Cortaderia Selloana, commonly known as Pampas Grass, is a flowering plant native to southern South America, including the Pampas region after which it is named. There are around 25 species in the genus Cortaderia.
Cortaderia is an evergreen Perennial growing up to 12 feet tall at a fast rate. Flowering occurs primarily in late summer.
Plants are fully grown, from seed germination to maturity, in 2-4 years.
Pampas grass is a drought-tolerant ornamental that flourishes in sunny locations with minimal maintenance once established.
The center stems of pampas grass will die after one growing season, but new shoots of leaves arise from the edge of the plant to increase its size.
The life span of pampas grass is 10-15 years.
Light Preferences: Full sun
Water: Dry to medium (but keep the soil moist in the first growing season).
Maintenance: Medium
HOW TO GROW PAMPAS GRASS FROM SEEDS
- Pour an even mixture of moistened peat moss and light sand into a 4-inch diameter planting container. Pink pampas grass seeds require loose, well-drained, moist soil for germination. Plant the seeds indoors four to six weeks before the last frost in spring. Keep the plants indoors during the first winter to protect young plants from frost if seeds are planted later than Spring.
- Place five evenly spaced pink pampas grass seeds on the soil surface in the planter. Lightly press the seeds into the soil; do not cover them with potting mix.
- Water the soil until moist to the touch, but not soaking wet. Add water slowly so the seeds don't wash away.
- Cover the planters with a clear plastic food storage bag. Place the open end of the bag over the planter to allow air circulation and control soil temperature and moisture. Alternatively, you can push straws into the soil around the perimeter of the planter and use them to support clear plastic wrap.
- Make sure the pot receives six to eight hours of direct or filtered sunlight daily. The room temperature should be between 65 to 75 degrees Fahrenheit for best germination success. You can place the planters on a seed germination mat, on top of a radiator or near a vent to provide additional heat in cooler rooms.
- Mist the seeds daily to maintain an even level of moisture in the soil required for seed germination. Keep the soil moist to the not wet. Excessive moisture can rot seeds and seedlings.
- Allow one to two weeks for the pink pampas seeds to germinate and reveal seedlings. If each of the five seeds germinate, leave all the plants in place to grow as a single bunch.
- Transplant the pink pampas grass outdoors when plants reach a height of 3 to 4 inches. Plant the grass in holes twice the diameter of the original container, or 8 inches in diameter, and the same height as the pots. Space each plant 8 feet apart to allow the pink pampas to reach maturity. Select a site with full to partial sunlight.
- Spread a 2- to 3-inch layer of shredded bark mulch around the pampas grass clumps to aid in moisture retention and help prevent weeds. Do not push the mulch directly against the stems.
- Water the plants regularly to keep the soil moist for the first growing season. As plants mature, they should require irrigation only once weekly (more often during hot, dry months).
- Fertilize the pampas grass plants with a complete fertilizer, such as 10-10-10, four times a year at a rate of 2 pounds of actual nitrogen per 100 square feet. Broadcast the granular fertilizer evenly around the plants; do not put the fertilizer directly against the plant material. Always water thoroughly after fertilizing to protect the plant's tender roots from the fertilizer salts.
- NOTE: It may take two to three years after sowing seeds until plants produce pink plumes.

FAQs Seed Planting
FAQs Seed Planting
We want every seed you plant to thrive. Below you'll find answers to the most common questions from our customers — from choosing the right seeds to getting them in the ground and storing extras for next season.
🌱 Germination & Sprouting
What is a germination rate, and what should I expect?
Germination rate is the percentage of seeds expected to sprout under ideal conditions. Our seeds are tested and carry high germination rates, typically 85–95%+. You'll find the specific rate listed on each product page.
Why aren't my seeds sprouting?
The most common problems are:
- Temperature: Most seeds need soil temperatures of 65–75°F to germinate. Cold soil slows or prevents sprouting.
- Moisture: Soil should be consistently moist — not waterlogged and not bone-dry.
- Depth: Planting too deep is a frequent mistake. See planting depth guidance below.
- Seed age: Old or improperly stored seeds lose viability over time.
If seeds haven't sprouted within the expected window (listed on each product page), please reach out — our Seed Warranty has you covered.
How long does germination take?
It varies by plant type. Fast germinators like Cosmos, Zinnias, Marigold sprout in 5–7 days. Slower varieties like Lavender, Columbine, Larkspur, lupine can take 14–21 days or more. Always check the seed packet or product page for the expected germination window.
🌿 Planting Instructions
How deep should I plant my seeds?
A general rule of thumb is to plant seeds at a depth of 2–3 times their diameter. Tiny seeds (like Aubrieta, Astilbe, Begonia) are often just pressed onto the soil surface. Larger seeds (like Sunflower, Morning Glory or Nasturtium) go approximately 1 inch deep. Specific depth instructions are printed on each seed packet and listed on the product page.
How far apart should I space my seeds?
Spacing depends on the mature size of the plant. Overcrowding leads to competition for nutrients and poor airflow. Product pages list the recommended spacing, and we always suggest thinning seedlings to the strongest plant once they've established.
How much light do my seeds need?
Light requirements vary by variety:
- Full sun: 6+ hours of direct sunlight daily (tomatoes, peppers, sunflowers, petunias, marigold, zinnia, portulaca.)
- Part shade: 3–6 hours (begonias, astilbe, columbine, foxglove, some herbs)
- Full shade: Less than 3 hours (ferns, mint, cilantro)
Each product page includes the light requirement for that specific variety.
Should I start seeds indoors or sow them directly outside?
It depends on the plant and your climate:
1. Starting seed indoors
Flowers to start 6–10 weeks before your last frost date:
2. Direct sow outdoors
Cool-Weather Flowers (Sow in Early Spring or Late Fall)
Warm-Weather Flowers (Sow After Last Frost)
Product pages specify our recommended sowing method for each variety.
📅 Seasonal Timing & Regional Planting
When should I plant my seeds?
Timing depends on your USDA Hardiness Zone and whether you're growing warm-season or cool-season crops:
- Cool-season crops (lettuce, kale, spinach, peas): Plant in early spring or fall, 4–6 weeks before your last/first frost.
- Warm-season crops (tomatoes, basil, squash, beans): Plant after your last frost date when soil has warmed.
Not sure of your zone? Visit the USDA Plant Hardiness Zone Map and enter your zip code.
Can I grow flower seeds year-round indoors?
Many flowers, herbs, microgreens, and leafy greens can be grown indoors year-round with a sunny south-facing window or a grow light. We recommend at least 14–16 hours of artificial light per day for most edible plants grown indoors in low-light seasons.
I'm in a warm climate — do the planting seasons change?
Yes! Gardeners in USDA Zones 9–11 (Southern California, Florida, Gulf Coast) often plant warm-season crops in late winter and cool-season crops in fall through early spring, essentially the reverse of northern growers. Check your local cooperative extension service for region-specific planting calendars.
📦 Seed Storage & Shelf Life
How should I store unused seeds?
Proper storage dramatically extends seed viability. Keep unused seeds:
- In a cool, dark, and dry location (a sealed container in the refrigerator is ideal)
- Away from humidity — moisture is the enemy of seed viability
- In labeled envelopes or airtight containers with silica gel packets to absorb moisture
How long do seeds stay viable?
Shelf life varies by type. Here are general guidelines.
1–2 Years Flower Seeds Viability:
Delphinium, Asters, Delphinium, Phlox, Larkspur
3–4 Years Popular Flower Seeds Viability:
5–6 Years Flower Seeds Viability:
Seeds stored correctly often remain viable beyond these estimates. Do a quick germination test: place 10 seeds on a damp paper towel, seal in a bag, and check after the expected germination window. If fewer than 5 sprout, it's time for fresh seeds.
Do seeds expire?
Seeds don't have a hard expiration date, but viability gradually decreases over time. Our seeds are packed for the current season with high germination rates. For best results, use seeds within their recommended shelf life window and store them properly between uses.
🚚 Shipping & Seed Handling
Are seeds safe to ship? Will the heat or cold damage them?
Seeds are remarkably resilient in transit. Unlike live plants, seeds can tolerate a wide range of temperatures during shipping without damage. We package our seeds carefully to protect them from moisture. In extreme heat conditions, we recommend opening your package promptly and storing seeds in a cool location.
How are my seeds packaged?
Seeds are packaged in moisture-resistant seed packets designed to keep them fresh from our facility to your garden. Each packet is clearly labeled with the variety name, planting instructions, germination rate, and seed count.
How long does shipping take?

DISCLAIMER
Seed is a live product which depends on grower skills, such as proper planting time, seed depth, type of soil, irrigation, proper use of fertilizers, weed controls, fungicides, insecticides, disease free soil, and reasonable weather conditions during the growing period. Germination is affected by factors as temperature, moisture content, light intensity and planting method. These factors are totally out of the seller's control and are the buyer's responsibility and risk. The seller cannot unconditionally guarantee seed to perform properly regardless of conditions or the buyer's methods or mistakes.

Germinated very good. Looks like correct seeds. Grow well. I just hope it will bloom as shown on picture. Will add additional feed back later
I started these in tiny pots, putting a pinch of seeds in with some starter seed soil, spray misted everyday or when the soil was dry. Germination was fairly quick (7-10 days).
Only half of the seeds are growing. I will wait a little more.. I'll have to update how many started.
I got 4 inch potting holders the plastic kind and planted them about 1/2 under good potting soil with micreal grow they now are growing like crazy there already 3 inches in height as soon as they get about 7 to 10 inches I will put in ground. I have over 40 pots so ya I will have them in front yard and back yard I am very pleased with this order they are growing great .I would buy from them again if I need to.
They still sprouting. I started them inside and put under some grow lights.
