sounds like a hard frost.. or freeze ....if you lived in z5 .... affects one plant.. and misses something right next to it.. go figure ... any recollection of such in the last 2 weeks??? ken

I have a sugar maple growing in our backyard that I planted as a seed (collected in Barrie, Ont.) around 1992. It got about 10 or more feet tall, then we had a severe winter around 10 years ago and it was killed down to about 1-1.5 feet above the ground. But I left it alone, and it is now probably 15 feet high, with a multi-stemmed trunk, more like an upward spreading bush. I know of some better specimens in Edmonton about 30 feet tall. I have a butternut that is about 15 ft. tall by 15 ft. spread, planted as a seed in the early 1990s. It seems healthy and has produced nuts for the past 5 years or so, but I know it isn't fully hardy because it gets a big vertical split in the trunk each winter. I tried a Star Magnolia but never got it to bloom. It came back each spring for about 3 years, but a little smaller each year due to winter dieback, and I eventually took it out. I've tried black locust (Ontario seed) but it winterkilled each year above snow-line so I removed it. I tried dwarf Catalpa (seed from Gardens North) said to be hardy to zone 4, but it also winterkilled above snow-lines so was removed after several years. My six hybrid tea roses have been much more successful, winterkilling to the ground each year but re-growing quickly so they reach 3 feet or so in summer, with loads of blooms. Those have been in almost 10 years. Then there's Edmonton's famous horse chestnut growing downtown, now something like 75 years old. There was a program a few years ago to distribute seedlings from this tree and get them planted around the city, but I don't know how successful that was. George Pegg Botanic Gardens northwest of Edmonton has a nice black walnut tree that produces nuts. And you may have come across the posts from that guy in zone 4 in Colorado(?) who grows palm trees outside, though he does use an elaborate heated-box system to protect them during winter.

The only tree I have known as "lime tree" has been Tilia cordata. The fresh, sweet, lingering aroma of this tree is certainly one of my favorite summer fragrances. I look forward to it every year.

Eucalyptus trees were planted in parts of Israel that were swamps to drain them. They have done the job. They also grow fast when given much water. Be careful with what plants are poisonous to horses. Oleander is one that is poisonous. I had a cow that died from eating Oleander. Do a google search as I have done. Felix
