Plants That Can Survive Hot Climates

Some parts of the country have a different understanding of what the word “hot” means. A hot climate is one where garden retailers regularly throw out the plant care instructions and replace “full sun” with “morning sun,” because very, very few plants can take the blistering heat of a summer’s day in these regions.

With that in mind, we gathered the top performers from four different field trials in undeniably hot climates: South Florida’s Costa Farms; sweltering Louisiana State University; and two Texas sites — Texas A&M University and Dallas Arboretum.

Check out a photo gallery of all the top performers. Also, here are a few notes about weather conditions and trial rules at each site:

Dallas Arboretum

“We conduct trials year round that include annuals, perennials and bulbs, with roughly 3,000 entries per year,” says Dallas Arboretum director Jenny Wegley. “This year’s weather has been one for the record books. We had several snow and ice events this winter followed by record breaking rainfall and very little sunshine in the spring. The rain stopped once summer hit and during July and August there were multiple weeks with highs well over 100 degrees. This year we added quite a few vegetables to our trial line up including tomatoes, peppers, squash and watermelon. Our trial gardens are open to the general public that visit the Arboretum, and edibles are always a crowd favorite. We evaluate each entry every two weeks and rate them on a scale of 1-5 in the following areas: leaf color and quality, plant vigor, floral stock display and flowering uniformity. We believe this gives an accurate representation of how the plant performed throughout the season.”

Texas A&M

Planting dates: Trials were planted in the field starting in late April for crops like trailing petunias, and through late May for crops like vinca.

Number and kind of entries:  More than 500 entries were trialed of more than 70 species. Most were annual bedding plant species, but a significant number of herbaceous perennials were included.

Climate conditions: Conditions cool and wet through May. “We had a record 14 inches of rain in May, which took us over our average annual rainfall for the year,” says Brent Pemberton, Professor and Regents Fellow at Texas A&M. “June continued to be warm and wet. July began a six-week period with no significant rainfall. The latter part of July and the first half of August were very hot and dry. Late August September were seasonably warm, but with long periods between limited rain events. Weather details can be found here.

“A new approach that I have tried the past couple of years with geraniums, that I have expanded to dahlias, is to put one replication in full sun and two replications under 30% shade,” Pemberton says. “I have found that trialing these two species in shade is more representative of how we would grow these species in this part of the country. For example, plants would be sited with morning sun only or in containers on patios with protection from the heat of the day.”

Louisiana State University

The trials take place at Louisiana State University’s AgCenter at the Hammond Research Station, which is located in Hammond, LA. The gardens experienced excessive rainfall March through early June, but was then followed by July and August with 43 days of 96 degrees or warmer with 0.60 inches rainfall.

Costa Farms

Every spring the Costa Farms’ research and development team trials some 500 varieties of annuals, perennials, and tropical plants from plant breeders around the world. All varieties are tested in Miami.

The trial season was relatively dry, with less than 4 inches of rain until late April. Then there was a heavy rainfall of close to 5 inches in less than a week. Temperatures hit the mid to upper 90s around the same time. After mid February, temperatures were primarily in the 80s, with a dip in late March to the low 70s.

You can read more about Costa’s trail detail in its online publication, which also includes some consumer-friendly features like a personality test that links consumers to their ideal garden.

  1. Those are great locations but none of them gives you information about how plants do in the hot western US. Here in California, our Mediterranean climate means hot and NO RAIN from March through October. That’s a tough time for plants and the more information we all can provide to California gardeners, the more successful they will be and the more plants they will buy

Pricing Tricks Proven By Research

Although there have been very few studies conducted about plant pricing, pricing in general has been studied in just every imaginable way possible. We’ve sifted through some of the most important studies for you. Most of these you’re already using, but some of the other studies may surprise you. The Magic Of 9 Cents This pricing strategy is one of the most famous. We humans tend to pay a lot more attention to the numbers at the left, but not so much to those on the right. So a $3.99 plant next to a $4.00 plant feels less expensive. And since the right numbers don’t register that much, why in the world wouldn’t you get the most pennies you can? If you price your plants at $3.98 or $3.85, consumers don’t care that deeply that they’re less expensive than $3.99. In fact, studies show they’re more likely to buy plants […]

New & Improved: Old-Fashioned Buzzwords Still Motiv…

Connecting with today’s time-starved consumer can be challenging. More things are competing for people’s time, attention and income than ever before. How can you break through all of these distractions to drive sales in your store? The answer may be surprising. It’s simple, it doesn’t cost much in time or money, and the results can contribute significantly to your bottom line. It’s two little words: “new” and “improved.” In a recent Greenhouse Grower column, Dr. Allan Armitage wrote, “’New’ is our lifeline. We had better understand that newness is the horse under our saddle. If it stops moving, so do we.” The idea may seem old-fashioned, but we shouldn’t turn our backs on the power of the words “new” and “improved” in our selling strategies. Even in today’s market, the consumer has a love affair with these important words. Look at Apple, and the platform they’ve built with each next-generation […]

How Your Retail Plant Sales Practices Compare

Editor’s note: Greenhouse Grower RETAILING asked growers and retailers to share their pricing methods in a survey sent out in mid June 2016. Of the 362 responses, 202 arefrom those whose primary business is garden retail. We will be sharing the results of what we learned throughout July, August, and September 2016.   Discounting plants is a finely wielded weapon for plant retailers, Greenhouse Grower RETAILING‘s Plant Pricing Survey shows. It will come as no surprise that just about everyone holds sales at some point (93%). And so it makes sense that some expertise is shown. Take this first graph as an example. The most perishable plants — small annuals and vegetables — are the most likely to be placed on sale. That seems counter-intuitive. Why place the fastest turning inventory on sale? But when we took a closer look, we found that these sales are being used to lure […]

First Five Plants To Win 2017 All-America Selections An…

All-America Selections (AAS) has announced its first five winning plants for 2017. Three of the five are national winners, and two are regional winners. And of the five, one is an ornamental plant, while the other four are edibles. A panel of independent judges selected these plants after reviewing trial performances. AAS says all these plants are available for immediate purchase. Here’s the list of winners: Celosia ‘Asian Garden’ (2017 Ornamental From Seed National Winner). This celosia winning in North America’s trial sites makes it the first ever AAS Winner from Japanese breeding company Murakami Seed. The judges gave this entry high marks in the greenhouse for the good branching, almost bushy growth habit, and early-to-bloom flower spikes. In the garden, ‘Asian Garden’ celosia continued to bloom on sturdy stems, keeping the bright pink color all summer long, holding up even through some of the first frosts of the season. The AAS judges commented on […]

Home Depot Sues Credit Card Companies For Weakening EMV…

Home Depot has decided enough is enough. The mass merchant is suing MasterCard and Visa for colluding on interchange rates, which it claims it enforces through a monopoly, and for watering down the effectiveness of EMV chips by not requiring PINs in the U.S. In the lawsuit (read a PDF of the 140 page document), Home Depot’s lawyers state: “For years, Visa and MasterCard have been more concerned with protecting their own inflated profits and their dominant market positions than with the security of the payment cards used by American consumers and the health of the United States economy. Visa and MasterCard have pushed consumers to use payment card technology that Visa and MasterCard know is defective and subject to fraud and have colluded with each other and with the banks that issue debit and credit cards to do so. They have also unlawfully fixed at high levels the so-called […]
