Hello. This looks like a Mum. They die back in the winter with seasonal weather changes.
Typically these colorful plants are planted in the fall. Many times they do not come back. If you are in a gentler planting zone - it could return to life. Can be called a finicky perennial— good luck with your plant. Here’s a link that might be helpful.
And be aware that mums purchased at the supermarket in the fall are usually 'hot-house' plants. If you can source field-raised mums, they are far more likely to survive winter.
Cut it down to 4 inches high. Dig it out. Using sharp pruners, divide the plant into smaller plantlets (portions with stems attached to roots). Remove the big rocks out of the garden bed. Rake the soil, add some organic matter (leaf mold, compost, peat moss) to the soil. Plant the new plantlets so that they fill in the bed (1 - 2 feet apart). Cover the entire bed with leaves until spring. Water the plantlets in and water every few days. In the spring, remove the leaves and fertilize the plantlets. Mulch the soil around the plantlets. Make sure they don't dry out during the summer and by the following year the bed will be overflowing with flowers. ENJOY!
OR, just cut it to the ground and hope it comes back - mums are a pain.
Cut it back to find green stems in the spring, then they should start again. You can cut it back now if you wish though.
Hi Irene: Here's an article on mums:
But, looking at those leaves, I'm thinking it may be a geranium. Here are some sites about them:
You can use the app plant snap which can ID it for you and you can look it up on how to care for it.
It looks dead. I would just dig it up and compost it.
Looks like a Mum, I would cut off the dead stems and hope for re-growth. The dead parts can be composted.
your question and photo was posted twice for the same issues please review the answers on both your posts
I would transplant it somewhere you would like it in your garden or in a pot. If it is a mum, it might not grow back if there is a hard frost... I'm not sure what zone you are in.
Hi Irene, that looks like a Chrysanthemums (often referred to as a Mums). You can cut her down quite hard (about 2" or 5 cm off the ground). Add some mulch and she'll be sprouting new growth as soon as it warms up in Spring and you'll have a whole bush of beautiful flowers again in the Autumn.
