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 – 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.

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.
