More sugar and less fiber than its green cousins!
600 days (approximately 2 years) to reach maturity.

Don't let the long growth time of this perennial vegetable discourage you; Sweet Purple Asparagus will produce heavily and dependably for up to 15 seasons! This is a vegetable for your permanent garden, asking only well-drained fertile soil receiving sunshine and water. Begin this gourmet (and exceptionally healthful) crop today, and enjoy the results for more than a decade to come!

Purple asparagus has actually been around a long, long time; records exist of it being grown in France more than 150 years ago, and it was not new then. But it has only recently arrived on American tables, and we are proud to make the seed available to Park gardeners this season. Its benefits go well beyond its striking color and beauty!

Sweet Purple spears are about 6 to 9 inches long, much larger than traditional green types and also thicker. Best of all, they are stringless and tender, with less fiber than their green cousins, so they can be eaten from tip to base -- no need to snap off the tough end! Boasting 20% more sugar than green asparagus, they are mild, nutty, and sweet.

But concealed within each yummy bite is a good serving of anthocyanin, a powerful antioxidant that helps fight cancer. This asparagus is a superfood, absolutely central to a nutritious disease-prevention diet.

Sweet Purple loses much of its beautiful deep burgundy-violet coloration when cooked, but you can minimize this by sprinkling the spears with lemon juice just before cooking, or by lightly steaming. Because this variety is less fibrous, it cooks more quickly than green varieties.

Sweet Purple is a large plant with fern-like foliage reaching 4 to 5 feet high and 12 to 30 inches wide. Let the foliage die down naturally; it feeds the plant as it matures, so you don't want to cut it back until it falls over. That's about all there is to maintaining this vigorous perennial!

Start the seeds indoors in your Bio Dome or in peat pots or other individual containers. The seed germinates well but slowly; sow it 12 to 14 weeks before last scheduled spring frost in your area, and expect 3 weeks to pass before you see the shoots. When it's time to transplant the seedlings, let them harden off in a shaded, protected garden spot for at least 5 days before being set out in the soil.

Enrich the planting site with a balanced fertilizer, and make sure the drainage is good. Raised beds work well for this perennial, but traditional rows are also fine. Bear in mind that this is a tall plant that will shade neighboring plants during the growing season. During the first two years, as the plants reach maturity, make sure they never dry out completely. Cut back the dead foliage in late autumn and keep the bed weeded to prevent insects from sheltering near the plants.

Once your purple asparagus bed is established, you will wonder how you ever got by without fresh, delicious, healthy stalks straight from the garden to your plate! Enjoy. Zones 3-9.

Asparagus Germination Information

Asparagus Seed Germination How to Sow Asparagus:
  • Soak seeds in warm water for 48 hours before sowing
  • Best sown indoors at a temperature of 75-80°, at a depth of 4 times the size of the seeds.
  • Expect germination in 14-21 days.
  • Seeds can be sown outdoors but after all danger of frost is past in the spring and in a warm soil.

How to Grow Asparagus:
Care: Space 3-5 inches apart in full sun.site in a well-prepared,deep, rich, loose, well-limed soil.

Soil: Keep plants well-watered and fertilize them before growth starts in the spring and again after harvest. Fertilize with a top dressing high in nitrogen and potassium, but low in phosphorus.

Transplant: Transplant when there are at least two sets of true leaves

Appearance and Use:

This plant with delicate, ferny foliage grows 3 feet tall and spreads 2-3 feet wide. It is grown for the edible, tender, green or purple-tinged, new shoots that push through the soil in spring. Cut the shoots when they are 6-8 inches tall by snapping them at ground level or cutting them just below the soil surface. Harvest the shoots for about 2 weeks, then leave off to allow the remaining shoots to develop into the tall ferny stems


About Asparagus:
Pronunciation:  as-pãr’å-gus
Lifecycle:  Perennial
Origination: Liliaceae; native to Europe, Asia, and North Africa.

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?

It 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?

Extremely 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.
