Swiss Chard

This packet contains Bright Lights rainbow variety Swiss chard.


This packet contains sunflowers, giant variety ranging from 6-12 feet.


Planting instructions: Direct sow in spring after the last frost. Sow seeds shallowly or cover lightly, as light is required for germination. Can grow somewhat thickly, or thin to 6-12" apart. Also good in containers.


Depth: 1/4”  Sun: full  Spacing: 6-12”  Sprout:7-21 days  Temp: 50-70°F


Planting tip: Before planting, it is essential to prepare the soil. Shiso plants prefer loamy soil that is rich in organic matter. To improve the soil’s fertility, incorporate compost. This will provide essential nutrients and help retain moisture. Ensure that the soil has good drainage. Shiso is a member of the mint family. Its leaves have the tangy flavor of cumin, mint, nutmeg, and anise combined. Green shiso can be added to salads and is used in wrapped sushi or chopped into hot and cold noodle dishes. Red shiso is more bitter-flavored and can be used in cooked dishes and pickling.

Swiss Chard

Planting instructions: Direct sow seeds 1/2" deep, 4- 6” in rows 12–18" apart or in containers. For continual harvests, cut 2 inches above the soil line or cut stalks as needed.


Depth: 1/2”  Sun: Full Spacing: 4-8”  Sprout: 5-14 days Temp: 41-90°F


Planting tip: Swiss chard will tolerate partial shade, but it does best in full sun. Roughly four to six hours of direct sunlight on most days is ideal. Keep the soil evenly moist but not soggy. A layer of mulch around the plants can help to retain soil moisture. While Swiss chard is commonly considered a cooking green, young chard is also very delicious when eaten fresh. To enjoy your harvest, you can chop it up in salad or lightly cook it as a wonderful side dish. Chard also makes a hearty replacement for spinach, and the stems can be grilled or roasted in place of asparagus. 


Planting Instructions: Direct sow ½” deep when soil temps reach 70 degrees. You can sow until the end of July. 50-60 days until maturity. Succession sow for different bloom times

Depth: ½”  Sun: full Spacing: 4-6”  Sprout: 7-14 days  Temp:70-90°F

Planting tip: If you’re looking to add some diversity to your garden while still reaping the benefits of sunflowers, consider planting sunflower companion plants. These plants can not only enhance the aesthetics of your garden but also improve the overall health of your sunflowers. Try planting Marigolds, Zinnias, Cosmos and Nasturtiums. By planting sunflower companion plants, you can increase biodiversity and encourage beneficial insects and microorganisms to thrive. Vegetable companion plants include corn, beans, cucumbers and squash. Sunflower Seed Salsa Verde Recipe
