Perennial Gardens was established by Linda Grieve in 1996 to fill a need in the Des Moines Iowa landscaping community - to design, install and maintain gardens. In 1997, with the addition of a Landscape Architect and crews highly skilled in plant material and hardscape installation, the firm expanded to become a full-service landscape design-build-garden care firm. Not only do we offer Iowa home landscape design and Iowa garden design services, we also offer Des Moines garden maintenance services. * Design* Build* Garden Care* EducationPerennial Gardens by Linda Grieves, Inc creates distinctive outdoor spaces by blending fine design, superior plant knowledge and quality hardscaping.Address: Perennial Gardens Directions: I-35 South exit 92 in Ankeny.
