Out of my 38 Austins, the 36 Austins as own-root ARE MUCH SMALLER than rose parks' Austins as grafted-on-Dr.Huey.

Below is a list of 34 OWN-ROOT Austin roses, plus 1 grafted on Dr.Huey for the past decade in my zone 5a & shady garden with heavy alkaline clay & 40" of acidic rain in short summer & 7 months of 23" snow winter.

1) Lilian Austin .. always healthy bought in 2011. Nice scent, killed it due to nasty thorns that poked me when I deadhead the blooms. It's small as own-root in my garden, but HUGE at rose-park as grafted-on-Dr.Huey.

2) Charles Darwin ... healthy but stingy in hot & dry & bought in 2012. Gave away since the blooms fade. Low-thorn & pale leaves.

3) Scepter'd Isle .. healthy & dark-green leaves & gets HUGE as own-root & bought in 2012. Gave away.

4) St. Cecilia .. healthy & compact bush. LOVE ITS fantastic myrrh scent.

5) Wise Portia .. lots of blooms in partial shade, healthy, strong scent in cool weather only. Dark-green leaves & compact growth.

6) Radio Times .. big thorny bush but fantastic damask scent. healthy the first 6 years. Easy-bloomer in partial shade after 10 years. Prefer alkaline soil.

7) Golden Celebration ... healthy the first 5 years but decline as 10th-year own root. Amazing scent but long pause between flushes.

8) Christopher Marlowe ...healthy as 12 year own root.

9) Evelyn. ALWAYS HEALTHY since 2012, tons of blooms .. likes alkaline clay & big and spreading bush.

10) William Morris, best in sandy soil, but NOT in clay, died in its 1st winter & need full-sun.

11) Mary Magdalene: pale leaves & ALWAYS HEALTHY since 2011, super-thorny with frankincense wafting scent. Small bush but TOO PRICKLY.

12) The Dark Lady. Big blooms on compact bush. Bush needs constant fertilizer to stay bushy, otherwise it's a few sticks.

13) Princess Anne. Huge thorny bush, 3 distinct flushes with pausing in between & lots of blooms in partial shade. Not much scent.

14) Pat Austin. LOVE IT even after 10 years. Short pause in between flushes and long blooming. Dark-green but glossy leaves like it wet & alkaline.

15) Lady of Shalott. Huge thorny bush, stingy in partial shade.

16) Crown Princess mag. LOVE it even after 11 years. HUGE BUSH but blooms are gorgeous with best fruity scent.

17) Jude the Obscure. I tried this 4 times as own-roots .. bought it TWICE as own-root, and a friend gave 2 rootings. Most wimpy ever as own-root.

18) Eglantyne. Amazing scent, tried this TWICE as own-root. Stingy & tiny as own-root thus best grafted.

19) Munstead Wood. LOVE it as own-root. Constant bloomer & always healthy. Dense & many thistles but compact bush.

20) Sharifa Asma: LOVE its fantastic scent. This is best in fluffy & loamy soil.

21) Carding Mill: Constant blooming & Need potassium to stay healthy.

22) Queen Nefertiti: Very thorny & need fast drainage.

23) Queen of Sweden: Gave it away, tiny blooms that shatter with zero scent. Tall bush that shot up to 5 feet. Stingy but healthy.

24) William Shakespeare 2000, MOST FAVORITE AUSTIN, most compact & always blooming and MOST HEALTHY, need partial shade.

25) Darcey Bussell: Zero scent & but bloomed lots in partial shade & VERY HEALTHY. Died in poor drainage clay.

26) James Galway: VERY HEALTHY but SUPER TALL in partial shade.

27) Tess of the d'Urbervilles: VERY HEALTHY, nice-red color, needs more sun to bloom than 4 hours.

28) A Shoprshire Lad: WORST AUSTIN EVER AS OWN-ROOT !! Stingy.

29) The Squire: SUPER-THORNY.Dark-green leaves bloom well with alkaline tap-water.

30) Young Lycidas. THIS IS THE ONLY AUSTIN that I have as grafted-on-Dr.Huey, since I could not get it as own-root. Leaves are crinkled like Sharifa Asma and also wimpy & tiny as a plant. It died in its 1st winter.

31) Leander. Has below average ratings in HMF for vigor and cold hardy, but I bought it in 2021 for its scent. Almost thornless, very slow & short growth with cluster roots. Best scent & might not survive this winter.

32) Teasing Georgia. Twice bigger than Leander in growth, but roots stay cluster & can't harden for winter survival. Might not make it this harsh winter with freezing rain in March.

33) Wenlock. CANE HARDY in zone 5a. survives winter (bought last year), low-thorn and I like its scent better than L.D. Braithwaite.

34) L.D. Braithwaite. 2 feet of green cane after winter. Very vigorous. Light Myrrh Scent.
35) Royal Jubilee: strong fruity-rose scent, many blooms but few petals.
36) Sweet Juliet -beige color, wonderful lemon and old rose scent.
37) Noble Antony - wimpy growth but fantastic old rose scent. 
38) Eustacia Vye (grafted-on-Dr.Huey) - blackspot prone, but the blooms are gorgeous with a great scent. Bloom well in partial shade.

StrawChicago in zone 5a with dense alkaline clay, 38" to 40" of heavy acidic rain in short summer, but drier winter, and flash floods in spring.

Re-post the info. from Antique Rose decade ago, with my notes followed each:

"Rosa Moschata (5 votes, scent that spread across 100 yards) & Sweet Eglantine (strong leaf-scent & spicy)

Darlow's Enigma (6 votes, zone 4b hardy & shade tolerant & thorny)

Secret Garden Musk Climber (3 votes & thorny & clove & dianthus scent & hardy & continuous blooming)

Bubble Bath (scent that spreads the entire garden, doesn't bloom much for hot & dry CA)

Marie Pavie (3 votes) & Sweet Chariot (2 votes) & Lavender Lassie (1 vote)

Jacques Cartier (3 votes from loamy & fluffy soil folks). I had an own-root Jacques Cartier in a fluffy potting soil and the bloom was intensely fragrant.

Comte de Chambord (2 votes). When Comte is blooming, the perfume is in the air 6 feet away. Few blooms of Comte are enough to perfume the entire room, same with Firefighter.

Perle d'Or (2 votes) One bloom of this polyantha is enough to perfume the air with its heavenly scent. To my nose it smells 10 times better than Gardenia.

Paul's Himalayan Musk (2 votes, very large climber, once-blooming, zone 4b hardy)

Jaune Desprez (2 votes, tea-noisette, NOT cold-hardy, wafts 50 feet)

Zepherine Drouhin ( 4 votes & thornless & wafts 20 feet) & Great Maiden Blush (1 vote)

NOT A ROSE, but Sweet Autumn Clematis is mentioned as wonderful wafting scent. Gruss an Coberg & Lemon Spice & Papa Meilland & Young Lycidas & Grandmother's hat get the most votes for best-quality & addictive scents." From Antique Rose Forum many years ago.

I'm in cold zone 5a, Chicago suburb. Some of my OWN-ROOT winter-hardy roses (down to -20 F) also match KBW's most heat-tolerant roses (up to 113 F in Pakistan). To survive drought & heat & cold, an own-root rose needs to have deep & vigorous root. It took me 2 days to compile this list of most VIGOROUS roses with LASTING BLOOMS THE VASE.
