How To Grow Hebe Shrubs

About Hebe Shrubs

Original to New Zealand, hebe shrubs can thrive in U.S. growing zones 7 through 11, doing best in locales with warm summers and mild winters. Though they’re in a genus of their own now, the plants formerly belonged to the Veronica genus—hence the still-used common name of shrubby veronica. There are some 100 species of hebe, plus many cultivars. Flowers may be white, red, pink, purple, or blue. Leaves, too, run the gamut from bright green and blue-green to maroon, purple, and gray.

Tips for Growing Hebe Shrubs

Select a species

Choose hebe shrubs that best suit your garden design goals. For a tall hedge up to six feet high, consider Hebe Variegata, with its rounded shape, purple blooms, and cream-edged foliage. The Grace Kelly cultivar has similar flowers and leaves but is shorter, topping out at three feet. Wiri Blush sports dark green leaves and striking hot pink blooms, while more demure Western Hills has silver-gray leaves and white or pale lavender flowers. Also keep in mind that compact varieties with small foliage, such as Baby Bush and Baby Marie, fare better in colder climates than large-leaf species.

Plant properly

Pick an area that gets lots of light or at least partial sun. Too much shade will likely yield a leggy look and poor flower production. If your area is prone to freezing winters, plant hebe where it will be sheltered but not crowded by other plants or a structure (e.g., close to the house). Moist (not wet), sandy soil that drains well is ideal, and the more neutral the pH, the better.

Don’t worry about water

Hardy hebe shrubs are fairly drought-resistant during much of the year. The exception is summer: Quench their thirst with about an inch of water weekly to encourage bountiful blooms.

Fertilize lightly

Given the right growing conditions, low-maintenance hebe shrubs don’t need much in the way of fertilizer. However, adding organic matter (some combination of compost, green manure, leaf mold, and/or animal manure) or slow-release fertilizer in early spring may help foster growth and blooms.

Don’t sweat the small stuff

Hebe isn’t particularly prone to insect damage yet will attract beneficial pollinators. Franciscana Blue Gem and Midsummer Beauty are especially tempting to bumblebees, butterflies, and other desirable garden guests. Hebe plants are also stoutly disease-resistant, though they may suffer downy mildew or septoria leaf spot in damp locales where circulation is poor. Smart planting can preempt these issues.

Prune post flowers

Once hebe shrubs have finished flowering, it’s time to prune to ensure that next year’s blooms will come back robustly. Aside from that, the plants’ naturally full, appealing form shouldn’t require much trimming. If a bush starts to get spindly, cut back about one-third to encourage a denser, bushier quality.

Propagate easily

Want more hebe shrubs? Simply snip a healthy three- to four-inch section and remove about an inch or so of leaves from the bottom. Moisten the end of the cutting and dip into rooting hormone to stimulate root growth, then plant in soil-less potting medium. Tamp down around the cutting, water lightly, and keep warm while avoiding direct sun at first.
