Types of Chrysanthemum Flowers

Incurved and Pompon

There are three main incurved chrysanthemum classifications: regular, irregular and intermediate. These are further divided into early and late bloomers. The main characteristics of incurved chrysanthemums are their distinctive, globe-shaped blossoms and upward and inward curving petals. Regular incurved varieties have tight, densely packed petals on blossoms up to 6 inches in size. Irregular and intermediate types have much larger blossoms of up to 8 inches. Irregular varieties have densely packed petals at the top of the flower and slightly looser petals around the base and sides. Intermediate types have even, moderately densely packed petals all over. Pompon chrysanthemums tend to have much smaller blooms, averaging between 1 and 3 inches. Pompons are another globular type but the flowers tend to have a combination of upward and slightly downward curving petals.

Reflex, Decorative and Indeterminate

Reflex blooms have loose, downward curving petals, and the wide, 6-inch blooms have a flat top with a hidden center. Decorative types are among the most common varieties grown as houseplants or in containers. The blooms are around 5 to 6 inches, loose and fairly open with either loosely upward or downward arcing leaves. Due to the variety of possible petal formations, decorative chrysanthemums are often classed in the indeterminate category. Indeterminate varieties are those that do not fit correctly into any other classification, having irregular blooms or bizarre petal and foliage shapes, and those flowers that possess characteristics of multiple classifications.

Spider, Quills and Thistles

Spiders do not have the traditional petal associated with chrysanthemums but have long, drooping, tubular florets with a curl at the ends. The florets radiate out and downward from a large, flat center. Quill types have many short, straight tubular florets with a closed center. Thistle varieties also have tubular florets but have a wild, ragged, unkempt appearance. The florets appear randomly placed and vary considerably in length.

Spoon, Anemone, Single and Semi-Double

Spoon, anemone, single and semi-double varieties all share a number of characteristics, all appearing similar to the daisy. Spoons are wide, loose, flat flowers with long, thin petals radiating out and arcing slightly downward from a small yellow center. The petals have small, rounded dips at the ends, making them appear somewhat spoonlike. Single varieties have a single layer of tapered petals surrounding a bright yellow center, much like a large daisy. Semi-doubles are similar to singles but have multiple petal layers. Anemones have the outward radiating, tapered petals but also have a large, raised center covered in small, tightly layered florets.
