i live in mid-north GA. recently i've been given leeway to renovate the flowerbeds of the house i grew up in. they've languished since my mother died 20 years ago, my father is a farmer but has no use for ornamentals. first i started working on the border of the east facing once rose now tomato beds, filling in the border by moving liriope and adding the marigold and johnny jump ups i remember (very hard to find colored viola seeds). that worked, then i planted sunflowers in the north facing bed, which had only a few tired shrubs. now i want to really do something to the west facing bed . now, i'm huge SF fan and i remember a story by HPLovecraft called 'the color out of space' about a meteorite infecting this valley so the plants all changed to some unnamable color. then there's the 'War Against the Chtorr' about earth being invaded by an alien ecosystem that is red-pigment based..... what i want is for the bed to look like its being overcome with purple. i want purple flowering vines and purple leaf sweet potatoes choking the shrubs and to go with the purple hyacinths and crocus i remember from childhood, purple crinums, purple leaf elephant ear, etc. the new plants should show wild, verdant (well, purple-dant) growth over the tame, box cut shrubs. but of course, it's all carefully arranged and tended. my tentative list: vines: passionflower (very alien), bougainvillia, clematis, morning glory, maybe tweedia bulbs: allium, crocus, hyacinth (grape?), taro, purple calla lilies? i know i can grow plants, but i've never attempted something this ambitious. and aesthetically questionable. how hard would this be to maintain? will it eat my house (not sure i'd mind)? i'm trying to select for overlapping blooms and tolerance for our soil types (tired azalea bed over red clay). any pointers?
