Interesting view of Perennial Flower, mostly this kind flower easy to shape, so home garden and public places garden in to sow plant, easy to maintenance and growing duration is only 5-6 weeks. Home back yard and front yard spot are best point to sow, before to sowing some point keep in mind, now we are discussing, land , color , water , temperature and plant pattern those are important fact. For pant growing need a quality and fertile land, then need to water means 1 day in two time water supply to plant, you can sow group plants of different colors, due to garden appearance will be change. I have some top Perennial flower they are ornamental grasses, ferns, hostas, bushes, shrubs and trailing vines. See the some bushes designs.
