Oh boy -- an exciting new color for the best-selling, super-popular Double Cascade family of Petunias! Rich, deep Blue is the best color yet -- and the perfect complement to all the glorious pinks in this series!

If you're new to the Double Cascade series of Grandiflora Petunias, let me fill you in on why these plants are winning gardeners' hearts every day. Unlike older double-flowered Petunias, which tended to offer a few blooms (after considerable coaxing), the Double Cascades are just as floriferous as their single-flowered cousins, and the blooms are HUGE (4 inches). They tumble from tall planters, windowboxes, and hanging baskets, making a nice compromise between bedding Petunias, which tend to be more upright, and trailing Petunias, which grow straight down and out. It's the best of both worlds -- and you get these blooms UP TO A MONTH EARLIER than older varieties, for an extra-long season of color. You just can't beat them; they are simply terrific.

Now, let's look at the blooms themselves. They're frilly, petal-packed, 4 inches wide, fully double (which means that they have twice the petal count of single-flowered blooms), and elaborately ruffled, so that they resemble Carnations more than Petunias! And they erupt all over vigorous 15- to 18-inch-tall plants, creating a long, colorful show in the sun-soaked summer garden, patio, or porch.

Perfect for containers of any kind, this spreading plant froths out of hanging baskets, leans out of windowboxes, and tumbles from planters! It spreads 24 to 30 inches wide, with a well-branched habit that keeps you in blooms over a long, sunny season!

If you like new Blue, please take a look at the other colors in this wonderful series. There's rich Burgundy, bright Pink, pastel Soft Pink, and white-splashed Orchid Mist. Or simply give in to temptation and get the ultra-colorful mix of all 5 colors! This Petunia is so popular that we've even got a collection that gives you one packet of each color for less money than you'd spend on 5 separate packets!

Petunias are unrivalled for long-lasting color in the border, patio containers, windowboxes, and hanging baskets. They bring in the butterflies with their clear, glowing blooms, and are quite low maintenance. Start seeds indoors 5 to 6 weeks before the last frost date. Transplant into the sunny garden after danger of frost is past. Pkt is 35 seeds.

Petunia Germination Information

Petunia is the botanical name for Petunia
Petunia Seed Germination How to Sow Petunia:
  • Best sown indoors at a temperature of 70-75°
  • Sow 10-12 weeks before last frost and expect germination in 10 days
  • In order for seeds of double-flowered or F1 hybrids to germinate, they will need a temperature of 80°
  • In either case, sow with NO cover as light aids in germination
  • Petunia seeds are some of the only seeds that can be germinated in full sun
  • It is not recommended to sow seeds outdoors

How to Grow Petunia:
Transplanting: Transplant when there are at least two sets of true leaves

Spacing: Plant out after danger of frost is past at 12 inches apart in full sun and a rich, light, sandy soil with excellent drainage

Soil: Feed monthly with a balanced fertilizer. The single-flowered forms will tolerate alkaline and poor soils

Temperature: For best results, grow on under full sun at 65-75° days/62-68° nights, however plants are tolerant of higher and lower temperatures

Additional Care:  To keep plant growth in check, pinch plants back when 6 inches tall and again after the first flush of flowers. For conservatory culture: site in full sun, maintain 50° nights, and allow the soil to become dry between waterings

Appearance and Use:

Used in containers, hanging baskets, bedding, borders, and greenhouses. They are vigorous plants growing 10-18 inches tall and spreading to 3 feet. From summer to frost they are covered in slightly fragrant, funnel-shaped, double or single flowers that are bicolor or solid colors of violet, blue, red, pink, salmon, or white

Superior Germination Through Superior Science

Park's Superior Seeds Park Seed's humidity- and temperature-controlled seed storage vault Park Seed offers some of the highest-quality vegetable and flower seeds available in the industry, and there are a number of reasons for this.

First of all, we have humidity- and temperature-controlled storage, and we never treat any of our seeds with chemicals or pesticides. Nor do we ever sell GMO's (genetically modified seeds), so you always know the products you're buying from us are natural as well as safe for you and the environment.

Superior Standards - University Inspected

Testing seeds against minimum germination standards To make sure we are providing the best seed product possible and that our customers will get the highest number of seedlings from every packet, we conduct our own germination testing and have quality-control measures in every stage of our seed-handling operation. We hold ourselves to standards that are at or above federal and state standards, including testing specific crops more frequently than recommended by federal guidelines. And in order to maintain our organic certification, we welcome Clemson University to inspect us annually to make sure our organic seeds, which are stored and processed separately, are being handled properly.

Hand Packed By Experienced Technicians

Park Seed has been handling and packing vegetable and flower seeds for 145 years, a history that has given us a great understanding of how each variety should be cared for and maintained throughout every step of theprocess, from collection to shipping.

When packing our seeds, the majority are actually done by hand (with extreme care!), and we often over-pack them, so you're receiving more than the stated quantity.

The Park Seed Gold Standard

Park Seed's exclusive Fresh-Pak gold foil seed packets And many of our seeds are packed in our exclusive Fresh-Pak gold foil packets, which are lined to keep moisture out, so the seeds stay fresher for longer. We carefully pack very tiny or fragile seeds in crush-proof vials to ensure safe delivery to your home. Some of the small seeds are also offered as "pellets" (have a clay coating) to make sowing and growing easier.

When it comes to the kinds of seeds we offer, we are constantly seeking something new and provide many unique and hard-to-find varieties from all around the world. Our on-staff horticulturists are ready and available to share their expertise to help you with the success of these seeds, so you can grow a beautiful and productive garden!
Does Park sell GMO's or treated seeds?
GMO freeIt is important for our customers to know that Park Seed does not sell GMO or treated seed. We do buy a small amount of traditional hybrid seed from Seminis, a division of Monsanto Co., but that is all we purchase from them.

What are the differences between organic, heirloom, and hybrid seed?
Basically, organic seeds are seeds that are produced without the use and exposure to artificial/chemical fertilizers, insecticides, fungicides, herbicides, and other chemicals. They have to be grown, harvested, stored, and handled under very strict organic rules and procedures. All of our organic seeds are USDA 100% certified organic through Clemson University and the certificate has to be renewed yearly.

Heirloom Seeds are open-pollinated -- they are not hybrids. You can gather and save heirloom seed from year to year and they will grow true to type every year, so they can be passed down through generations. To be considered an heirloom, a variety would have to be at least from the 1940's and 3 generations old (many varieties are much older -- some 100 years or more!).

Hybrid seed are the product of cross-pollination between 2 different parent plants, resulting in a new plant/seed that is different from the parents. Unlike Heirloom seed, hybrid seed need to be re-purchased new every year (and not saved). They usually will not grow true to type if you save them, but will revert to one of the parents they were crossed with and most likely look/taste different in some way.

What are pelleted seeds? Why do you use them? How do I handle/sow them?
Pelleted pentas seedsExtremely small seed such as Petunias and Pentas are shipped as pelleted seed to make them easier to handle and sow. Pelleted seed are coated, usually with clay, to make them larger in size. After sowing, the coating will dissolve when wet and the seed will germinate. Pelleted seeds are shipped in vials placed inside seed packets, which protects them from being crushed. When sowing, be certain to use thoroughly moistened soil, to be sure that the clay coating absorbs enough moisture to dissolve. For sowing pelleted Petunia seeds, place the seeds directly on the soil surface and do not cover with soil, as light aids in the germination.

What is ideal temperature to germinate most seeds?
The ideal temperature to germinate most seeds is approximately 70 degrees F; give or take 1-2 degrees either way. This would be a good germination temperature for most flower and vegetable seeds and would be the most practical and feasible temperatures achieved for gardeners starting seeds in the home. You will notice for some seeds that it is recommended to use alternating day (warmer), night (cooler), temperatures, which is fine if one can provide such conditions. But most people are unable to provide those temperatures in a home setting, so just use the overall 70 degree F recommendation and the seeds should germinate well.

How long should grow lights be kept on per day and how close to the plants should the light be kept?
For germination and seedling/plant growth, you want to simulate the natural day-night cycles, and as a general rule, grow lights should be on 8-12 hours per day and off at night. You can vary this timing, as some seeds such as tomato, pepper, petunia, impatiens, and others, benefit from 14-17 hours of light per day (and the remainder of the 24 hour period in darkness). The most common grow lights used are fluorescent; using cool white, warm white, and wide-spectrum fluorescent tubes. These lights work well for germination and for growing plants up to a transplantable size. Fluorescent lights should be kept close though, 3-6 inches above the soil or the growing plants, adjusting the height as the plants grow.

How long will seeds keep in storage?
Park Seed stores seed in a special temperature- and humidity-controlled storage facility, which keeps seeds in excellent condition. Our seeds should be good for at least 1-2 years on average. Seed viability and storage time will vary depending on the seed item; some will keep a shorter time and some will keep longer. Seeds should be stored in a cool, dark, dry place. A basement will do (if not too humid), or a cool, dark room or closet. We recommend the best way to extend seed storage life is to store them in something air tight, such as a plastic zipper storage bag or canning jar, and place it in the refrigerator. This will extend the life of seeds for many years.

What is the best way to store seeds over a longer time period?
We recommend the best way to extend seed storage life is to store seeds in something air tight, such as a plastic zipper storage bag or canning jar, and place it in the refrigerator. This will extend the life of seeds for many years.

What depth should I sow various seeds?
When sowing seed outdoors, we recommend a maximum planting depth of 4X the width of the seed. When sowing seed indoors, the planting depth can be less, depending on the seed being sown, so it is always best to check specific directions. Here are some general guidelines concerning planting depth in relation to seed size: Tiny, dust-like seeds need to be sown on the surface of the growing medium or soil, uncovered, as they need light to germinate. The planting depth for small seed can be anywhere from barely covering, to 1/8-inch deep, to possibly 1/4-inch deep, depending on the recommendation. Medium seed should be planted at 1/4- to 1/2-inch deep, depending on the recommendation. Larger seeds can be planted 1-inch or deeper, depending on the recommendation.
