Fringed Dahlia ‘Tsuki Yori’ (Dahlia ‘Tsuki-yori-no-shisha’) produces large, fully double flowers up to 20 cm (8 in) in diameter. Their long, narrow florets, white to creamy white with a slightly greenish tint near the base, end in deep divisions that create a feathery, dishevelled texture. No central disk is visible. The medium green foliage accompanies an upright clump approximately 90 cm (35 in) tall and 50 cm (20 in) wide. Van Noort’s No. 1 tuber blooms from mid-summer until the first frost. Its sculptural silhouette brightens up beds, large containers, and cutting gardens, where the fringed flowerheads become remarkable focal points.
Plant the tuber after the last frost, when the soil has warmed up, in a sheltered location with full sun. Lay it 10 cm (4 in) deep, bud side up, in fertile, humus-rich, fresh, and freely draining soil. Leave about 50 cm (20 in) around the crown and immediately install a sturdy stake. Water sparingly before emergence, then deeply at the base when the surface is dry. Pinch the shoot back to 20–30 cm (8–12 in) to encourage multiple stems. Incorporate mature compost before planting and fertilize moderately, with more potassium once buds appear. Avoid excess nitrogen, stagnant water, and watering dense flowers.
Install Tsuki Yori near a path to observe the long fringed tips and their subtle creamy reflection. Combine it with midnight blue salvias, chocolate cosmos, pink gaura, green zinnias, and purple grasses. Harvest almost open stems early in the morning and regularly remove spent flowers to prolong production. The very double flowerheads offer little access to pollinators; therefore, add nearby single flowers. Monitor for slugs, aphids, earwigs, and spider mites, and maintain good air circulation. In Quebec, after the first frost, lift the tuber, let its surface dry, label it, and store it in a cool, dry, dark, and frost-free place until spring.

Growing method
After the last frost, loosen a sunny area to a depth of 12 inches (30 cm) and incorporate mature compost. Place the tuber horizontally 8 inches (20 cm) deep, bud side up, then leave 16 inches (40 cm) around the crown. Backfill without compacting and water only if the soil becomes dry before emergence. Pinch the shoot 8 to 12 inches (20 to 30 cm) above a pair of leaves. Immediately install a sturdy stake. When growth accelerates, water deeply at the base and fertilize sparingly, favoring potassium for the buds. Tie the stems with soft ties, harvest flowers when nearly open, and remove spent flower heads. After the frost, cut the stems, lift the tuber, let its surface dry, and store it in a cool, dry, frost-free place. The deep purplish-white contrast with velvety texture remains sharper when the plant receives at least six hours of direct sun and regular feeding without excess nitrogen. A stake installed early supports the 8-inch (20 cm) flower heads after rain without compressing the stems or damaging active roots. Remove faded flowers before seed formation so that the clump directs its energy towards new buds until the first frost.

Watering
Water regularly to keep the soil evenly moist without overwatering. Reduce watering before autumn tuber lifting. Water sparingly before emergence, then deeply at the base when the surface dries. Avoid excess nitrogen, standing water, and watering dense flowers. In Quebec, after the first frost, lift the tuber, let its surface dry, label it, and store it in the dark, cool, dry, and frost-free until spring.
Soil type
Opt for humus-rich soil that retains moisture while allowing excess water to drain. Check drainage after rain: water should be able to leave the root zone. Work the soil when it is crumbly to avoid compaction. Adapt amendments to its actual texture. In containers, use appropriate potting soil and a pot with drainage holes. Keep these openings clear and avoid any water accumulation in the saucer.
Fertilization
Incorporate mature compost prior to planting. At the start, use a balanced formula low to moderate in nitrogen; then, as buds appear, prioritize potassium. Follow dosage instructions and water afterward. Too much nitrogen results in tender stems and fewer flowers. The deep purplish-white contrast with velvety texture remains sharper when the plant receives at least six hours of direct sunlight and regular feeding without excessive nitrogen.
Seasonal care
In spring, inspect the tuber, remove only rotten tissue, and plant after the last frost in warmed soil. Install support immediately. Until emergence, avoid repeated watering. In early summer, pinch the shoot at 20 or 30 cm (8 to 12 in), tie new stems, and keep the soil moist without saturation. As soon as buds appear, fertilize moderately with more potassium. In summer, water deeply at the base during dry periods, harvest nearly open flowers, and continuously remove spent blooms. Monitor for slugs, aphids, earwigs, spider mites, and gray mold. After the first frost, cut back stems, gently lift the tuber, let its surface dry, label it Tsuki Yori, and store it in a dark, cool, dry, and frost-free place. Check it monthly during winter. The deep purplish-white contrast with a velvety texture remains sharper when the plant receives at least six hours of direct sun and regular feeding without excessive nitrogen. A stake installed early supports the 20 cm (8 in) flower heads after rain without compressing the stems or damaging active roots. Remove faded flowers before seed formation so the clump directs its energy towards new buds until the first frost. Always water slowly at the base, then let the top layer breathe to maintain a balance between coolness, oxygen, and drainage. The deep purplish-white shades with a velvety texture pair particularly well with blue, white, and light perennial grasses.
Container growing
A garden,within reach.
Recommended pot size
Capacity 40-50 L, deep and very stable
Container growing requires planning for the necessary root volume and the final height of the plant. Choose a stable pot with drainage holes and a substrate suitable for planting. Leave enough space to respect the recommended depth and spacing, rather than cramming plants together to fill the pot immediately. Place the container in the indicated exposure and regularly check the moisture level, especially in hot or windy weather. A pot is more exposed to temperature variations than a plant in the ground. Therefore, plan ahead for a wintering location compatible with the plant's needs and your region's climate. Plant in spring when all risk of frost has passed and the soil is sufficiently warmed. Choose a sunny location, sheltered from strong winds, in fertile and well-drained soil. Arrange the tuberous roots with their crown and buds facing upwards, without breaking the fragile attachments. Install a stake at planting time if support will be needed, to avoid damaging the roots later. Water sparingly at the start, then adjust watering to the foliage growth. Constantly waterlogged soil around the tubers should be avoided, especially before the first shoots appear. Plan to bring the storage organs indoors to protect them from frost during the Quebec winter.

Garden associations
In goodcompany.
Companion plants
To accompany Dahlia 'Tsuki Yori', you could consider cosmos, zinnias, or ornamental salvias. Choose companion varieties based on their height, flowering period, and the colors you wish to combine. Most importantly, ensure their sun exposure and water needs are suitable for the same location. Leave enough space so that leaves don't obscure young shoots and to easily access each plant during maintenance. These associations are for creating the garden's aesthetic; they do not guarantee protection against pests or diseases. Adjust the layout after observing one growing season.
Frequently asked questions
Your questions,answered.
When to plant the Tsuki Yori dahlia?
Plant the tuber after the last frost, when the soil has warmed up and is no longer saturated. Plant it 20 cm (8 in) deep, bud facing up, in fertile, humus-rich, well-drained soil. Leave 40 cm (16 in) around the crown and install a support immediately. In cold regions, start it in a pot four to six weeks earlier, then gradually acclimate the shoot before planting it out. Water very little before emergence to avoid rot, then increase watering when roots and stems are active. Full sun develops strong stems and intensifies the purple-red and black contrast.
What color are Tsuki Yori's flowers?
Tsuki Yori can produce flower heads up to 20 cm (8 in) across when the plant receives full sun, fertile soil, deep watering, and balanced nutrition. To concentrate energy into one bloom, keep the terminal bud on a stem and carefully remove the side buds. Install a sturdy stake before growth and loosely tie the stem to it. This technique reduces the total number of flowers; therefore, allow several other stems to branch out normally if you also want to harvest bouquets throughout the season. Protect large flower heads from strong wind and prolonged rain. Check each tie after summer thunderstorms.
How to support and help Tsuki Yori flourish?
Install a sturdy stake at planting to avoid damaging the roots later. Tie the stems with soft ties as they grow. Pinch back young shoots to 20 to 30 cm (8 to 12 in) to encourage more branching. Water deeply at the base when the surface dries, then allow excess water to drain. Incorporate mature compost initially and then use a moderate fertilizer, richer in potassium, once buds form. Avoid excess nitrogen, which produces tender stems and a lot of foliage. Regularly remove faded flowers so that energy is directed to subsequent buds until frost.
Can Tsuki Yori grow in a large pot?
Yes, choose a stable container of 40 to 50 L, deep, well-drained, and filled with rich but aerated potting soil. Plant a single tuber 20 cm (8 in) deep and insert the support before the roots develop. Place the pot in full sun, protected from gusts. Water sparingly before emergence, then abundantly when the top layer dries, without leaving water in the saucer. Provide moderate liquid fertilization, richer in potassium as soon as buds appear. Turn the container every week, pinch off young shoots, and remove faded flowers to maintain a balanced shape and generous blooming.
How to winterize Tsuki Yori in Quebec?
After the first frost blackens the foliage, cut back the stems, leaving a short section. Lift the tuber with a fork, working far enough away to avoid damaging it. Gently remove excess soil, allow the surface to dry in a ventilated area, and clearly label it Tsuki Yori. Store it in a dark, cool, dry, and frost-free place, in a lightly insulating material that limits desiccation without retaining water. Inspect it monthly. Remove only parts showing active rot and increase ventilation if condensation appears. Wait until after the last spring frost and for the soil to warm up before replanting.
Wildlife and pets
