The number of flowers open on the inflorescence at one time. The way that flowers open can impact on their pollination by insects.
One flower open at a time: a pplies to plants that have a single-flowered inflorescence and to species with a mulit-flowered inflorescence where one flower opens at a time and is shed before the next flower develops. |
Multiple flowers, opening sequentially: the inflorescence is multi-flowered with the flowers opening sequentially, usually from the basal flowers upwards but occasionally from the apex downwards. |
||
All flowers opening simultaneously: the inflorescence has multiple flowers. In some species all these flowers open simultaneously, in others groups of flowers along the inflorescence open together. |
