Mission Hills Nursery draws from a long tradition of horticulture, as it was founded in 1910 by renowned green thumb and urban-green-space advocate Kate Sessions. Year after year, rows of roses, shrubs, and vegetables have sprung up under the staff's doting hands and dangled morsels of plant food. A section for gardening accessories equips yard workers with trowels, thorn strippers, and organic fertilizers to motivate crops without scourging them with caustic chemicals. In addition to tending to its plants, Mission Hills Nursery's staff arranges landscapes with garden-design services and teaches clients to arrange their own through gardening classes.
