Walking along the River Severn on a lazy
Sunday just gone, it was hard to ignore the weather - which was milder, the
water – which was lower, and the trees – which were blossoming. By no means was
this the ‘boom of summertime’, but it was something of a rumble at least. Something I've never really thought about is
how plants and animals just seem to know when spring is here.
Apparently, plants know the time. The
Mother Nature Network tells me how…
‘Plants have genes that suppress flowering and growth, and
these genes are time sensitive. Plants actually register how many cold days
have passed, and when enough have gone by, the genes are temporarily
deactivated, allowing flowering and growth’.

‘One particular species of plant, arabidopsis or ‘thale cress’, had its entire genome
sequenced in 2000. Scientists discovered a gene that they, in a fit of
creativity, named ‘COLDAIR’, or in Latin frigida (seriously). COLDAIR
gets switched on after that long period of freezing temperatures and
progressively turns off a gene responsible for inhibiting flowering, over a
period of six weeks.
Then bees do it with
them. SCIENCE!’
So, where do the bees come from? Where do
they hide away all winter? Do they migrate as birds do? Do they hibernate? No.
They form a ‘winter cluster’.
Besides sounding like a seasonal breakfast
cereal, this is another amazing natural mechanism that ensures the survival of
our honey bees. According to the Gardening website ‘Dave’s Garden’…

So that's where spring goes when it's not on its way!
