Phlox paniculata 'Peacock White' (garden phlox) is still going strong well into September. What a terrific perennial for attracting bees (see above!), butterflies, hummingbirds, and other pollinators. They also tolerate deer activity, and can grow under Black Walnut trees. It grows to about 4’ tall and 3’ wide, and has a stunning plume of white blooms starting in July and going through September. It likes sun to part shade the best, and needs watering throughout dry spells. The species is native to the eastern U.S.
Heliopsis helianthoides is one of our favorite plants at the end of summer. This perennial native does great in dry soil, clay soil, and rocky soil. The oxeye (or false) sunflower prefers full sun, of course. If you deadhead them, the bloom season will be extended all the way through the end of the summer (and it starts blooming in June!). It gets to be about 3.5’ tall, is a wonderful cut flower for your indoor arrangements, and attracts butterflies. What’s not to love here?

Perovskia atriplicifolia ‘Little Spire’ is a compact cultivar of the species. This plant needs good drainage and full sun. Think of it as an herb when determining plant site and conditions. If there’s poor drainage, it just won’t make it. It’s common name is Russian sage and the greyish-green (and square - it’s in the mint family) stems have a delightful aroma when crushed (and sometimes even not when crushed). The two-lipped tubular flowers present a real show both from afar and up close from June all the way through frost. This perennial is a great addition to your full sun perennial garden or herb garden.
Salvia guaranitica ‘Black and Blue’ is still one of the most popular salvias, and it’s really easy to see why. Salvia guaranitica is a tender perennial that is hardy in zones 8-10. In the Philly area, it’s planted mostly as an annual, and if it comes back next year, it’s just an added bonus. If you really want it to come back, make sure it’s in a protected area and mulched prior to winter.
This foliage is both fragrant (the common name is anise-scented sage) and attractive. The plant needs full sun, and will grow 2-5’ tall. If you want to keep the plant full and shorter in stature, make sure it’s in full sun and you can also cut it back the stems in late spring. Deadheading these will encourage more of the vibrant cobalt blue flowers with black calyces to rebloom from mid summer all the way through fall.
Phlox paniculata 'Jeana' is a great phlox if you’re looking for powdery mildew resistance. This perennial is great for the back of your border at 4-5’ tall. It has lovely pinkish lavender blooms starting in the middle of summer and lasting all the way through fall. It attracts a ton of pollinators, including hummingbirds. It needs well-drained soil, and full sun.
Rudbeckia subtomentosa ‘Henry Eilers’
A different species and cultivar of Rudbeckia offers us a very new look for the garden. This 3-5’ tall plant looks very much like Rudbeckia subtomentosa, but the rays are actually rolled up into tubes, rather than flat. From afar, it has the appearance of quills. This is a very unique and interesting perennial to easily add to your property.
Rudbeckia fulgida 'Blovi' VIETTE'S LITTLE SUZY is an extremely floriferous, smaller black-eyed Susan cultivar. A member of the Aster family, the flowers resemble daisies with dark centers, and rebloom continuously from July till October. It attracts butterflies, tolerates deer, and needs full sun. This perennial is another great one for your rain garden, pollinator garden, or border where you’d like these to naturalize.
Pycnanthemum muticum, mountainmint, is a native perennial that is very easy to grow. It loves full sun to part shade conditions and blooms from July to September.
It spreads through its rhizomes and can be vigorous, but not invasive. You can root prune these in the spring if you want to keep them contained. They grow 2-3’ tall with 2’ spread.
It’s deer resistant and attracts a wide range of native pollinators. This is a great addition to your rain garden, perennial border, cut flower garden, and pollinator garden.
Achillea 'Apfelblüte' APPLEBLOSSOM is a lovely summer flowering perennial in the Aster family. It performs best in full sun, and in drier soils. It flowers from June through September, attracts butterflies and can tolerate some deer traffic. This is a great addition to the front of your perennial border.
Divide this plant entirely every 2 to 3 years. Deadhead the spent blossoms. And when the plant starts to look leggy and unattractive, cut it back to its basal foliage. Depending on the timing and the weather, the plant may produce a second, fall rebloom.
The plant is used medicinally to stop bleeding, and the Genus was actually named after Achilles of Greek mythology because he used it to stop the bleeding wounds of soldiers during the Trojan Wars.
Hypericum calycinum, St. John’s wort, is a versatile woody, deciduous shrub/groundcover. This plant is particularly great on sloped areas that are tricky to weed and hard to grow grass on. It can tolerate a wide range of soil types, and is happiest in full sun. The bright yellow flowers bloom in July and August. Cut this back every 2 or 3 years in late winter/early spring to keep it looking full and flowering well.
Franklinia alatamaha, the Franklin tree, is native to Southeastern U.S., but has a special connection to Philadelphia.Read More

Plant Profile: Vitex agnus-castus
Vitex agnus-castus, Chaste Tree, can be pruned into a shrub form, which is what you see here. It is a prolific summer flowering shrub and is a huge attraction to butterflies. It needs full sun, and we cut ours back to the ground every early spring to keep a tighter, more compact form. It is also considered deer resistant. The blooms resemble Butterfly bush slightly, but the foliage is decidedly more palmate.
Vitex agnus-castus Daytona Heat™ 'Dale White' is a compact, rounded, white version of the shrub. It also loves the full sun, and attracts butterflies just as much, but the white flower offers a more subtle interest in the garden. This plant requires less maintenance and pruning because of its natural tendency to be compact and rounded.
Both are great additions to the perennial border, foundation bed, and pollinator garden.
Plant Profile: Echinacea ‘Pow Wow White’
This is a white flowering coneflower that makes a terrific cutting flower to bring indoors. It also works really well as a dried flower in arrangements. This perennial is happiest in full sun, but can handle droughts, poor soil, and the heat and humidity that we live in all summer in southeastern PA. It’s about 2.5’ tall and doesn’t need to be staked, which is a huge plus. It also reblooms from spring until around the first frost. It’s a terrific addition to your perennial border.
Watering plants may seem straightforward, but it’s easy to do it wrong. We’ve taken the guesswork out of how to properly water your new garden installation (including containers!) in our new how-to video. Let us know what you think of it!
Clematis texensis is a truly adorable flowering vine. This clematis grows 10 feet or longer, and flowers only on new wood. Commonly called Texas clematis or scarlet clematis, the flowers are bell shaped and pink/red and can bloom all summer long, until the first frost. This is a terrific vine to train on a trellis, arbor or mailbox. It can also make a nice accompaniment to scramble over evergreen shrubs or large rocks. Prune this clematis back hard (8-12” from the ground) at the end of the winter or early spring.
