I have around 50 Eucalyptus dalrympleana seeds that I had in the fridge cold stratifying for at least eight weeks now (maybe longer, I forgot exactly) in a damp paper towel. The seeds are super tiny. I was going to germinate these in a little closed container just on top of some moist soil. I heard they can germinate fine at tempatures around 65°F. Does anyone have any advice about germating these? I never germinated Eucalyptus seeds before.
Does anyone know if this is a Eucalyptus neglecta? I bought it as Eucalyptus neglecta 'Big O' from a place called Soutgern Eucs, but am not sure if that is what it is, since I looked it up online and in the pictures I found they seem to be a bit different. Could it be a different species?
I bought this Eucalyptus in 2012 and planted it right away. It was labelled Eucalyptus dalrympleana but I have always had some doubts. It is very fast growing, especially considering the climate (short summers, lack of heat) and it has proven to be quite coldhardy. The worst damage so far has been some leaf spottings on older leaves. We regularly see snow and frost down to -10/-12C in winter as well as prolonged freezes (january 2017 was virtually always below freezing).
This tree only receives sun until noon/ early afternoon, so it is a bit leggy. I planted a sister seedling in my aunt's garden in full sun but it grew so fast that she cut it down three years ago. Grown in full sun, it had a much stockier and bushier appearance.
Any ideas? It was suggested to me that it could be E. parvula..
It has flowered various times
Perhaps one of those rare topics not posted here much ( I could be wrong). I thought it might be interesting to share some pictures of flowers from a slightly different perspective.. after the sun sets. In a way, near complete darkness, sans flash, brings out some details the sun might otherwise wash out.. anyway.. enjoy.. and feel free to add your own, if you dare venture out into the garden after the sun has set.
Brunfelsia plicatilis (spelling?) Intoxicating fragrance, esp. on warmer humid summer evenings
Harrissia fragrans..The endangered FL/Caribbean Apple Cactus
.... A couple Plumeria ( #1 Yellow spider #2 Maui Beauty)
Ghostly weeping White hibiscus
Rangoon Creeper- single flowered type
Randia echinocarpa Buttery Cinnamon/Chocolate/Vanilla sent on a stormy Sonoran Desert summers night
Fireworks?.. Fiber optics? ..Aliens??.. or Pseudobombax ellipticum V. Alba
Menodora longiflora, Rare S.Texas /N.E.'rn Mexico native in the Olive family. Tough and very fragrant after the sun sets.
..And of course, Guaiacum coulteri, ..by night.. still stunning, imo.
I've recently become very interested in what Eucalyptus trees can grow well in zone 8 of FL Panhandle. I recently ordered E. viminalis and E. dalrympleana from rarepalmseeds and am very excited to try them.
I've done a lot of research- much of what I found was sheer minimum temp tolerance of various species, but looking into things more, I've found that doesn't necessarily mean it will thrive in S.E. U.S. conditions.
Apparently where they're from in Australia, the temperatures are more constant. They seem to not like roller coaster temps that is so typical of the SE U.S.
Anyone else have much experience growing different species of Eucalyptus in the Southeast U.S.?
The only Eucalyptus trees I've seen growing in my area are Eucalyptus cinerea, or silver dollar tree. Here are a few I've seen.
I'd love to grow some of the more bold and distinct species that would really stand out from the somewhat mundane, scrub vegetation of my area.
Here are some of the articles or sites I've found that give more insight as to how these trees react to SE U.S. conditions.
Introduction of Eucalyptus spp. into the United States with Special Emphasis on the Southern United States
Here's the abstract:
Introduction of Eucalyptus spp. into the United States from Australia on a significant scale resulted from the gold rush into California in 1849. Numerous species were evaluated for fuel, wood products, and amenity purposes. The first recorded entry of eucalyptus into the southern United Stated was in 1878. Subsequent performance of selected species for ornamental purposes caused forest industry to visualize plantations for fiber production. That interest led the Florida Forestry Foundation to initiate species-introduction trials in 1959. The results were sufficiently promising that a contingent of forest products companies formed a cooperative to work with the USDA Forest Service, Lehigh Acres, FL, USA, on genetic improvement of selected species for fiber production. The Florida initiative caused other industrial forestry companies in the upper South to establish plantations regardless of the species or seed source. The result was invariably the same: failure. Bruce Zobel, Professor of Forestry, North Carolina State University, initiated a concerted effort to assess the potential worth of eucalyptus for plantation use. The joint industrial effort evaluated 569 sources representing 103 species over a 14-year period. The three levels of testing, screening, in-depth, and semioperational trials led to identification of some species and sources that offered promise for adaptation, but severe winter temperatures in late 1983 and early 1984 and 1985 terminated the project. Despite the failed attempt valuable silvicultural practices were ascertained that will be beneficial to other researchers and practitioners when attempts are again made to introduce the species complex into the US South.
