Its wavy blue-gray leaves add color to an all-season garden while its fragrant blossoms attracts pollinators (and our trial gardener!) throughout the summer.

Top notch

Pinetree was a pleasure to do business with. My first order had some issues...as soon as I let them know pinetree stepped up and made it right. You can't ask for more than that. I highly recommend them...I know I'll be ordering again soon. My sea kale is still growing.

Rare seed

Had 5 of 13 seeds germinate after removing outer seed casing using a heat mat and grow lights which is pretty good for a non commercial variety. They seemed to be very sensitive to overheating under glass in a cold frame and three died. The other two look fine in the ground even on the hottest days. Taste is kind of unique, definitely not like kale and somewhat similar to cabbage. Only time will tell if they spread and produce enough to be worthwhile but so far they have passed the biggest test because the slugs, snails and aphids which plague brassicas here have not shown any interest. Will be buying more seed, can't find it anywhere else!

Hard to germinate seeds, but worth the effort for edible landscaping

I've been wanting to grow sea kale for several years now because it's a tough perennial vegetable, but also quite ornamental with flowers that attract pollinators. I was excited to see the seeds as a new product from Pinetree Garden this year. However, I knew from the instructions on the packet that germination would be challenging, even after removing the outer shells on the seeds. The only method that gave me any germination (at about 50%) was planting the seeds in moist potting medium and leaving in an unheated garage starting in March (about two months before my last frost date), and then moving outdoors in mid-April. I now have a few healthy seedlings. In theory, if I can get even one mature plant established it will then be possible to propagate by dividing off side shoots each spring. My overall take is that these seeds are for the gardener who is willing to put in the extra effort to establish an unusual edible landscaping plant.

Spring seeding

I am starting the Salsify I bought from you. Doing well. Last night I took the husk off my Sea Kalr seeds and will be plantings then out and seeding them under glass in several environments over the next month. Great hun.
