Betty-Ann (Ottersen) Brose was born in Norway and raised in Canada, spending her early years in remote, northern Ontario. From childhood, she developed a profound appreciation for nature and creativity, finding inspiration in both her family's garden and the time she spent outdoors. Her attention to detail in embroidery seamlessly transitioned into a growing passion for gardening and floral design.

Betty-Ann formalized her horticultural interests by studying at Longwood Gardens in Pennsylvania. She then embarked on a fulfilling fifteen-year career at Winterthur Museum, Library and Gardens, where her artistic abilities shone—especially during the museum’s renowned Yuletide celebrations.

During her time at Winterthur, Betty-Ann collected and dried a wide range of flowers and grasses, each year producing unique textures and colors. One of her most treasured responsibilities was decorating the museum’s impressive eighteen-foot Christmas tree. Along with the flower room staff, she arranged dried blooms and greenery with care and pride, knowing that her artistry would bring joy to countless visitors. These experiences underscored the deep, lifelong bond she nurtured between her hands and the natural world.

In 1999, Betty-Ann and her husband moved to The Woodlands, Texas, where they built a new home designed to showcase the garden. She continued her creative pursuits by attending classes at the Glassell School of Art and the Museum of Fine Arts Houston, earning certificates in painting and ceramics. In 2015, she participated in the inaugural BLOCK program for advanced students. All her artwork reflects her enduring relationship with nature.
