Tanacetum leontopodium / Pyrethrum leontopodium

[Leucogenes]

Hello,
I have just received eleven seedlings of Tanacetum leontopodium (Pyrethrum l.). I really want to establish in Alpinium. With a cover of glass. Should I plant them later this year, or better put by next spring the cold frame?

Thanks for your help.

Thomas

Thomas, In my experience Pyrethrum leontopodium does not survive for a longer time in the open
garden without overhead protection in the winter. I lost it several times, a place in the alpine house
is better for this alpine gem.
Planting next spring is surely safer.

Best thanks for the Information, Rudi.That's how i'm gonna do it.
