Gardening to deal with winter flash floods. June 2007, just after we moved in. Floods! We have heavy clay soil, and the swamp monster will get you! Can I have my foot back, please?
July 2008. Floods, again. But now we have a buried drainage pipe to clear the driveway. We have gravel paved paths, and the flood waters recede quickly.
The raging torrent across the picture is the road. That water flowed down our driveway and into our garden.
Paving and floods
Nature wants the rain dispersed – not collected on a roof, with gutters, and then directed into an overflowing storm water channel. Overflowing because it is either blocked with garbage, or simply overburdened. That the rain can sink into the ground, which is not covered with hard paving – think of tarred roads, and concrete slabs. That the rain can sink in, because the ground is not baked hard with an impermeable surface like concrete, but covered with mulch, so the soil is friable, crumbly. Let your garden soil be a sponge to absorb rain, as nature intended it to. If you can’t get your trowel or spade in, then think of the plant’s delicate hair roots trying. Paving (gravel or loose slabs) needs to let through as much as possible of a sudden downpour.
Rain water tanks

The Ungardener said, why water tanks? They’ll soon be empty. Why bother? But the logic is, that you catch some of the excess, and then ration it out for the thirsty plants. Especially with the first of the winter rains, when the plants are all yelling “I said, I’m THIRSTY!!!!” What is kind of frightening is that about 10 mm, in half an hour, can fill our two 500 litre water tanks. So yes we agree it is worth it. Besides the cats prefer to drink rainwater, none of that nasty chlorine.
Swales
What is a swale? A hollow in your garden designed to take the overflow of a downpour, until it can distribute itself. Our house is square. First side drains straight into the pond, which overflows into
Plum-Creek, which overflows in turn into the swale at the giant/Spanish reeds – and eventually finds its way into the town stream. Second side goes straight to the reeds, and joins the (can be frightening!) overflow down the driveway. Third side goes to the rainwater tank, and overflows into the pond. Last side to the second tank, then
Apple-Creek.

Apple Creek swale was dug out on the 3rd, and those floods came on the 6th.
Ungardening Pond
The pond. Which leaked. Has been drained and repaired. And is slowly filling again with rain. The Ungardener carefully relocated dozens of frogs to the two creeks. Today I see at least two frogs have found their way (back) to the pond.
Pink rose pelargonium, with raindrops. The white one I didn’t plant. Suspect it is a common or garden … someone tell me. Has very fine filigree leaves. It is obviously part of the daisy family, but our indigenous daisies have petals of substance, like a lettuce leaf. This is like tissue paper. And ours have petals that are petal shaped, these, have two or three teeth.
Susan in the Pink Hat says Cosmos. (
Cosmos bipinnatus from Mexico,
kosmos - Greek for beautiful) The new camera has captured spoons on the Clerodendron that the naked eye can only imagine. And finally, the water lilies have buds, despite being out of the water for weeks. Just the roots are in water. Plants are in the shade. Going back into the half filled pond today. Then we hope those buds will realise their promise.
PS Mystery flower is Cosmos - thanks Susan. Greek
kosmos means world/people/universe - thanks
Ellada our Greek blogger. Serves me right for blindly quoting what I read. And the OED says
kosmos is order/ornament/world. Only the OED could tie those three words together. So - Mexicans - the flower is an ornament? Or is it - see the world in a grain of sand?
William Blake's Auguries of Innocence
To see a world in a grain of sand,
And a heaven in a wild flower,
Hold infinity in the palm of your hand,
And eternity in an hour.
