How to Grow Chrysanthemum
'Painted Daisies' from Seed
The tricolour cockade daisy — concentric rings of crimson red, golden yellow and deep purple that look painted by hand, an evolutionary pollinator target refined over millennia, a fast-growing annual with ferny succulent foliage that produces hundreds of cut flowers through summer with cheerful, retro, irresistible energy
The "Painted Daisy" name is almost understated. Each flower is a precisely patterned concentric composition — an outer ring of petals in deep crimson-red, a middle zone in bright golden yellow, and a central disc in rich purple-maroon — a high-contrast, multi-tonal combination that looks more like something designed by a mid-century illustrator than produced by a plant. Individual flowers vary in the exact proportion and intensity of each ring, so a mound of Painted Daisies in full bloom is simultaneously unified in its colour palette and varied enough in expression to be endlessly interesting to look at closely.
The retro, playful quality that makes Painted Daisies so distinctive has a biological purpose: the concentric ring pattern is an evolutionary adaptation that makes the flower highly visible to pollinators from a distance, while the contrasting rings provide precise landing guidance up close. High-contrast circular patterns are among the most effective pollinator attractors in the flower kingdom — the same principle that makes sunflowers so successful. And the result in a garden setting is a plant covered in bees on every sunny day, flowering continuously from midsummer through autumn with minimal attention, producing cheerful cut stems that bring an undeniable charm to summer arrangements.

Understanding the Plant
Ismelia carinata (previously classified as Chrysanthemum carinatum and also known as Glebionis carinata) is a true annual — it germinates, flowers, sets seed, and completes its entire life cycle in one season. This is a completely different plant from the perennial garden chrysanthemums sold in autumn at garden centres — those are typically Dendranthema or Chrysanthemum hybrids that require overwintering and perennial management. Painted Daisies require no such attention: sow in spring, enjoy from midsummer, and compost in autumn.
The Cockade — An Evolutionary Pollinator Strategy
The distinct concentric ring pattern of Ismelia carinata is described as a "cockade" — from the French cocarde, meaning a rosette ornament worn on a hat. The biological explanation for this pattern is more interesting than the aesthetic one: the high-contrast rings of alternating warm and dark colour create an extraordinarily effective visual signal at distance, readable by bees and hoverflies from several metres. The innermost ring (disc) provides the landing zone; the alternating outer rings provide the approach guidance. This is the same principle used by airports in runway lighting — the concentric pattern creates an unambiguous directional signal for approach and landing. The pattern has been selected by pollinator pressure over millions of years and is genuinely one of the most visually striking flower patterns available from any annual seed.
Ferny, Succulent Foliage — Not Just the Flowers
The foliage of Painted Daisies is itself attractive and unusual — finely divided, somewhat succulent in texture (the leaves retain water effectively), a blue-green grey-green that provides a pleasing neutral backdrop to the vivid flowers. This succulent quality gives the plant excellent drought resistance once established, and the ferny texture creates a full, mounding plant habit that is ornamental even when not in flower. In the border, the foliage provides useful texture contrast alongside both fine and bold-leafed neighbours.
Sowing & Establishment
Deadhead Consistently for Maximum Flower Production
Painted Daisies flower in prolific successive waves, but only with consistent deadheading. Remove every spent flower before the seed head develops — ideally snipping the whole stem back to the next emerging bud. With regular deadheading, plants flower continuously from July through October; without it, seed production diverts energy from new flower production and the season shortens significantly. This is the single most impactful management step.
-
Sow indoors February–March at 15–20°C. Sow on the surface or cover very lightly — they prefer light to germinate. Germination takes 7–14 days. Prick out into individual 7cm pots when large enough to handle. Grow on in bright, cool conditions for the most compact, sturdy plants.
-
Alternatively, direct sow outdoors March–May at 3–5mm depth. Scatter onto finely raked soil in full sun. Cover lightly. Germination in 7–14 days. This is the simplest approach — Painted Daisies establish readily from direct sowing and the ferny, succulent seedlings are fairly robust from the outset.
-
Thin or plant to 30cm spacing. Give adequate space — the mounding bushy habit requires room to develop its characteristic full-plant flowering character. Crowded plants produce fewer flowers and more disease-prone stems. 30cm between plants in all directions.
-
Deadhead every spent flower. Begin deadheading as soon as the first flowers fade — remove the whole stem back to the next emerging bud. Continue throughout the season. This single practice is the difference between a three-week display and a four-month display.
Growing On & Care
Full Sun for Best Colour
The intensity of the tricolour ring pattern — the depth of the red, the brightness of the yellow, the richness of the purple disc — is most vivid in full sun. In partial shade, plants grow but the colour rings appear flatter and the contrast between them reduces. Site in the sunniest available position for the most spectacular cockade display.
Drought Tolerant
The succulent, water-storing foliage gives Painted Daisies genuine drought tolerance once established. Water young seedlings regularly in the first month; established plants tolerate dry spells that would stress many other annuals. In very prolonged drought, flowering quality declines — water deeply every week to ten days in extended dry periods.
Cut Flower Value
Painted Daisies are exceptional cut flowers — the stems are long and straight, the flowers face forward cleanly, and the tricolour pattern is as impressive in a vase up-close as it is at distance in the border. Cut in the early morning when the first ring of petals has just opened but the disc is still tight. Condition in cool water for several hours. Vase life is seven to ten days. Strip all lower leaves before placing in water.
Excellent Weather Resistance
Unlike many annuals, Painted Daisies have excellent weather resistance for UK summer conditions — the somewhat succulent petals and the sturdy flower disc structure hold up well through rain and wind without dissolving or falling apart. This makes them one of the most reliably continuous-flowering annuals through the unpredictable British summer.
Colour Variation Within the Mix
Individual plants within a sowing of Painted Daisies show variation — the width of each ring, the intensity of the red, and occasionally the colour combinations differ slightly from plant to plant, producing a living mix of cockade patterns across a planting rather than mechanical uniformity. This variation is a feature rather than a flaw: no two plants are exactly identical.
Self-Seeding
Allow a few late-season flowers to set seed and drop — Painted Daisies self-seed in suitable conditions and the following year's self-seeded plants often flower earlier and more prolifically than fresh spring-sown equivalents. Mark where seed has fallen to avoid disturbing in spring weeding.

Common Problems & Solutions
| Problem | Likely Cause | What to Do |
|---|---|---|
| Flowering season short | Deadheading neglected | Remove every faded flower before seed development begins. Even a two-week lapse in deadheading can trigger the plant into seed mode, dramatically shortening the season. With consistent deadheading from July onwards, the season extends through October. |
| Colour rings faint or washed out | Insufficient sun; overrich soil | Grow in the sunniest available position. In partial shade or on rich, heavily composted soil, the colour contrast reduces. Lean to average soil in full sun produces the most vivid tricolour rings. |
| Plants leggy and falling over | Insufficient sun; overcrowding; very rich soil | Space 30cm apart in full sun. In shade, plants become drawn and leggy. Very rich soil produces lush, tall, floppy growth. Lean, well-drained soil in full sun produces compact, self-supporting mounded plants. |
| Aphids on growing tips | Common in warm spring conditions | Pinch off the most infested growing tips and drop into soapy water. Squeeze colonies between fingers. The sustained presence of bees and hoverflies around Painted Daisies provides biological aphid control — hoverfly larvae eat aphids prolifically. On healthy, established plants, aphid damage is rarely severe. |
