It’s time to level up your gardening game, but I don’t mean by planting standard yellow sunflowers and cherry blossom trees. You want your own personal flower garden to have some originality, right? Use night sky petunias, commonly referred to as galaxy flowers, to give your backyard an extraterrestrial makeover (literally).
No two night sky petunias are same; these flowers aren’t simply typical purple and blue petunias; they’re covered in white dots that make them appear starry at night. They are a definite way to add the cosmic flare your backyard garden needs.
It can be challenging to grow these celestial blooms because of how their behavior varies depending on the temperature of the soil in which they are placed.
Galaxy petunias are perpetual, right?
Petunia Care by Galaxy. Petunias are produced as annual flowers with a single growing season, yet in the correct conditions they can be perennials. They have a lengthy bloom phase and fast maturation.
Do night sky petunias reappear annually?
As annual plants, petunias only bloom during the growing season. Fortunately, once they begin to bloom, they will keep blooming for several months until the first fall frost. Petunias called “Night Sky” typically begin blooming in the summer and continue through the fall. Place them where they will receive at least six hours of daily direct sunshine in full sun. Your plants might produce fewer flowers if you use any less.
Although petunias can withstand drought, they don’t like to be planted in moist soil, so if you plan to grow them in your yard, be sure to pick a location with good drainage. Before watering them once again if you planted them in a container or hanging basket, allow the top of the soil to become dry to the touch (some planters could need watering every day).
Petunias also need to be planted in rich soil with lots of organic matter that will provide them with the nutrients they require because they expend a lot of energy to bloom practically continuously. Regular fertilization will also encourage the plant to continue producing flowers; for petunias grown in containers, fertilize every two weeks; for those grown in gardens, fertilize every three weeks. Since the spent flowers normally fall off on their own, they shouldn’t require much deadheading; however, if the stems start to grow too long halfway through the season, you can give them a gentle trim.
As the growing season proceeds, many of your blooms may vary since the pattern on each “Night Sky” flower is susceptible to temperature changes. Warmer temperatures tend to make the petals more purple, while cooler conditions tend to produce more white dots. Fall is typically the season when galaxy blooms are swirling with the most “stars,” as the weather begins to cool.
Follow the directions on the seed packaging if you wish to start the seeds yourself; typically, they must begin growing by late February. This year, it’s getting a little late to start seeds, but soon it will be time to sow mature plants. Don’t wait too long to place your order because most growers will begin delivering the plants in May, by which time many regions of the nation have already had their final spring frost. Mid-May to early June is generally the optimum time to plant these unique petunias in your garden.
From where come night Sky petunias?
This spring, when looking for annual plants for my containers, I came across a petunia unlike any other I had ever seen. It made me halt in my tracks. Just over head height, hanging baskets had purple petunias dotted with white specks that resembled stars at night:
So cool! These three petunias, which are still in bloom, hopped into my cart and traveled with me home. Early in June, I paired them with some white salvias in a planter on the side of the house. This image was taken on June 3rd:
Even though they only had one bloom that was somewhat spotted out of the others, the plants’ health and plenty encouraged me.
After a few weeks, they fulfilled every expectation I had. These images were taken on June 23:
I was quite happy to receive these unique new petunias. After considerable research in horticultural trade periodicals, I discovered that the Night Sky petunia is a very recent invention. As breeders worked to perfect the pattern, it was initially presented to retailers in 2015 but wasn’t put on the market until 2017 (note: I enjoy hearing this since often plants are pushed to market before they’ve really been evaluated and their traits and peculiarities are completely known).
Why Did My Night Sky Petunias Turn Purple?
I observed a significant pattern change as I grew this plant during the summer. In fact, I was speculating that this plant may have been rushed to market because scientists were still trying to figure out how to preserve the starry pattern.
Take a look at this photo from July 28:
After researching a bit, I discovered that the weather affects how intense the markings are. “[Night sky petunia] is vulnerable to the environment, so if it’s cooler, the white spots are greater and if it’s warmer, there is more blue/purple on the plant,” claims Greenhouse Grower magazine. That was reasonable. With warmer days and cooler nights in June, the petunias displayed fantastic color. There was minimal difference in temperature between day and night in late July.
In order to learn more about the shifting splotches on these petunias, My Modern Met, an online publication “that honors innovation,” wrote about them in 2017. Burpee, one of the biggest producers in North America, was then approached. “According to Burpee, a significant difference between daytime and nighttime temperatures will result in transient white coloring to form on the blooms,” they wrote. Therefore, you should try to keep your Night Sky Petunias warm during the day (about 100 F) and chilly at night in order to ensure that they are always sparkling (about 50F).
Right. There’s not a lot of likelihood that those circumstances will last throughout Toronto’s summer unless you transport your plants inside the air conditioning every night and back outside in the morning.
The heat continued as the summer progressed. On August 18, the plants were robust, although it was difficult to see the white stars:
Finally, the fall brought cooler nights, and the petunia skies began to shine once more. This image was captured on October 14:
The plants are beginning to wither a little bit, mostly as a result of a lack of water (this planter self-waters when the air conditioner is on, but when it’s not, the plants depend on me remembering to water them). When the air conditioner is in charge of watering them, they fare much better.) In comparison to the height of the summer, the color changes are unquestionably more noticeable.
I’ll admit that I was a little bummed out that the stars didn’t endure the entire summer. However, I still find it interesting that plant breeders were able to get specimens with this kind of marking.
How Was Night Sky Petunia Developed?
The romantically titled PH-2012-3582 and ‘Suprise Marine’ petunia types were crossed by breeder Antonella Capo in Latina, Italy, in April 2012, according to information I obtained on the website of the Canadian Food Inspection Agency1. “In Latina, seedlings were chosen in April 2013 based on the consistency of the bloom color pattern and plant quality. Between October 2013 and May 2014, the chosen seedlings were tested in several greenhouse trials for cold tolerance, plant growth habit, plant quality, flower color, and floral color pattern. In the fall of 2014, in Stuttgart, Germany, a single seedling of [Night Sky petunia] was chosen for commercialization.
The plant was tested in a greenhouse in St. Thomas, Ontario in the spring of 2018 before being introduced to the Canadian market. There, 20 plants were cultivated, and by the end of May 2018, they were compared against 20 plants of an existing variety. Before this petunia was released to other markets, I assume that comparable testing were conducted all over the world.
Where to Buy
Even though the stars lose some of their intensity in the summer heat, this petunia is still special and I think it’s worth growing once more. The following year, I’m hoping to find it in a nearby nursery. As word of its popularity grows, I anticipate it will be simpler to locate in nurseries.
Night Sky Petunia Seeds* are sold by a number of vendors on Amazon, but if you decide to go that route, I would advise you to do your homework to make sure you’re buying from a reliable source. The listings I found frequently mentioned “petunia bonsai, which is totally incorrect. These plants mature into large petunias; I believe the term “Bonsai was used in the description to entice customers because it has been demonstrated to perform well in online plant sales. Purchaser beware
SKYseries
I did learn that numerous additional colors will be entering the sky series from the breeders that introduced Night Sky to consumers. I spotted the “Pink Sky” variety at the nursery I was at:
Additionally, I discovered that my friends were cultivating Lightning Sky petunia during the Long Branch Garden Tour this summer:
As I want to investigate the other colors in the Sky series galaxy next year, I will have to ask them what nursery they found it at.
Cultivation
Looking for advice on how to grow Night Sky or other petunias from the Sky series? They grow very much like any other petunia, with the exception of what I’ve said above about keeping them slightly cooler at night. I have a post here on how to cultivate and take care of petunias.
On the plant tag that came with mine, there is the following growing information:
1CFIA is the federal agency in charge of regulating all foods and plants imported into Canada, and from what I can tell, their paperwork on Night Sky was used to assess whether or not it differed significantly from other types already sold there.

People who have used this fertilizer claim that it completely revived their plants in just a few days. Some customers claim that a small amount is effective and that their plants adore it.
Night Sky: What sort of petunia is it?
Petunia Night Sky blooms vary from one to the next. With their deep purple-blue petals and white-cream specks that alter in intensity with the temperature, these easy-growing, weather-resistant flowers like little views of the universe. Petunia Night Sky is a mounding plant that blooms continuously from late spring through autumn. It is compact and strong.
How can you ensure that petunias bloom all summer long?
It all boils down to how healthy your plant is. A Wave petunia can reach its full potential if it is given the right care. This denotes abundant and robust blooming.
The opposite is also accurate. Your Wave petunia plant might require a little more care if you discover that it didn’t get off to the ideal start or didn’t get the early attention it required.
Your Wave petunias might be able to recover, though, if you concentrate on some of the locations listed below.
Make sure they are getting plenty of sunlight
Petunias in general, including wave petunias, adore the sun. They will require at least six hours of sunlight, with a full day of sunlight being ideal.
Lack of exposure to sunshine may be the cause if you planted your Wave petunias in a shaded area and the plants aren’t flowering as you’d like them to.
Begonias are a common choice if you’re seeking for a plant that will still bloom even with less sunshine.
Wave petunias are frequently planted in hanging baskets by growers. One of the most often used plant species by gardeners for hanging plant arrangements. Simply relocate the container to a location where it will receive more sunlight if you are growing them in a hanging basket or pot.
Keep them wateredbut don’t overwater them
On the other hand, you might notice that your Wave petunias don’t bloom as much if they receive too much sunlight and insufficient water.
Make sure the plant is adequately watered because it needs sunlight and water to survive.
Checking the soil’s moisture in the top inch or so is a smart technique to make sure. It’s probably fine if the soil near the surface is at least slightly damp.
If you’re growing Wave petunias in a hanging basket, you can lift the basket to feel how much water it needs by doing so. If it is adequately watered, it should feel noticeably heavy, and if it is dehydrated, visibly light.
If overwatered, wave petunias are susceptible to root rot and other illnesses, so take careful to water them just enough to keep them healthy. Your Wave petunias will recover in this way and produce an abundance of blooms.
Fertilize the plants when needed
A water-soluble fertilizer should be added when necessary while watering. Wave petunias require nutrients, just like other plants, thus it’s critical to maintain a healthy fertilization level.
Follow the directions on any fertilizers you use, and consider the season. During the summer, when you might be watering every day, you might only need to water once or twice a week, but this frequency will probably change in the spring and fall.
If you neglect to fertilize the plants, Wave petunias are less understanding than Supertunias. You may tell they need more nutrients if you notice the vines starting to turn yellow.
Give them space
Make sure you give the space that spreaders like wave petunias need! It is advised that you plant them at least a foot apart because their vines may get up to 4 feet long.
When wave petunias are grown in containers or hanging baskets with restricted root space, they might not be able to reach their full potential and produce as many blooms.
Trim the plant to promote growth
Last but not least, pruning back your Wave petunias is a fantastic strategy to encourage the development of new flowers. Cutting back a plant when you want it to grow more may seem counterintuitive, yet it is frequently necessary when dealing with a straggly plant.
Treat it for budworms
It’s likely that despite your best efforts, the Wave petunias are still in bloom. The budworm might be to blame.
Budworms are an insect pest that wreak havoc on a variety of garden plants, particularly petunias.
If your Wave petunia plant is being affected by budworms, you’ll probably notice holes in the blossoms. These seem to be a problem in Pennsylvania in the late summer.
Budworm can be handled in a variety of ways. Thurocide has proven to be efficient in eliminating budworms and reviving Wave petunia blooms.
