A very rare Ironweed, Vernonia lettermannii, or the narrowleaf ironweed, is a plant species native from Arkansas to Oklahoma, though will grow in much of North America. It is a perennial up to 60 cm (24 in) tall. It produces numerous bright purple-violet flowers, arranged in dense clusters. Drought tolerant/ for xeriscaping/ waterwise design, and suitable for natural landscaping. Provides a food source for butterflies and other pollinators. Remarkable perennial for modern garden design. Deer resistant. Abundant and long lasting flowering.
Type: Hardy perennial
Hardiness zones: 4-9
Height: 60cm, 24"
Seeds per packet: 6
Surface sow as light aids germination. Water the seeds in. Leave them at room temperature for 5 weeks. This helps break the phytohormones which inhibit germination. They will not grow yet. Then a cooling period is required. Cover them with plastic and place in a fridge for 80 days. Be sure they stay moist. After the cold stratification period they are then brought back to a cool room (15C, 59F) for them to germinate. Germination is generally 30-90 days after the warming period, though some can take longer.
Ornamental use only. These seeds and/or plants are poisonous.

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!

Never grew coleus from seed, and it was surprisingly easy. They germinated quickly on my heat mat and grow lights. Can't wait to see them in the garden!

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!

Ferri Seeds – one of the best online and most helpful businesses I have ever had dealings with. Quick turnaround, dispatch, and beautifully packaged seeds. What more could you want – beautiful flowers would be nice. Well I am sure they will turn out to be.

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.
