Meet the grower, trainer, and caretaker
NorCal Iris Gardens and Top O’ the Line Farm share one home, one pair of hands, and one belief: raise every plant and animal with patience, practical knowledge, and genuine care.
A Northern California original
Holly Singleton is the owner and trainer behind Top O’ the Line Farm and the grower behind NorCal Iris Gardens in Redding, California.
What began with horses and a love of the outdoors grew into a wonderfully diverse farm: registered Haflingers, riding and training programs, miniature horses, llamas, peafowl, specialty chickens, and rows upon rows of iris. Holly’s old farm records preserve decades of bloodlines, foals, show horses, lesson horses, and trusted family companions. The iris garden carries that same attention to detail—every rhizome is handled, inspected, and prepared by hand.

Explore the aviaryThe Three Shastas
The farm sits in Redding near Mount Shasta, Shasta Lake, and Shasta Dam—the “Three Shastas” that shape this corner of Northern California. Hot, dry summers, cool wet winters, and volcanic soils create a place where strong iris and hardy farm animals thrive.
Beyond the barn
Holly’s farm family includes registered Haflingers, miniature horses, gentle llamas, peafowl, guinea hens, and specialty chickens. Each group now has its own page, ready for the current photos and updates Holly shares next.
