  1. Cannas! My favorite, and they thrive in the hot desert southwest, with very little work. Yet, I rarely see them for sale with other plants. In fact, here in Las Cruces, NM, I’ve seen a lot of “hostas” in the stores, which is unimaginable to me that they would survive here.

  2. GREAT INFO! I was searching for heat-tolerant plants that can survive the brutal Houston, Texas climate. Any other suggestions out there from you H-Town folk>

    • 1. Ice Plant. 2. Sedum — many flowering varieties (I especially like Sedum “Autumn Joy” and Monarch Butterflies go crazy over it). 3. Purslane (aka Portulaca oleracea). This is not the double-flowered variety with the needle like leaves on this list. It is the single-flowered variety with rounded leaves. I actually think it is prettier than the variety on this list, and it comes in a variety of vibrant colors. We have it in window boxes in full sun and horrible heat in southern Louisiana. Nothing else would do well in those window boxes, but we barely do anything at all to this purslane and it thrives. We water it about once a week. Here are photos of just some of the colors it comes in. http://www.costafarms.com/plants/purslane

  3. When I libed in Houston I had TONS of the light green leaded begonias. Of course i had them in full shade, but they really thrived in their pots. Red, pink and white. Unfortunately, someone came up the apartment stairs and stole them all!!!!

  4. Most of these plants are weeds here in Australia’s harsh climate. Can’t we have a website with Australian HEAT tolerant plants. Y is it always American plants that pop up?

  5. We live on a brackish bayou on GuCoast MS, and bottlebrush thrives here, even when we flood with the saltwater….we do prune back after blooms…the only thing that did kill off 1 was a very hard freak freeze. ^ months of coastal heat, floods and storms have not killed off this beautiful shrub.

  6. Thank you for the information you have shared with us.

    I love gardening very much and i hooe to learn a lot from you.

    However, my biggst challenge in Botswana, Africa, is the harsh climatic conditiins. Our summers are extremely hot. I wish i could plant a beautiful garden of flowering plants that can stand aot of heat.

    Unfortunately our suppliers here only supply flowers tbat need intensive care.

    Would you be in a position to supply the plants you have suggested to Africa?

  7. Zombies are great. Love the heat. I live a little north if Houston and you can even plant the seeds in the blazing month if July. If you keep th watered they grow well. I have some beautiful Magellan zinnia hybrid only supposed to grow 2 feet tall but mine are 3 to 4 feet tall. Zinnias will fall over eventually in whatever direction they get the most sun.

  8. Lavender is renowned for its healing properties; simply smelling this flower is said to calm one’s nerves. Lavender smells strong, but pleasant. I highly recommend adding this flower to your patio to learn about its benefits and pleasant scent. It needs full sun and well drained soil. Lavender thrives in zones 5-9, but from personal experience, it also thrives (as a perennial) in zone 4. Humidity is not a friend of lavender, but it can be grown in more humid climates. Keep in mind that it won’t grow as well in high humidity as it does in arid climates.

  9. Since I moved to Texas, and am not great at gardening, I’ve done a ton of research and trial and error over the years…great flowers for Houston; Lantana, Verbena, Angelonia, Torenia, Cannas, knock-out roses, begonia of any kind, caladiums, vinca, pentas- all of these continue to flower in high heat and make excellent, low maintenance garden containers and beds. (Ferns, too! Especially Kimberly Fern, asparagus fern).
