Fleuroselect Gold Medal Winner 1988

It's hard for us now to look back and realize what an improvement Snow Crystals was over all other Sweet Alyssum varieties when it arrived on the scene in 1988. Until Snow Crystals, Sweet Alyssum was a rather delicate annual, nicely fragrant and everything but short-blooming and subject to fall apart a bit when faced with rough wind or high heat. You grew it in a container with the full expectation that it would bloom for a few weeks and then you'd replace it, around about July, with something tougher for the high heat and humidity of the dog days.

Then Snow Crystals changed everything. It was the first tetraploid Sweet Alyssum, which means that it has twice the chromosomes of older (diploid) varieties. Twice the chromosomes means LOTS more vigor, as well as specific improvements such as much greater heat and wind tolerance, larger flower size, and longer staying power. Suddenly you could create edging or even groundcover with Sweet Alyssum, because Snow Crystals all reach the same size, bloom at the same time, and stay put in all their glory for months, not weeks.

Snow Crystals was immediately awarded the Fleuroselect Gold Medal (an honor not often bestowed), and it has never been improved upon. How could it be, really? These -inch white blooms are so profuse that they form a neat canopy of color over the fresh green foliage. Their scent is ultra-sweet and pleasing, and lasts all season. They open in early summer and continue through the season everywhere, and often into autumn. And they form neat plants, just a few inches high when not in bloom but reaching up to 10 inches in flower, with a width of 8 to 10 inches too. Great in containers, beds, along the driveway, in street plantings, edging the foundation, and just about everywhere they can get full sunshine, they're trouble-free and so dependable.

Sweet Alyssum (also called Sweet Alison) is a great coastal planting, too. It loves the salt spray and doesn't mind sandier soils. It grow's readily from seed, and can be transplanted as soon as the soil has warmed and the nights are free of frost in spring. Every garden and patio container deserves this sweet-scented, pretty, pert little plant. Make Snow Crystals a central feature of your sunny spaces this season.

love the smell!

I start them indoors and they germinate well, I transplanted them against a west facing foundation, a very hot, sunny spot.. they petered out during the hottest part of summer but came back when it started cooling down a bit.Will put them somewhere else this year. They've been great in the past in not such a hot area.I'm still a fan, just wrong placement last year.

Solid performer, lovely fragrance

I chose this to attract beneficial insects, enjoy fragrance, and bloom continuously. My experience. Fragrance like honey, fast growing, reseeds, rebloom after deadheading, heat tolerant. Lovely plant and my coworkers want it now too!

Very good germination but slow grower
Bird Lover from IL wrote on July 14, 2016

I started these seeds indoors in early April and since transplanting the seedlings in early June they've grown very little in spite of regular watering and fertilizing. Some of the seedlings have started blooming but the plants are so small that the flowers are not showy at all. I grew Alyssum from plants purchased at a garden center last year and they were very fast growers becoming good-sized bushy plants loaded with flowers until frost killed them. These seedlings started from seed are a poor comparison to last year's plants. I'm hoping these seedlings start to take off but here it is mid-July and so far they've been a disappointment.

Great variety

All orders arrive when expected. All are packaged well. I love their offers. I am always challenged to try new vegetables and new flowers. The descriptions on their internet site are thorough and very useful. Since I live in the humid desert next to the Sea of Cortez, I'm always happy to learn whether something will do well in this environment. I have been a customer for at least 30 years and have never ever had a problem or been disappointed.

Lobularia is the botanical name for Sweet Alyssum
Lobularia Germination Information

Lobularia Seed Germination How to Sow Lobularia:
  • Best sown indoors 4-6 weeks before last frost at a temperature of 65 to 70°
  • Provide NO cover as light aids in germination
  • Expect germination in 8-15 days
  • If sown outdoors, do so in early spring directly where the plants are to grow
  • If sowing seed outdoors, we recommend a maximum planting depth of 4X the width of the seed

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

Spacing: Space 5-8 inches apart in full sun and average, well-drained garden soil

Soil: Sweet Alyssum can also be grown in gravel walkways, edges of gravel drives, or to fill paving cracks where it likes it moist

Temperature: Plant is tolerant of drought and heat. In the deep South, Sweet Alyssum is grown outdoors in the winter as it prefers 55-60° days and 50-55° nights

Additional Care:  Indoors, be sure to provide full sun, good air circulation, cool nights (50-55°), and to keep the soil evenly moist. Shear plants occasionally to encourage repeat flower production

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.

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.
