Variety traits

Lily bulb

Lilium L.

The lily bulb is evaluated by the 'size' parameter, defined as the circumference in centimeters at its widest cross-section. This indicator directly determines potential productivity, flowering intensity, and suitability for commercial forcing.

In the reference 216 varieties crop Lily, where this is mentioned in the description.

Size measurement is performed using calibration templates or a measuring tape. The indicator is recorded as two values, e.g., 12/14, where the numbers represent the diameter of the holes between which the bulb circumference falls. The size range varies from 10/12 to 22/+ cm, with the bulb size determining the number of buds: large sizes from 18/20 cm are capable of producing 5–7 buds, while small ones produce 1–2.

The minimum size for flowering depends on the lily group: for Asiatic and Longiflorum hybrids, it ranges from 10/12 cm, while for Oriental, LA, OT, LO, OA hybrids, and Trumpet lilies, it starts from 12/14 cm. In addition to size, professionals assess physical condition: firmness, presence of healthy roots, and absence of damage, as these are critical for successful plant development.
