Planting flowers

Hubby and I were planning to plant flowers someday so the other day, yesterday and today we went to stores to look of what flowers we like to plant and pots for the flowers we choose and for my lemongrass. We found the flower and pots we like and came back today for more. I like some of the flowers but didn't buy them because they don't live the whole year. Hubby is okay with it but I like the perennial better so I don't need to keep on buying flowers and plant them again. Buying annual plants is like throwing money. Though there are some annual plants that I really like but I don't want to waste my time, effort and money when after a couple of months they die. Besides, we don't have the space we need for planting flowers coz we live in an apartment. Anyways, we only get a few flowers to start with and experiment if they really live longer. I'm planning to put them inside the house also when winter comes. Don't know if it works though but maybe it will. :)
