To prepare your flower beds for planting, remove all weeds and other debris then spread 4-5 inches of organic matter over the top of the bed and dig it in to a depth of 8-10 inches. You can use compost, shredded leaves, peat moss, etc. as organic matter. After digging it in, plant your perennials and then cover the bare soil between the plants with an additional 2-3 inches of organic matter. This mulch will help suppress weeds, moderate soil temperatures and help slow water evaporation. You will need to water deeply once or twice a week to keep your plants happy and healthy. Here's a short list of perennials which grow well in the Texas heat:
Autumn sage (Salvia greggii); Baby sun/sunray coreopsis (Coreopsis grandiflora); Bearded iris (Iris xiphioides); Blue plumbago (Plumbago auriculata); Bouncing bet (Sapinaria officinalis); Cigar plant (Cuphea micropetala); Daylily (Hemerocallis); Firebush (Hamelia patens); Garden canna (Canna x generalis); Goldsturm rudbeckia (Rudbeckia x goldsturm); Hinckley's columbine (Aquilegia hinckleyana); Indian blanket (Gaillardia sp.); Lantana1 (Lantana sp.); Louisiana iris (Iris fulva x Iris giganticaerulea x Iris foliosa); Mealy cup sage (Salvia farinacea); Mexican oregano (Poliomentha longiflora); Mexican sage (Salvia leucantha); Moonbeam/Zagreb coreopsis ( Coreopsis verticillata); Pavonia (Pavonia lasiopetala); Perennial verbena (Verbena sp.); Pink rain lily (Zephyranthes grandiflora); Purple coneflower (Echinacea angustifolia); Rosemary (Rosmarinus officinalis); Sweet violet (Viola odorata), and White raid lily ( Zephyranthes candida). Best wishes with your flower gardens~
