The plant known as Chrysanthemum yezoense, often simply referred to as the Hardy Chrysanthemum, presents a visual delight with its vibrant display of flowers. These blooms typically showcase a rich variety of colors that may include shades such as white, pink, red, or yellow. The center of the flowers, or the eye, often contrasts in color, providing a striking focal point amidst the petals. The petals themselves are radiant and can be arranged in several patterns; they may be long and slender or more rounded, and they can be layered in a lush, overlapping manner or set more sparsely around the central disc. The foliage of the Hardy Chrysanthemum is equally attractive and contributes to the overall appearance of the plant. The leaves are typically a deep, rich green, and their shape can vary. Some may be lobed or deeply cut, while others are more elongated and slender with smooth or serrated edges, imbuing the plant with a full, bushy appearance.

ToxicityTo humans
Chrysanthemum yezoense, commonly known as Yezo-giku, is not widely recognized for being particularly toxic to humans. There are no well-documented cases of poisoning in humans from ingesting this specific species. However, other species within the Chrysanthemum genus do contain pyrethrins and other compounds that can cause dermatitis or allergic reactions in sensitive individuals. If ingested in large quantities, these compounds may lead to symptoms such as gastrointestinal upset including nausea, vomiting, diarrhea, and in severe cases, could potentially result in neurological symptoms. It is always recommended to exercise caution and avoid ingesting plants not known to be safe or intended for human consumption.
To pets
Yezo-giku is considered potentially toxic to pets, especially cats and dogs, due to the presence of pyrethrins and sesquiterpene lactones, which are common in many Chrysanthemum species. Ingesting parts of this plant can lead to symptoms such as vomiting, diarrhea, hypersalivation, dermatitis, and loss of coordination in pets. In severe cases, it might cause tremors or seizures, indicating a more serious toxic reaction. If you suspect that your pet has ingested any part of the Yezo-giku plant, it is important to contact a veterinarian immediately.

WaterThe Chrysanthemum yezoense, commonly known as the Hardy Chrysanthemum, requires consistent moisture and should be watered thoroughly whenever the top inch of soil feels dry to the touch. An average watering schedule could be once every week, but this depends on climate and weather conditions; more often in hot, dry weather and less in cool, damp weather. When watering, aim to soak the soil around the roots with about one gallon of water, avoiding wetting the foliage to reduce the risk of disease.
LightHardy Chrysanthemums thrive in full sun to partial shade. They prefer a spot that receives at least 6 hours of direct sunlight a day but can tolerate some light afternoon shade, which can protect them during the hottest part of the day. Ensuring adequate light helps Hardy Chrysanthemums produce the most abundant and vibrant blooms.
TemperatureHardy Chrysanthemums are tough plants that can survive in a wide range of temperatures, from as low as 30°F to as high as 90°F. However, the ideal growing temperature for these plants is between 60°F and 75°F. Extreme temperatures outside the aforementioned range may stress the plants and affect flowering.
PruningHardy Chrysanthemums benefit from regular pruning to encourage bushy growth and more blooms. Pinch back the growing tips when the plants are about 6 inches tall and continue to do so until midsummer. After blooming, cut back the stems to prevent seed formation and to tidy the plant, which also helps with disease prevention. The best time for heavy pruning is early spring or right after the flowers have faded.
CleaningAs needed
SoilThe best soil mix for the common Chrysanthemum, also known as Hardy Mum, should be well-draining and fertile, with a peat moss or compost base. Incorporate perlite or vermiculite to improve drainage. The ideal pH for this soil should be mildly acidic to neutral, ranging from 6.0 to 7.0.
RepottingHardy Mums should be repotted every one to two years to refresh the soil and accommodate root growth. It is best done in the late winter or early spring before new growth begins.
Humidity & MistingHardy Mums thrive in moderate humidity levels. They do not require any special humidity considerations and can adapt to normal outdoor humidity conditions where most common plants grow well.
Suitable locationsIndoor
Place in bright indirect light and well-draining soil.
Outdoor
Plant in sun to partial shade with good airflow.

Life cycleThe life cycle of Chrysanthemum yezoense, commonly known as Yezo-giku, begins with seed germination, which occurs in spring when soil temperatures rise and moisture levels are adequate. Following germination, the seedlings grow into juvenile plants, developing a rosette of leaves near the soil surface. As the plants mature during the growing season, they form characteristic lobed leaves and branched stems. By late summer or early autumn, Yezo-giku enters the flowering stage, where it produces vibrant flowers, often in shades of yellow, which are critical for attracting pollinators. After pollination, the flowers set seeds, which are then dispersed by wind or wildlife to propagate the next generation. As winter approaches, the plant enters dormancy to survive adverse conditions, resuming growth the following spring.
PropogationPropogation time
Spring to Summer
The most popular method for propagating Chrysanthemum yezoense, commonly known as Yezo daisy, is through cuttings. This is typically done in early spring or summer when the plant is actively growing. To propagate by cuttings, a healthy stem tip about 4 to 6 inches (approximately 10 to 15 cm) long is cut just below a leaf node. The lower leaves are removed, and the cut end is dipped in rooting hormone before being placed in a well-draining soil mix. The cutting is then kept moist and in a warm place with indirect sunlight until roots have developed, which usually takes a few weeks. Once the roots have formed, the new Yezo daisy plant can be transplanted into the garden or a desired container.
