Since its introduction in 2009, the mouthwateringly named “Vanilla Strawberry” hydrangea (Hydrangea paniculata ‘Renhy’) has wowed gardeners with its magnificent blooms. Buds begin to open in the middle of the summer to reveal thick clusters of white flowers with reddish centers. The flower heads develop a wonderful, deep strawberry-red hue as they get older and develop a richer, deeper blush. The massive, cone-shaped blooms develop continually throughout the summer, giving this shrub a multi-colored appearance with stunning, new, bright-white blossoms that contrast with reddish-pink blooms. This well-known hydrangea type also has stunning crimson stems in addition to its distinctive rose coloration, which endures for several weeks. This magnificent shrub is simple to maintain and will grow throughout the majority of the country.
The Vanilla Strawberry hydrangea blooms in what month?
Midsummer sees the creamy white blossoms of Vanilla Strawberry change to pink, then a deeper red by late summer or early fall.
With a name like “Vanilla Strawberry,” it seems like hydrangeas have never been more popular, and how could one unique variety not be popular?
The French hybrid’s big pointed clusters of blooms, which emerge in mid-summer as a creamy white color before changing to pink, then a strawberry-and-white hue, and finally fading away in September, are what give it its trade name, Hydrangea paniculata ‘Renhy,’ the scientific name. A relative of the iconic PeeGee hydrangea, this shrub not only is a showstopper due of its dramatic hue but also its sheer size, which at maturity can reach seven feet tall and five feet wide. If the hydrangea’s two attractive features in the landscape weren’t enough to make any gardener drool, it also produces blooms that are ideal for cutting. It’s understandable why the American Nursery and Landscape Association named it one of the best plants.
This hydrangea’s one drawback is that it can be a little slow to bloom in the first few years—the proverbial “first it sleeps, then it creeps, then it leaps” scenario. However, if these requirements are satisfied, it can be a no-brainer addition to the garden:
Hardy in zones 4 through 9, but can be grown as an annual in other zones.
Most hydrangeas need full sun, with the exception of strong afternoon light. Give this plant morning and late afternoon sun, though it will also tolerate some shade.
It prefers moist but well-drained soil, but what about the soil? It may grow in any soil (sandy, clay, or normal), however bear in mind that the pH level may have an impact on blossom color.
When to plant: Hydrangeas should be planted in the fall or the first few weeks of spring when the soil is cool and the plants won’t be stressed by harsh cold or heat.
Pruning techniques include removing old stems and deadheading spent blooms so that the plant can concentrate its resources on promoting new growth. Prune shrubs in the late winter (the plant flowers on new wood), prior to the emergence of new growth.
Why aren’t the flowers on my Strawberry Sundae Hydrangea blooming?
Never give up! There are a number of causes for hydrangeas not to bloom. Frequently, the incorrect fertilizer is to blame. Use a fertilizer that contains more phosphorous than nitrogen for your Strawberry Sundae. On the NPK ratio, the center value should be greater than the other two. For more information on when and how to prune hydrangeas, see our hydrangea pruning guide. If you prune during the wrong season, you run the risk of removing the blossom buds. Additionally, make sure your hydrangea receives enough hydration and at least half a day of sunlight. Your hydrangea should bloom the next year if you follow these recommendations.
When ought my strawberry vanilla hydrangea to be pruned?
Unlike several other hydrangea variations, this kind blooms on new growth rather than stems from the previous season. This implies that when you trim your plant or when a late spring frost zaps all the flowers for the season, you don’t need to be concerned about removing blooms from the following season. Additionally, the blossoms that are still there at season’s end add interest during the winter; they will dry and take on a parchment tone. The best time to prune this hydrangea is after the worst of the winter’s cold has gone, most likely in February or March. This will help to remove the old flowers to make room for new ones and to promote fresh development. Every year, you can cut it back by as much as a third.
How should a Vanilla Strawberry hydrangea be winterized?
The ‘Vanilla Strawberry’ hydrangea blooms from the summer until the first part of the fall. Each stalk’s bloom is made up of many flowers grouped together. An inflorescence is a collection of flowers. The inflorescences develop into 8-inch-long pyramidal structures.
The individual flowers start out in July as white, changing pink as the season goes on, and eventually turning red. Hydrangea “Vanilla Strawberry” blossoms make excellent cut flowers. Cut and dry the blooms in the fall to preserve these eye-catching beauties for the winter.
Visit your neighborhood garden centers or nurseries to see if ‘Vanilla Strawberry’ hydrangea is on sale. When perusing, take note of the variations between the hydrangea Vanilla Strawberry and Pinky Winky blossoms. While ‘Pinky Winky’ produces taller, two-toned panicles, ‘Vanilla Strawberry’ produces shorter, cone-shaped flowers that are initially white. Give it some time if you see a strawberry vanilla hydrangea that isn’t turning pink; during the course of the season, the blossoms will transition from white to pink to strawberry red.
Many customers ask why their hydrangeas aren’t blooming. The primary reasons hydrangeas don’t bloom are incorrect pruning, bud damage due to winter and/or early spring weather, location and too much fertilizer.
There are hydrangea kinds that bloom on either fresh or old wood, or even both. Both new and old wood are the growth of the following year (spring), respectively.
- Consider that this year, you bought a Nikko Blue Hydrangea. For the next year, Nikko’s produce blooms in the fall. Your Nikko is therefore creating blooms this fall that will blossom in the spring.
- Therefore, you wouldn’t want to completely prune your Nikko Blue Hydrangea this fall while you are pruning your perennials. Pruning the Nikko Blue Hydrangea this fall would effectively mean cutting off your hydrangea flowers for the upcoming spring.
- The idea behind Endless Summer, a hydrangea variety that blooms on both old and new wood, is that the plant will set blooms this fall to blossom not only in the spring of the following year, but will also keep producing blooms in the spring of the following year to extend the blossoms into the summer.
- Once more, pruning your Endless Summer hydrangea in the fall would mean removing some of the flowers that would blossom in the spring.
The hydrangea’s plant tag will indicate whether it blooms on fresh wood, old wood, or both. It is typically preferable to wait until spring to prune your hydrangeas. As the plant grows, you’ll see stems that are fragile when bent and lack any leaves. Since these stems are dead and won’t produce any flowers, they should be clipped close to the plant’s base.
The second reason why your hydrangeas aren’t blooming is probably the weather. Buds of hydrangeas are extremely susceptible to cold. Therefore, it is a good idea to wrap your hydrangea for the winter if it is an old wood hydrangea. Keep in mind that old wood hydrangeas establish their blooms for the following spring in the fall. Therefore, you won’t have blossoms in the spring if the fall-produced buds are frozen in the winter.
You can wrap anything with regular burlap. Burlap should be wrapped around the plant and filled with mulch or leaves after the first hard frost and after the hydrangea’s leaves have dropped. In order for the buds to survive the winter and sprout the following spring, the plant receives insulation from this. Never wrap your hydrangeas in plastic. When warmer winter days arrive, the plant cannot breathe since plastic, unlike burlap, doesn’t breathe. As a result, the plant can heated to such high temperatures that it cooks within the plastic and perishes.
The second most frequent weather-related cause hydrangeas do not blossom is late spring killing frosts. We saw really chilly temperatures in April both this year and last year after beautiful spring days. When springtime temperatures drop below freezing, hydrangeas need to be covered with an old beach towel or sheet. Because of the temperature dip, there won’t be any blossoms.
The majority of hydrangeas require at least 3 to 4 hours of light per day to bloom. The best light is in the early morning, midday light is acceptable if it is dabbled light rather than beating sun, and afternoon sun is typically too hot. Check the plant label, though. Newer hydrangea cultivars are being created that can withstand more sun exposure time and sun intensity. A hydrangea in full sun will require much more watering than one in diffused light, so keep that in mind.
High nitrogen fertilizer should not be used to feed hydrangeas. Nitrogen is indicated by the first number on the fertilizer ratio. (The ratio stands for N, P, and K) For healthy leaves and general good growth, some nitrogen (N) is required; however, a ratio of 8-16-6 or any similar combination with a higher middle or phosphorus (P) value is preferred. The growth of roots and shoots is encouraged by phosphorus, which improves the blooming process.
Potash (K), the third element’s last quantity and the lowest ratio, is for plant hardiness. Because hydrangeas prefer acidic soil, they can be fertilized with fertilizers designed for such plants. Hydrangeas only require fertilizing twice a year, once in early spring and once in mid-summer. To avoid root burn, make sure the soil is always moist before applying a fertilizer.
How long does a hydrangea take to bloom?
There could be a number of causes for hydrangeas not to bloom. Since we can grow five different species of hydrangeas, some explanations vary based on which type it is.
But first, let’s cover the broad causes. The bush might not be fully developed for blooming. The majority of woody plants don’t bloom until they are rather mature. If a newly planted bush had flower buds when it was in a pot, it might bloom the first year. However, after that, it might not bloom for a year or two as it gets used to the soil in its new position. Instead of flower buds, it is actively forming new roots and branches. There will be a lot more flowers when it eventually starts to blossom again because the bush has indeed “bushed” out!
Sadder still, it’s possible that deer have devoured the flower buds. Where deer have pulled the buds off because they lack incisors, look for rough torn stem ends. Additionally, because all hydrangeas require moisture to thrive, blossoming may not take place if a drought strikes at the incorrect time.
The timing of some hydrangea pruning by gardeners has been off. At this point, determining the species becomes crucial. We have two species that flower on fresh wood (new growth of the current growing season). These include the panicle hydrangea, Hydrangea paniculata, also known as the PG hydrangea, which is frequently seen densely planted in cemeteries, and the native smooth hydrangea, Hydrangea arborescens, which is frequently sold under the cultivar name “Annabelle” and typically has white mophead flowers. Early spring is a good time to prune these two species, and the new growth will bloom later in the summer.
Our other three hydrangea species, however, only flower on aged wood (growth from the previous growing season). The native oakleaf hydrangea, Hydrangea quercifolia, with stunning crimson or maroon fall foliage color, the climbing hydrangea, Hydrangea anomala petiolaris, a fantastic vine for partial shade, and the majority of the highly popular blue or pink bigleaf hydrangea, Hydrangea macrophylla, are included. The flower buds will probably be removed if these plants are pruned in the fall or early spring. It is preferable to prune immediately following blooming, before the new flower buds emerge.
The bigleaf hydrangea has undergone a number of new types over the past few years. They bloom on both old and new wood, hence the name “remontant.” Growing these types will help one prevent a further cause of poor bloom. Flower buds on older, non-remontant types of Hydrangea macrophylla frequently die in our cold winters. However, gardeners who reside in urban areas or close to bodies of water, where the winters are less severe, frequently have success with these types. A winter with a thick layer of snow may also adequately shield the flower buds from the cold in rural areas.
What distinguishes Vanilla Strawberry hydrangea from Strawberry Sundae hydrangea?
The bloom color of Strawberry Sundae and Vanilla StrawberryTM will be similar, beginning creamy white and maturing to a lovely deep pink as evening temperatures dip in the fall. The size of these plants varies, with Strawberry Sundae being smaller than Vanilla StrawberryTM’s imposing stature. However, Berry White has a deeper red in the fall, so this might be your best option if you’re seeking for the most striking color. Give Berry White a try if you have the space; it is a little bigger and is around 6 feet tall, similar to Vanilla StrawberryTM.
What is the growth rate of Vanilla Strawberry hydrangeas?
Vanilla Strawberry Hydrangeas can reach heights of 6 to 8 feet and widths of 4 to 5 feet. After having had time to settle down, the plant may not achieve its full size until the second or third year. If you want to construct a dense continuous planting of Hydrangea plants, position them 4 feet apart, or wider apart if you want to leave some empty spaces surrounding the plant.
What should I feed hydrangeas to encourage blooming?
When purchasing fertilizer, check the labels to see how much nitrogen (N), phosphate (P), and potassium are present (K). A general-purpose, balanced fertilizer such a 10-10-10 N-P-K or 12-4-8 N-P-K is typically best for hydrangeas. Consider using a fertilizer with additional phosphorus if you want your hydrangea blossoms to be bigger and more numerous.
Since phosphorus is the middle element, fertilizer with the formula 10-20-10 will do. Choose a slow-release granular fertilizer with the designation “bloom boost” if you’re looking into it because it might also include more phosphorus.
