Characteristics of Old Garden Roses: Moss Roses

If your looking for something a little bit different, take a look at moss roses. Their sepals, calyces, and pedicels are covered with a growth that looks like moss. This growth is actually prickles and oil glands that have been modified by natural mutation mutation. It is is sticky, hard to the touch, has a piney fragrance when touched and gives a unique look especially when the plant is in bud.
 

The mossy growth first appeared as the result of mutations in Centifolia roses about 300 years ago. Further mutations and interbreeding with Damask roses have further enhanced moss roses and increased their variability. The Victorians who were especially fond of oddities especially enjoyed moss roses and most were bred from 1850 to 1870. They are difficult to find in the trade now partially due to propagation problems.

Most moss roses are pink, with some being white, red or mauve and at least one being yellow. They tend to be very fragrant, andprickly. Older ones are once blooming although newer ones with more Damask in their background are more likely to repeat bloom.
