Endless Summer might well be considered the crown jewel among Hydrangea macrophyllas. This selection produces an uncommon sequence of large, showy, 8" diameter; mophead blooms until autumn frosts. Blooms, which are soil pH specific (clear pink in alkaline soil and blue in- acidic soil), occur not just, typically on old wood, but also new wood. Adding to the floriferousness is its superior cold hardiness, which has reigned supreme after 10 years of testing in the rigors of Minnesota's zone 4 winters. Endless Summer is the perfect choice as a specimen, foundation shrub, or in a mixed perennial border as it matures 3 '-5' tall and wide.

Genus Description Hydrangea is a genus of 80 or more species of deciduous and evergreen shrubs and climbers, rarely trees, found in wood­land in E. Asia and North and South America. Grown mainly for their large, showy flowerheads, many hydrangeas also have ornamental, flaky, peeling bark when mature, and attractive foliage with' good autumn color. The leaves are broadly to narrowly ovate, or lance­shaped, toothed, and either opposite or in whorls of 3. The flat, domed, or conical, terminal flowerheads consist of corymbs or panicles of both tiny fertile flowers and larger sterile flowers with showy, petal-like sepals. Hydrangea macrophylla (Bigleaf hydrangea, Florist’s hydrangea) is a rounded, deciduous shrub with broadly ovate, coarsely toothed, glossy, dark green leaves, to 8in (20cm) long. In mid- and late summer, bears flattened corymbs, 6-8in (15-20cm) across, of a few pink sterile flowers and numerous blue or pink fertile flowers. Cultivars of H. macrophylla are divided into 2 groups: Lacecaps have flattened flowerheads with small fertile flowers in the centers, surrounded by larger sterile flowers; Hortensias (mophead hydrangeas) have nearly spherical flowerheads of large sterile flowers. Flower color is affected by the relative availability of aluminum ions in the soil. Acidic soils with a pH of less than 5.5 produce blue flowers; soils with a pH greater than 5.5 produce pink flowers. White flowers are not affected by pH. Hydrangeas are useful for a range of garden sites: they are excellent as specimen plants or in group plantings, in a shrub border, or in containers. Use the climbers to clothe a shaded wall or fence, or grow up tree trunks. The flowerheads may be dried for use in arrangements. All parts of hydrangeas may cause mild stomach upset if ingested; contact with the foliage may aggravate skin allergies.
Care Tips
Cultivation Grow in moist but well- drained, moderately fertile, humus-rich soil in sun or partial shade; provide shelter from cold, drying winds. Some hydrangeas become chlorotic in shallow, alkaline soil. Pruning should be done in late winter or early spring, when dormant; some in late summer or early autumn to prevent bleeding of sap. Remove wayward or crossing shoots to maintain permanent, healthy framework.
Pests and Diseases Gray mold, slugs, powdery mildew, rust, ringspot virus, and leaf spots are common.
