Description

Variegated Pink Winter Daphne is a superstar of an evergreen flowering shrub. When Winter Daphne begins to bloom in late winter it heralds – with its intoxicating perfume – the promise of spring. Its attractive, glossy, evergreen, deep green leaves are edged in gold on dense shrubs reaching about 3 to 4 feet in height with an equal spread over time. The highly fragrant blooms of Variegated Winter Daphne are crystalline white inside and purplish-pink outside. Winter Daphne usually begins blooming sometime in January or February (depending on climate) and continues through March or April. The flowers are good for cutting and last well in a flower arrangement. Winter Daphne is ideal for use as a specimen, in groupings, or as a natural evergreen hedge in shady landscape borders and woodland gardens. They are excellent for use under the canopies of large shade trees or planted near windows, patios, decks, porches and other outdoor living spaces where the wonderful fragrance can be enjoyed.

PLEASE NOTE: Daphne are one of the easiest plants to take care of once established, however, to achieve successful establishment it is very important to plant them right. When planted in the right spot that meets their specific cultural needs they will thrive. This is not a plant for the faint of heart, as they can die easily if not planted or taken care of properly during the establishment period.

Here are some tips that will help you to have the most success in growing Daphne…

Planting And Caring For Winter Daphne Plants

Despite the remarkable variety of gardening myths about its requirements, established Winter Daphne is very hardy and easy to care for in your garden. That said, Daphne plants much prefer growing in the ground than in containers. Though some have had long term success growing Daphne in containers, we advise against it. Also note that Daphne do not like to have their roots disturbed, so choose what will be a permanent planting site and be careful to disturb the roots as little as possible during the transplanting process.

Here’s a breakdown of what you need to know…

Cultural Preferences

Soil Preferences

Winter Daphne will thrive a wide variety of soils of average fertility, including amended clay. It prefers a moist, humusy, sandy, very well-drained soil. As with so many other types of ornamental shrubs, constantly soggy or wet soils are problematic. So make sure to plant your Winter Daphne in well-drained soil. Daphne much prefer growing in the ground than in containers. Though some have had long term success growing Daphne in containers, we advise against it.

How To Test Soil Drainage

If you are uncertain about soil drainage in the area you intend to plant your Winter Daphne, it’s well worth taking the time to test the drainage before planting.

To test soil drainage, dig a hole 12″ wide by 12″ deep in the planting area. Fill the hole with water and let it drain. Then, after it drains, fill it with water again, but this time clock how long it takes to drain. In well-drained soil the water level will go down at a rate of about 1 inch an hour, which is fine for Daphne. A faster rate, such as in loose, sandy soil, may signal potentially dry site conditions, which is fine for Daphne. A slower rate indicates poor draining soil and is a caution you need to improve drainage, plant in a raised mound or bed, or look for plants that are more tolerant of wet or boggy conditions.

Soil pH

Winter Daphne grow best in a slightly acid to neutral soil ranging from 6.0 to 7.0 on the pH scale. Most average garden soils fall between a pH range of 6.0 to 7.0.

Testing Soil pH

Soil pH is a measurement of the alkalinity or acidity of soil and is measured on a scale of 1-14, with 7 as the neutral mark. Any measurement below 7 indicates acid soil conditions, and anything above 7 indicates alkaline. If you’re unsure about the pH of your soil, and whether or not it’s suitable for growing Winter Daphne, it’s a good idea to test the soil pH in the planting area.

You can quickly test soil pH with an inexpensive soil pH tester probe. To raise the pH (make more alkaline) you can add pelletized limestone to the soil. To lower the pH (make more acid) you can apply Soil Sulfur, Aluminum Sulfate, or Chelated Iron. Adding organic compost to the soil or using compost as mulch can also help to increase acidity and maintain acid soil conditions.

Light Preferences

Winter Daphne thrives in part shade to deep shade. They don’t like direct sunlight during the afternoon. Early to mid morning and evening sun or all-day heavily filtered sun to full shade are okay. Morning sun with afternoon shade or all-day dappled shade is fine. Avoid exposure to direct afternoon sun.

How To Plant Winter Daphne Shrubs

Scroll down for container planting instructions

Step 1

Start by digging your planting hole at least two to three times as wide and as deep or not much deeper than the root ball of your plant. The wider the hole the better. Place native soil removed from planting hole around the perimeter of the hole, in a wheel barrow, or on a tarp.

Step 2

Depending on the type, fertility, and porosity of the soil in the planting area, it may be beneficial to amend the native soil. When planting in heavy clay soil mix bagged top soil or a good planting mix at a 50/50 ratio with the soil to enhance porosity and ensure good drainage. If the soil in the planting site tends to stay wet for a while after a rain or irrigation, consider planting in a raised mound.

Step 3

To remove your Winter Daphne plant from the nursery container it was grown in it is best to use a snipping tool to cut the container away. Daphne do not like to have their roots disturbed, so choose what will be a permanent planting site and be careful to disturb the roots as little as possible during the transplanting process.

CAUTION: There is no need to loosen feeder roots before planting. Damaging the roots can cause serious harm to the plant.

Step 4

Set your Winter Daphne in the planting hole so that the top edge of the root ball is slightly above ground level to allow for settling. It may be necessary to place some of your backfill soil mixture in the bottom of the hole to achieve proper planting height. When planting in soil that drains more slowly, to ensure good drainage and avoid wet soil, consider planting your Daphne in a raised mound.

NOTE: If the soil is poorly drained, which means it stays constantly soggy or wet for long periods after rainfall or irrigation, take measures to improve soil drainage or select another plant species more tolerant of wet soils.

Step 5

After setting your Winter Daphne in the planting hole, use one hand to hold the plant straight while using your other hand to begin backfilling the soil mixture around the root ball, tamping as you go to remove air pockets. Again, be careful not to damage the roots during the backfilling process. When you have filled the hole to the halfway point you can soak the soil. Then continue backfilling to the top edge of the root ball. To avoid suffocating your plant, avoid placing any soil on top of the root ball.

Note: If you are planting with the top of the root ball higher than ground level taper your soil mixture gradually from the top edge of the root ball to the ground level, as shown in the illustration above.

Step 6

Next, deeply water the planting area, including the root ball, to a depth equal to the height of the root ball.

Note: Allow soil to dry out before watering again.

Step 7
Apply a thin, 1/2 to 1 inch layer of shredded wood or straw mulch around your newly planted Daphne. Avoid the use of freshly chipped or shredded wood for mulch until it has cured in a pile for at least 6 months, a year is better. Avoid placing or piling mulch directly against the base of the shrub as this could cause problems with the bark.

How To Plant a Winter Daphne in A Container

Though some gardeners have had long term success growing Daphne in pots and other containers, know that they much prefer growing in the ground. Daphne growing in containers seems to suffer during the heat of summer when their roots are exposed to warmer air temperatures.

Winter Daphne plants growing in pots appreciate a damp to lightly moist but well-drained soil. Constantly soggy or wet soil is problematic. Therefore, when planting a Daphne in a pot or other container, we suggest using a pot with drainage hole and filling it with a quality potting soil or potting mix, or a 50/50 combination thereof. To ensure good drainage you can add 20% perlite or pumice to the soil mixture.

Choose a container that is large enough to allow for 2 to 3 years of growth before shifting up to a larger size container. This might mean your planting pot would be 4 inches or more in rim diameter than the root ball of your Winter Daphne.

Container color will matter as well. Not only will you want to pick a color of container that goes well with the flower and foliage color of your Winter Daphne, you’ll also want to pick a container that matches the style of your home or other structures and other plants in the surrounding environment.

Many nursery & garden centers offer a wide variety of containers to choose from. Before heading out to buy a container take pictures of your home and the surrounding environment. Doing so will help you to choose just the right color and style.

Container Planting Instructions

Step 1

Before filling your container with the soil mix, we recommend lining the bottom with shade cloth or a porous landscape fabric. This will keep the drain holes from becoming stopped up with soil or roots. If you place gravel or other materials in the bottom of the container lay the fabric over it.

Step 2

CAUTION: There is no need to loosen feeder roots before planting. Damaging the roots can cause serious harm to the plant.

Step 3

Pour a small amount of your soil mixture in the bottom of the container. Set the plant in the container and make necessary adjustments by adding or removing some soil so that the top edge of the root ball will sit 1/2 to 1 inch below the rim of the container.

Step 4

Backfill with your potting soil around root ball, tamping as you go, until the level of potting soil is even with the top edge of root ball. Again, be careful to disturn the roots as little as possible when backfilling.

Step 5

Water thoroughly until water starts to drain from the holes in the bottom of the container. Add more potting mix if settling occurs during watering.

Note: Allow soil to dry out before watering again.

Step 6 (Optional)

A thin layer of wood chips can be applied to soil surface for decoration.

How To Care For Winter Daphne Plants

How To Fertilize Daphne Plants

Winter Daphne are light feeders that when planted in a woodland environment can usually get most of not all the nutrients they need from the soil and decomposing leaves and other organic matter. If you must feed them, we suggest feeding very lightly after flowering with a slow-release shrub & tree type fertilizer or a mild natural, organic plant food. Though we do not suggest growing Daphne long term in containers, plants growing in containers can be fed lightly in spring with a slow-release or water soluble fertilizer listed for use in containers.

Soil pH

Winter Daphne grow best in a moderately acid to neutral soil ranging from around 6.0 to 7.0 on the pH scale. Most average garden soils fall between a pH range of 6.0 to 7.0.

How To Water A Winter Daphne Plant

Daphne require a well draining soil that never stays wet for too long. Constantly soggy or wet soil is a killer. Around 2007 scientists did research on Sudden Daphne Death Syndrome (SDDS) and found that Daphne as a species is highly prone to root rot infections. Since root rot is caused by soil borne fungi that are ubiquitous, meaning found everywhere in the natural environment, and these fungi become active on plant roots in wet soils, a well-drained soil and proper watering is vital for establishment and long term health of the plant. Young, recently planted Daphne plants prefer a damp to lightly moist soil. Established plants require little if any water, which is what makes them so easy to care for when established.

Tip: When watering with an automated irrigation system it’s best to set your timer to water during the early morning hours and not in the late evening or at night, which can lead to the onset of fungus and other foliar diseases. During the first few weeks after planting, check soil moisture often and adjust irrigation time if necessary to maintain a damp to lightly moist soil, not wet!

At Planting Time

Immediately after planting deep soak the soil in the planting area, including the root ball, to a depth equal to the height of the root ball.

During the First Active Growth Season

Newly planted Winter Daphne will need some water to establish themselves, but go light with the hose. Provide only enough water to keep the soil slightly damp. It’s best to allow the soil to dry out between each watering. Constantly soggy or wet soil is a killer.

Thereafter

When established, Winter Daphne are very drought tolerant and plants will require little or no water. Drooping leaves during a drought could be a sign that your Winter Daphne needs water. That being said, wet soil can cause wilting leaves. So always check soil moisture before watering. If the soil is damp skip watering.

How To Prune A Winter Daphne Plant

Because Winter Daphne does not heal well over cuts into mature wood (branches) pruning is best avoided. Prune only to remove a damaged branches as they occur or a stray branch that is spoiling the shape of the shrub. Make your cut just beyond the point of breakage or a quarter-inch above its origin (where it intersects another branch).

Plant Long & Prosper!

I have ordered many plants from Wilson Bros and like each one this plant arrived in perfect condition with all soil and moisture retained in the pot. They do a fantastic job of packaging that makes their plants survive any potential damage done by careless delivery people or any weather delays in transit. This plant will go into a large pot near our hot tub to display along with our other 2 Winter Daphne’s from Wilson’s to add some extra color all year as well as having evergreen foliage year round. Wilson Bros carries an unusually wide assortment of special plants not found at other online nurseries or most local retail sources. We will be life long customers and highly reccomend them.—————————————We are so glad you are pleased and we hope you enjoy them for years to come! Thanks for the great review!

The plant looked in great health on arrival, just like other Daphne bought elsewhere earlier this year, which died pretty quickly. With those I had been very careful not to disturb the roots. But this time I didn’t worry about that so much and removed as much potting soil as possible without breaking anything thicker than course hairs, and then planted in garden soil heavily amended with paving sand and bark fines. So far everything looks great with new growth now evident ——————————- WBG Reply: Hi Murph – Thanks you so much for providing your review of the Variegated Winter Daphne and we hope you enjoy it for years to come. Glad to hear you’re seeing new growth already. One difference between us and many other growers is that we hand-water every plant on our nursery…no overhead irrigation, which can often overwater plants causing constantly soggy soil and root rot. This is especially true with Daphne odora, which prefers a very well-drained damp to somewhat dry soil, especially when established. Let us know if there’s ever anything else we can do for you.

Yet again I received my shrubs from Wilson Bros via FedEx in terrific shape. I planted an entire backyard garden this Spring. Many of the shrubs I purchased were from Wilson Bros. I began with one or two but quickly added so many more to my purchases as I had increasing confidence in Wilson Bros quality and delivery. This shrub in particular, the variegated pink winter Daphne is beautiful. I can’t wait to see it flower in December; I have no reason to believe it won’t be spectacular given its current health and happiness in my garden. ——————– WBG Reply: Hi Marie – Thanks for your review of the Variegated Pink Winter Daphne and for the compliments!

I received this plant recently, it was very well packed – no damage to the plant whatsoever. When I opened the box, I am very impressed to find a nicely sized, healthy plant with big glossy leaves!! You never know when you order with an online nursery but this was my first order and I’m very happy. No flowers yet on my plant but the leaves are exactly as in the photo and I think I see some flower buds already. Looking forward to see how it’ll grow. Thank you Wilson Bros!! I will definitely be ordering more!! ——— WBG Reply: Hi Jae – Thanks so much for taking the time to provide your review and for the compliments! You’re right on the edge of where Winter Daphne is cold hardy, so, just to be on the safe side, I’d recommend planting yours in an area that will will buffer it from the north or west winter winds…maybe on the south or east side of the home or a screen planting of taller evergreen trees, or under a large tree. If temperatures are forecast to go below 10 degrees I’d put a blanket or some other covering over it for protection until temperatures rise. Some extra bark mulch will help protect roots from the cold…just thin the mulch when spring arrives. When established, it should handle temps down to 0 degrees F.
