Second place “Blue Hydrangea flowers”
challenge WATERLILY, LOTUS & HYDRANGEAS group ~ 9 June 2010
That first Spring, when I moved into my new house four years ago, I knew that I wanted Hydrangeas across the front of my house. I dug up this horrible rocky soil to plant three of the most gorgeous Hydranges in front of my office window. They start out creamy white with a tinge of green, become this sublime shade of blue. Blue of course is my favourite colour. But she does not stop there. She turns pink, then lavender then in the fall she will become a kind of bronzy burgundy or purple. It is not unusual, at the end of summer to see at least five different colours on the bushes at the same time. This is my most favourite plant in my yard. Mine is on the north side of my house and gets very little direct sun except for the few hours before sundown.
Unlike other H. macrophylla cultivars, ENDLESS SUMMER blooms on both old and new growth and is winter hardy to U.S.D.A. Zone 4, all of which means that plants will, within their growing range, reliably flower each year, regardless of winter temperature, and do not need to be covered with burlap in winter. Best grown in rich, medium moisture, well-drained soils in part shade. Tolerates full sun only if grown with consistently moist soils. Soil pH affects the flower color (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. Prune after flowering by cutting back flowering stems to a pair of healthy buds. Prune out weak or winter-damaged stems in early spring.
