Could I put Creeping Jenny on a grave because I don't want stones or grass?
Yes, you can do that. The common form of Creeping Jenny can be invasive in some areas though, so you may want to keep that in mind. The golden variety is less invasive, but still can cause problems. Creeping jenny also only really does well in marry soil, which you typically don't find in cemeteries.
A good alternative would be to look at creeping sedums. There are literally hundreds of varieties available. Many have a similar look to creeping jenny but are not as invasive and are very drought tolerant. They also need little care to thrive. All of these would make them ideal candidates for a gravesite groundcover.
Will creeping jenny grow in sand? just made a gravel path with a 12 inch strip between it and the house that is filled with at lest 6inch deep sand. I would like to fill with low growth filler.
This will grow just about anywhere. I think it will take off just fine in sand as well. It is drought tolerant, but you will want to keep it watered some in the sand, as this will tend to dry out fast.

We planted our Creeping Jenny about 4 years ago and it did well the first 2 years, but with the hot summer last year, eventhough we watered every day it, both creeping jenny and the ajuga started to die. We lost a lot of the plants. This year some of them came back and we have not had the heat yet like last year and we have been getting adequate rain as well as we water and the plants are already dying. Do I need anything else in the soil like lime?
Daily water during a dry spell is likely too much water. It could cause the plants to suffer root rot if the soil is not well draining.
Excess moisture can also lead to disease or fungus issues.

The plants are well established and have done well for 3 or 4 years.
It was probably the larval form of some sort of sawfly. They can quickly decimate the host plant. Here is some info from the Univ of IL:The sawfly larvae are whitish to pale green with light tan heads and obvious black eyes. Fully grown larvae are a little over one inch long. Although sawfly larvae look similar to caterpillars, they have more than five pairs of prolegs. Not being true caterpillars, they are not controlled with Btk. Spraying the foliage with carbaryl, Sevin, or a labeled pyrethroid will provide control. Do not spray the blossoms to avoid killing bees and other pollinators.

My cat loves to roll in my patch of creeping Jennie. The other day I found her trying to eat it. Is it safe for her to eat? I've planted some catnip but she ignores this and insists on the creeping Jennie. Thank you
Creeping Jenny is not listed as toxic to cats. Always check with your vet.

Creeping jenny is perennial in your area so you don't need to bring it in for overwintering. If you just want to grow it inside it can be grown in a pot as a houseplant.

Hi! I have never attempted anything with flowers before. I'm being adventurous and trying to plant a few things. The Creeping Jenny was a hanging plant that I purchased. Right after I brought it home, it started looking sickly to me. Is this normal?
It may just need the spent flowers sheared off; it grows quickly. Here is more info about creeping jenny:
