Yes it is.
If you are looking for a gift to give to someone in your family, flowers are always a pretty good shout. Flowers are universally accepted as a nice, warm-hearted gift. Most people will appreciate it – the secret, though, is to do some digging and find out what kind of flowers they like to receive.
I suggest talking with your aunties closest family members and finding out what kind of flowers she would like. Any flower bouquets will be well-received, but you want to hand over something that suits them personally. But yes, flower bouquets are a smart choice for a gift that you know will go down well.
You might find some great local options, but you also should check online for other flower gift websites. Flowers are always a good choice, though, especially if you are auntie is someone who has a love of nature. Good luck, and I hope that she loves the gift received!
