"I went out and bought a lot of pansies and photographed a lot of pansies because there are so many beautiful faces and designs on pansies," she told Daybreak South's Chris Walker.
"I fell in love with probably about 30 different ones and finally tried to narrow it down to my favourite photographs and favourite ones [to paint]."
The Kelowna, B.C., painter's quest began after she received an email from a Canada Post representative, saying he liked her work and asking if she would submit two paintings of pansies for consideration.
Koss says the only stipulation from Canada Post was that one of the flowers was the cold-hardy, purple icicle pansy. For the other flower, Koss decided to paint a blue pansy.
"Blue flowers in gardens are extremely rare, and I just love that there is a blue pansy."
Koss sent her paintings to Canada Post and an advisory committee decided they wanted to make her work into stamps.
"I thought, 'If I overthink this, then I don't know that I'm going to do a good job of it.' He linked my work for what I do naturally so I thought, 'I'm just going to apply the same thinking I do to my own art' … It worked, I guess."
Koss's stamps will be released on March 2.
