Exclamation London Plane
Comments (21)I'd love to see it, whaas, I've always shyed away from Platanus despite the fact I love them - the P. occidentalis due to the horrible anthracnose most get here, and the P. x acerifolia due to the rusty appearance the leaves get in mid to late summer due to the combo of heat/dryness/mildew. Most of the LP's around here have already mostly defoliated, while the American Sycamores are nice and healthy NOW, but due to springtime anthracnose, didn't look fully leafed out until almost July. If this cultivar holds up at least reasonably well on both ends, I might consider it. FWIW almost ALL London Planes around here I believe are 'Bloodgood'. Now I can't speak to the differences between MD and WI as far as leaf issues overall, but if your tree looks generally better than the Bloodgood LP would, then I'd probably give it a try....See MoreNative Trees vs. Non-Native Trees
Comments (75)Greenthumbz, those are gorgeous pics! I've heard that there are a couple of trees that are not native to North America but are used by significant numbers of native insects. 1) Malus/Crabapples - native, hybrid, or exotic, Douglas Tallamy's book stated that the leaf chemistry is so similar that North american insects will use all species. This certainly bears true in my experience. I've got lots of crabs, a few specimens and a crazy wild thicket full of them in back,and they are bird magnets, not just for the fruits in the fall but for the nectar and insects in spring and summer. 2) Picea abies/Norway spruce - don't have any personal experience, but was told this by an ornithology student at Cornell who was doing a study on the subject...See Morenorway maple
Comments (18)I am well aware of the process for introducing biological controls. Thank you for the information. Like i said in the avobe post, i had no information on any other hosts. Neither did i suggst that they were biocontrol insects or that they in any way controled this pest. All i saw was a apparently specific insect when you expressed doubt that any existed. I guess i was mistaken on Periphyllus lyropictus - i couldnt find a host list of possible other hosts for it- without that list i guess i shouldnt have jumped to conclusions. thanks for correcting me. There seems to be little specific information available online for Nepticula sericopeza besides that its a seed and petiole mining insect that infests norway- that all is from one sorce - i cant check others. I guess i should have said that all up front... actually looking back i shouldt have mentione it at all because of the scarcity of info wich makes it impossible to draw conclusions. I just wanted to beleive it. But thats the benefet of backtought...See MoreHelp!!! 2018 David Austin Catalog Supplemental List
Comments (9)I think if you look through the website at the varieties that are not Highly Recommended (no star), those are the supplemental varieties. Mary Magdalene has been on the supplemental list for years with good cause, as they readily point out it has poor disease resistance. I've kept it because the blooms are among my very favorites and I was willing to spray, but I'm reconsidering that lately. But gosh is she gorgeous, so maybe she's a good choice for a drier climate than mine? John Clare is another, arguably one of DA's most prolific bloomers. Sorry no pics, seem I never photograph John because he's a bit on the plain side. Great for a constant splash of bright color. Completely defoliates here without spray but keeps on blooming. Crocus Rose seems to be on the hit list. I finally eliminated mine last year. It felt wrong to let go of such an incredibly hardy rose but even with spray it suffered from BS. Perhaps a good rose for a cold dry place. Here it is looking fine in June, but once the temps rise the leaves go black for the rest of the summer. Funny they tended not to drop, but hung onto the plant and looked ugly. Sophy's Rose, I don't understand the problem; my version of BS doesn't seem to trouble it much, so maybe it suffers from other maladies. DA states its disease resistance as only "Good" (which means poor, and "Average" means terrible, don't even thing about "Poor"). Personally I wonder if it's not a popular color for English roses. They try to promote it as a red, but it's more of a magenta and fades considerably. To each his own, it's a stellar bloomer and heathy enough here. Tidy growth habit, doesn't get too large. I can't find any pics of Ambridge. I cherished Ambridge for the fragrance and the delicate blooms. Mine was own root, suffered badly every winter and didn't rebound. I eventually gave it up after a summer where it didn't reach a foot high. Might do better grafted. Seem to recall BS was a problem....See Morefour (9B near 9A)
