Flowers that rarely bloom?

Where can I find a list of flowers that don't bloom often?Flowers that rarely bloom?
Plants that flower this way are referred to as mast flowering or gregarious flowering meaning they have periodic pulses of coordinated flowering. These plants take several years to gather resources to flower in synchrony over a large area. Plietesial plants are similar, they grow for a number of years, flower gregariously, but then set seed and die where the other that mast repeat their cycle.

Juncus or sedges

For mast flowering plants there are the Strobilanthes. Specifically the Kurinji flower (Strobilanthes kunthianus) bloom only once in 12 years (last one in 2006). Other members of the genus share the strategy and flowering cycles range from annual to 16 year periods. Many seem to be plietesial flowering

Some passionflowers (Passiflora) have the rare eruptions


that produce reduced numbers of leaves and many flowers - Passiflora multiflora.

Certain bamboo are well known for their plietesial blooming. An Asian bamboo species, Melocanna baccifera, erupts in flowers about every forty-eight years, an event known as the Mautam.





Important Rain Forest canopy trees in the family Dipterocarpaceae, reproduce in gregarious mast flower-fruiting events once every 2鈥?1 years at irregular intervals but at least twice per decade in recorded history.

Masting specifically occurs in the tropic areas with variable rainfall patterns.

Five masting Chionochloa species in New Zealand respond to temperature cues in the previous growth season.
