Looking for an attention-grabbing new direction in your garden? I’m doing a makeover of a corner of my front yard featuring exotic-looking but perfectly hardy cacti and succulents. I know this group of plants is polarizing to some folks, but I grow lots of different kinds, partly for how their unique appearances keep my horticultural interest piqued, and partly because they are nearly zero care and tolerant of weather extremes, which is getting more important in our changing climate.
