It is a beautiful deciduous tree which flowers in March/April.
Botanical name: Paulownia tomentosa
Common names: Empress tree, Princess tree, Foxglove tree
Indeed a beauty… thanks … for sharing…
nice to see so much pink. soothing. where is this tree? how tall? what does the trunk look like? and if its near where you are hopefully you’ll shaow us the leaves and the full canopy of the tree. lovely tree when full and the fruits are good too.
wow … is this one of your talks?
and thanks for showing us the three seasons in this ppt
Yes, Di. The last slide is from my State level “International Day for Biological Diversity” Talk organized by Government of Himachal Pradesh at The Gaity, The Mall, Shimla in May, 2013.
can on e-publish such talks
what a magnificent growth. judging from the symmetrical (almost) ovoid shape it seems even though its is a tight urabn environment, it may yet become a specimen tree. unless something seem to have prompted some limb cutting, hope they stop at that. (left side in 2nd pic. )
is this in Simla too?
now wait for a shower of seeds. fun to photograph them and try and grow them. can you save some for me if its in your neighborhood?
And thank you for giving me a treat today. love it
Thank you, … It is growing in Shimla itself. It is fast growing tree. You have also seen the photographs clicked 4-5 years ago. I clicked these photos today as required by Dr. S.L. Kochhar Sir for his forthcoming book. He is also a renowned botanist known for his Economic Botany book.
I’ll collect seeds in March/April when they are ripe.
great. yes i saw that, its right here up in the thread. so can you tell me when his book comes out. economic botany was not an organized science, when during morning walks my dad would tell us about the uses and economic importance of all things green that we encountered.
Back to this Pawlownia: i saw some writings about how fast growing a tree this is and there are plantations in the west that grow them on acres and acres. do we have something similar in india ?
It has started plantation in Nepal also and said to high revenue yielding but side by side the but considered not good environmentally.
why did they say? does it take over forests? displacing native timber?
Some horticulture friends told me few years back about the bad effects of this plant.
Thank you, … i will read it, will be a while the first one is her A. Christina W. Longbrake ‘s phd thesis, and i have found a couple of her other position papers such as this one
There are many links in google …
i know, it has been one of my favorite trees from the times past. what i wanted was news like articles in nepal that may have started. talking of positive and negative aspects of such plantations
I shall check and let you know
On thoroughly checking on net and all our posts, I think Paulownia tomentosa and Paulownia fortunei quite confusing. I could not find the difference between the two on net anywhere except in Flora of China.
Keys in Flora of China are as below:
Pl see the illustration of both as below:
From flowers it is very difficult to arriva eat the species. Also aspect of calyx is also confusing. I think most important character to separate the two is the fruit.
From fruit shape, I think it should be Paulownia fortunei as in
Fruit shape of Paulownia tomentosa is different as per
Missouri Bot. Garden
…, fruit size is also important. In this case, fruits are only 3-4 cm long (not more than 6cm as in case of O. fortunii). I have seen other plants as well but not the fruits in that case.
Actually, both species were introduced in India by the Forest Research Institute Dehradun. I may be having flowering twigs of other species as well and will report back to you.
Pl. check if the pericarp was woody.
But proportional shape is clearly of Paulownia fortunei
Dimensions given are from Flora of China. So in alien environment size, fruit size can vary a bit. But shape is more important.
Thank you for this key, …
Many clues to the species identification are there in this key. I am going out to do some more research
Also send original image of fruit.
Were the flowering images from the same tree ?
… all of my photographs at efloraofindia are from the same
Flora of China says Mountain slopes, forests, mountain valleys, wastelands, below 2000 m for Paulownia fortunei (Seemann) Hemsley in F. B. Forbes & Hemsley and Usually cultivated, below 1800 m for Paulownia tomentosa
…, this plant has been introduced in H.P. by the forest
Thanks, …, There has always been misidentifications and confusions when it comes to introduced species.
Images of buds and flowers above does not prove anything.
I think best to go with the following, where fruit is also depicted:
Than there are cultivars as in https://paulowniatrees.eu/learn-more/paulownia-species/
I have tried to compared my plant with the description given in the Flora of China. Kindly find attached a copy of comparision for further reference. Based on these evidences, it appears that my plant is Paulownia tomentosa only. I had clicked some plants in the campus of Dr. Y.S. Parmar University of Horticulture and Forestry at Solan a few years back, which I was presuming as P. fortunei. I’ll see them again in new lighjt. Some more photographs are attached. The number of flowers per cymes are clearly visible in one of the photographs.
Measurements of leaves and old fruits (they remain on plants for longer periods) are taken today only. Leaf size can still increase as they start appearing only in the month of April.
Comparison of Paulownia spp. Based on Flora of China
Thanks, …, for the superb images as well as all the hard work.
We are all doing this research work day in and day out (and publishing on our site), except for publication in research magazines.
It is your hard work, … You are curating each and every species and devoting lots of time researching all these.
Thanks, … Problem is all the research is not reaching to the laymen as well as the botanists, which we are trying to do.
Canopy architecture is an important character if the plants are growing undisturbed.
Tree for Id from Karnal-Haryana: This tree is flowering theses days at a few places in our area. This is quite uncommon here, the picture taken is from Karnal City (not much clear because of being distant as this was growing in a private property). Looks to be a member of Bignoniaceae. Please help me identify this beautiful tree.
I thought this to be Paulownia from family Paulowniaceae. Earlier it was placed in Scrophulariaceae
Yes Paulownia fortunei… I think
Fruit image may finally help in confirmation of species as per discussions at Paulownia tomentosa
In view, we may take it as Paulownia tomentosa for the time being, being in the plains and close to Delhi.

This images of this large tree were recorded from a private property in Panipat..
also earlier from Karnal.. please validate if this can be Paulownia fortunei (Seem.) Hemsl.
An introduced tree from Paulowniaceae, earlier Scrophulariaceae..

Attaching two images of a small tree whose flowers and leaves look like an Ipomoea Sp. Can some one identify the species for me?
To me it is Ipomoea crassicaulis
It cannot be a species of Ipomoea. It is a bignoniaceae member. Looks like Catalpa species. C. bignonioides (?)
This is same as FOI, description can be found in http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=200020797 and I have already sent a mail to … and he thinks the suggested ID is possible.
for a few years i was mistaking catalpas with Paulownias
one useful quick study is here by Herb Amyx at
simple English distinctions…
it also goes to show that not only flowers but the leaves must also be photographed with care.
… is right. At the outset, both species look similar. I too had the same problem. Thanks for forwarding the relevant link for distinguishing them.
Thank you … Both the genera are unknown to me. This is the first time I hear/read of Catalpa and yesterday it was Paulownia. When I saw these photographs my first reaction was ‘something like Asystasia‘, so I searched for Acanthacaeae tree…..
But the difference given in the link … pasted needs to be modified as per FoC (or other eflora) –
Based one the above links this should not be Catalpa for its calyx feature.
Thanks for your communication. I learnt a lot from these links. The purpose is to get the correct ID.
NOT any Convolvulaceae. I agree with …
I still think it is Paulownia, but not sure of the species, though still think frotunei, can be confirmed only by fruit, following links may help –
I tend to agree with … It seems to be Paulowania
To me also, it appears to be Paulownia fortunei
It must be Paulownia only. No doubt. Thanks for updating me.
Fruit image may finally help in confirmation of species as per discussions at Paulownia tomentosa or otherwise.
Taken at delhi (near my residence) on 26.3.08
Would appreciate id help
Some Paulownia species?
This appears to be a Paulownia species, though most species I’m familiar with are more often shades of violet/lilac, rather than yellow. Hopefully someone else can provide more information.
Interesting ..Never seen in my area. Pune.
Looks like Paulownia. But not confirmed. Can … send the photos of foliage.
Attaching the picture of foliage.This is all i am having for the moment (the foliage is high up but I can try for a better shot).
Looking at Pradeep Krishen’s book, I think it could be Paulownia tomentosa. The book mentions only one place in Delhi having the tree. If so this is the second place (yamuna sports complex).
But the flowers have different colours (pale purple or tinged with voilet as per Trees of Delhi) for Paulownia tomentosa. See the link
I guess Paulownia tomentosa !
Location: Kathmandu, Nepal
Date: 24 March 2015
Altitude: 4400 ft.
Superb image set.

Tree for ID : Atlanta, Georgia : 09NOV18 : AK-5 : 4 posts by 3 authors. Attachments (4)
A small tree growing wild by the roadside. Seen last month during my visit to Atlanta.
Leaves were bigger in size and heart shaped.
Absolutely brilliant! Yes it does match with your suggested id.
deciduous tree-grows upto 50 feet.
Native to China, Laos, viatnam.
Named after Queen Anna Pavlovna of Netherlands.
Was not aware of any tree from Family Scrophulariaceae.
Huge1 We have seen all tiny miny plants of Scroph
True. This also comes under Paulowniaceae family.
a few trees of Paulownia are in Delhi also…. the tree was imported (from Australia probably) a few years back by forest department for use as a timber tree but the tree just took the conditions to be very favourable and grew very fast and thus depriving the wood of its strength…. hence a useless tree…
Paulownias are seen in plenty in U.S A also.
The pendulum has since swung back and now Paulownia is considered a good candidate for biomass production. Here is a link to an article which appeared in the Hindu. The Hindu Business line
please identify these photos which from Nagaland’ : 5 posts by 3 authors. Attachments (5)
This plant was posted at FB Group Plant Wealth of India for Identification by …, clicked in Nagaland.
I think, this is Paulownia fortunei (Dragon tree). However, close observations are required for confirmation. I can ask him to send these photographs to efloraofindia.
I guess … is correct!
Identification required for this sp.: 1 high res. image.
Found in upper hills of Ganderbal district. Kashmir
Seems to be Paulownia sp.
You need to post the habit, foliage and other photographs for proper ID. I think you are well aware as you are a professional taxonomist.
Sure sir…. I will post all photographs
Maybe Paulownia tomentosa, as per images and details herein.
Would it be possible for you to share images for the following species for the purpose of my
using them in a book I am coming up with?
