Petrocallis pyrenaica
PYRENEAN WHITLOW GRASS
SKU: 1601-010
Regular price
- Unit price
- / per
A rarely-offered alpine plant native to the Pyrenees, Alps and Carpathians, found in limestone screes and rocks. Densely tufted and often cushion-forming. The leaves form rosettes, 4-6mm long. The flowers are four-petalled, 5-8mm across, pale pink or lilac. An ideal rock garden plant!
Very limited supply.
Type: Hardy perennial
Hardiness zones: 3-8
Location: Sun or part sun
Seeds per packet: 10 (previously 5)
Surface sow as light aids germination. Water the seeds in. Cover them with clear plastic and place in a fridge for 60 days. Be sure they stay moist. After the cold stratification period they are then brought to 20-22°C (68-72°F) to germinate. Keep in a bright location, out of direct sun, until germination begins. Germination is generally 30-90 days after the warming period, though some can take longer, and will germinate irregularly over a long period of time. Do not discard the planting tray, as patience is needed, and they are well worth the wait.

I'm on my third order. I'm really happy. My first seedlings have already come out and some have even been transplanted into larger pots. There are even plants that I had difficulty finding, and I found them on your site. A big thank you to you! And surely a future order in 2026

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!

I was apparently one of their first international customers. The seeds were well packed and labeled. The seeds also arrived quite fast to my country. Terry, was a very great help.
I waited this long to post since I had only recently planted my seeds and they successfully germinated.
Also wanted to add that this seller is one of the only ones selling legitimate cymbopogon nardus(the actual citronella plant) seeds.

I am very pleased with the seed I have recieved and have increased my order this year. The selection is vast and I have been able to find many on my special wish list. The service is fast and friendly. Queries are answered quickly. I highly recommend this source for seed.

I spent about a month designing my border and cottage gardens while it was raining and snowing. I made a list of the flowers and now I started to shop for my seeds. I went to all the usual seed retailers and could not get much of what I wanted. I thought I was going to have to shop online in the USA which is against my principles in this environment we find ourselves. THEN I FOUND YOU! Thank you for being there for me on two fronts: I fully completed my list and I shopped Canadian. It's been a really good day. Thank you

The pictures and reviews caught my attention and thus my order. I also am determined to buy Canadian and after seeing that you ship from Toronto sealed the deal. Buy locally, provincially or nationally will be my modus operandi for the foreseeable future

I ordered several seeds packets from Ferri Seeds and they all arrived in a safe little box, with each type in a plastic baggie or glossy paper pouch. The seeds were good quality and some have already germinated! I had a question as a follow up and they responded over the weekend! Would buy from them again in the future.

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!

I have a “wild “ garden , and love to bring in grasses and flowers with the unique shapes and subtle colours I see in nature. My plant references are often gardens in the UK and Europe where there is a tremendous diversity of plants available, that were previously not accessible in Canada. Thank- you so much, Ferri Seeds , for opening up my garden world .

I was looking for a local, reputable company to buy seeds from and was very pleasantly surprised at their selection and pricing. I found more on this site than I could on bigger name brands. I'm very pleased to be able to have gotten exactly what I wanted and not have to compromise with a bigger company. Will definitely be purchasing again, especially love the more rare varieties offered.

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!

My order, made late afternoon, April 27th, and needed in a bit of a rush, was mailed next morning and arrived in my rural mailbox in BC, May 5th.
Thank you for your cheerful, friendly emails and prompt service. I certainly recommend you others and will be sure to keep an eye on the range of seeds you offer in future.

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.

I ordered seeds and noticed after submitting that my postal code was incorrect, my fault. I contacted Ferri and was responded to right away even though they had no power. They thanked me for my understanding, as they had indicated there may be a delay. I got the seeds within 5 business days, very well packaged with detailed instructions on the back. So happy, can't wait to see results. Also happy it is Canadian!
