Seasonal Flowers: Month by Month Through the Year

Why seasonality matters at all. Cut flowers are harvested in abundance when nature delivers them — supply is plentiful, wholesale is cheap, and quality is at its peak. Against the season, the same flower has to come from a heated greenhouse or be flown in from the Southern Hemisphere: more expensive, often with longer transport and shorter vase life because the stems have already been travelling for days. Buying in season therefore almost always means: fresher in the vase, longer enjoyment, less money. If you want to think this through, the matching buying guide is under “Buying seasonal flowers”.

January to February — buds in the depth of winter. The year opens with bulb flowers: tulips arrive from January in every colour, ranunculus and anemones follow with their dense, almost unreal layered blooms. Hyacinths and narcissi bring the first scent into the home, and amaryllis carries its Christmas peak into January. These early heralds of spring are cheap because they are grown by the million under glass — ideal for bright, fresh bouquets in the darkest weeks of the year.

March to May — the great spring wave. Now the widest window of the year opens. In March and April, tulips, narcissi, hyacinths, anemones and ranunculus stand in full glory and at rock-bottom prices. May is the secret highlight: peonies with their extremely short season, plus lilac, lily of the valley, iris, early roses and sweet peas. If you love peonies, grab them in May — outside May and June they are barely available in Europe, and imports cost many times more. It is also the season around Mother's Day, when seasonal bouquets are especially convincing.

June to August — summer in full flood. In high summer you can truly draw from the full range of cut flowers. Sunflowers begin their long season from July, gladioli define July and August, and summer classics like zinnias, snapdragons, marguerites, scabiosa, cornflowers, lisianthus and gypsophila fill the buckets. August is the hydrangea month above all. It is the time for lavish, meadow-like bouquets — and the ideal season to buy regionally and in the spirit of slow flowers. What to watch for in summer is covered in the guide “Flowers in summer”.

September to December — abundance, then transition. Late summer brings dahlias in all their shapes, from pompom to dinner-plate size, alongside asters and the first chrysanthemums. Dahlias last into October, then chrysanthemums clearly take over — they are the autumn flower par excellence and carry the season into November. November also marks the return of the amaryllis season, which celebrates its peak at Christmas. Combined with eucalyptus, ruscus and wintry greenery, this creates warm, dense bouquets that carry the cold season.

Year-round companions — and why even they have a best time. Roses, carnations, gerberas, lilies, freesias, lisianthus, chrysanthemums, orchids and calla are available all year because they are grown under controlled greenhouse conditions. But even here there are quality windows: outdoor roses in summer are more fragrant and sturdier than their winter counterparts, and freesias shine in spring. These steady performers are the reliable base, while the true seasonal stars give a bouquet its character. A good rule of thumb: one or two year-round anchors, the rest from whatever is in peak season.

How to use the calendar day to day. First: buy what is sitting lavishly in the buckets right now — that is always the freshest and cheapest choice. Second: actively plan for short seasons. Peonies and lilac are there in May and gone by July; lily of the valley is available for only a few weeks. Third: mind the durability — seasonal, ripe-harvested stems last longer with good care because they did not sit in a cargo hold for days. At Fleura, the daily supply at the Veiling Rhein-Maas auction decides what goes into the bouquets; whatever is in season ends up in the bucket first. The right care after purchase is then the second lever for long vase life.
