Multiflora Chrysanthemum: Planting, Care, Overwintering, Varieties
View full-size photo

Multiflora chrysanthemum is a bush chrysanthemum that forms a dense ball covered in hundreds of small flowers all by itself. In autumn these “balls” brighten beds, terraces and balconies long after most annuals have faded. Here is what the plant is, which varieties exist, and how to plant, care for, overwinter and propagate multiflora.

What is a multiflora chrysanthemum

Multiflora (Latin for “many-flowered”) is a group of compact hybrid chrysanthemums bred for pots and beds. Its key feature is a genetically built-in shape: the bush branches on its own into a neat ball 30–70 cm across, with no pinching or pruning. The flowers are small, 2–5 cm, single or semi-double, and a single plant can carry several hundred.

Multiflora blooms from late August until the frosts — six to eight weeks on average, longer in a mild autumn. The plant is perennial but tender: in most of Ukraine it is safer to lift it for winter. Multiflora is sold in pots at garden centres and as rooted cuttings in spring.

Multiflora varieties and colours

Most multifloras on sale belong to European-bred series with names starting “Bran”. Varieties within a series share size and bloom time and differ mainly in colour. The most common are:

Branfountainlemon, salmon, purpleone of the most popular series for beds
Branindioyellow-orangebright “autumn” colour
Branroyalyellow, white, pinkshowy balls for pots
Branhillredrich colour, pairs well with white varieties

Besides the variety name, check the bloom time: early multifloras open in late August, late ones in October. Combining two or three varieties gives a bed that flowers right up to the frosts. Choose colours by mood: white and yellow balls lift shady corners, while burgundy and orange set off autumn foliage.

When and how to plant multiflora

The best time to plant multiflora outdoors is late April to May, once frosts are over and the soil has warmed. That gives the bush time to grow into a full ball by autumn. You can buy budded plants in pots in autumn too, but then they are best kept in containers as seasonal decoration.

  • Site: sunny, at least six hours of direct light, sheltered from wind. In shade the ball falls apart and flowers less.
  • Soil: loose, fertile, well drained and neutral. Chrysanthemums cannot stand waterlogging.
  • Spacing: 40–60 cm between plants so the balls don’t touch and get good airflow.
  • Planting: a hole twice the size of the root ball, drainage and a handful of compost at the bottom; don’t bury the stem deeper, and water well after planting.

Care: watering, feeding, shaping

Multiflora is undemanding, but a few simple rules keep the ball dense and full of flowers.

  • Watering. Regular, at the base, as soon as the top 2–3 cm of soil dries. In hot weather two or three times a week, more often in pots. A mulch of bark or straw holds moisture.
  • Feeding. In spring and early summer use a nitrogen fertiliser for leafy growth; once buds appear switch to phosphorus and potassium for flowering. Feed every two to three weeks and stop once the ball is fully open.
  • Shaping. Multiflora needs no pinching — its shape is genetic. You can just remove one or two stray shoots to even out the ball.
  • Spent flowers. Pick them off regularly so the plant stays tidy longer and is less prone to disease.

Overwintering: in the ground or in a cellar

Multiflora survives light frosts, but hard freezes and winter thaws are dangerous for it. That is why in most of Ukraine the plants are lifted after flowering.

  1. After the first frosts, once the bush has finished flowering, cut the stems back to 10–15 cm.
  2. Lift the plant with its root ball and pot it into a container or crate.
  3. Keep it somewhere cool and dark at 0 to +5 °C — a cellar, basement or unheated glazed balcony.
  4. Lightly moisten the soil every three to four weeks so the roots don’t dry out.

In the south, where winters are milder, multiflora is sometimes left in the ground: the stems are cut back, earthed up and covered with mulch or spruce branches. Even there it is safer to keep at least one plant in the cellar as a source of spring cuttings.

Multiflora in pots and on balconies

Multiflora grows beautifully in containers, so it is often bought already in flower for terraces, porches and balconies. Choose a pot 2–3 cm wider than the root ball, with drainage holes. Keep it in the sun, water more often than in the ground and never let it dry out — potting soil can dry within a day or two.

Multiflora does not do well as a houseplant: in a warm flat with dry air it quickly loses its shape. After flowering, move the pot somewhere cool for winter, then in spring plant it out in the garden or refresh the soil and put it back outside.

Propagating multiflora

The most reliable method is cuttings. In March, bring the mother plant that wintered in the cellar into warmth and light. When the new shoots reach 8–10 cm, cut them, strip the lower leaves and root them in damp sand or a light mix under plastic. After two to three weeks they form roots, and in May they go into the ground — by autumn each will be a ball.

Division in spring is simpler: split the mother plant into two to four pieces, each with roots and shoots. Seed is not suitable for multiflora: these are hybrids, and seedlings don’t reproduce the parent’s shape or colour.

Why multiflora flowers poorly or loses its shape

If the ball is loose, bare on one side or short of flowers, the cause is usually one of these:

  • Too little sun. In partial shade the shoots stretch and fewer buds form.
  • Too much nitrogen in summer. The plant grows leaves instead of flowers — switch to phosphorus-potassium feeds after June.
  • Late planting. A cutting planted in July doesn’t have time to form a ball by autumn.
  • Drying out or overwatering. Both extremes weaken the roots and reduce bud numbers.
  • An old plant. Without renewal, multiflora loses its shape in two or three years — refresh it from cuttings every spring.

Pests and diseases

A dense ball gets little airflow, so multiflora’s main enemies are fungal diseases.

  • Powdery mildew — a white coating on leaves, caused by damp and crowding; thinning and fungicides help.
  • Grey mould — brownish-grey spots on flowers in a wet autumn. Remove affected parts and water only at the base.
  • Aphids and spider mites — appear in hot, dry weather; hose them off or use an insecticide.
  • Leaf nematodes — dark wedge-shaped patches between the veins. Infected plants are best destroyed so others aren’t affected.

Prevention is simple: a sunny spot, enough space between plants, and watering in the morning without wetting the flowers.

Multiflora in the garden: what to pair it with

Multiflora balls look great along paths, in borders, in planters by the door and in autumn arrangements. Good companions are ornamental grasses, heucheras, heathers, ornamental cabbage and asters. For a bold accent, plant several balls of one colour as a group or alternate two contrasting varieties.

Chrysanthemums in bouquets

Multiflora is grown mainly for the garden; for bouquets florists use cut spray and single-headed chrysanthemums, which last two to three weeks in a vase. Read how to look after them in chrysanthemums in a vase, and about varieties in types of chrysanthemums. If you want to brighten someone’s day with an autumn bouquet, order chrysanthemums with delivery in Kyiv.

FAQ

Do you need to lift multiflora for winter?

In most of Ukraine, yes. After the frosts, cut the plant back to 10–15 cm, lift it and store it in a cellar at 0 to +5 °C. In the south it can stay in the ground under mulch, but there is still a risk of frost damage.

When should you plant multiflora chrysanthemums?

From late April to May, after the frosts. That way the plant forms a full ball by autumn.

Does multiflora need pinching?

No. Multiflora forms its ball shape on its own — it is a genetic trait of the variety.

What do you do with multiflora after flowering?

Cut the stems back, lift the plant and move it somewhere cool and dark until spring. In March bring it into the warmth to take cuttings.

Can you grow multiflora from seed?

It isn’t worth it: multiflora is a hybrid, and seedlings lose the ball shape and the parent’s colour. Propagate it from cuttings or by division.
