All through the long winter, I dream of my garden.

On the first day of spring, I dig my fingers deep into the soft earth.

I can feel its energy, and my
spirits soar.


— Helen Hayes 

A Wee Bit About Kate

When Kate lived in Denver, CO, she discovered botanical art and colored pencils while attending Denver Botanic Gardens School of Botanical Art and Illustration. About that same time Kate took the leap in quitting her marketing job and establishing her own business, Plant Manager Studio, LLC; a conglomeration of art, design and gardening. Since moving back to her native land of Maine in 2011 her business has grown in all aspects and there isn’t a day she regrets leaving the corporate world behind.

Every landscaping season is focused on plants, gardens, and making her clients happy with their home gardens. Every winter she can sit down at her drawing table and focus on depicting many of the plants she nourishes in the landscaping season, or better yet ones she discovers while traveling. Kate’s chosen medium of colored pencils fulfills her desire to capture the wonderful, fine details of plants layer upon layer and make it seem as if an observer of her painting could pluck the subject right off of the paper.

“Those who contemplate the beauty of the earth find reserves of strength that will endure as long as life lasts. There is something infinitely healing in the repeated refrains of nature — the assurance that dawn comes after night, and spring after winter.”
