  Grow a lush flower garden in hot conditions by choosing from among the many bright and hardy plants that tolerate -- even thrive in -- such weather, and which also spread liberally. Many of these plants were once considered "wildflowers," but gardeners have discovered their value and are filling their beds with these self-sufficient bloomers that come in all sizes, shapes and colors.
  
  

Coreopsis

  With its tall slender leaves and long-stemmed daisy-like flowers, coreopsis has become a staple in no-fuss gardens. Clumps of coreopsis will grow nearly anywhere there is soil and sun. Heat doesn't bother it, and coreopsis self-sows prolifically, with new clumps appearing yearly, often in places far away from original plants. These can be easily transplanted to different spots. Flowering in late spring and continuing through early fall, coreopsis comes in orange, maroon, red and variegated types.

  Coneflower is a true prairie plant and welcomes all weathers and soil conditions. It self-propagates well but stays more contained than other self-seeding plants. Also known as echinacea, this plant flowers in midsummer and continues through fall, sending out tall stalks with flower heads of drooping rosy purple petals surrounding bulbous orange-brown centers. Coneflower can be found in additional colors of white, orange and maroon. Dead flower heads attract finches, which favor their seeds.
  
  

Yarrow

  Yarrow is another field flower showing up in home gardens. Also known as achillea, this plant spreads so prolifically that gardeners may find it a nuisance plant after a couple of years if it's not contained. It produces feathery, fern-like leaves and tall stalks with flower heads made up of tiny florets. Yarrow is usually white or yellow but can also be found in pastel shades of pink and purple, and deep red or maroon.

  Gaillardia, or blanket flower, grows low and bushy, sending out graceful serrated leaves and pert, yellow-tipped, orange-red petaled flowers with dark brown centers. It prefers full sun but will grow in part-shade as well. Growing in clumps, blanket flower thrives in hot, arid spots and is self-seeding. Its flowers make pretty fresh-cut bouquets and can be dried as well.

  Also called sea lavender, statice has leathery, gray-green clumps of leaves at its base, with branching, almost leafless stems. Its small, delicate flowers appear at the tops of these arm-like structures and are protected by a papery envelope. Statice spreads easily and flourishes in hot, dry conditions and many types of soil. It prefers full sun. Flowers may be white, pink, purple, blue, lavender or rose.
