What perennials are looking the best in your July-August Garden?

I'm looking for perennials that can handle a hot full sun location and still look pretty good in July and August. I don't take comments in perennial catalogs seriously anymore cause they're often inaccurate. Let me know what holds up well in your sunny border. Thanks much.

    Of perennials, phlox and hibiscus add the most color to my garden now.

    July and August is the peak of my back garden, which is planted with almost all native perennials, (except for a handful of exotics). These plants are in peak bloom in July/August -

    Lobelia cardinalis (Cardinal flower)
    Assorted Phlox
    Heliopsis, Helenium, and Rudbeckia
    Echinacea still looks good
    Silphium perfoliatum (Cup plant)
    Assorted Monarda
    Eupatorium/Joe Pye weed just starting
    Agastache foeniculum (including 'Blue Fortune', 'Black Adder', and 'Golden Jubilee')

    Also, a few daylilies are still blooming. And the Buddleia 'Black Knight' is gorgeous. And the annuals are just getting going!

    My favorite perennial bloomer right now is probably the Cardinal flower, there are 3 patches of stunning red spires and the Hummingbirds are in heaven.

    Plumbago, and shrubs like knockout & other roses, cannas, butterfly bush, lantana. The Hydrangeas that were so pretty blue are now a faded but pretty mauve color.

    Summerstar, you didn't mention anything about watering or length of time you gave your plants to settle in before deciding they weren't doing what you want. If you could give a few examples of plants that are doing well, then a few you want to replace, it would be easier to know what the conditions are like. Is the border along your house? You didn't say anything about height or color...

    * Hibiscus are going to start blooming in probably another week - they'll be the stars of the garden through the rest of August.

    * Echniacea "White Swan" and "Magnus" - blooming their pretty little heads off :0)

    That's about it for now other than the annuals - the zinnias are magnificent this year.

    Late July/August are fairly slow perennial-wise for me, but I do rely heavily on foliage effect so beds are still visually interesting if lacking in color. The blooming picks up again come late August/early September when the anemones rev up and the sedums, mums, etc. come into their glory :0)

    Other great plants for Zone 7...

    Echinacea 'Hot Summer' - A must have plant! Stand out beauty! Still blooming in record heat.

    Echinacea 'Pica Bella'
    Echinacea 'Flame Thrower'
    Echinacea 'Pow Wow Wild Berry'
    Echinacea 'Fragrant Angel'

    All of the above, plus my clethras are beginning to flower, and the scented hostas are blooming. The queen mum of all the scented hostas, plantanginea, should be in bloom by the middle of August (also known as August Lily hosta).

    Echinaceamaniac, have you tried Hot lava? What do you think about it?

  • echinaceamaniac
    12 years ago

    I didn't have any luck with "Hot Lava." The Terra Nova hybrids don't do well here, except for "Flame Thrower." "Hot Summer" is amazing though!

  • Bumblebeez SC Zone 7

    Lantana
    Mystic Spires,Indigo Spires and Victoria Blue Salvias
    Sedums
    Walker's Low Nepeta
    Russian Sage
    Spanish Lavender
    Some echinaceas
    Border Blue tall veronica
    Phlox- Light Pink Flame
    Some chrysanthemums
    Various greggi salvias
    Verbena bonariensis

    and believe it or not, a few snapdragons

    Flowering Shrubs that look great right now:
    Knock out Roses
    Limelight Hydrangeas ( I have several paniculata varieties but like Limelight best- I want vanilla strawberry)
    Butterfly Bushes
    Rose Of Sharon- I have Helene- a real beauty and Diana

    Most of my daylilies look like crap but they are blooming.

    In addition to those mentioned above, these are blooming now in my garden:

    agastache rupestris
    Chelone/turtlehead
    liatris/gayfeather
    blackberry lily
    balloon flower
    lobelia cardinalis
    lobelia syphilitica
    buddleia
    snakeroot
    stokesia
    gaura

    The toad lily should begin blooming in a few weeks. For some reason one of my snakeroots is blooming now while the other just a few feet away only has small buds on it so far. The bees love it.

    Whoa!! Did I miss it, or was Rudbeckia missing from all the lists above?. My Goldstrum is almost at peak now with it's parent R Fulgida just getting started. Can't beat them for bright long lasting color in the late summer garden.

    Agastache 'Golden Jubilee' is also great here. I cut it back and it's blooming again a week later.

    Use Annual Zinnias to take up the slack when Echinaceas start fading. I like the scabiosa zinnias. Thompson-Morgan has a nice mix called 'Candy Cane.'

    Sorry about the lack of info. I was looking for a broad range of flowers with no height requirement and interested in those plants that can take the sun and heat and are more drought tolerant. When the flowers are past their bloom, I would be quite happy if at least the leaves hold up and don't go crispy. An example is my Yarrow which is in a prominent place. Its foliage looks awful come the end of July. And I do water when plants absolutely need it.

    The perennial bed in question is in the back of our garden against a fence line and faces south with full sun all day long. I'm looking for those plants that are still looking good in the July-August time frame and thought I'd ask here. I've been introducing many more trouble free plants as I'm certainly not getting any younger!

    So . . . In the past two years I've renewed the bed by adding Goldenrod, the Salvia 'May Night', along with two new 'Ruby Star' Weigela shrubs to give variety to the bed. Last year I added four peonies and two Baptisia 'australis'.

    I have the Veronica 'Sunny Border Blue' which is an okay flower, but I've had them for years and am a little tired of them.

    I second the plumbago. I discovered it last year and it bloomed like crazy into September. It is a tender perennial here in northern VA and I had it in pots, but plan to try it in the garden next year. The blue color is fantastic!

    What's looking best for me right now in the perennial garden are various Phlox including "David", dwarf crepe myrtle, roses, Joe-pye weed ("Gateway"), deep red Lobelia and of course Rudbeckias, especially R. triloba:

    Nice Rudbeckia! I love the dark stems. I need to add this one to my list of plants I want. Thanks!

    Hands down no contest is Rudbeckia hirtas for me. I also have Rud fulgida 'Goldsturm' but it's hidden by the hirtas. They can be a short-lived perennials but they reseed like gangbusters and I have all kind of interesting babies popping up from the cross pollination. They love heat, they don't mind bad soil, and they don't seem to mind droughts, as well.

    I love Rud trilobas, and all the seeds I got last year in trades ended up being Rud hirtas. Got some triloba seeds this year and I am really hoping they are trilobas. They are so cute!

    There's good and bad about Joe-pye weed. I started with one (non-hybrid) plant about 9 years ago and now there are at least 50 scattered around the garden (promiscuous reseeding). One good thing is that they add flashes of yellow to the garden even after going to seed (goldfinches love the seed and I'm seeing them frequently perched on Joe-pye seedheads, enjoying a snack).

    I have been enviously eyeing the pics of echinacea hot summer so was pleasantly surprised to see it in my local nursery. However it looked nothing like the pics posted here. Was just various shades of pink. Whereas the catalog pics look like those posted by enabled. I wonder If there are regional differences to flowering? Anyway glad I didn't mail order it.
