Wayside Gardens Signature Product Butterfly Burst Icon

This superior clone of the Blue Mist Shrub was selected at Longwood Gardens in Pennsylvania for its upright growth, long bloomtime, heavy flower production, and superb silvery foliage. A garden standout that needs little attention to look its best for years, 'Longwood Blue' is a fine addition to the sunny to partly shaded garden!

This shrub is 2 to 4 feet tall and wide, creating a big impact even in a small space. As a long, glorious hedge (as pictured here at Longwood Gardens), it is breathtaking. Butterflies can't resist these blue blooms, adding even more color to the garden!

'Longwood Blue' blooms most heavily from midsummer into fall, continuing through those late-summer doldrums that can make a garden look spent. Its flowers are a rich, hard-to-find shade of blue, and make fine cut flowers. They're nicely complemented by the silvery hues on the foliage!

Upright and never sprawling or rangy, 'Longwood Blue' is an altogether superior selection of the beloved Blue Mist Shrub. Give it a try in your garden this season!

Space shrubs 3 to 4 feet apart in well-drained soil in full sun in the North or partial shade in the South. Zones 5-9.

  • Butterflies like a lot of sunlight, so locate your garden in a sunny area.
  • If you live in a windy location, plant your butterfly-attracting plants near a building, fence, or hedge to protect them.
  • Plant a variety of nectar-rich plants, as well as shrubs and evergreens for shelter.
  • Since many butterflies and native flowering plants have co-evolved, try to put in some that are native to your area. The Lady Bird Johnson Wildlife Center provides lists of plants native to states and regions.
  • Certain colors are particularly attracting to butterflies – red, yellow, pink, purple, or orange blooms that are clustered or flat-topped, with a short flower tubes are especially attractive to adult butterflies.
  • Avoid using pesticides, especially around nectar-producing plants.
  • Provide a shallow source of water – try a birdbath with pebbles lining the bowl.
  • Place a rock in a sunny spot for butterfly basking and resting.
  • Create a "puddling area" by digging a shallow hole filled with compost or manure where rainwater will collect and release essential salts and minerals.
  • If you want butterflies to breed in your garden, put in some caterpillar food plants, such as parsley, milkweeds, asters, thistles, violets, clover, grasses, and Queen Anne’s Lace.
  • Since butterflies need nectar throughout the entire adult phase of their lives, try to create a design that will allow for a continuous bloom – when one stops blooming, another starts.

Deer Resistant Trees

As the deer population has boomed and food has become scarcer, they have become more aggressive. In some areas deer will strip your garden bare, leaving nothing green or flowery behind. While there is no such thing as a completely deer-proof garden, there are some effective things you can do to protect your garden from these hungry animals.

Use physical barriers


A High Fence
Deer can jump pretty high, but a fence higher than eight feet (higher on an up-slope) and flush with the ground will keep any deer out.

Electric Fences
They are a much easier and less expensive solution. Deer generally will not try to jump electric fences, but will rather try to climb through the wires, receiving a deterring shock.

Bird-Netting
An even less extreme physical option is to put bird netting over your larger and more susceptible plants.

Plant Deer-resistant Varieties

Herbs, some conifers, and many flowers are some of the best deer-resistant plants. More fragrant plants will often deter predation. Planting just a few deer-resistant plants will limit grazing of your other plants. Remember, "deer-resistant" does not mean deer-proof. A hungry animal will eat just about anything.

Having a dog In the Family

Dogs Keep Deer Away Owning a dog, especially a big dog will almost always keep deer from approaching your home. Just the scent of the dog will keep most deer away, and if your dog lives outside you will probably never see any deer.

For most gardeners, it is a combination of different solutions that works best. Every gardener has to find the solution that works best in their garden.

A Tradition of Distinction

Wayside Difference Since its founding in 1920, Wayside Gardens has brought the rarest and highest-quality plants to the garden market. Wayside was founded in 1920 by two acclaimed growers who came together to pursue their shared vision of marketing all high-end plants for the serious garden enthusiast. Originally located in Mentor, Ohio, Wayside Gardens swiftly grew a reputation for the highest-quality plants and the most sophisticated clientele. In 1975, Wayside was purchased by the Park Seed Company, and moved to Hodges, SC.  The company has flourished since then, growing to become an undisputed leader in rare and unique plant growing.

Unparalleled Selection

Wayside's horticulturists travel the world in search of new and unusual plant cultivars and proudly offer the garden industry’s most sophisticated selection of high quality and rare perennial plants, bulbs, trees, shrubs, roses, vines, and indoor plants. Beginning with ties to the Dutch family bulb business in Holland, our horticulturists have developed close relationships with perennial and bulb growers throughout the United States and Europe, providing access to many rare and unique garden treasures. Throughout our history we have had the pleasure of introducing numerous exotic foreign and domestic plant cultivars to the American garden market.

Tips for gardening in particularly hot, dry climates:


1. Water with a drip system whenever possible – soak the bed slowly and thoroughly to a depth of 10" to 12".

2. Watering deeply every 3 to 5 days is preferable to a shallow daily watering.

3. Water in the early morning, so foliage has time to dry.

4. Add a 2- to 3-inch layer of mulch or similar material to aid in water retention and help keep the roots cool during hot weather.
