The two pots of Hippeastrum 'Orange Sovereign' make eye-catching accents in this grouping. But my favorites in this picture, without question, are the foliage plants, particularly the Dracaena reflexa 'Song of India'
I do love flowers. Few things bring me more joy than seeing my outdoor garden in full bloom. In fact, I tend to err towards flowers outdoors--I don't have enough foliage interest going on there. It is something I intend to work on. Also, I do grow a few houseplants strictly for their flowers: Hibiscus rosa-sinensis, Hippeastrums, and Phalaenopis orchids all have exquisite blooms and rather dull foliage. I think the foliage of epiphytic cacti, like Schlumbergera and Epiphyllum is interesting it its own right, but I don't think I'd be as interested if they didn't bloom as well.
As beautiful as the Epi bloom above is, to me it pales in comparision to the foliage of this Aglaonema 'Siam Aurora'
But for the rest of my plants, flowers are strictly a bonus--a sign that the plant is healthy. (I've heard that sometimes sick or dying plants bloom as a last-ditch attempt to reproduce, but that hasn't happened to me yet.) Beautiful or intriguing foliage is what I look for when I go plant shopping. Oh, and as to that variegated vs, plain green thing: I covet variegated plants of all sorts, but I think the most beautiful plant I've ever seen was a healthy, shiny, deep green Dracaena deremensis 'Janet Craig'. Second place goes to a well-grown Homalomena 'Emerald Gem.' Both plain green, they just seem to embody the essence of "planthood" to me.
