Grave after burial

[Mummyonline]

We buried my DM a couple of month's ago. Her mound has gone down and we cannot put a stone memorial down until at least next February when the mound is completely flat.
We have put a wooden cross up and put flower pots on the grave every so often. We visit her frequently as she was such an important part of our life. I want to make the grave look a little less temporary. I was thinking of putting some small white pebbles around it's outline. I recently saw at another graveyard that people had grown pansies within the mound and they looked really beautiful. Otherwise are there pots of flowers that will last longer than the ones that I get that only seem to last for a week or so?

I planted a white rose on my DH’s grave, directly into the soil rather than in a pot. It’s lasted 27 years so far.

Second the roses. Also dad put snowdrops into his mother's so that in the grey winter days there were tiny white flowers poking through and better days were on their way x

My Dad died 7 weeks back and he is buried in the beautiful graveyard in our local Church and l feel he belongs there with his family and his friends he grew up with but we were faced with the same dilemma, he has a wooden cross as well and we put a vase of flowers there but it still doesn't seem enough, so l have bought a couple of yellow rose bushes and planted them there .
I am so sorry for your loss too OP .

Mummyonline, I lost my sister last summer. We were also concerned as to what to do to make it look more permanent until her headstone can be put up. I can pm a pic if you'd like? I'd hate to trigger anyone by posting it here. Grief is truly a pain like no other.
