I recently ended up in Stuttgart again, the big city of my youth.

I had to pick something up there, otherwise I would have given up in the morning when the booked train connection was canceled due to repairs, later trains were affected by signal disruptions or emergency medical calls and local transport suffered painfully from a lack of staff.

The usual chaos, then, which is best overcome with a lot of humour, flexibility and composure, as the train attendant proved to us with every announcement in the most beautiful dialect.

To everyone's delight, even if only hours later, in the EC on the return journey.

When I finally walked through downtown Stuttgart, admiring the then undecorated Christmas tree at the town hall, I came across a plant next to the market hall that I would envy in any front yard: an extremely beautiful, vigorous Christmas rose with greenish-burgundy flowers;

with a proud price of 98 euros, however, I didn't even have to think about it.

In addition, I had enough to carry and apart from a bread and "souls", classic with salt and caraway, no other capacities.

It stayed with the pretty thought - and the memory of an earlier story: years ago I had visited a breeder in Münsterland who specialized in the most diverse types and varieties of Christmas roses.

After a drive through the dark of winter, the illuminated greenhouses with their blooms seemed magical and from another world.

I learned so much about

Helleborus niger

, the Christmas or snow rose native to the southern and eastern Alps, and its colorful relatives from the buttercup family.

What we see on the market are mostly hybrid cultivars that have been selected based on the shape and color of their flowers and leaves and sometimes have descriptive names such as Cinnamon Snow, Pink Frost, Ice Breaker or Goldmarie, which really shines.

Old research material fell back into my hands while clearing out my office, including articles from magazines called

Plant Biology

,

Plant Systematics and Evolution, Flora

or

Scientia Horticulturae

and the

Journal of Phytopathology.

I had also consulted a "Monographia" by the botanist Victor Félix Schiffner, once a private lecturer in Prague, from 1890, because he had found all "forms known so far" of the genus

Helleborus

and an introductory description of what the powder of the root, “which is collected during various celebrations and prayers”, was used for in ancient times.

It arouses sneezing and sleep, cures paralysis, madness and dropsy.

In the appendix, Schiffner devoted himself to the crossing experiments, which is amusing to read, before delving into the "life story" that was written in 1994 at the University of Halle, or in the taxonomic analysis from 2011 at the University of Hanover.

Each specialist publication brings new details to light, confirming or rejecting previous studies.

In this way, you can find out so much more about plants that are best known for blooming in winter than just their suitability for being bestsellers.

Or did you know that

H. lividus

, a species restricted to the Balearic Islands, grows on Mallorca?

And up to an altitude of 1400 meters.

I love digging up such information about plants, but now the boxes are packed: the editorial team has moved and I'm breaking

FAS after fifteen years

to other worlds.

Finally, it only remains for me to wish everyone happy holidays and a happy new year.

And don't forget: water - even cacti need water, if only rarely.
