Description: Black roses (roses of black color) do not exist in nature as such,
but nevertheless have been created in laboratories. Botanists have
manipulated roses' genes through preliminary cross breeding,
creating a hybrid black rose. They are often featured in fiction
with many different meanings and titles such as black magic,
barkarole, black beauty Tuscany superb, black Jade and baccara and
death varieties of roses. The flowers commonly called black roses
are actually a very dark shade of red, purple, or maroon.

How Do I Germinate Rose Seeds?
Growing roses from seed is not the quickest or easiest way to
propagate them. However, this method can provide more satisfaction
than others when efforts pay off. There are many idiosyncrasies
when it comes to different types of roses and what their needs are
for growing. But there is a basic method to cultivate rose seeds
and plant them successfully for future growth.
Cold stratification is the process of exposing seeds to a
temperature of approximately 35 degrees Fahrenheit. You can do this
by placing them in your refrigerator. Store them by placing them
inside of a folded paper towel that has been moistened with
half-part purified (bottled) water and half-part bleach, then
placing them in a zip-lock bag. Don't forget to mark the varieties
if you are using more than one kind of rose. Keep them in the cold
for 45 to 60 days. You can plant seeds immediately after
stratification if there is no danger of a heavy frost. Use a
mixture of 50 percent planting soil and 50 percent vermiculite, and
place seeds a half-inch apart from each other. Use small, shallow
trays as long as there is good drainage. Place them in direct
sunlight, or use grow lights for 16 hours a day. Keep moist with
regular watering. The third leaf that appears from the soil is the
true rose leaf. After two or more leaves are visible, plant the
seedling in its own pot. A 3-inch plastic pot will do. Make sure
you have it in direct sun or are using grow lights. Help it along
with half a teaspoon to 1 quart solution of Miracle Grow and water.
How to Grow?
1. Test the seeds before planting. Put the seeds in water and
discard the seeds that float. Seeds that float may be hallow. The
plump, heavier seeds that sink in the water have a better chance of
2. Purchase a flat container for planting the seeds. This will need
to fit into your refrigerator. Consult with your gardening center
to choose the best flat for your needs.
3. Mix equal parts sand, soil and peat moss. Consult with your
gardening center, as they may have a pre-made mixture that you can
purchase. You will need enough to fill the flat.
4. Fill the flat with the sand, soil and peat moss mixture.
5. Plant each rose seed -inch deep and space seeds 1 inch apart.
6. Place the flat in the refrigerator; the desired temperature will
be about 40 degrees F. Keep in the refrigerator for about three
months to germinate.
7. Remove the flat from the refrigerator and place in a sunny
window, where the room temperature is between 65 to 70 degrees F.
Water lightly. Do not overwater, and do not allow the soil to get
overly dry. Transplant the heartiest of seedlings to the garden the
Rose on soil not ask for much, just with some humus soil aggregate
structure can be good training as long as the following three links
will make good growth: Rose is afraid of
(1) Rose is drought tolerant plants, but it is afraid floods. It is
necessary use non-glazed bonsai pots of soil cultivation. The
principle is "do not pour water on it when soil is not dry. Wet it
completely when you pour water on soil.”
(2) Lend a high concentration of fertilizer (especially
fertilizers) will result in the death of local rot.
(3) All plants need sunlight. Rose like sunshine too. Fert
