Healthy and established. Small enough to carry on train. But fairly big! You can keep it in the pot. Or you can plant it in the garden
I will bring to station and pass over the ticket barrier so that you can keep traveling on the same ticket.
Has been blooming for over 14 years in this pot, goes down to stubble every winter and always comes back up !
Peonies like loads of sun in the Spring. After blooming you can move them to a less sunny spot.
The second photo is of a bloom last year. The first photo is of a bud today before opening up.
There is also a ground cover plant growing in the same pot, with small pink pompom flowers and reddish leaves. This can come back every year too if it doesn't get too cold, but you can also harvest a pompom at the end of it's life and use it to re-seed the pot (or somewhere else as well).
Once the Peony plant has spread sufficiently inside the pot, it can be gently split into two plants (best done in about early February, just before the spring push comes). The plants may not be as robust the first season after splitting. But peonies are fundamentally robust so even if they appear to completely die off in winter they always send up new shoots in Spring!
