"We had a quiet day one day so we thought we would go and drop a bouquet off randomly on the street somewhere.
"We have such nice customers come in that we thought it would be a nice thing to do. I lent the bouquet on a fence post and put a note on them."
The gesture gained quite a lot of interest on social media.
"We found out who got it and they sent us a lovely message."
Anna said the shop got a lot out of it too.
"It's like getting a big hug.
"People say such lovely things to you and you've done such a simple thing."
Anna looked forward to carrying on the initiative.
"We will keep doing it randomly when we get the chance."
And she hoped it would spur people to "pass the karma along".
The Wilderness has been in Seaview Rd for about eight months.
"We use local flowers where possible and we've got a local guy, Mike King from Finders Eaters, who forages for us which gives us a bit of a point difference.
"He gets a lot of our foliage."
Anna has been in floristry for about 15 years, after studying at Whitireia Polytechnic, Porirua.
One of her jobs used to be operating a flower caravan in Waikanae Beach.
