Hydrangea serrata 'Iyono-usuzumi'
JAPANESE MOUNTAIN HYDRANGEAS are hale and hardy. Bud hardy yet very feminine. High maintenance? Not these ladies. In 10 years they have bloomed every year for everyone we have planted. They remain dormant longer and avoid late frosts. Generally they are somewhat smaller than the H. macrophylla.
H. serrata 'Iyono-usuzumi' A new and rarely offered selection from Japan known for its inky black flowers (So some of the photos offered suggest). We however came to our own conclusions and found them to be dark purple with dark blue veins. The heads of flowers of this selection are relatively small though for those with further breeding in mind, this new departure in flower color will offer plenty of inspiration.
Like their 'French' cousins they like good drainage, good soil and water and fertilizer. But you don't have to hover over them. Just plant them well to begin with and water once a week.
âÂÂGive them acidity, (sulphur) for better blues and alkalinity, (lime) for more pinks. Don't trim them. Just cut yourself some bouquets. Do yourself a favor...grow some of these. You don't have 15 years to
Zone 6-10.
