©2007 S.R. CalefThis is an old-fashioned beauty that lost popularity for a while, but came back on the home landscape scene with a vengeance. Back in the mid 80's, conversing with an experienced plantsman about 'Tardiva', I remember his delight at seeing its reintroduction. More familiar with the ever-popular H. paniculata 'Grandiflora', I immediately went seeking more information on this plant. The more I learned, the more enthusiastic I became. Hardy to Zone 4, fairly free of insect and disease problems and a fine addition to the mixed shrub border. Finally, just 4 years ago, I added 'Tardiva' to my plant palette. While 'Tardiva' can be trained to tree form, it more effective as a multi-stemmed specimen.
©2007 S.R. CalefWe've been concentrating on late-season color, of late, and this hydrangea does not disappoint.
Listed in most references as blooming in September, mine usually starts in mid to late August and continues through September. Like the other paniculata hybrids, the blend of sterile (most showy) and fertile flowers are borne in clusters, or panicles. Most are of a rounded, conical shape. 'Tardiva' bears just enough of the showy sterile flowers, to make the 8" upright conical heads really stand out in the fall garden. And like others of its species, it starts out a snowy white, gradually changing to pink, deep raspberry and finally to rust, with the onset of cooler weather.

©2007 S.R. CalefIs this hydrangea right for your fall garden? Let's see. Full sun to partial shade, Zone 4 hardiness, not many pests, organically-enriched soil (use your compost) that is well-drained, moderate moisture and a little annual pruning. Not that demanding!
'Tardiva' blooms on new wood, which means it can be pruned in late winter or early spring, unlike the H. macrophylla (mop-head) species. It probably looks best maintained at 6-8 feet high by 6 feet wide. 'Tardiva', left on its own, may reach 10-12' (I've seen an old, neglected 15' specimen). Just before the snow flies, I trim back spindly outer growth and old flower heads. This gets the plant through winter with a minimum of breakage. In early spring, I prune more severely, above dormant buds, creating a pleasing, somewhat rounded outline. An early spring feeding of organic fertilizer helps to push out strong, new growth and flowering wood.
Like most late bloomers, 'Tardiva' attracts a few butterflies, along with lots of bees and other pollinators. Nectar sources dwindle with the approach of fall. On this, and my other late summer/fall beauties, I have every sort of pollinator you can imagine. Bumblebees and honey bees are my best "customers." I am delighted to see all this activity - it's the sign of a healthy, well-planned landscape. I am likewise delighted to observe a steadily increasing honey bee presence, over the course of this season. I see five clustered together on a sunflower head, and feel hopeful that predictions of their survival may not be quite as dire as anticipated.
My relatively young landscape was designed to attract wildlife... this was priority one. Priority two, which just naturally follows, was to include ornamental plants. Food, nesting sites, winter protection and the beauty derived from plants and wildlife - what could be better?
But, I digress. Get thee to a local garden center and discover the beauty of Hydrangea paniculata 'Tardiva' for yourself!
