Wild lupinus at the roadside to the High Tatra.

Very colourful, conditions certainly suit them

Definitely, Brian, as I unsuccessfully planted and seeded lupinus in my garden, because it is said, that Lupinus improves quality of the soil. However, it needs more humidity and less calcium in the soil, then there is in my garden.
It is also interesting, that seeds of wild lupinus are highly poisonous, while those sold in garden shops are not.

Lovely, we have them growing on the grass verges beside our local motor way...

That must be beautiful, Amy. Unfortunately, they bloom only a short period.

I'm always surprised that people passing by don't stop to pick them that would be a shame ...

These ones are along the road, but it is territory of the national park, so they are protected. Fee is very, very high.
