Polemonium boreale, the northern Jacob's-ladder or boreal Jacobs-ladder, is a plant native to most of the high arctic. In Greenland it is found only in a small area on the east coast, and overall is a rare plant.
The Northern Boreal Jacob's Ladder has a compact growth habit, reaching just 30cm, 12" tall.
Attractive ferny foliage is topped with abundant blue flowers. The arrangement of the leaves on the stems look like ladders. These plants will reblooms the same season if the first spent flowers are removed.
Type: Hardy perennial
Height: 30cm, 12"
Location: Sun or part shade
Hardiness zones: 3-8
Seeds per packet: 20
Sow just under the surface of the soil and water in. Temperature 20-22 C (68-72 F) for 4 weeks. They may be growing at this point. If they have not germinated after 4 weeks then a cooling period is required. Cover them with plastic and place in a fridge for 4 weeks. Be sure they stay moist. After the stratification period they are then brought back to room temperature for them to germinate. Germination can be 30-60 days after the warming period, though some can take longer.

I got these pretty quickly and in perfect order. I can't wait to see what they look like once I plant them. I have another colour and they were so pretty I had to try these. I have used this seller a few times now with great success, and will again. Everything I have ordered has been of good quality!

We placed our order on Thursday and received it on Monday. Here in Canada the tracking link is accurate. Ferri seeds tells you when they're shipping and when your order is delivered, the seeds arriving in excellent condition. We will definitely be ordering again this spring. Keep up the good work!

I happened across Ferri Seeds website when I Googled a particular plant I’d been looking for. I was impressed by their selection of all types of seeds and their good product descriptions along with detailed germination instructions. I found the site and ordered on a Saturday. On Sunday I got a notice that my order had been shipped! The seeds were in my P.O. box on Friday. Such amazing service. It’s too early to comment on germination rates — I’ve just started the stratification process today.

Ferri Seeds offered a hard to find seed on their website. I placed the order but had questions about product and delivery. Customer service contacted me right away. My questions were answered right away. I was kept updated on delivery progress. The seeds were exactly what I wanted. My husband is a very serious gardener. I will do more business with Ferri.
