There is always a risk sending anything abroad. It is shocking and bordering on criminal because the flowers should have reflected the purpose at least. If you are able to and want to send flowers, choose a company who allows payment through pay pal. That way you have more security.
If I have gifts to send, or flowers, I always send via pay pal because it is much safer. Of course the recipient has to be able to withdraw the money from a pay pal account.
I first joined pay pal in 2006 and have found it to be one of the best methods of paying for anything, and sending birthday money. I also pay my carer via pay pal, which is a bonus for me. I pay the balance of my credit card off each month, so interest is never paid. I know that if I pay through pay pal and I do not receive the items, I will have my money refunded.
