Purple & Red Foliage Pt. 1

My dream is to one day have a section of garden with no predominantly green plants.  This includes all trees, shrubs, flowers, groundcovers, absolutely everything.  My fascination with these plants has led to this post covering some of the plants in the greenhouse with interesting foliage.  Some are common but others you may have never heard of.  Anyway, here we go...

Setcreasea purpurea (Purple Heart) now named Tradescantia pallida

Zones 7-10 but can be grown anywhere as an annual

Does well as a houseplant, easy to grow, full sun is best

Ruellia makoyana (Monkey Plant)

Zone 11, full sun

Oxalis (Purple)

Zone 6 or above, does well as a houseplant

Iresine herbstii

Zone 10, full sun, does well as houseplant

Zebrina

Zone 9, full sun, easy, annual in colder zones, good houseplant
