In fall the Instagram feeds many of our favorite gardeners, quite understandably, start to wither or move indoors. Not so that of Dutch garden designer Frank Heijligers. Indeed, much like the dames of imperial Russia, who, rather that retreating from the cold, donned furs and tiaras in anticipation of the social high season, Frank’s winter garden seemed to reach the height of its sparkling charm.
Enchanted, we decided to ask Frank, who grows grasses, perennials, trees, and shrubs at his nursery, PLANTWERK, to divulge his secrets for a successful winter garden. Here are 9 tips for adding sparkle and moody color:

“Successful winter gardens need a lot of plants with good structure in them,” says Frank. “The plants have to be strong and have more than one interest: nice foliage, bloom, color, seed head, change of color in fall, strong skeleton in winter.”

Fill the Gaps
Above: Because plants with good structure tend to bloom later, Frank notes that the successful four-season garden “starts with having a little more patience in spring.” To fill in the gap, he uses bulbs. Alliums, which maintain a sculptural seed head after they have gone by, are a good choice.
“Hosta or Alchemilla mollis are plants that look good early on in the year, but with the first bit of frost, they collapse,” Frank says. “You need plants like Phlomis, Aster, Eupatorium, Veronicastrum, and Anemone combined with grasses like Deschampsia, Miscanthus, Sporobolus, and Festuca mairei to make the garden look good until March.”
Bonus: birds love all the leftover seedheads in Frank’s hibernal garden.

Like many of the great Dutch gardeners that inspired him, such as Piet Oudolf, Dan Pearson, Tom Stuart-Smith, Dan Kiley, and Mien Ruys, Frank prefers structured perennials and textured grasses.

“[Along] with big plantings of perennials and grasses, I like to use cloud hedges of Beech or Cornus, for example,” Frank says. “Even though those plants lose their foliage (Beech keeps those nice brown-copper dried leaves), they provide a lot of structure in winter and early spring. The look of the garden is modern, with strong lines and focal points. When the plants begin to grow, you gradually loose those lines and you get a totally different-looking garden.”
The Charms of Decay

“After the blooming period comes the decay,” says Frank. “Every period has its own charm. And in February it’s great to cut it all back and start all over again with a clean slate.”

Frost Is Your Friend
