It is less known that geophytes may remain underground during the growing
seasons (Rabotnov 1969). It is named prolonged dormancy – a
phenomenon in which a perennial herbaceous plant does not sprout during
the vegetation period.
Dormancy implies a state of inactivity without growth however complete
inactivity is rarely demonstrated, bulbs often grow and root elongation can
occur during dormant season (Lesica & Steele 1994) but plants do not
sprout.
