Introduction

• Ornamental Herbs are important in retail
  nurseries as they can attract large number of
  customers.
• Ornamental plants are small in size and can be
  planted in pots and indoors.
• Ornamental herbs are mostly used in landscape
  garden as hedges, edges, cover crops, flower beds
  etc.
• Ornamental herbs are propagated by different
  methods like Seeds, cuttings, runners, bulbs,
  corms, suckers as main methods of mass production
  in herbs.

Propagation of Ornamental Herbs

• Suckers Gerbera
• Crowns Ornamental Pineapple
• Bulbs Tuberose
• Corms Gladiolus
• Tuber Begonia.
• Rhizomes Canna, Ferns
• Runners Sweet Violet
• Stolons Chlorophytum sp.
• Cuttings Hibiscus, Duranta
• Seeds Petunia, Marigold

Suckers

• Suckers are lateral branches developing from
  underground parts of the stem or roots in the
  soil.
• Gerbera produces numerous suckers, which can be
  split into many individual plants.
• While separating the sucker plant, care must be
  taken to allow each sucker with some roots
  attached to it.

Crowns

• Crown is basal part of the plant stem below
  soil surface.
• Crowns can produce new plantlets with independent
  shoot and root systems.
• Division of crown is a important method of
  propagation in herbs like ornamental pineapples.

Bulbs

• Bulb is a specialized underground organ
  consisting a short, fleshy, apical growing point,
  enclosed by thick fleshy scales.
• outer scales of bulb are fleshy contain reserve
  food materials. e.g. Tuberose, Bulbous Iris.
• Bulbs are produced by monocotyledonous ornamental
  plants.

Corms

• Corm is the swollen basal part of a stem whose
  axis is enclosed by dry and scale like leaves.
  E.g. Gladiolus
• Corm is solid stem structure with nodes
  internodes. Corm consist of food reserves.

Begonia Tubers
Tubers

• Tuber is the short terminal portion of
  underground stem. Food accumulates in tubers
  which causes thickening of the stem.
• Tubers produce buds which grow into new plant
  under favorable conditions.
• Begonia is an Ornamental herb propagated by Tubers

Rhizomes

• Rhizome is horizontal stem growing under or sub
  soil surface showing nodes and internodes like
  aerial stems.
• Rhizome is main axis of the plant, producing
  roots on its lower surface whereas leaves
  flowering shoots above the ground.
• Canna is an ornamental herb propagated by
  rhizomes

Canna sp.

Runners

• Runner is a specialized stem which develops from
  the axial of a leaf at the crown.
• Runners grow horizontally along the ground
  forms a new plant at each nodes.
• Ornamental plants Violets (Viola sp) propagated
  by runners.

Stolons

• Stolon is horizontally growing stems which
  produce adventitious roots when they come in
  contact with the soil / growing medium.
• Chlorophytum is an important ornamental herb
  which can be propagated by stolons.

Cutting

• Stem cuttings with few buds can be propagated by
  placing them under favorable conditions to
  develop a plant which resemble the parent.
• Propagation by Cutting method is commonly used in
  hard wood plants, which cost effective, quick and
  cheaper.
• The plants like Hibiscus, Rose, Duranta, Acalypha
  are commercially propagated by cuttings.

Seeds
Seed is sexual method of plant propagation.
Direct Seeding Seeds are planted directly into
soil for germination. e. g. Gomphrena
Indirect Seeding Seeds sown under protected
conditions, allowed to germinate and then
transplanted outdoors into permanent location.
e.g. Petunia
