What's in Bloom?

 

There are always clematis blooming in the garden! See below for a complete list of this week's blooms, plus a map to help you find each theme garden and bed number. 

Errata: on the map above, Beds 6 and 7 are switched. Bed 6 rounds the corner of the farmhouse to its west-facing red cement porch. Bed 7 is across the path and runs along the old wire farmhouse fence.

Excellent late bloom and rebloom! September 1, 2026

We have 148 varieties and species still in bloom or back in bloom! As we progress through September, more and more of the clematis pruned in late July and early August will rejoin the later blooming species and hybrids, so that number of clematis in bloom may stay steady through the month.

For those of you on Facebook, look for us at Rogerson Clematis Garden. We’re on Instagram at @rogersonclematis as well as Rogerson Clematis Garden.

Visit CLEMATIS SALES: ON-SITE and ONLINE sales are open! Shop with our trained volunteers or pick up online orders Mon/Wed/Fri/Sat from 10am-2pm.

Also, for a more detailed response, or to send photos for clematis identification, please email info@rogersonclematiscollection.org

In Bed 11 of the Heirloom Garden beautiful ‘Blue Bell’ threads through the old garden rose ‘Stanwell Perpetual’, which is continuing to bloom in a random manner.

West of the Greenhouse and our Sales Terrace is the Mt. Cuba Area, where newly documented vining species of the Viorna (summer bells) Group of clematis are displayed. This is Clematis cumberlandensis.

The shrubby clematis are thriving throughout the garden. This specimen of ‘China Surprise’ forms part of the colorful underskirt for The Egg.

Sometimes putting something unusual in a container makes a feature of it. This is Clematis aethusifolia, a rarity in cultivation, doing really well in a container until we figure out where to plant it in the ground. It is in the Container Display Area.

OTHER PLANTS

Volunteer Robin Sonoda used the whole garden to create a floating tribute to Dolly Parton. Included are Dahlia ‘Sellwood Glory’, florets from a dwarf Hydrangea, roses from ‘Jayne Austin’, Lilium speciosum var. rubrum ‘Uchida’, Amaryllis bellamosum (belladonna lily).

the Modern Garden

At the end of each row along the center aisle is a modern non-climbing hybrid or very short-growing vining cultivar.

In the Modern Garden we celebrate the streaked and striped clematis in Rows 15-16. This is ‘Galaxy’, an American selection of a sport of ‘The President’. Row 15.

BED 4

This is one of our largest beds, starting across the paths from Bed 3 and Heirloom Garden Bed 5, continuing along the west boundary fence of The Antipodes beds, and the gravel path towards the chicken coop. Step down to the greenhouse level and walk back toward the farmhouse, which will end the Bed 4 loop.

‘Shizuku’, ‘Edomurasaki’, ‘Haizawa’, ‘Fuyu-no-tabi’, ‘Odoriba’ (two plants in separate locations within this bed), ‘Roguchi’, Clematis terniflora (sweet autumn clematis), ‘Alba Chirifu’

‘Edomurasaki’ always gives its best show in the autumn. It wants to get tall before working on flower buds.

Coop Border

This adorable pair, both non-climbing clematis bred by Kazushige Ozawa, have been bloom all summer, and have finally crept into each other to charming effect.

Along the west side of the chicken coop and run, this bed faces due west, so the clematis planted here are sun-lovers, along with their herbaceous perennial companions.

C. integrifolia ‘Ozawa #1’ “Big Blue”, ‘Yufune’, ‘Watayuki’, ‘Little Belle Sumire’, ‘Shikon’, ‘Utsusemi’, ‘Oborozukiyo’

Clematis ‘Shikon’ has a unique form and a wonderful sky blue color. It is a non-climber. It was hard pruned in May, and has stayed compact.

Entry Border

Reblooming tall bearded iris ‘Rosalie Figg’ has a new partner this year, shrubby clematis ‘China Surprise’.

‘China Surprise’, ‘Natalie Cottrell’, ‘Pink Flamingo’ (in urn), ‘Esprit’ (in urn), C. fruticosa ‘Mongolian Gold’ (in southernmost urn)

This new feature of the Rogerson Clematis Garden is a long perennial border opposite the Coop Border. It begins with an anonymously donated metal arch with waving stems of reeds on which large-flowered hybrids climb, greeting visitors with that which they expect to see. But beyond the arch are the other forms of clematis most people don’t know about. Large flat panel trellises are populated by clematis that get big. They are fronted by clematis that cannot climb, in all of their wonderful colors and flower forms. A series of urns house draping clematis from the Atragene section (this is the section with C. macropetala and C. alpina, among many other species), which start flowering in April and repeat bloom through the summer. We have some woody shrub clematis here, too! Into all of this celebration of the variation within the genus Clematis, we have added an array of herbaceous perennials from groundcovers to tall summer-blooming plants, including lilies and repeated stands of Celtica gigantea (syn. Stipa gigantea, stipa grass). We have carefully selected a few shrubs into which the non-climbing clematis may loll if they choose.

Our experiment with draping clematis out of display urns has not been entirely successful, but ‘Esprit’ is happy and understands the job.

The Front Bank

BED 14

‘Zoqum’ QUEEN MOTHER, ‘Pagoda’,’Hendryetta’, ‘Titipu’, ‘Gravetye Beauty’, ‘Genie Brannon’

What is a shale barren? Thousands of years ago, Virginia was underwater. As the inland seas retreated, the layers of compressed silt formed these massive walls of quite fertile crevices, if you have roots that know how to exploit the nutrients. The little mounds of green at the upper right and at the bottom of the shale scree are clever Clematis coactilis.

The Baltic Border

Clematis x diversifolia ‘Olgae’ is back in full bloom after being uncerimoniously beheaded to supply the spring propagation class. It was bred in Ukraine when that country was within the USSR.

Winter Bloomers

Inside the Sales Terrace, these clematis are growing on 4’ wide by 10’ tall flat panel trellises. During the winter when we have volunteers on hand (Monday/Wednesday/Friday from 10-2), the gates to the Sales Terrace are unlocked for easier viewing.

Subtropical Shade Porch

All specimens have been moved outside.

The Antipodes

The unique clematis native down under, in Australia and New Zealand, have many unique attributes. Even Australia’s island-state, Tasmania, has a clematis all its own. Here you will find the world’s smallest clematis (C. marmoraria), as well as a clematis with no leaves (C. afoliata). This quadrant of the world is often referred to as The Antipodes, meaning the ‘opposite’.

Nothing in bloom

Mt. Cuba Project Area

Clematis cumberlandensis was given species status in the 1880s, but later lumped into C. viorna. DNA analysis has reestablished it as a species in its own right.

Rows 1-3, foundational species and those not covered in the Estes et al study: C. beadlei, viorna, crispa (from Horning seed), C. pitcheri (Texas), C. versicolor (Tennessee), C. pitcheri (Austin TX area), C. vinacea. Rows 4-9 newly documented species: C. arenicola (Texas, Arkansas, Louisiana), C. flaccida (Alabama, Georgia, Tennessee), C. ouachitensis (Arkansas, Oklahoma), C. ozarkensis (Arkansas), C. subreticulata (Alabama)


CONTAINER DISPLAY AREA

Two planters with swirled metal supports contain clematis ‘Mrs N Thompson’ and ‘Evipo097’ KITTY, seen here showing off its clean little white flowers. Container Display Area

This area, between the Bob and Carol Gutmann Greenhouse and The Antipodes will be increasingly populated by a display/demonstration area for growing clematis in containers. We imagine a continually changing, slowly evolving space where those with small gardens will find suggestions and inspiration. Seating is coming soon, too! The broad pale green bowls in the container area often have floating arrangements of clematis.

The Egg

‘Vitiwester’ (syn. BURNING LOVE), ‘China Surprise’

The Egg has undergone a major replanting to remove Agastache ‘Little Adder’, which ran amok. The more refined cottage garden plants return, along with the hybrids and species selections of the late Ton Hannink of Holland, a past president of the International Clematis Society. What better memorial to the man than his plants?

Artist James Harrison donated a handsome structure he created using the proportions of a Fabergé egg; hence we call it The Egg. It occupies the round foundation of the long-gone Luscher Farm silo. The cottage garden herbaceous perennials and volunteer annuals (the sunflowers are full of American Goldfinches nearly all day, every day) make a mad display at the feet of the clematis climbing The Egg through the spring and summer.

Mr. Western Bluebird is a frequent percher on The Egg, reminding humans that the mealworm feeder is a thing that exists and always needs replenishing.
