Perennials - Experiences and Recommendations

So the following are always among those I consider completely straightforward:
Echinacin
Yarrow
Anemone
Sedum
Feather grass
Astilbe
Sage
Lavender (Yes, but it needs to be pruned properly)

All experiences from my first garden. That's why I have planted the plants that way again now. Hopefully, this will be confirmed again, otherwise I have wasted a lot of money

New (and therefore without experience report):
Astrantia
Globe thistles
Dwarf lilac

I am very curious to see how everything develops now. Except for one Echinacin plant, everything seems to have taken root.

I am so impatient

I have had good experiences in my garden with:

Fette Henne
Echter Sonnenhut
Scheinsonnenhut
Sonnenbraut
Staudensonnenblume
Schafgarbe
Salbei in mehreren Sorten
Ziest
Lupine
Phlox in allen Varianten
Thymian
(Zier)Disteln
Margeriten (da habe ich ua rote, sehr hübsch)
Herbstaster
Taglilien
Schwertlilien
Pfingstrosen
Königskerze (die wächst hier wild, immer da wo es ihr gerade passt)
Glockenblume (ebenfalls wildwachsend)
Berg-Flockenblume
Kaukaisches Vergissmeinnicht
Herbstannemone
Akelei
Bergenie
Bartnelken
Kreuzblättirge Wolfsmilch (wild)
Klatschmohn (wächst auch wo er will)
Prachtspiere
Vielblütiger Salomonssiegel (den mag ich eigentlich nicht, aber der kommt hier im Schattenbeet immer wieder)
Nachtviole

I think these are not all, but this is roughly what I have in the garden.

I really like these plants.. we have partly very sandy soil and they thrive wonderfully there...

Great mullein, balloon flower, and a large-flowered rudbeckia.

In addition, many petunias have self-seeded. Last year I bought a few petunia plants. This year they have come all by themselves

Best regards Steffi

I love hellebores, they bloom as early as January and still look great even when withered (Bild 1)
Furthermore, I like scabious, but they don’t seem to survive the winter here. Never mind, I planted new ones again (Bild 2)
This year I’m also trying a Geranium Rozanne, it’s supposed to be a perpetual bloomer and make it through the winter – we’ll see.
There are also mallows that are hardy, also a perennial bloomer. I planted two as a test.
Oh, I almost forgot: columbines in all colors also grow wild here. They survive the winter and just look stunning!
