The first quote I got for my wedding bouquet was $340. Eleven kinds of flowers, two colors of ribbon, a custom monogram pin. The florist was lovely and said yes to everything.

I went home, looked at the quote, and cried for the wrong reason. Then I called my mom's old neighbor, who'd done flowers for two cousins' weddings, and asked if she'd do mine. She said sure. I sent her four photos from Pinterest. The bouquet she made cost $90, used four flowers, and it's the only thing in our wedding photos people have ever stopped to ask about.

The four flowers

Cream garden roses (six stems, $32). Dusty pink ranunculus (eight stems, $24). A small handful of waxflower (one bunch, $8). A few sprigs of eucalyptus from the same bunch she'd used for the centerpieces (free). Tied with a length of off-white silk ribbon she had in a drawer.

That's the whole bouquet. It's not minimal. It's just specific. There's a real difference and I didn't know it until she explained it on the phone.

The trick was four flowers I actually liked, instead of eleven I sort of liked. The math works the same way for everything in a wedding.

Why the first quote was so high

Florists charge by the stem and by the variety. Eleven kinds means eleven trips to the wholesaler, eleven different vases of conditioning water, eleven labels on the order form. They're not trying to rip you off. The math is real. But the math is also why the bouquet starts to look busy — they have to use what they bought.

When you ask for fewer kinds, you're asking them to do harder work. Pick well, gather loose, let the flowers sit the way they want to sit. The bouquet ends up looking like someone walked out to a garden and grabbed it. That's the whole effect. It costs less because it uses less. It looks more expensive because it knows what it is.

What I'd tell anyone planning

Save five photos. Not fifty. Five bouquets you'd actually carry. Look at them side by side. Count the kinds of flowers in each. Almost every one will have four or fewer.

Send the five to your florist. Don't describe what you want. Show them. Say: this mood, this color range, four kinds, one ribbon. Ask what's in season the week of your wedding. Take their answer.

Skip the ribbon trail. One length of silk, six inches past the stems. No bows. The ribbons that go down past the dress make every photo look like it's from 2014.

Use the same flowers for the table. The eucalyptus sprigs in my bouquet were leftover from a bunch the florist had used for the long table. Free, but more importantly, the photos have a coherence that I would not have gotten if the bouquet and the centerpieces had nothing in common.

The quote you don't get

Three years out, the wedding I keep coming back to is my college roommate's. Her mother grew dahlias. The bouquet was nine dahlias from the backyard, tied with a piece of twine. It cost zero dollars and I have stared at the photo of it more times than I have stared at any bouquet that ran $400.

I'm not telling you to grow your own dahlias. I'm telling you the math is upside down on flowers. The expensive ones often look it. The cheap ones, if they're chosen well, almost always don't.
