Growing straw flower plants (Helichrysum bracteatum) is a rewarding way to add bold color and texture to your garden. With proper care, these drought-tolerant beauties bloom all summer and make stunning dried flowers.
If you’re looking for a flower that brings bold color, long-lasting beauty, and minimal fuss to your garden, the straw flower plant might just be your new favorite. Known scientifically as *Helichrysum bracteatum*, straw flowers are cheerful, daisy-like blooms that come in vibrant shades of yellow, orange, red, pink, and white. What makes them truly special is their papery, straw-like texture—hence the name—and their incredible ability to hold their color and shape long after being cut.
Straw flowers are not only eye-catching in garden beds and borders, but they’re also a top choice for dried flower arrangements. Whether you’re a seasoned gardener or just starting out, these resilient annuals are easy to grow and incredibly rewarding. They bloom from midsummer through fall, offering months of color with very little effort. Plus, their upright growth habit and sturdy stems make them excellent cut flowers for bouquets that last weeks in a vase—or even years when dried.

Why Choose Straw Flower Plants?
Straw flowers have been a garden favorite for decades, and it’s easy to see why. Their bright, cheerful blooms light up any space, and their unique texture adds visual interest that many other flowers lack. Unlike delicate blossoms that wilt quickly, straw flowers are built to last. Their bracts—modified leaves that look like petals—are naturally dry and papery, which gives them that signature “straw” appearance.
One of the biggest advantages of growing straw flower plants is their versatility. They work beautifully in cottage gardens, wildflower meadows, container gardens, and even as part of a pollinator-friendly landscape. Bees and butterflies are drawn to their nectar-rich centers, making them a great addition to eco-conscious gardens. And because they’re annuals, you can experiment with different colors and varieties each year without long-term commitment.
Perfect for Drying and Crafting
One of the most beloved traits of straw flowers is their ability to dry beautifully. Unlike many flowers that fade or lose their shape when dried, straw flowers maintain their vibrant colors and sturdy form. This makes them ideal for dried bouquets, wreaths, potpourri, and floral crafts. Simply cut the stems when the flowers are fully open, tie them in small bunches, and hang them upside down in a cool, dry, dark place for 2–3 weeks. Once dried, they can last for years with minimal fading.
How to Grow Straw Flower Plants
Growing straw flowers is straightforward, whether you start from seeds or purchase young plants from a nursery. These plants are native to Australia but adapt well to a variety of climates, especially in USDA hardiness zones 8–11. However, since they’re typically grown as annuals, they can be planted almost anywhere during the warm growing season.
Starting from Seeds
If you’re starting from seeds, begin indoors about 6–8 weeks before your last expected frost date. Straw flower seeds need light to germinate, so sprinkle them on top of a seed-starting mix and lightly press them in—don’t cover them with soil. Keep the soil moist but not soggy, and place the tray in a warm spot (around 70°F) with bright, indirect light. Germination usually takes 7–14 days.
Once seedlings have developed two sets of true leaves and the outdoor temperature stays above 60°F at night, it’s time to harden them off. This means gradually exposing them to outdoor conditions over 7–10 days to reduce transplant shock. After hardening, transplant them into the garden or containers, spacing them 12–18 inches apart to allow for airflow and growth.
Planting in the Garden or Containers
Choose a sunny spot with well-draining soil. Straw flowers hate wet feet, so avoid heavy clay soils unless you amend them with compost or sand. If planting in containers, use a high-quality potting mix and ensure the pots have drainage holes. A mix designed for succulents or cacti works especially well.
When planting, dig a hole slightly larger than the root ball, place the plant in, and backfill with soil. Water thoroughly after planting to help the roots settle. For container gardens, you can mix straw flowers with other sun-loving plants like marigolds, zinnias, or lavender for a colorful, low-maintenance display.
Straw Flower Plant Care Tips
Once your straw flowers are in the ground, they require minimal care—but a few key practices will keep them looking their best all season long.
Sunlight Requirements
Straw flowers are sun worshippers. They need a minimum of 6–8 hours of direct sunlight each day to produce strong stems and abundant blooms. In hotter climates, they can tolerate some afternoon shade, but too much shade will result in leggy growth and fewer flowers. If you’re growing them in containers, place them on a sunny patio, balcony, or windowsill.
Watering Guidelines
While straw flowers are drought-tolerant once established, they do need consistent moisture during their first few weeks after planting. Water deeply once or twice a week, allowing the soil to dry out slightly between waterings. Overwatering is one of the most common mistakes—soggy soil can lead to root rot, especially in poorly draining areas.
A good rule of thumb: if the top inch of soil feels dry, it’s time to water. In hot, dry weather, you may need to water more frequently, but always check the soil first. Mulching around the base of the plants can help retain moisture and keep roots cool.
Soil and Fertilizing
Straw flowers aren’t picky about soil pH, but they do best in slightly acidic to neutral soil (pH 6.0–7.0). The most important factor is drainage. If your soil is heavy or clay-like, mix in compost, perlite, or coarse sand to improve aeration and water flow.
Fertilizing isn’t strictly necessary, but a light application of a balanced, slow-release fertilizer at planting time can give your plants a boost. Avoid high-nitrogen fertilizers, as they promote leafy growth at the expense of flowers. If your plants look pale or stunted, a diluted liquid fertilizer every 4–6 weeks can help.
Deadheading and Pruning
To encourage continuous blooming, deadhead spent flowers regularly. Simply pinch or snip off the faded blooms just above a set of leaves or a new bud. This prevents the plant from putting energy into seed production and redirects it toward forming new flowers.
As the season progresses, you may notice some lower leaves turning yellow or stems becoming leggy. Light pruning can help maintain a tidy shape and improve airflow, reducing the risk of fungal diseases. Trim back any weak or overcrowded stems to promote bushier growth.
Pest and Disease Management
One of the best things about straw flower plants is their resistance to pests and diseases. They’re rarely bothered by aphids, spider mites, or other common garden insects. Their dry, papery bracts and strong scent seem to deter most critters.
However, in humid or overly wet conditions, they can be susceptible to fungal issues like powdery mildew or root rot. To prevent this, avoid overhead watering, space plants properly for good air circulation, and remove any diseased foliage promptly. If you notice a white, powdery coating on the leaves, treat it early with a fungicidal spray or a homemade solution of baking soda and water.
Slugs and snails may occasionally nibble on young seedlings, especially in damp weather. Use organic deterrents like diatomaceous earth or copper tape around plant bases to keep them at bay.
Harvesting and Drying Straw Flowers
One of the most rewarding aspects of growing straw flowers is harvesting them for long-lasting arrangements. The best time to cut straw flowers is when the blooms are fully open but still fresh—usually in the morning after the dew has dried.
How to Cut and Dry
Use clean, sharp scissors or pruning shears to cut stems at an angle, leaving at least 6–8 inches of stem. Remove any leaves that will fall below the water line if you’re making a fresh bouquet. For drying, strip off all leaves and tie the stems in small bunches with string or rubber bands.
Hang the bunches upside down in a warm, dry, dark place with good airflow—like a garage, attic, or closet. Avoid direct sunlight, as it can fade the colors. After 2–3 weeks, the flowers should be completely dry and ready to use. Store them in a cool, dry place away from light to preserve their vibrancy.
Creative Uses for Dried Straw Flowers
Dried straw flowers are incredibly versatile. Use them in everlasting bouquets, wreaths, or swags. They’re also popular in wedding decor, holiday arrangements, and home fragrance projects like potpourri sachets. Their bright colors and sturdy texture make them stand out in any craft project.
Popular Varieties of Straw Flowers
There are many cultivars of straw flowers to choose from, each offering unique colors and growth habits. Some popular varieties include:
- Bikini Series: Compact plants with large, double blooms in bright shades like orange, yellow, and red. Great for containers and borders.
