I love both! I love cut flowers because they bring my garden inside. The colors brighten my mood and my rooms and seem bring a feeling of life to them. Outside, my flowers brighten my yard and my spirits. Because I plant so many different kinds of plants and bulbs, I have flowers in my yard from the end of February through the end of November (i am in NJ, zone 6). My "flowerless" months are spent inside with catalogs as I decide what to plant in the spring.
I prefer live flowers or potted plants in the house.It is nice to keep potted plants the whole year round so that you can see them flowering at certain times and tend them in between.I do understand why people like cut flowers but they are just not for me.
I love to grow things. When I was back home in Maine, I'd have flowers everywhere, as my father had planted many varieties. There were lilacs, too, which I would cut and bring inside, as they smelled so nice. Still had the flowers, outside, though
I love flowers and grow them in my yard but I cannot bring myself to cut and bring them inside-- so I go out everyday they are blooming and enjoy them there. Plants are alive and I do not want to rob them of the one thing they work so hard to produce. So the answer to your question is live ones.
Try bulbs like lilies, tulips, daffodils, alstromeria, hyacinth, etc. They will store all they need to produce beautiful blooms each Spring or Summer to be enjoyed indoors or out even in the coldest climates.
I would much prefer to have live flowers. Cut flowers are only going to last a week or so. If I get live flowers, I can plant them in my flower beds and enjoy them for years! My hubby used to get me cut flowers, especially on Valentine's Day, but I asked him to stop wasting his money and buy me live flowers instead. He bought me a miniature rose bush some years ago and I still have it. I actually wrote a hub about the miniature rose bush - a great gift for any occasion.
Flowers are lovely in any form and always cheer me up!! I try to grow for my own cutting garden but often buy them to put around the house for parties and my own pleasure.. When I am buying flowers to send as a sympathy or get well gift, I usually opt for a flowering plant like an azalea, hydrangea, or something w/ bulbs that can be planted later for continued enjoyment.
