‘Westerland’ shrub rose just keeps sending out new sprays of blooms.  EB

Summer is here, and we have reached the middle of the month when I encourage each of you to walk around your garden and assess what you need to add to make this season an exciting time in your landscape.  This time of year I like to focus on the “energizer bunnies” of the garden: plants that bloom or rebloom from late spring through fall. Plants in this category will have “EB” following their caption description.  They give me a reason to stroll in my garden when the weather is not as inviting as spring.  Make sure your garden doesn’t end with the spring rush by adding plants that bloom through summer. 

I love irises, and I think Japanese iris, I. kaempferi, is my favorite.  The colors and the flower shapes are magical.

Make a list and take photographs so that when you are shopping for plants you know what you need and where it should go.  You never know what you might find waiting in your garden like new blooms on my ‘Westerland’ rose (photo at top), which I photographed during my own  inventory.

The remontant or reblooming daylilies are some of my “bunnies”.  They start early and rebloom all season.  Clockwise from left: Hemerocallis ‘Black Eyed Stella’, ‘Stella de Oro (d’Oro)’, and ‘Happy Returns’.  EB

July 15 is Garden Blogger’s Bloom Day for July when gardeners around the world show photos of what’s blooming in their gardens (follow the link to see  photographs from other garden bloggers assembled by Carol at May Dreams Gardens).  Here are  some more highlights from my July stroll through Carolyn’s Shade Gardens, starting with woody plants:

I cut back my ‘Purple Robe’ smokebush, Cotinus coggygria ‘Purple Robe’, every year to improve the leaf color so it never blooms, but I think the red beebalm, Monarda didyma, compliments it nicely.

My grove of native bottlebrush buckeye, Aesculus parviflora, is stunning in bloom in full shade.

St. John’s wort is a woody subshrub that I cut back almost to the ground in the spring when I see signs of new growth.  Hypericum calycinum on the left and H. androsaemum ‘Albury Purple’ on the right.

I don’t grow ‘Winterthur’ beautyberry, Callicarpa ‘Winterthur’,  for the flowers, but between the lime green leaves, the pink flowers, and the striking light purple berries in fall, this shrub is a workhorse.  EB

Himalayan leptodermis, L. oblonga, starts blooming in June and doesn’t quit until later in the fall.  Its flowers are small but abundant.  EB

‘Black Knight’, Buddleia davidii ‘Black Knight’, is my favorite butterfly bush cultivar.  It is the first to come into bloom in June and doesn’t stop until at least mid-fall.  EB

My native honeysuckle vines are still throwing out blooms after a spectacular spring show, here Lonicera sempervirens ‘John Clayton’.  EB

And here native Lonicera sempervirens ‘Crimson Cascade’.  EB

Native oakleaf hydrangea, H. quercifolia, will keep going until winter with its beautiful flowers turning colors and then forming a dried arrangement.  If you don’t have this shrub, it should go to the top of your list!  EB

I am surprised that more gardeners do not grow native flowering raspberry, Rubus odoratus.  It is a gorgeous tropical looking shrub for full shade with brightly colored raspberry flowers.  The native bees love it.

There are so many perennials in bloom that I had to leave a lot out.  I am focusing on the unusual plants and the ones that bloom for a long time:

The deep violet flowers on red stems of ‘Caradonna’ sage, Salvia ‘Caradonna’, continue to rebloom all summer while the yellow corydalis, C. lutea, behind it blooms nonstop from April to December.  EB

This rare and unusual plant, Chinese foxglove, Rehmannia elata, appeared in my rock garden without my help, but I am glad it did.

Butterfly weed, Asclepias tuberosa, with catmint, Nepeta ‘Walker’s Low’

Many hosta have quite beautiful flowers, especially if they are compact and white, here the species Hosta tokudama.

Reportedly there are 8,000 hosta cultivars, but some just stand out in the garden: Hosta ‘Summer Lovin’

The gorgeous corrugated blue leaves, white flowers, and elegant habit of Hosta ‘Blue Angel’ have stood the test of time.

Hosta ‘Great Expectations’ is also a classic with white flowers.

I am infatuated with the mouse ears series of miniature hostas, and one of their wonderful attributes is that their flowers are compact and proportional to their size, here ‘Holy Mouse Ears’.

I have tried so many of these orange coneflowers, Echinacea cultivar,  only to have them die, revert, or display a virus.  This is the only one that survived and, of course, I lost its tag.

‘Concord Grape’, Tradescantia ‘Concord Grape’, is my favorite cultivar of US native spiderwort.  I cut it to the ground completely after flowering to rejuvenate the plant.

Giant ox eye, Telekia speciosa, is an unusual sunflower-like perennial that reaches 4 to 6 feet tall and 2 to 3 feet wide in the full shade of my London plane trees.

Solitary clematis, C. integrifolia, just keeps blooming and blooming, here with orange million bells, Calibrachoa ‘Aloha Hot Orange’.  EB

I always read that the groundcover autumn leadwort, Ceratostigma plumbaginoides, blooms in the fall, but in my garden it starts in June and keeps going through fall.  You can’t beat the true blue color all season.  EB

I have a collection of hens and chicks, but I think this is my favorite: Sempervivum arachnoideum ‘Red Cobweb’.  When not in bloom, the chicks are red and covered with cobwebs.

This is the second flush of bloom on ‘Sarastro’ bellflower, Campanula ‘Sarastro’, the first flush has double the flowers.  I have tried several large-flowered bellflowers, and ‘Sarastro’ is the best.  EB

I devote a large space in my meadow (you have to, it spreads) to beebalm, Monarda didyma, the flowers are so spectacular.

I always let some of my onion sets get away from me so they will produce this beautiful flower after all my other alliums are done.

If I had the right growing conditions for red hot pokers, Kniphofia ‘Alcazar’, I would have every cultivar, but sunny, hot, dry, well drained conditions are few and far between at Carolyn’s Shade Gardens.

Spiny bear’s breeches, Acanthus spinosus, just keeps blooming and blooming.  EB

I will leave you with the very unusual and long lasting  ‘Miss Willmott’s Ghost’ sea holly, Eryngium giganteum ‘Miss Willmott’s Ghost’.  Miss Willmott was a 19th century English gardener who secretly sprinkled seeds of this sea holly in gardens she visited leaving behind her “ghost”.  EB
