildew Symptoms: White or gray powdery spots on the leaves and stems. Management: Improve air circulation around the plants, avoid overhead watering, and prune infected areas. Fungicidal sprays may be used as a preventive measure in severe cases. 2. Rust Symptoms: Small orange or brown spots on the undersides of leaves, which can cause leaves to drop prematurely. Management: Remove and destroy infected leaves, and ensure plants are not too densely packed to improve air circulation. Fungicide applications can help control severe infections. 3. Verticillium Wilt Symptoms: Wilted leaves, often starting at the base of the plant, and discoloration of the stem interior. Management: There is no effective treatment once a plant is infected. Remove and destroy affected plants, and plant mint in a different location with disease-free soil. 4. Mint Anthracnose Symptoms: Dark brown to black spots on leaves which may coalesce into larger lesions, leading to leaf fall. Management: Remove affected plant parts and avoid overhead watering to reduce moisture on foliage. Applying fungicides can also be considered in recurrent cases. 5. Root Rot Symptoms: Stunted growth, wilting, and yellowing leaves, often with a decayed root system. Management: Ensure good drainage in the soil, avoid overwatering, and consider using a fungicide if the infection is not too advanced. Prevention Tips: Good Hygiene: Regularly clean up plant debris around the mint to prevent the build-up of fungal spores. Proper Spacing: Space plants adequately to ensure good air circulation, which helps minimize humidity and reduces the risk of fungal infections. Watering Practices: Water at the base of the plant to keep the foliage dry and reduce the likelihood of fungal diseases.
