Planting Details
| Seed Depth | Press into surface |
|---|---|
| Seed Spacing | A group of 3 seeds every 24"–36" |
| Thinning | When 3" tall, thin to 1 every 24"–36" |
| Germination | 10–14 days |
| Start Indoors | 6 to 8 weeks before your average last frost date. Roots are sensitive to disturbance; sow in biodegradable pots that can be planted in the ground. |
| Direct Sow | RECOMMENDED. 1 to 2 weeks after your average last frost date, or 2 months before your average first fall frost date. |
| Growing & Harvesting | For longest-lasting cut flowers, harvest when 1/3 of the flowers on the stem have opened. Harvest in the morning; cut stem at an angle and immediately place in a bucket of warm water. Before placing in a vase, dip the stem end in boiling water for a minute, or sear it over a flame for 20 seconds; this will stop the flow of the milky sap so it does not clog the stem. |

I used two of these packets this year. The first one had decent germination the second one had basically none. Very disappointing.

I did everything right and did not get one seedling. I am in disbelief. I had better luck last year with a different company, a few seedlings. that is better than none.

- Valerie W.Verified ReviewerRated 4 out of 5 stars2/11/26Keeps on giving
I only had 4 plants grow from the package and of those only two ended up flowering but they did so well I was able to harvest seeds to try again and to even share with friends! It was worth the buy. My plants dis even better the next year!
I am in the low desert of Az and the plants that did the best were planted along a north-facing wall.

What a fantastic review! We're absolutely thrilled to hear that you got several plants from your packet of Outhouse Hollyhock Seeds - that's exactly the kind of success we love to see!
Your experience with multiple plants from one packet really shows what great value these seeds can provide! Hollyhocks are such wonderful performers when they germinate well, and it sounds like yours are off to a perfect start. There's something so satisfying about getting that great germination rate and knowing you'll have multiple beautiful plants to enjoy.
We love that you chose Outhouse Hollyhocks for your garden! These are such charming, cottage garden classics that really bring that old-fashioned beauty and height to any landscape. Once they get established, they're going to reward you with those gorgeous tall spikes covered in beautiful blooms that create such wonderful vertical interest in the garden.
Your success with getting several plants means you'll have an amazing display once they mature - hollyhocks look absolutely stunning when you have multiple plants creating that classic cottage garden look together!
Thank you so much for sharing such a positive experience with the germination success!
