balling hybrid perpetuals
Comments (7)Hi Aimee! Nice to see you've been able to pry yourself away from the cribs! Do your sprinklers hit the flowers on those roses? If not yours, are there any on the HOA common areas around your back yard which might be blowing in over or through the back fence which might hit them? I have several friends with that issue. THEIR sprinklers are adjusted not to hit the tops of the roses, but the HOA rainbirds on the common areas over shoot and drench their roses, causing all sorts of issues. High heat and scalding sun can fry those soft petals. Dews and cool, damper temps can also cause balling. I doubt fertilizing them, or not, is going to result in any improvement because the soft petal tissues will still react to both damp/wet and searing heat and sun the same way. I replaced most of the HPs and Bourbons in the old Newhall garden, not that many miles from where you live, because in that climate they just didn't perform well. When there were flowers, they didn't stand up to the severe conditions, and when all the more modern roses were exploding, most of those just sat there. I was in Old Orchard, Valencia today. Souv. de la Malmaison's blooms were all balled. The sprinklers do not hit them and I am the only one who uses a hose anywhere near it. Souv. de St. Anne's across the path from it were all fine. Yves Piaget's flowers, right beside Malmaison, were fine. Larry Daniels' flowers just on the other side of Yves, were all fine. There are just too many, too thin, wispy, tender petals to endure the sun and heat intensity this time of year. Kim...See MoreHybrid Perpetuals for a Mediterranean garden
Comments (24)Hi Melissa, Most of my roses are Old Garden Tea or Noisette roses, but every now and then I get a craving for the scent of a damask rose and head to the H.P. section of a catalog. In our area of Oakland, California, the conditions are the worst for the spread of 1. powdery mildew, all through spring and much of Autumn. 2. followed by blackspot which doesn't show up until early summer when temperatures rise. Then we have 3-4 months of drought and unless foliage is watered, foliage disease isn't much of a problem until the rains begin in Autumn, and p.m. and blackspot return. The native soil is heavy clay. Of all the H.p.'s I've planted in my own no-spray and public rose gardens these were the healthiest, by far. Top 5 H.P.s for disease resistance where I live: 1. Baronne Prevost' Extraordinarily fragrant, too. 2. Mrs.John Laing'. a pretty plant, but has bare ankles which I surrounded with heritage geraniums from the 1800's and earlier. 3. Comtesse de Chabrillant' a real sweetie, bears darling smallish rounded pink roses, on a pretty plant, whicj is spreading and leafy. Very disease resistant where I live. 4. Grandmothers' Hat' grown self standing which makes it re-bloom more often, and as a climber. also benefits from under plantings to hide bare lower canes. 5. 'Mme. Boll' the most upright of these, which is not my favorite growth habit. I also grow 'Frau Karl Druski' because I love white roses, and she is one of the whitest rose I have ever seen, I also like her scent, light but clean and fresh smelling. Foliage is clean until it rains or I get careless and sprinkle her foliage during the few weeks it gets hot enough here for rust to show up. I came across a 'Grandmothers Hat' that was thriving in an abandoned garden where it hadn't been watered by anyone for ten years or more. As I mentioned we get reliable summer drought for months on end. It was growing in deep shade which is probably why it survived the long droughts, and I was delighted to see pink roses near the top of an evergreen tree!!! An H.P. that can survive drought and bloom despite being surrounded by evergreen foliage, 'Grandmothers Hat' would be my top choice if I had your conditions. Luxrosa P.S. These failed and were removed: 'Gruss an Teplitz' from powdery mildew. 'Monsieur Boncenne' rusted to death....See MoreGrowers of Sophie's Perpetual -- questions for you
Comments (13)Virginia, Alana, and Mzstitch, thank you for your suggestions--these are very helpful. Virgina, Perle d'Or has been high on my list for sometime. I like it and think it will do OK here. Clothilde Soupert--I think I had ruled that one out after reading of likely problems with it. One strategy I'm using is to see which roses people in *warmer* coastal climates here say they are having problems with because of wet or cold. Because here I have the wetness but much less sun, so they surely won't work for me. I will look into the fragrant Chinas, as you suggest. Alana, several months ago I had the chance to pick up an Excellenz von Schubert at a small local nursery. The nurseryman there suggested it to me, and I wish I'd taken the tip. They don't have it anymore, but I'll consider ordering it. Mzstitch, my Sophie's Perpetual is about 3 yrs old and about 2' x 2' and lives in a pot that's maybe, oh, 2.5 gallons? And she is also blooming her head off right now, which is incredibly gratifying to me. She is my first real rose success. I'm actually happy with her slow growth, because of my limited space. I hope she'll gain another foot or so, but I'll be happy if I can maintain her in a pot. I really love this rose and her beautiful fragrance. I've just started trying to propagate some cuttings, my first attempts at this. If I can find other roses that have similar requirements to Sophie's P., I'll be very glad. My few other roses *are* budding right now (hooray!), so maybe I'll find more varieties that can succeed in my space. I would love Souv. de la M., but I believe that I read about problems with cold or damp from people living in warmer coastal areas. I'll check again, also K. Victoria and Borderer--thank you....See MoreHybrid Perpetuals + hot, humid summers = bad combo?
Comments (72)Perle's scent is very light. Her apricot blooms fade more quickly in sun, but they are charming either way. Perle is quite thorny and grows into a substantial bush. In its shadier location, my Perle can easily top 6 feet even when pruned regularly. Her buds are like tiny high centered Hybrid Tea buds. She is very healthy. Like Marie, Perle blooms late spring through fall. Something else to note about Marie Pavie: she's thornless. Carol...See Moreiliketoast
