how do they do it?

anyone out there, who can explain to me how a tiny little tree/weed etc, can grow through tarmac/roads etc???

i see this all the time, and realise they must be ultra strong to be able to burst through near solid objects and still survive.

click on this link for a pic i took the other day, thanks.

Truly amazing how a small seed can even germinate without much water or light and yet push right up through the most inhospitable environment! I found a place where the wild woodland cyclamen appeared through a tarmac'd drive, now that perrishing plant is hard enough to grow when planted as a corm so why did it grow there? Like so many calls of nature, only one can say how, but not me! I have seen so many strange things but as yet no way of knowing the answer.

The wonder of flowers, to be covered, and then to burst up,
Thru tarmack, to the sun again,

Hydraulic pressure - the same as used by mushrooms - we had one lift a paving slab to a height of 6 inches before the gills opened to spore but the cap was nearly 18" square - you can move the world with hydraulics...Loz.
