Stephen,

the Prunus laurocerasus cultivar I know under the name 'Camelliflora'. We have these cultivar in the nursery I work.

Thanks John and Mark, Staphylea, the Bladder Nut. That's why I somehow knew it

Thanks, Uli - I see now from my notes that I had put a question mark by this one - the plant label was worn out. However, googling this name it seems that Camelliifolia is correct

the rubus is quite interesting!

[Lvandelft]

Living in a very windy area near the coast I don't see any leaves on shrubs and trees here.
Except for Liquidambar, which is the only small tree giving some color in the garden.

seeing stephen's paulownia earlier made me remember a question i have for john weagle----

john, you apparently grew a paulownia tomentosa variety from seed that was donated to the historic garden here in annapolis royal. that has now flowered for the past two years and is a healthy specimen.

however, here is my question/quandary....it looks in all respects like a straight p. tomentosa to me, although it was *apparently* grown out as P. tomentosa 'Coreana' (hybrid name, not ssp. or variety). don't you hate this? glad the rules were changed to disallow this sort of plant naming.

OR

were your seedlings P. tomentosa (of Korea origin)????
everyone around here is confused and I would like to help get the nomenclature sorted out.

Mr. Krüssmann wright in his book about this cultivar: 'Coreana' only a clone from Gardens in Korea. Described by Uyeki in 1925 as P. coreana. Mr. Hu, Shiu-ying classify the species back to P. tomentosa in his work A monograph of the genus Paulownia in Quart. Jour. Taiwan Museum 12, 1-54, 1959.

[Kristl Walek]

thank you, Uli.

the cultivar was described as "leaves tinted yellow, wooly beneath" (which the clone here does not have).

i guessed that this plant was probably grown from seed of Korean origins--which might have made it hardier---but
it seems that even in mild Nova Scotia, this was not enough, as i was told that the tree is decades old (kept getting severly knocked back each winter). only in the past few years (global warming?) has it finally survived to reach blooming size.

i have seen it in the American south where it has become a noxious weed.

back in Ontario, i grew it in the garden as a re-sprouting stool for its tropical foliage.

Indeed.  Paulownia tomentosa 'Coreana' would indicate a selected named clone of tomentosa and not suggest hybridity at all.   P. 'Coreana' would be a different matter but then any interspecific hybrid would have probably been named with an x ______ 'Coreana'.  I will have to dig through my records back to the late 80's I think, it was around the time Heptacodium became popular but had another Genus name which always escapes me.

John, I do not know of any earlier genus name for the monotypic Heptacodium.  I do know that in earlier days, this popular tree was first named Heptacodium jasminoides, then was later renamed H. miconioides.

Aha  - So it was H. jasminoides, NO WONDER.

The previous owner of our property planted a number of Catalpa bignonioides - 3 of which we moved successfully to where it suited us.
This one appears to be the clone with a purple cast to the young foliage and is slowly making a decent sized tree.
cheers

Fine trees, fermi! I have always wanted Catalpa in my garden but the summers here are not warm enough. They grow in gardens in the southermost parts of Norway though.

[Hoy]

Here are some trees I like:

1) Mountain birch. These trees have been destroyed by the larvae of birch moth. That makes them a little trollish!

2) and 3) A tree planted in the yard is called a "tuntre" in Norwegian (litterally "yard-tree"). What's the English term for that? Here from the tiny island of Stråholmen, Southern Norway.

[Maggi Young]

Trond, given the capacity of many UK citizens to plant totally unsuitable forest trees in their gardens/yards, I suppose the most appropriate English term for such tress would be  nuisance trees, because they are too big, cause damage to nearby drains and houses etc!
