Culture

Best grown in rich, medium moisture, well-drained soils in part shade. Tolerates full sun only if grown in consistently moist soils. Soil pH affects the flower color of most cultivars except white (blue in highly acidic soils and lilac to pink in slightly acidic to alkaline soils). Add aluminum sulfate to the soil to make the flowers bluer or add lime to the soil to make the flowers pinker. Begin soil treatments well in advance of flowering, as in late autumn or early spring. Plants generally need little pruning. If needed, prune immediately after flowering by cutting back flowering stems to a pair of healthy buds. Prune out weak or winter-damaged stems in late winter/early spring. Best to mulch plants year-round with 3" of shredded bark, peat or compost. Winter hardy to USDA Zone 6. For added protection, however, plants grown in USDA Zone 5 should be sited in sheltered locations and given additional winter protection, as needed, for the purposes of minimizing the risk of loss of significant numbers of flower buds or possible die-back to the ground in an extremely harsh winter. A burlap wrap of stems or circle of chicken wire filled with leaves or straw to 8-12" are time-consuming and visually unattractive landscape options, but can be effective. Regardless of protective measures taken, most bigleaf hydrangeas simply will not bloom (or will bloom poorly) in some years because of a variety of winter occurrences beyond the control of the gardener (e.g. low temperatures, sudden wide temperature fluctuations, icy conditions, late frosts). Some newer cultivars have been selected that flower on both old and new wood. Their pruning and flowering can differ from that of the species.

Noteworthy Characteristics

Hydrangea macrophylla, commonly called big leaf hydrangea, is a deciduous shrub with a rounded habit that, in the St. Louis area, typically grows 3-6’ tall and as wide unless damaged by harsh winters or pruned smaller. It generally features serrate, obovate to elliptic, dark green leaves (4-8” long) and large clusters of long-blooming summer flowers in either lacecap form (flattened flower clusters of small fertile florets with scattered showy sterile florets often forming a marginal ring) or mophead form (globose flower clusters of mostly showy sterile florets).

The genus name Hydrangea comes from hydor meaning "water" and aggeion meaning "vessel", in reference to the cup-like capsular fruit.

Specific epithet comes from the Greek words makros meaning large and phyllon meaning leaf in reference to plant leaves.

‘Fasan’ (translates from German as pheasant) is a lacecap cultivar. It is a member of the Teller Series of hydrangeas (Swiss series of lacecaps featuring names of native European birds), and is sometimes commonly sold as 'Teller Red'. It grows to 3-5' tall and as wide, and typically blooms on old wood (flower buds are produced the previous fall and overwintered). As the 'Teller Red' name suggests, this plant tends to bloom pink and is often grown in alkaline to neutral soils for display of pink to rose-red florets. The showy sterile florets are very large, generally forming an outer ring around the tiny fertile florets. This shrub may also be grow in acidic soils for display of blue florets. Regardless of the soil pH, florets tend to gradually change color as they age.

Problems

Some susceptibility to bud blight, bacterial wilt, leaf spot and mildew. Aphids are occasional visitors.

Uses

Group or mass in the shrub border. Also a good specimen or accent for foundations and other locations near homes or patios. Hedge. Containers.
