Kevin R. from TX wrote (February 15, 2015):
I bought these because I have never seen them before. I got 50 seeds last year and direct sowed them in loamy soil. 3 to 5 days breaking ground. Grows very fast. The plants topped out 6 to 6-1/2' in 6 to 8 weeks. The flowers a "B-E-A uitful". The really cool thing about this Sun Flower is; if you head it, it makes new flowers. They are a bit smaller. I was able to keep them full of flowers and bee's for 5 months. This year I am going to use them for a natural fence. I forgot to say they are about 4' wide. The first 36 are in the Bio Dome, Along with Black eyed suzy blush vines, and Fox glove. I will set 36 more after I set out the first 36. Winter is over here on the Texas Coast. Top Pick for sure.
Helianthus is the botanical name for Sunflower
Helianthus Germination Information

Helianthus Seed Germination How to Sow Helianthus:

  • Sow 2-3 weeks before planting out
  • Expect germination in 5-10 days
  • They can be sown outdoors after last frost, but remember: they are a favorite food of birds and rodents and may be eaten by them
  • When sowing seed outdoors, we recommend a maximum planting depth of 4X the width of the seed

Superior Germination Through Superior Science

Park's Superior Seeds Park Seed's humidity- and temperature-controlled seed storage vault Park Seed offers some of the highest-quality vegetable and flower seeds available in the industry, and there are a number of reasons for this.

First of all, we have humidity- and temperature-controlled storage, and we never treat any of our seeds with chemicals or pesticides. Nor do we ever sell GMO's (genetically modified seeds), so you always know the products you're buying from us are natural as well as safe for you and the environment.

Superior Standards - University Inspected

Testing seeds against minimum germination standards To make sure we are providing the best seed product possible and that our customers will get the highest number of seedlings from every packet, we conduct our own germination testing and have quality-control measures in every stage of our seed-handling operation. We hold ourselves to standards that are at or above federal and state standards, including testing specific crops more frequently than recommended by federal guidelines. And in order to maintain our organic certification, we welcome Clemson University to inspect us annually to make sure our organic seeds, which are stored and processed separately, are being handled properly.

Hand Packed By Experienced Technicians

Park Seed has been handling and packing vegetable and flower seeds for 145 years, a history that has given us a great understanding of how each variety should be cared for and maintained throughout every step of theprocess, from collection to shipping.

When packing our seeds, the majority are actually done by hand (with extreme care!), and we often over-pack them, so you're receiving more than the stated quantity.

The Park Seed Gold Standard

Park Seed's exclusive Fresh-Pak gold foil seed packets And many of our seeds are packed in our exclusive Fresh-Pak gold foil packets, which are lined to keep moisture out, so the seeds stay fresher for longer. We carefully pack very tiny or fragile seeds in crush-proof vials to ensure safe delivery to your home. Some of the small seeds are also offered as "pellets" (have a clay coating) to make sowing and growing easier.

When it comes to the kinds of seeds we offer, we are constantly seeking something new and provide many unique and hard-to-find varieties from all around the world. Our on-staff horticulturists are ready and available to share their expertise to help you with the success of these seeds, so you can grow a beautiful and productive garden!
