These are Primroses flowers and have very sweet fragrance like roses. If you have some space which doesn't receive the direct sunlight, you can grow these plants. They are grown in winters and have bunches of flowers on the whole plants. The flowers last from 7 to 10 days. And we should only water them when the upper layer of soil becomes completely dry. For small pots and hanging baskets these are the perfect plants. I have these two colors in my home garden.
