Description
The award winning Tardiva Hydrangea is most noted for its beautiful long and pointed lacy clusters of white flowers that appear later in summer than other cultivars and continue well into fall. As cooler temperatures arrive white flowers will become tinted with pink. This wonderful H. paniculata (aka Pee Gee) is ideal for use as a specimen shrub or lower branches can be removed to form a highly attractive small single or multi trunk tree excellent for a magnificent focal point specimen just about anywhere in the landscape that gets full or part sun. For best performance, we recommend some afternoon shade in the deep southern regions of the U.S.
Landscape & Garden Uses
Growing in an upright rounded form 8 to 10 feet tall and 6 to 8 feet wide, Tardiva makes an impressive shrub or tree form specimen all on its own. That said, groupings and hedges of this cultivar are even more spectacular. Also a nice addition to mixed flowering shrub borders, as an accent in home foundation plantings, as a background in perennial gardens, and in large pots, planters or other containers of 18 inches or more in diameter.
Suggested Spacing: 5 to 6 feet apart for solid hedges; 12 feet or more apart for space between plants
Note: For our customers who live and garden north of USDA Cold Hardiness Zone 3a, where this Hydrangea variety is not reliably winter hardy, you’ll be happy to know that it can be grown in containers which can be brought indoors during winter and place back outside when temperatures warm up in spring.
Growing Preferences
Tardiva Hydrangea is exceptionally easy to grow when planted right and in the right spot. Almost any moist but well-drained soil of average fertility will do. Tardiva takes the heat at our location here in north-central Georgia but is also exceptionally cold hardy, withstanding even the coldest winter temperatures as far north as USDA Zone 3a, where it will also tolerate full, all day sun. In the South, zones 7 and below, it will tolerate full sun but might appreciate some filtered sun or dappled shade during the mid-afternoon hours. We suggest at least 5 hours of direct sunlight per day or all day lightly filtered sun for best flowering. Too much shade and plants become floppy with diminished flowering.
Note: Tardiva is a Hydrangea paniculata species that produces its flowers from buds that are formed on “new wood” (the current season’s growth). This means you don’t want to prune them in late spring or summer when they’re preparing to bloom.
