Where can I purchase disease resistant Horizontal Juniper?

I have found out that not all Horizontal Junipers are resistant to cedar-apple-rust. Only the following are safe: Admirablillis, Adpress, Argenteus, Depressa, Douglasii, Eximius, Filicinus, Glomerata, Lividus, Petrae, Plumosa. I can't find any locally nor on-line. Any suggestions?

Indeed obscure types. I only recognize two of them, maybe. Would love to research this more. Could you divulge the source of your information? Cedar apple rust is common where alternate hosts occur here. I've never seen CAR on any Juniperus horizontalis cultivar. on the other hand, I learn ten new things, every day.

This is the site where I found the info. I'm not sure how to put it on here as a link. http://ohioline.osu.edu/hyg-fact/3000/3055.html

Another you can add to your list of resistant - Pancake™ (not the cultivar name).

Although compared to the specimens I've seen, the pic is deceiving. This Juniper is as flat as it can possibly be, and too small for the regular landscape.

Some more resistant junipers: http://64.233.169.104/search?q=cache:03bTmynYKboJ:www.oznet.ksu.edu/library/plant2/c711.pdf+%22cedar+apple+rust%22%2B%22juniperus+horizontalis%27&hl=en&ct=clnk&cd=19&gl=us
Scroll down to page 8, and page 9 for J. horizontalis.

There are so many cultivars out there, that no one could test them all. Really, all you can say with certainty is not that "these are the only ones resistant", rather, "these are the only ones tested to be resistant". And it is still my personal opinion that you will never have a problem with cedar apple rust on J. horizontalis, unless the juniper is doing poorly to begin with (right plant, wrong place). All information says Juniperus virginiana is by far the prefered species for the disease.

Where are you located, sarahn? J. horizontalis cultivars, including those with cedar-rust resistance, usually are susceptible to juniper-twig-blight diseases which cause branch die-back. For best long-term performance, you might want to consider various low-growing, spreading cultivars of J. chinensis, J. communis, J. sabina, and J. squamata with resistance both to cedar-rust and juniper-twig-blight diseases . A number of these are available at retail nurseries here in the Chicago area. Check out this link from The Morton Arboretum's website (http://www.mortonarb.org/main.taf?p=3,2,8,9,2) about some of the low-growing junipers suitable for the Chicago region--all of these can be found at various nurseries and garden centers around here. (Although some J. horizontalis cultivars might exhibit minimal symptoms of the various cedar-rust diseases, those symptoms can be enough to provide serious infection to the alternate hosts of these cedar-rust diseases--rust-susceptible apple, crabapple, and hawthorn species and cultivars.)

Thanks dwk001. I had given up on on this thread and was going with info I had found at the following site.http://ohioline.osu.edu/hyg-fact/3000/3055.html. I am trying to be a good neighbor and not add anything that would effect the apple trees next door. I'm going to look into this.
