I have the Heger/Whitman book, but I find the information cumbersome and the book is so big and heavy. It's great for research at home, but one thing I love about the Engebretson books is their portability. They are easy to keep in the car (and have durable water-resistant covers) and they'll even go in a medium size purse. Hey hostaholic.... we should meet at the Arboretum again! Mia will be 5 this summer! You'd hardly recognize her!

I have Sara Williams' book Creating the Prairie Xeriscape and agree with you that it is an excellent book, and not just for those on the Prairies. I live in southern Ontario. Another good one that I bought several years ago is Growing Perennials in Cold Climates by Mike Heger and John Whitman, two gardeners in Minnesota.

Below is the info. that Floweraremusic (zone 5) in Washington gave on her 2020 winter-survival. She has alkaline clay with rocks at bottom like mine & less snow in winter: "My hardiest roses are the Canadians. John Davis, John Cabot, Wm. Baffin, Morden Sunrise, Morden Blush and Morden Centennial, Victorian Memory aka Isabelle Skinner, also a Canadian rose. All these only have tiny bit of tip damage and bloom a lot with no special care. Also, my Hybrid Perpetuals only have tip damage after winter. Magna Charta, Mrs. John Laing, Black Prince and Marchesa Buccella. The only negative is they don’t have long enough cutting stems. All my Austins are very hardy. The one I just can not grow is Jude. Leonardo da Vinci is super hardy and always healthy. Quietness comes through winter very well. Even Rouge Royale survives beautifully. Cinderella Fairy Tale is very hardy. Gruss an Aachen also. Ballerina and Marjorie Fair are both hardy. Poseidon, Princess Charlene de Monaco and Crazy Love didn’t do as well as I’d hoped. The surprise losses this year are Quicksilver, and Dames de Chenonceau who is left with only 1 cane. Versigny is also reduced down to almost nothing. This was a mild winter with very little snow. " Floweraremusic (zone 5). From StrawChicago (zone 5a with hard black-gumbo alkaline clay & less snow but with freezing rain in winter). Versigny didn't survive winter either. So I lost Versigny TWICE. Besides Versigny, other wimpy own-root roses that don't survive winter well: Paul Neyron, Anna's Promise, Pink Peace (own-root died 1st winter, but grafted-Pink Peace survives many winter), Elantyne, Jude the Obscure, Young Lycidas (bought as grafted-on-Dr.Huey, now with only one cane), Mary Daly, and many floribundas don't survive my zone 5a: Pink Chiffon, Sheila's perfume, King Arthur, Deep Purple, Shocking blue, Honey Bouquet (survived 1 winter). Polka Climber (survived 1 winter), Cloutilde Soupert (died twice on me). Sutter's Gold didn't survive winter, same with many fragrant mini-roses from Burlington nursery. Below are my hardy OWN-ROOT roses in my zone 5a alkaline clay, only Double Delight, Young Lycidas and Lavender Crush are grafted-on-Dr.Huey. Bold-faced are the very vigorous ones: Own-roots with 3 feet of green canes: Carding Mill (since 2012), Princess Charlene of Monaco, Duchess de Rohan, Crown Princess Magareta (since 2012), Zepherine Drouhin, Lady of Shalott, James Galway, Lavender Crush, Queen of Sweden (gave away but very hardy), Poseidon (right below the rain-spout, dug down to 2.5 feet), Scepter'd Isle (very big & hardy own-root but gave that away with its lousy scent).

Bayes Blueberry (survived many winters but I gave away), Charles Darwin (gave away since it fades badly), Arthur Bell (since 2012 & killed it since I don't like the flowers). StrawChicago.

Tonight is the last predicted night under 40... so tomorrow I finally get to pot up the peppers into their containers to put out in the solarium for a week or two to establish before they go outside. The solarium is usually a good 10 degrees warmer than overnight temps. Unfortunately, I used up the last 8 seed of the Farmers jalapeno in a second planting round and none of them sprouted. I only got 1 out of the first 5 seed I planted. Last year I tried growing them and that seed batch failed too. I think I got a bum seed packet. I got it from Tradewinds along with a few other peppers, and all the rest of the seed from them germinated great last year and this year. Also from them I'm trying Trinidad Perfume again- last years peppers were so flaming hot I wasn't sure if the packet was mis-labeled or if it was due to plant stress, so I'm trying them again this year. And I do mean flaming- I was expecting something a bit milder than a jalapeno or hot cherry, and instead they were about as hot as my peach habaneros. Anywho. I had a cat-strophe, so now I'm down to 24 plants total. Still a few more than my original plans of 15-18, but not too many. I have the pots and potting soil for it, and the space- though it maxes out my container space.
