In our post about “Foraging for Wild Cannabis“, I showed some pictures of wild C. ruderalis plants I had found, and was lucky enough to find at the right time to gather a few seeds.
These smaller, harder wild seeds seemed adapted to the local climate, and made me wonder if the auto-flowering properties of this wild plant could be crossed with a more “bud-productive” commercial strain (I chose a personal favorite, “Double Gum”) to produce an early flowering plant suited to outdoor growing in northern climates that would produce significant buds. The ruderalis strain produced flowers, but they remained small and leafy, even in a controlled grow. They do have a wonderful orange/pepper aroma that I’d love to experience in a larger bud.
Foraged C. Ruderalis seeds.
This strain of ruderalis seems to begin flowering around midsummer night (June 21st) rather than the autumnal equinox (Sept 21st), leaving the plant plenty of time to flower and spread seeds before frost can interrupt the life cycle. How I love this adaptable, wily little plant! Probably the escaped ancestor of hemp cultivation before prohibition of marijuana, life finds a way, and these fine-leaved, short plants pop up along roadsides, gravelly riverbeds, and vacant lots in parts of northern Europe.
I’m happy to report that pollinating a female Double Gum plant with flowers from a male C. ruderalis produced viable seeds that grew vigorously. (That’s the title photo above). Even more interesting is that the plant has grown far larger than any of the wild strain, yet has retained the slim leaves and lovely peppery-orange aroma of the father ruderalis. I’ll post updates as the buds develop – let’s see if mother Double Gum’s beautiful buds gene expresses itself over the next 6 weeks or so.
Here’s another peek at the plant – if you click for a full-sized view, you can see the fine clusters of white pistils that have developed in the last couple of weeks.
best regards

Cannabis Growing 
Hi, i have found very sativa like plants in Riga that already have developed brown seeds at the bottom nodes… i plan on collecting some more seeds as they mature… Could you post the image of th ruderalis bud that grew indoors?
Healthy young plants, I read that the auto trait is autosomal recessive, which means that basicly the F1 generation’s seeds 1/4 ff of the F2’s will have two copies of the auto gene, while the other 1/4 will have FF and the rest 1/2 will have Ff, which is the same as the F1
Will it be half as potent as the comercial 1?
Quite impressing. What about the Quality of the F1, F2 generation? Can you say something about it.
Impressive article. I am a Cannabis grower. good Foraging Wild Cannabis picture.
