what colouer is flower of perovskia species ?

Hi bluestare. Perovskia (Russian Sage) has a lavender-blue colored flower. It does so well here in my zone. Are you thinking about growing it?

bluestare.

Wikipedia tells me the following:
'Russian sage produces spires of small, tubular flowers of blue or lavender colour.'

Perovskia is a genus of flowering plants in Lamiaceae, which have 9 species. 2 species are different colour , yellow and white . I want to know which one of them are?

I'm not familiar with those, I don't think. Hopefully someone else will be along soon with some more information about your question.

Even Google isn't familiar with white or yellow perovskia. They mainly show the typical 3 - 4' tall atriplicifolia and the 2' tall 'Little Spire', both of which are lavender-blue with grayish stems. It is the background plant in this photo:

.....Most [Perovskia] have violet blue-flowers, only two have a different flower colour - P. scabiosifolia has yellow flowers and P. scrophulariifolia f. albiflora has white flowers.
-- RHS Plant Trials and Assessments ---- rhs.org.uk/trials

Of course, there is always the possibility of albino anomalies in most species of anything.

You're more informed than Google!

It actually comes up in google, you just have to look carefully.

Too early for me since yesterday was way too busy!

Still haven't spotted any in yellow.

It took half the day, but I found the answer.
P. scabiosifolia has yellow flowers.
P. scrophulariifolia f. albiflora has white flowers.

Assuming that this link has correct information:

Edit: Sorry, I got here late!

That was the only reference I was able to find, too. Odd, that.

Try keying in 'Uzbekistan' with the botanical plant name and see what else you find.

Welcome bluestare!

There are a few Perovskia listed in our plant database, the ones with photo's seem to be the blue/lavender varieties. Here's a link if you'd like to check them out:

thank you Greene for your answer, but in nine species of Perovski in Wikipedia I couldnot find P. scabiosifolia.

Wikipedia doesn't know everything and neither do I, sorry.
Leftwood, Woofie and I all found the same link.
That's all I know.

These plant names can sure be confusing at times. I was curious so I went to The Catalogue of Life website and typed in Perovskia scabiosifolia and it came back "No records found", so I typed in just the genus Perovskia and these are the only ones that showed up:

Perovskia abrotanoides Kar. Species accepted name
Perovskia atriplicifolia Benth. Species accepted name

At The Plant List website, the following are the only ones listed:

Perovskia abrotanoides Kar. Accepted
Perovskia angustifolia Kudrjasch. Accepted
Perovskia angustifolia Kudr. Unresolved
Perovskia artemisioides Boiss. Accepted
Perovskia atriplicifolia Benth. Accepted
Perovskia botschantzevii Kovalevsk. & Kochk. Accepted
Perovskia kudrjaschevii Gorschk. & Pjataeva Accepted
Perovskia kudrjaschevii Gorschk. & Pjat. Synonym
Perovskia linczevskii Kudrjasch. Accepted
Perovskia pamirica C.Y.Yang & B.Wang Synonym
Perovskia scrophulariifolia Bunge Accepted
Perovskia virgata Kudrjasch. Accepted

And there are only two Perovskia listings on ITIS.

I couldn't get ITIS to respond for some reason but The Catalogue of Life is apparently part of the ITIS site.

Even experts do not always agree. Everything is just one source for your consideration.

I really don't understand wikipedia and why it's the site everyone goes to. I avoid it, and the only time I might visit is to see if there is a reference I missed. The reference section in the Perovskia page is really embarrassing!
---- GRIN has never claimed to be anything more than agriculture related. It not at all comprehensive, and only lists two Perovskia spp.
---- There are only three references, and no where in the references are there more than two (count them two!) Perovskia species listed. (So where did the writer get nine?)
---- Click on any species link (except for P. atriplicifolia) in the article body and they bring you to a a wikipedia "page" for said species that exists in title only.
