She had just got off the phone from the courier company who said they could get the flowers to her by the following evening.
However, she needed them about eight hours earlier than that, even though the wedding was not until two days later - she had to set it up a day early and then get back to Cromwell to pack her bags as she had a plane to catch.
Ms Wilson-Thiel (54) has not been in the floristry game for many years but was invited to take part in a prestigious workshop at the Institute of Floristry in Minneapolis - a floristry school that she described as one of the top in the United States.
Though it means closing her shop for a month, "it was too good of an opportunity not to go".
"It's a fantastic opportunity.
"It's great because I can come back and hopefully get a group together here ... in New Zealand, florists tend to isolate themselves."
She was chosen because Institute of Floristry was the school at which she learned her craft but even though they train between 400 and 500 people a year, only five were selected to take part in this workshop and she was the only one from outside the United States.
Each of the five floral designers will be paired with a master designer and each couple will be tasked with designing table settings and bouquets with the aim of establishing design trends, colours and styles for the coming year.
There is a personal perk to her trip - she will get to see her husband.
Darrel Thiel, a retired American soldier, spends the New Zealand winters in the United States with his children and grandchildren.
It is because of him that she ended up studying for her certification in professional floral design in America.
She had grown up in Queenstown, helping out at the Kiwi Birdlife Park, owned by her family, and then moved to Wellington to work at the zoo.
Rather quickly she found herself working in the film industry and as part of that obtained a diploma in scuba diving instructing and marine studies.
That saw her scuba diving somewhere between Mexico and Cuba, which is where she met Mr Thiel, a commander of the sergeant major training academy at Fort Bliss, Texas.
"One minute I was running around chasing kiwi and kakapos then I'm on a military base seeing coffins come back from Afghanistan and Iraq."
It was while living on military bases that she turned her hand to working in floristry.
"My husband was in the military when the US was at war and on a military base it is a pretty stressful environment to be around and I couldn't do animal work because we were always moving around ...
"I liked flowers and wanted to do something nice and to get away from the stress and aggression of war.
"I seemed to have a natural ability [with floristry].
"I just love working with flowers ... as a florist you get to see all the happy times and all the sad times in people's lives."
Those people have included some big celebrity names, as well as American governmental figures, though she said she could not say who they were, for reasons of privacy.
She will return to New Zealand at the end of this month and will reopen her shop, Bloom, on July 2.
She said she hoped to be able to bring back some new ideas and trends and then set up a similar workshop here.
"We are very lucky that we have a lot of good florists in Otago. We have some really really talented people in this area," she said.
