Flowers

Florists (and many other vendors) will often push for things that either make their job easier or add more money to their pockets. Are these "pops of color" adding to the cost of your bouquets? Are they flowers he often works with so he feels more comfortable working with them? Are they flowers he is already ordering for another job and will be able to save himself money using them in your bouquets as well? These are the things I ask myself when a vendor is pushing for something that clearly doesn't follow my plans for my wedding. Purple is not part of your wedding. Why is he being pushy? It's not his wedding.

If your deposit was too big for you to walk away from, go have a meeting with him without your MIL so you can be blunt. "These are my colors. Purple is not part of my wedding so I don't want it in my bouquets." "This is the design I want for my wedding. I understand you have a different vision but it's my wedding and I like the idea of doing something a little unique."

Copper seems plenty colorful to me. Don't let him bully you. It's your wedding after all. Pussy willow is gray and really fun! Great texture. You can also get a couple of copper roses which could be pretty too.

Ok it's probably because blue, grey and copper aren't colors that flowers come in...

This is the flowers I had showed the florist. I wanted to incorporate more greys and blues with copper wiring around the bouquet. He wants to add a lavender flowers but I just don’t think it would look good together.

Hey!
I disagree with just trying to add money to their pockets. I owned a Florist for many years.

I actually agree with him, a dark purple will make your color palette pop. It will make the other colors stand out more.

Floral designers are in that particular business for a reason. They see color and depth of color differently than a lay person does.

We are artists and only want to use our experience to enhance your flowers. The colors in your palette are flat colors . dark purple will add some pizzazz.

I don't think hes a bully. He's giving you the benefit of his professional knowledge. I think you may be surprised at how beautiful the colors will play off each other, if you just trust him

I promise! It will be spectacular!
Blue, gray and purples are all from the same color family.
I totally agree with his opinion.

Tell me the types of flowers he is using. If, you don't mind. I'll give you my 100 percent truthful opinion, as a floral designer.

I think it’s cool for him to make suggestions and all, but if it’s not something that you want/don’t really like you should definitely put your foot down. It’s your wedding/your money/your choice. Alycia’s wording is perfect for what you could say to him, it’s nice and firm and should put him in his place.

Hey!
Just looked at your example photo....
I promise dark purple will be fantastic with these colors!
It will take it up to the next level 100% agree with him

I would do a darker purple with the lavender, not just the lavender, if I was designing for you. Maybe add some dark blue delphinium as well. It also comes in light blue...but I think dark blue will be gorgeous.
Just my two cents.

The dark purple flower add dimension, he's likely trying to prevent your bouquets from being too bland. Anemone tends to have purple hues as does a lot of the berries in the example photo you used, he's probably trying to draw out the colors.
If you really hate the purple then tell him you appreciate his opinion but you'd rather try something else because purple won't be anywhere else in the wedding. He might have other ideas and purple is just the most straight forward option.
Also the bouquet you showed us is more black and white than navy and copper you might want to opt for some lighter colored flowers or do all white because blue, copper, and grey are hard to find in nature.

Its your day and your paying him so demand what you want, but say it nicely lol

He might just be offering suggestions. Tell him thanks but you like what you picked out

The color scheme is beautiful however the pop of color would accentuate your theme. Trust the florist, they are professionals at what they do 😊
