Fall color for a spring wedding?

So we are getting married in May of 2019. I love burgundy (I am obbessed with the color). I still want to use it as my one of my colors. The bridesmaids with wear burgundy dresses. When people ask what my colors are and I show them the picture below they mention that burgundy isn't really a spring color. I just always change the subject. I know they aren't trying to be rude of anything just stating a fact I already know. I mean I know it's not but I figure since it's our wedding and FH and I like the color scheme I came up with it really shouldn't matter if it's not "a spring" color right? I talked with a florist today just to ask questions about certain flowers and when I told her my colors she said "Even if you don't do burgundy flowers you need to change that color cause it's a fall color not a spring color. I don't understand why you going brides think burgundy and navy are colors you should be using for your spring weddings." I kinda thought it was rude for a women who doesn't know me and is possibly the person we do business with shouldn't make comments tell me what I should or shouldn't do. She was also super short with me. One or two word answers. I was just hoping to talk to someone about flowers since I have no clue what I am doing and I figured it wouldn't hurt to ask questions. The shop wasn't busy and I did ask if she had time to talk wedding flowers. I didn't want to bother her if she was busy. I am a very polite person and so I didn't react when she was what I thought was acting rude. I just listened and left when she had "answered" my questions. As I walked out she said again how I NEED to change that color. Am I crazy for feeling she was being rude? I think I could be wrong and she wasn't rude. I could have taken it out of context. Is it really that big of a deal I am using a fall color in the spring? We are getting married in a rustic Apple orchard. I attached the color scheme I came up with.
