the bushy plant is healthy and vigorous, the twig in the next pot lost its leaves, so I wait to see if it is alive!
When the bushy plant is left outside of the greenhouse, the leaves go strong red, but seem to be happy!

Fascinating :o)

Indeed. Keep us posted.

A local garden centre think that the bushy plant may be a gentian, but it's now growing very much like a sweet william!

The twiggy plnt is a goji berryl
