The arithmetic of green
A single peony costs several times more than a stem of eucalyptus, wilts faster, and travels worse. Yet most couples budget for flowers first and treat foliage as the cheap fill between blooms. The logic runs exactly backwards.

Foliage does three things a bloom cannot. It provides mass — the visual bulk that makes a centrepiece read across a room rather than disappearing at eye level. It provides length — trailing stems of smilax, ivy or jasmine vine reach the tablecloth in a way that a tight floral cluster never will. And it provides colour contrast without competing: dark galax leaves or deep-green ruscus make a pale rose appear more itself, not less.
The cold-chain advantage matters too. Most foliage is significantly hardier than cut flowers in transit. Eucalyptus can hold outside refrigeration far longer than, say, a garden rose. That gap in vase life is what separates a centrepiece that looks correct at six in the evening from one that looks correct at noon and tired by the first course.

Photographically, foliage earns its fee twice over. Texture reads in a way that uniform petals often do not — a camera compresses depth, and a tight globe of roses can flatten to a single colour blob, while layered leaves give the image something to resolve. Mixed greens also bounce soft light back toward faces, which is exactly what a photographer wants from the table surroundings.
Seasonality sharpens the case. Foliage is available year-round from domestic growers in a way that premium blooms are not, which means less air freight, steadier pricing and fewer substitutions in the week before the wedding. If the conversation about what 'in season' is really claiming matters to you, green is almost always the honest answer — whatever the month.
The practical rule is to plan the foliage first and treat it as structure, not dressing. Fix the shape and volume with leaves, vines and branches. Then add blooms as punctuation: three or five per arrangement, in a colour that works against the green you have already chosen. The flowers will look more considered, cost less in total, and survive the afternoon.
