The cold-hardy Frost Proof Gardenia shrub is known for not losing fragrant blooms even in unexpected freezing weather. If you’re looking for a great hedge or foundation plant that won’t lose its flowers even after late spring frosts, this bush will work perfectly. The gardenia shrub grows in an upright growing habit that supports shiny, dark green leaves and beautiful-smelling white, 2- to 3-inch flower bulbs. This gardenia smells awesome while in bloom. The gardenia jasminoides does best when grown in more direct, full sun compared to other gardenia varieties but can grow in partial sun or morning sun with afternoon shade if in extreme temperatures with cold snaps. The plant will thrive best in well-draining soils.
