Kniphofia, the Red Hot Poker
Summer features exotic Crinums and Hymenocallis as well as those shown here.
Bengal Tiger or Pretoria, either name is correct for this Canna.
Caesalpinia pulcherrima, known in Texas as Pride of Barbados.
Caesalpinia and Esperanza are good companions. Both
are easy from seed: Pride of Barbados may take a second
or even a third year's growth from roots to put on blooms.
Stachytarpheta jamaicensis, Porterweed in Purple and Coral, attractive to butterflies, one of my favorites. Cuttings or seeds, sometimes root-hardy.
All my Tropical Gardens are not in hot sun and all are not in brilliant colors.
In dry shade under a Live Oak tree grows a tropical garden of mostly Gingers. I can't expect Alpinias to bloom here, but the tropical foliage is just beautiful. Curcuma does bloom, as does Hedychium.
Hedychium, Butterfly Ginger
Justicias: White and Red Shrimps
White Garden beside the GH has white Lantana montevidensis,
and White Datura, White Pentas and White Echinacea, in sun.
Anyone who chirps, "I only buy perennials," has no idea what they may be missing. I only buy what I've researched and believe to be suitable for my garden.
Sometimes it takes a second look. Loropetalum, which we depend on for earliest spring color even ahead of azaleas, takes a second bloom in September. Not as spectacular as the early spring show, it is still worth a second look.
Dee Nash has a great post on Tropical Plants in the Summer Garden this week.
I could go on and on. I have another post to make featuring Muhlenbergia capillaris and other grasses.
