1. Flower Inflorescence Types
I will be able to explain how a flower inflorescence is grown on a flower and explain that type that flower belongs in.

2. FLOWER INFLORESCENCES
Flowers can occur signally as a Tulip
Or in CLUSTERS of FLOWERS or FLORETS

3. TYPES INFLORESCENCES INDETERMINATE DETERMINATE
Florets open from BOTTOM UP
Length of stalk is INDETERMINATE because stalk continues to grow as florets open
DETERMINATE
Florets open from the TOP DOWN
Growth of stalk is DETERMINATE by opening of first flower at top

4. INDETERMINATE TYPES Spike Raceme Panicle Corymb Umbel Spadix Spathe
Catkin
Head
Ray florets and disc floret

5. Spike
Unbranched inflorescence form consisting of a main stalk with stemless florets attached along its length
Examples: Gladiola
Hunter, Norah T., The Art of Floral Design Second Edition Delmar 2000.

6. Raceme
Unbranched inflorescence form consisting of a main stalk with florets attached along its length by short pedicels
Example: Lily of the Valley
Hunter, Norah T., The Art of Floral Design Second Edition Delmar 2000.

7. Panicle Loosely branched, pyramidal inflorescence form
Example: New Jersey Tea
Hunter, Norah T., The Art of Floral Design Second Edition Delmar 2000.

8. Corymb
Flat-topped, open flower cluster, blooming from the outside edges in
Example: Alaska Yarrow
Hunter, Norah T., The Art of Floral Design Second Edition Delmar 2000.

9. Umbel
Inflorescence in the shape of an inverted umbrella having pedicels radiating from one point
Example Hoya
Hunter, Norah T., The Art of Floral Design Second Edition Delmar 2000.

10. Spadix
Fleshy spike which carries numerous minute flowers embedded on its surface, usually surrounded by a colorful bract called a spathe
Example: Anthurium
Spadix
Spathe
Hunter, Norah T., The Art of Floral Design Second Edition Delmar 2000.

11. Catkin Elongated inflorescence of unisexual flowers on a woody plant
Examples: Birch
Hunter, Norah T., The Art of Floral Design Second Edition Delmar 2000.

12. Head
Petal-like floret attached at the perimeter dense inflorescence of small, often stalkless flowers.
Example: Daisy
Ray florets—linear,
Disk florets—tubular flowers found in the center of a composite or daisy-like flower
Disk Florets
Ray Florets
Hunter, Norah T., The Art of Floral Design Second Edition Delmar 2000.

13. DETERMINATE TYPES SOLITARY – one flower on stalk
Example: Poppy
CYME – like a raceme but flowering from top down
Example: Rose
