Hydrangea macrophylla

Updated: Nov 2, 2021

Hydrangea macrophylla is the quintessential representation of Victorian gardens. At least, its association with the Victorian era, for me, is due to its vast popularity as an ornamental in San Francisco, a Victorian aficionado's mecca. Winding down Lombard Street is a favorite experience of tourists, a serpentine street filled with H. macrophylla, thanks to Peter Bercut, who became fed up with the street's appearance and planted the hydrangea mass, according to History Daily. I need to research its association further with the Victorian era and History Daily's claim, because if the blogpost is correct, Becut's mass planting occurred in the 1940s, far past the City's Victorian period.

More succinctly, I have heard from countless people over the years that hydrangeas are "grandma plants." A simple online search using keywords "grandma, hydrangea" generated countless posts of the association, often including remembrances and nostalgia. A favorite plant among florists, it is easy to envision hydrangea gifts being planted along the foundation of someone's home, right there with Easter lilies and, if willing, poinsettias. The flowers last a long, long time, and if properly dried, can last even longer for use in dried arrangements, wreaths, and pressed flowers. How do I know this? Ages ago, I worked for the now semi-defunct garden shop, Smith and Hawken, way before Target purchased the brand. In its heyday in Marin and Stanford Shopping Center (where I worked, crossing paths with the likes of Steve Jobs and Martha Stewart), hydrangeas were a mainstay along with maidenhair ferns. Plop a couple in a fancy cachepot and boom, a sale! Okay, enough walking down the memory lane; should we continue to plant grandma's flowers?

From a landscape architect's point of view, H. macrophylla is a sturdy shade loving shrub that is fairly low maintenance, providing its given a lot of water. I note shade loving, but under the right conditions, such as Lombard Street with its coastal influences, hydrangeas tolerate sun. Despite its traditional associations, well-positioned specimens can enhance a garden composition, particularly since there are a number of cultivars for various tastes: 'Pia,' for example is a dwarf for smaller color statements. Lacecaps, with their flat topped flower clusters, gives a modern vibe. While bubblegum pink can be overwhelming for some, white, purple, or blue offer further options. Variegated forms are also available, lending their brighter foliage to a shady location. Still not convinced? Consider some other hydrangeas in the genus, such as H. quercifolia with its brilliant fall color, H. anomala petiolaris, a prolific, clinging vine, or H. paniculata, large enough to be trained as a small tree.
