What varieties of stock are there? An introduction to the latest variety classification

There are many horticultural varieties of stock. By height they can be divided into 3 types: tall, medium and dwarf; by flowering period they can be divided into winter stock, spring stock and summer stock; by petals they can be divided into single and double types. The main cultivated varieties include the white “Aida”, the pale yellow “Carmen”, the red “Francesco”, the purple “Abella” and the pale purplish red “Incana”, and so on. Let us take a look together below!

Classification by height

Stock is divided by plant height into 3 types: tall, medium and dwarf. All types can be grown in pots, medium and dwarf types are used for flower beds, generally with a plant height of 30-40 cm, and tall types are used for cut flowers, generally with a plant height of 60-90 cm.

Classification by flowering period

Stock can be divided by flowering period into winter stock, spring stock and summer stock. Winter stock is sown in autumn and winter and flowers in winter and spring, summer stock is sown in spring and flowers in summer, and autumn stock is obtained by crossing winter stock with summer stock varieties and can be grown as an annual or biennial.

Classification by flower form

Stock is divided by flower form into two strains: single and double. In the double strain, after sowing there are both single and double flowers. Double flowers have high ornamental value, but their stamens and pistils have all become petaloid and cannot set seed; only single flowers can set seed. Good seed should produce about 80% of plants bearing double flowers. Single flowers should be grown in a place with sufficient light and good ventilation to help the seeds mature.
