This kale has it all. Beautiful, ruffled leaves are tasty and have amazing color. Extremely cold tolerant, 'Redbor's' purple color and curliness intensifies, and flavor sweetens as temperatures drop in the fall; plants can last even through hard freezes. Sow with pansies, violas, and snapdragons for long-lasting fall color. Looks great in containers. Seeds may have an inert organic coating.

Redbor Kale Seeds Reviews

Wish I had purchased this variety elsewhere

3 out of 5 stars Sep 4, 2020
Take note of seed quantity- this is expensive seed though I don't understand why. I purchased from BI due to convenience of ordering other seeds from them. Normally happy enough with their products but you can find this particular seed for a better price and much larger quantity elsewhere. The biggest frustration to me was the packaging. It comes in a very small foil lined package that as I unfortunately discovered, isn't the most secure while you're using it. It's hard to tear it open for a clean edge to easily dispense seed so it takes much more fumbling than normal. I carefully set the package down in between planting seeds, and it tipped over. As a result of the package being so small the seeds fell out and I lost 80% of the seeds. So frustrating! I couldn't find and recover them from the grass next to the planting bed! I realize this accident is not Botanical Interests' fault, but if the packaging envelope had been consistent with other seeds from them this would not have happened. Just a fair heads up to others who purchase to be extra careful not to let this disappointing accident happen. I hope I get good germination from the few that I planted! Out the gate I am deducting 2 stars on this one for price and packaging.

It may have been my process or the Heat of Galveston, but none of the seeds germinated
Douglas G Stark from TX
Owner Response: Hi Douglas, Thank you for sharing your experience. Similar to the kohlrabi you reviewed the soil temperature needs to be 65-85 degrees F for kohlrabi to germinate, meaning above 85 degrees F you will not be able to achieve good germination. A soil thermometer may be helpful as a guide for sowing and we do include soil temperatures on all herb and vegetable seed packets to help gardeners get the best germination. Also, in your high-heat area in order to keep seeds consistently moist, you will likely have to water multiple times a day. We hope that is helpful. A customer service agent will contact you to help you further troubleshoot the issue.

Loved growing this kale - beautiful plants, fewer cabbage worms

5 out of 5 stars Dec 30, 2020
Strong plants, very tall, lovely color, turned a beautiful true purple as the weather got colder. I read somewhere that cabbage worms don't eat purple kale - not 100% true. But my dinosaur kale was decimated and the Redbor had only a few worms. Will grow again.

Most beautiful plant

5 out of 5 stars Jan 27, 2021
I am writing this review because the plant is so beautiful. The ultimate edible ornamental. The red color is so intriguing and when it ends up on the dinner table, everyone remarks of the deep crimson color. One of my all time favorite kale ever.

didn't grow

1 out of 5 stars Feb 28, 2021
I was excited about this kale but the plants didn't grow beyond two inches. My other kale (baby) is prolific, along with my other varieties. These seeds just failed.
Elizabeth from CA
Owner Response: Hi Elizabeth, We are sorry you had issues growing this kale. We are always happy to help troubleshoot growing issues. Once a seed germinates its success is dependant upon its growing condition as it uses those conditions to photosynthesize and make its own food. For instance, similar to a goldfish, in a small container plants will be stunted, or in the absence of nutrients, plants will also be stunted. Please don't hesitate to contact us for help. Happy gardening!

Beautiful Bounty!

5 out of 5 stars Mar 15, 2022
Next to your Georgia Collards, this by far has been a beautiful bounty! It flourishes in AeroGardens and cooks like a dream. Very tender and extremely delicious. Had no problems with growth, in fact it pops its head up at around 3-5 days. I would highly recommend this to my hydroponic gurus out here. A plant that would be a great starter for newbies to hydro growing.
