Mountain Lettuce is a herbaceous perennial in the aster family native to rocky, dry areas in central and southern Europe. It has pretty blue-green leaves and dainty blue flowers. It grows about two feet tall, and some plants will likely flower in the their first year.
I found the leaves to taste good all summer, although I planted them on the north side of some tomato plants so they got a bit of shade. They were crunchy, mild, with a slight cucumber flavour and no bitterness. They would make a great salad green! They may become more strong in harsher, dry environments but I haven't tested that yet.
These seeds come from a two breeding lines sent to me from Rhizowen in the UK, so there is some diversity in plant size, leaf shape, etc. The plants will be going into their first winter in 2025/6, so I have not tested their cold tolerance. However online sources say they are hardy to zone 5 or possibly 4.
The plant does contain milky white latex containing lactucarium which may have narcotic and sedative properties, so I'd recommend consuming in small quantities to start. That being said, modern lettuce also contains some of this compound, but it's likely been reduced quite a bit by breeding. I do not suspect Lactuca perennis contains as much lactucarium as Wild Lettuce (Lactuca virosa), which is used medicinally, but I don't know for sure. Levels are likely lowest in young plants, before they start flowering.

Shipping & Returns
By placing an order, customers agree to the shipping & refund policies detailed on this page.
Most orders are sent via Canada Post to keep costs low.
Shipping within Canada
We ship seeds via Canada Post within Canada for $6 to $8 depending on weight.
We ship seeds in Canada via regular letter mail, which is an untracked service, and usually takes 1-3 weeks to arrive once we fulfill your order, but occasionally orders take longer, especially to the Eastern provinces and rural areas.
Customers can now opt for tracked, express shipping options at checkout if you require faster delivery.
Larger bulbs and plants are usually sent via tracked flat rate box.
Shipping to the US
We require all US shoppers to obtain a Small Seed Lot Import Permit before we can mail your seeds. It's free to apply, and you will likely be granted the permit instantly, although some require additional verification via mail.
We recommend obtaining a permit BEFORE placing your order.
Please email your permit and shipping label PDFs to us promptly before or after you order.
If you do not email us your permit documents after one week, we will refund your order minus a $10 processing charge.
How to apply for your Small Seed Lot Import Permit:
- Please follow these instructions carefully so you don't end up with the wrong type of permit!
- Go to https://efile.aphis.usda.gov/s/
- Select PPQ-587 in the dropdown menu and click "Get Started".
- Please use the exact same name and address as on your order.
- Login and follow the instructions to obtain a permit.
-
Under the Commodity Type drop down, make sure you select the "Small Lots of Seed". See screenshot below.
- It's best to list "Eligible Taxa" instead of listing all the species you'd like to import so you don't need to worry about missing any species you ordered.
- Once you receive your permit, promptly email us 2 PDFs: a copy of your permit and a copy of the yellow/green shipping labels. Tell us which USDA station you want us to send the seeds to. If not mentioned we will choose one close to you. Our email is grow@cicadaseeds.ca
- Once we've accepted your documents, please contact the plant inspection station we are shipping to and let them know to expect your shipment. Station phone numbers can be found here (select "United States" then "Plant Inspection Stations" in the top 2 fields, then click "Search"). This reminds stations to check for your package, otherwise they may forget about it.
