Hardy & Comes Back
Cold-hardy in USDA zones 3–8 and self-sows, so your garden keeps blooming year after year.
🌈 Grow a Rainbow of Colors
Every packet is a colorful mix. Plant a row and watch soft pinks, fiery reds, sunny yellows and deep velvety burgundy open side by side, all on the same tall, ruffled spires.

- Hot Pink
- Cherry Red
- Apricot
- Sunny Yellow
- Snow White
- Violet
- Burgundy
Colors grow naturally from seed, so every garden gets its own one-of-a-kind mix.
Summer, Stacked Up a Single Stem
Buds open from the bottom up, so each spire keeps flowering for weeks, from June into August.
From Seed to Bloom
Give them sun and leave their roots alone. Here's the whole season at a glance.

Sow
Start indoors 8–10 weeks before your last frost, or sow outdoors once frost has passed. Cover with ¼ in (6 mm) of soil.

Sprout

-
After the last frost
Plant out
Move young plants into full sun, 18–24 in (45–60 cm) apart. Transplant early, as the long taproot dislikes disturbance.

Frequently Asked Questions
Everything you need to know before you sow your double hollyhock seeds.
For the best chance of flowers in the first year, start your seeds indoors in late winter.
Will they flower in the first year?
Hollyhocks are naturally biennial, so the fullest show usually comes in the second summer. Start seeds indoors in late winter and many plants will send up a first-year stem by late summer.
When should I plant the seeds?
Indoors 8–10 weeks before your last frost, or directly outside once frost has passed. You can also sow outdoors in late summer or early autumn for flowers the following year.
Do they need full sun?
They bloom best with 6 or more hours of direct sun a day. In very hot climates, a little afternoon shade is fine.
Can I grow them in pots?
Yes, as long as the pot is at least 12 in (30 cm) deep to make room for the taproot. Container plants stay a little shorter and appreciate a stake.
How much care do they need?
Very little. Water young plants until they're established, then only in long dry spells. Water at the base to keep leaves healthy, and stake tall stems in windy spots.
Will my flowers look exactly like the photos?
Flowers grown from seed vary naturally, so expect some difference in shade and fullness from plant to plant. That mix is part of what makes a hollyhock border so lively.
