One of the main problems purchasing plants offline, is that unless they are flowering, it is difficult to find out the color of the flowers
The seller will tell that the flowers are of one color, yet when the plant will start flowering, the flowers will be of a completely different color
Many time the domain investor is purchasing plants because she wants plants with flowers of different colors to complete a set of flowering plants, with different colors.
There are some types of flowering plants which are easier to grow,hence the domain investor is looking for plants with different colors
Periwinkle, portulaca, butterfly pea are some of the plants with flowers of different colors
