I have an Epipy that has a very large pink flower but the last season it has turned a smaller white flower. I did change the soil and I think it may have been that. Can you change it back to the pink? Regards libby
I am not sure what an Epipy is- do you know of any other name for this plant?
Flower colors can sometimes change because of changes in the pH of the soil. High pH (alkaline soil) typically causes flowers of some species to turn pink, while low pH (acidic soil) can turn them blue or other colors. Here's how it works with Hydrangeas:

Or, this could be an example of a "sport":

How far to cut back my astilbes, hostas, daylilies, coneflowers, black eyed susans and gladiolas when cleaning up my garden for the winter in Michigan?
Hostas, daylilies, gladiolas, coneflowers, and black eyed susans can be cut back in fall a few inches above the ground after the foliage dies.
Astilbes can be cleaned up in spring or in fall after the foliage has died. If cutting them in fall, cut about 3 inches off the ground to avoid damaging next year's buds.
Coneflower foliage should be left until spring to protect the roots, but seed heads should be removed if you don't want them to reseed.
I have several kinds of flowers, from roses, azaleas, ruellias and some I don't know their names. I bought all perennials this year and I'd love for them to come back so I don't have to keep wasting money every summer. Do I need to cut them down? Or prune? I've read a ton of sites and none of them are helping me. I live in Mena, Arkansas. It rarely snow here and never below zero. it might get in the 20's but not usually. Please help! Thanks, Leah
Most perennials will need little care or attention except deadheading or trimming back as they go dormant for winter.
You can trim away any spent flowers. Most perennials will die down naturally or you can cut down when they are done flowering.

At the end of their cycle, do they reseed?
These question has many variables.
If a plant produces seed and it is provided the needed environment to seed; and the seed is viable.
Many plants are hybrids and the off spring may not resemble the parent plant.
It is best to research each plant individually to learn if it reseeds itself.
