At a glance
Strawflowers are highly susceptible to damping off and root rot if the soil stays consistently wet, so good drainage is not optional at any stage of growth.

Step-by-step planting
Strawflower seeds are small and relatively straightforward to start, but results vary depending on your soil temperature, moisture levels, and local climate, so approach the process with attentive care rather than a set-and-forget mindset.
-
1
Choose Your Starting Method
You can direct sow strawflower seeds outdoors after your last frost date or start them indoors 6 to 8 weeks earlier, pressing the seeds lightly onto the surface of moist seed-starting mix without covering them, since they need light to germinate.
-
2
Get the Temperature Right
Aim for a soil temperature of 70 to 75 degrees Fahrenheit for germination, using a heat mat indoors if your space runs cool, since cold soil slows or stalls sprouting significantly.
-
3
Keep Moisture Consistent but Moderate
Mist the surface gently to maintain moisture without waterlogging, checking daily and never letting the mix dry out completely or sit in standing water during the germination window.
-
4
Transplant With Care
Once seedlings have two sets of true leaves and outdoor temperatures are reliably warm, harden them off over 7 to 10 days before transplanting into a full-sun spot with well-draining soil.
-
5
Space for Airflow
Plant out at 9 to 12 inches apart, depending on the variety size, to encourage good airflow around the foliage and reduce the humidity at soil level that invites fungal problems.
-
6
Water and Feed Lightly
Once established, strawflowers are drought-tolerant and actually bloom more freely under lean conditions, so water deeply but infrequently and skip heavy fertilizing, which tends to produce foliage at the expense of flowers.
-
7
Harvest for Drying
For dried arrangements, cut stems when the blooms are about halfway open, because they continue to open after cutting and fully open flowers tend to drop their petals during the drying process.

Frequently asked
Questions about Strawflower Seeds – Xerochrysum bracteatum
Do strawflower seeds need light to germinate?
Yes, Xerochrysum bracteatum seeds require light to germinate, so press them onto the surface of your growing medium rather than burying them. Even a thin layer of soil or vermiculite can reduce germination, so surface sowing is genuinely important here, not just a suggestion. A bright windowsill or a grow light positioned close to the tray will give them what they need.
How long do strawflowers take to bloom from seed?
Under good conditions, strawflowers typically begin blooming around 10 to 12 weeks from sowing, though this varies with temperature, light, and how early in the season you started. Starting indoors 6 to 8 weeks before your last frost date is the most reliable way to get flowers by early summer. Direct-sown plants in warmer climates can also perform well, though they will bloom later in the season.
Can strawflowers be grown in containers?
Strawflowers grow reasonably well in containers as long as the pot is large enough (at least 10 to 12 inches in diameter), has excellent drainage holes, and sits in a spot that receives full sun for most of the day. They are not heavy feeders, but container plants will benefit from occasional light feeding since nutrients wash out with watering. Be especially careful not to overwater, since containers can trap moisture around the roots more than garden beds do.
Are strawflowers deer resistant?
Strawflowers are generally considered deer resistant, likely because of the stiff, papery texture of their foliage and flowers, which deer tend to find unappealing compared to softer plants. That said, no plant is completely immune when deer pressure is high or food is scarce, so if you garden in an area with heavy deer traffic, some protection may still be worthwhile early in the season when plants are young and tender. Established plants seem to be left alone more reliably than seedlings.
How do you dry strawflowers for arrangements?
The key to drying strawflowers well is harvesting at the right stage: cut when the blooms are about half to three-quarters open, not fully open, since they continue to open as they dry and fully open flowers lose petals easily. Strip the lower leaves, bundle four to six stems loosely together, and hang them upside down in a warm, dry, well-ventilated space out of direct sunlight for two to three weeks. The colors hold remarkably well, which is exactly why the everlasting flower earned that name.
Are strawflowers perennial or annual?
In most temperate climates, strawflowers are grown as annuals because they cannot survive frost. In frost-free zones (roughly USDA zones 10 and above), they can persist as short-lived perennials, sometimes returning or self-seeding reliably. For most gardeners, the practical approach is to treat them as a strawflower annual and resow each spring, which is easy enough given how freely they bloom in a single season.
When should I start strawflower seeds indoors?
Count back 6 to 8 weeks from your average last frost date to find your indoor sowing window. For example, if your last frost falls around mid-May, starting seeds in late March gives seedlings enough time to develop without outgrowing their trays before outdoor conditions are ready. Starting too early can lead to leggy, root-bound plants that struggle at transplant time, so resist the urge to rush the season.
