Mini roses are more correctly called miniature roses and have flowers that range in sizes but are generally smaller than a standard rose variety. All miniature roses are variates of Tom Thumb, Oakington Ruby or R. Rouetii varieties, according to the Old Rose Garden and Beyond website. Starting mini rose plants from seeds can be a time-consuming task because they must be properly prepared prior to planting.

  1. 1

    Fill a cup half full of cold water and place all of the miniature rose seeds into it. Allow the cup to sit for approximately 1 minute and then scoop out any rose seeds that are floating and discard them, since they will probably not germinate. Place a paper towel over the top of the cup and drain out the water.

  2. 2

    Lay a paper towel on a flat surface and arrange the miniature rose seeds on top of it in a single layer. Cover the seeds with an additional paper towel.

  3. 3

    Fill a bowl with a mixture of 1 part distilled water and 1 part hydrogen peroxide. Pour the mixture on top of the paper towel slowly until it is thoroughly moist. Discard any unused liquid.

  4. 4

    Insert the paper towels into a resealable plastic bag and close the bag tightly. Place the bag into a refrigerator that maintains a temperature of 1.11 to 3.33 degrees Celsius and leave it there for at least six weeks.

  5. 5

    Fill a seed tray with a mixture of one part potting soil and one part vermiculite until each of the tray compartments are half full. Insert a single miniature rose seed into each compartment, and sprinkle the top of the seeds with 1/8 tsp of anti-fungal powder. Cover the seeds with an additional 1/2 inch of the soil mixture.

  6. 6

    Water the soil until it is completely moist and place the tray in an area that receives direct sunlight.

  7. 7

    Continue watering the soil as needed to prevent it from drying out. The rose seedlings should sprout in approximately six weeks.
