As a side note, and thank you
@DaisyI for pointing out this old thread from 5 years ago, there is now a plant on the market in the US (wide distribution), finally, which is supposed to be the true yellow-flowered K. thyrsiflora
Paddle Plant (Kalanchoe thyrsiflora 'Desert Rose')
so this line of supply will fill a gap in due time, and prove my earlier words wrong. They could have chosen a better name.
You'll find it's basically impossible to tell that plant from K. luciae based on leaf features alone.
