Just a note for those who may not have thought about it of which
Elly's email is a reminder.
Many drought hardy plants have been sourced from climates that are
extremely cold in winter, ie ice and snow.
These have relocated well into medit climates and grow in the cool mild
winters and easily cope with the dry summers, basically shutting down when
water becomes scarse.
To these plants its a case of growing when there is available moisture.
The extreme cold of a northern European or Canadian winter places the same
moisture stress on a plant as a dry as a bone summer in Australia or
California.
Water as ice can't be used by a plant so its a drought until the thaw as far
as that plant is concerned.
Of course many of these cold climate spp. have other particular adaptations
that help minimise moisture loss, all usefull in dry climates as well.
Cheers, Rod
