For those wondering what flowers give color, I'd say all of them do, and our little guys do really enjoy a nice fresh flower petal to munch on.
There are some things to remember though. NEVER EVER give your crab flower petals from a florist's flower. They are heavily treated with pesticides and chemicals to keep them fresher longer, and can be deadly to your crabs.
If you feed flowers, pick petals from flowers not growing near the side of a road, due to toxin buildup from exhaust fumes and other contaminants kicked off the road by cars (oil, gas, antifreeze, etc.).
Only pick flower petals from flowers you know have never been exposed to pesticides, even from a neighbor spraying his flowers next door and the pesticides that could have been carried on the wind.
There are some flowers you will never want to give your hermies as they can also be toxic. Here is a good website with some food info for your hermit crabs: http://hermitcrabcuisine.com/
This contains a safe food list.
There are more links I am sure others will share, I am at the end of my break at work and dont have my list of links here to cut and paste in.
