This Corydalis is an impressive, clump-forming perennial that grows strong and quickly, forming a lush clump of ferny leaves, topped with tropical-looking spikes of flowers! This plant is fully hardy, and easy to grow, sure to impress. Probably the largest Corydalis available. Plants form bulbs.
Type: Hardy perennial
Height: 24-36"
Location: Full sun or part shade
Hardiness zones: 5-9
Seeds per packet: 10
Sow just under the surface of the soil and water in. Leave them at room temperature for 6 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 (15-18C, 59-68F) for them to germinate. Germination can be erratic, generally 30-90 days after the warming period for most seeds, 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!

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.
