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.
