Re: rainfall

Noreen, that was my mistake.  They do show TX with 5 zones.  Did you have a
chance to see the map at
Yes, rainfall can vary much more than the map shows.  But as several people
have noted, hardiness, heat, and rainfall maps are just starting points.
They give us something.  Then, as has been said of the Sunset system, every
gardener should fine tune with their own collected data.

I live in Zone 5 (old usda map), zone 6 (new usda map), zone 5 (ahs heat
map), and Pink (HCG rainfall map)  However, I have microclimates and special
protection measures that have allowed me to plant some zone usda Zone 7
plants.  I can construct a sand bed to allow me to grow Zone Yellow plants
or I can plant some Light Green Zone plants under the eaves where they won't
get as much rain and make sure to avoid giving supplemental water.  And I
can make sure that Zone Dark Green plants DO get supplemental water.

Maps are a place to start.
