Armstrong Garden Centers operates a full-service garden nursery and landscape design studio at 2840 Via De La Valle, Del Mar, CA 92014, situated between Flower Hill Promenade and the El Camino Real intersection. The company traces its roots to 1889 when founder John Armstrong began growing eucalyptus and olive trees in Southern California, and it became employee-owned in 1989. Armstrong now runs 27 locations across the state, with the Del Mar outpost offering a lush selection of annuals, perennials, shrubs, trees, houseplants, succulents, pottery, soils, fertilizers, and pest management solutions curated for the coastal San Diego climate. Every outdoor tree and shrub sold at Armstrong carries a lifetime guarantee, a policy that sets it apart from big-box competitors. The Del Mar store provides in-home landscape design consultations where a certified horticulturist walks your property, discusses preferences, lifestyle, and budget, and then creates a custom plan. Landscape installation, garden consultations, and individual planting services are also available. Regular in-store workshops cover topics like spring edible gardening, fruit tree care, and growing vegetables in a Mediterranean climate. Gelson's Del Mar is directly across the street for shoppers looking to pair plant shopping with a gourmet grocery run on the same Via De La Valle corridor. Neighbors on Nextdoor consistently cite the helpful, knowledgeable staff and the higher-quality plant stock compared to chain retailers. Armstrong Garden Centers Del Mar is open daily from 8 AM to 6 PM and accepts all major credit and debit cards.
