These 2 wild flowers have popped up in my garden this year, they weren't there last year, the first summer I was there. Hardiness zone 4, Central Asia. The pink flowers are 30-50cm in height, about 20 separate plants in a shady area, with spindly leaves just underneath the flower. The yellow-flower plant is more than 1m high, thin and tall reaching up, only one of it in a sunny part of the garden. Both are quite attractive set against a backdrop of grass and camomille.
I'm thinking #2 looks more like Hypericum, maybe perforatum. Look for a bunch of small, translucent pores in the leaves when held up to the light to be sure....
#2 does have the red/purplish tint of Hypericum perforatum, but the stamens seem less bushy-like as in the specimens I see in my area. Maybe this is due to environmental factors, the plant's growth stage, or it could be a related species. Good idea to look for those pores in the leaves.
#2: It's Hypericum perforatum, the pores are there. Thank you! Wikipedia says: Depending on environmental and climatic conditions, and rosette age, St John's wort will alter growth form and habit to promote survival. That would explain why it looks different around your parts, pathe. As to why I didn't see it last year, apparently the seeds can persist for decades in the soil seed bank, germinating following disturbance.
