Plants Beating the Heat


Orange Diascia planted in Spring comes back in Fall. The Petunias carry through Summer.

What is happy and still blooming? Not as loud and lively as August except for some isolated patches near the Rudbeckia, the garden tones down to more subdued for September.

Finding plants to stand up to continuous heat, humidity and the run of dry weather is one tough nut to crack. Yesterday, we got a two-minute downpour, typical of how rain has been coming this summer. It did bring temperatures down from a high of 90° earlier this week though.

Many perennials carry their weight in dry conditions, but are usually short blooming. Some like the asters, Perovskia, meadow sage, and Coreopsis are exceptions, blooming for long periods or reblooming.



You just saw my profile of Caryopteris, a small, late-blooming, flowering shrub. It is a perfect choice to carry color into Fall.


Annuals are a real plus to gardens facing dry conditions. Annuals reliably bloom well into Fall if the weather stays warm. Petunia, verbena and Million Bells are wonderful plants for dry areas and will spread the color all season long.


Mixed with perennials, a garden keeps colorfully blooming. Why the push to dismiss annuals in preference to perennials for water conservation and low maintenance? Some annuals have needed little supplemental water unless in hanging baskets.



How do you feel about mixing it up? Just as trees and shrubs are used to span seasons, the annuals help pull a garden through dry spells if chosen well.


Look at the bloom in August and compare it to September. The annuals were in the garden, but so many perennials were in full flower, the annuals were barely noticed.



A few very long blooming perennials…



My garden is small, but mixing it up adds a lot of seasonal and visual interest. Some of the annuals grow from seed every year, like shown above. Each year the Alyssum makes a large patch with a few Ageratum flowers mixed in with volunteer Petunia.

Annuals can be bought early July for pennies, and popping them in where you see a perennial done for the year helps keep a garden blooming. I don’t have many annuals, but it is enough to keep my camera clicking.


Perennial Butterfly Weed and Scabiosa make a cute couple, both rebloom.

    I love all the colors you have displayed here. Gardens just take me to my happy place. Thank you. ; )Alesia

  3. Wow, it looks to me like you still got quite a bit going on in your garden. I have some of the same flowers and after August’s triple digit heat they are fried and look nothing like yours. Enjoy. Blessings, Natalie

  4. I quite fancy cottage gardens so I love the lush wonderful colors in your August-September photos. The photos are so enjoyable.

    Love the colors!! Kudos~

  6. Ah, Donna, this explosion of colors… It’s as if those flowers are saying: “look at us, aren’t we beautiful? Look at us graciously bloom…” They all seem very happy mingling with eachother. A harmonic mix! 🙂

    I agree with your comment about annuals Donna. Some do withstand drought, my Miriabilis jalopa Marvel of Peru has looked really good this summer. (It has been hot over here too). My phlox have lasted well this year like yours – but some of my phlox are late flowering varieties. Herbaceous autumn anemones are looking very good this year in the UK

  8. Looking good! Your gardens are beautiful in the summer heat and the perennials and annuals another beautifully! It has been cooling down here on Long Island in the past week and some of the plants are breathing a sigh of relief!

    That is the most alluring shade of orange!

    wonderful flowers! 🙂

  11. I love the annuals for long blooms and many are planted for my veg garden…others for prized containers. We are due for an early frost…a month early this coming week. The annuals will be lost.

  12. Your garden looks great. You would never know that you have had such bad summer weather.

    It was such strange weather last week! It was 93 degrees and then 70 the next day (which is much better). Your garden looks beautiful in September!

    Here,in Florida,we’re just starting to buy our annuals.Some of which can,sometimes,hold on to become almost perennials.Having grown up in Niagara Falls,I miss the flowers that grow up there,but I have fallen in love with the tropical garden.And I don’t miss the snow!

    Gorgeous color in your garden.
