Beautiful, colorful landscaping! The tall grass is purple fountain grass (Pennisteum sectaceum 'Rubrum'), available from bustaniplantfarm.com (image credit). Looks like coleus and purple heart, and maybe begonias?
Choose a particularly stunning evergreen (such as golden 'Chief Joseph' pine, contorted 'Emerald Twister' Douglas fir, or white-variegated 'Horstmann's Silberlocke' Korean fir) and treat it as a specimen plant in your landscape. Selections such as these are so eye-catching they don't need neighbors. Learn more about 'Chief Joseph' pine. Learn more about 'Horstmann's Silberlocke' Korean fir.
