Sounds good. I agree African violets are generally easy to care for. As long as they are not overwatered or allowed to sit in excess water and don't put in hot sun and they are pretty hard to kill. Moderate fertilizer is sufficient to have them repeat bloom after a few months rest. They are available in large selection of colors and bloom styles.
Phalaenopsis - moth orchid - is also relatively easy to care for.
For my reply, I think the absolutely simplest to care for "bloom *beautifully* and die" type gift plants are flowering bulbs.
Again, the selection would depend on your location. For example, in North America at this time of the year -- heading into winter -- African Amaryllis is available in wide selection of colors, sizes, and bloom styles (large, small, double, frilly). paper White Narcissus are also often given and are easy and are fragrant. For spring bloom, hyacinths, tulips, daffodils, and grape hyacinth. Available as ready to gift, pre-planted in potting mix kits, they only need to be given a sunny location and watered occasionally. They are also available as grow-in-gravel-and-water kits. Generally speaking, only ways they fail are insufficient light.
With this type of blooming bulbs, it's just a question of starting them to bloom when you want them to. They bloom once and that's it. Although dedicated gardeners can bring them back to life year to year, they are generally considered disposable gift plants.
FWIW, another easy to care for (I.e. not easily killed) plant that is beautiful in bloom is Easter/Thanksgiving/Christmas cactus. For February bloom, I think "Easter" cactus might be available. There is a trick to getting them to rebloom, but the plant itself is easy to care for. The one I have is "Thanksgiving" cactus and it reblooms every year at this time of the year.
There are many flowering plants that are often given without thought to how difficult it is to maintain them. I think giving inexperienced gardeners difficult plants can have the effect of making the recipient feel guilty or inadequate for not being able to keep them alive/letting them die. But unfortunately the industry is such that they SELL plants that are not always suitable and end up dying soon after being gifted.
