Water Harvesting Designs that Work
This Tucson-area tour, October 19 from 9 a.m. to 3 p.m., offers useful ideas to retain precious rainwater on your landscape, rather than watch it flow away to storm drains. Visits to residences will cover site resources and constraints, and the owner's budget. Focus is on design ethics, site observations, and doing more advanced runoff calculations. It is geared toward those with some experience in rainwater harvesting.

Cost is $65, which includes materials and a lunch of native foods. Participation is limited to 15 and registration is required. For info, call Barbara Rose (520) 572-7221; or go to: http://www.sonoranpermaculture.org.

Favorite or New Plant

White Prairie Clover
A deciduous perennial also known as scruff prairie clover, white prairie clover (Dalea albiflora) blooms from summer to fall with tiny white flowers surrounding a cylinder-shaped cone. It is a larval host plant for the dogface butterfly and is covered with pollinators when in bloom. It is found growing in many places throughout the Southwest's mid-elevations, taking full sun and limited water, although it is most lush during summer monsoons.
