Vernonia gigantea, also known as giant ironweed, or tall ironweed, is s native to the United States and Canada. The plants are up to 2.1 metres, 7' tall. The flowers open over a long period from summer to late fall, and are deep-purple in colour. They are excellent for providing a focal point at the back of the garden, and also for naturalizing meadows and open woodlands. Ironweed are very attractive to many pollinators!
Type: Hardy perennial
Hardiness zones: 5-9
Height: 5', 150cm
Sow just under the surface of the soil and water in. Then cover them with plastic and place in a fridge for 90 days. Be sure they stay moist. After the cold stratification they are then brought back to room temperature 20-22°C (68-72°F) for them to germinate. Germination is irregular over a long period of time, generally 60-90 days, but some can take longer. Do not discard the planting tray, as patience is needed, and they are well worth the wait.

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 had made an error with the adress and upon getting the order back from the post they contacted me and even agreed to send it to a new address without extra charges.
Honestly this kind of service is rare these days.
Thank you to the team of Ferri Seeds, rest assured I will be purchasing from this vendor again.

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.
