Rosa

Common Name(s):

Phonetic Spelling
RO-zuh
Description

The genus Rosa is native to the Northern Hemisphere.  They are attractive deciduous flowering shrubs or vines in the Roseaceae (rose) family.  There is a wide variety of sizes including shrub roses, vine roses, hybrid teas, English roses, and old garden roses.

Roses require full fun and organically rich well-drained soils.  Roses are relatively heat tolerant.  Deadheading the blooms on healthy plants will promote growth, until the end of summer then deadheading should be stopped to allow the plant to start its hardening off process before winter.  These high maintenance plants require yearly pruning but pruning can be different depending on the type of rose.  In general other than the removal of dead, diseased or dying tissue, roses should be pruned in the spring. 

Roses are grown for their incredibly beautiful, often large, and fragrant solitary blooms.  The flowers are often  white or in the warmer color pallet of pinks, reds, yellows and oranges.  True roses have 5 petals but many have been bred to have many many more.  The leaves are compound with toothed edges.  The sharp protrusions on the stems are actually not thorns but rather prickles and they can vary in intensity from species to species. 

Plant in formal English or Cottage gardens, cutting gardens, or planted at the back of a border.  Using tlarger speices as a hedge they can provide some security with their sharp prickles. The vining roses can accentuate vertical spaces in the landscape.  Small or teacup roses work well in containers.  More fragrant selections do well to be situated near a patio or walkway where their scent can be enjoyed.

Quick ID:

  • Flower parts in multiples of five (for example, sepals, petals, stamen, and pistils)
  • Prickles
  • Alternate and serrate leaves
  • Usually carotenoid colored petals
  • Generally fragrant
  • Fruit called a hip

Insects, Diseases, and Other Plant Problems:  Roses suffer from many insect and disease problems.  Pest problems include thrips, mites, aphids, scales, and whitefly. Disease problems include botrytis, blights, powdery mildew, leaf spots, and anthracnose.
