The bicolour is combinations of yellow, pink or orange with mauve and the Tricolour is can be the same but with white is that what you meant?

I meant is this plant unique, something entirely new? I have never seen anything like it before, and I've had this particular plant for 7 years, it's always borne orange flowers.

Well tricolour means 3 colours and I have seen quite a few on here in the last few weeks like this one GB. Perhaps someone else can tell you more?

I have tried searching for Buddleia globosa tricolour but all I get is my own question! I am not sure how to search for this particular variety. But if it's not unusual I guess that answers my question, that it's not a new variety! Thanks for answering Drc726 :-)

Its only my thoughts Galaxybabe wait and see if someone who has a similar one answers you. I will try looking for the couple of photos I have seen recently and let you know.
Gladiolus callianthus is a yellow ball and several members have posted photos, but you said 'Gladiolus callianthus Tricolour' and on line it does comes up as a three colour one.

Found some at last - if you go to Karensusan63 she has posted 4-5 photos and 2 look like yours, Lilac and yellow but hers is called Buddleia Weyeriana 'Sungold' Shirleytulip has also posted a Buddleia Weyeriana 'Sungold'. David has posted a Buddleia globosa which is all yellow as has Mikec, Do have a look and lets know what you think?

Galaxybabe, Drc is right in that the inflorescence is more like B. x weyeriana than B. globosa. It may be a bud sport of 'Sungold', especially since the top side of the spike is coming out lilac, while the bottom is still gold. As such, it counts as a new variety, and could be patented and named, though it sounds like it could be a common mutation, as found by Karensusan.

Wow, thank so much! I've been to Karensusan63's page and found her Buddleia Weyeriana 'Sungold', the 2nd photo shows this exact mutation. Now I have to find out how to change the classification on my garden plant (hah!). By the way I was sold this plant as "Buddleia globosa" by a plant centre close to my home. Perhaps I should ask for a refund? (I'm joking, it's given me many years of pleasure, and now it's turned lilac I feel truly blessed!)

Kind regards, Ann aka Galaxybabe

P.S. I am looking forward to spending more time here and browsing the wonderful photos. It's truly astonishing the beauty and the diversity of nature!

Thanks from me to Tugb. Glad you have an answer Ann. Enjoy it.
I have bought plants that turn out to be not what it says on the label or often its a different colour. The growers are not always to blame I have seen customers remove labels to read them and then just throw them down.

Or take them home to show their "signifigant other", or put them in some other pot.... Also, things have come mis-labelled from the growers, and the retailers are legally required to let the mis-label stand!

I wonder why its legally required Tugb?

I suspect that it is a too-broad solution to another problem. Before the laws, "George Smith" could order a lot of 'Margot Koster' roses for his nursery, and then change the labels to read "'Smith's Orange' rose", and enjoy banner sales--at least until his customers realized that it was just a common 'Margot Koster', that they could buy for 1/2 the price on mail order. I think that it has been more than 60 years since that practice was common.

I see now, thanks Tugb

I think I have an explanation for this, which I have also seen this year on B. x weyeriana Golden Glow. It is down to the genetics of Buddleja davidii (B. x weyeriana is an F2 hybrid of B.davidii and B.globosa). White Buddlejas don't lack the genes for anthocyanin (the lilac colour) production rather the pigment synthesis is suppressed by a protein/gene called ALB2 in many cultivars. The yellow colour production in B. x weyeriana is completely separate in every way to the lilac. When the best yellow flowers were selected it was those hybrids with minimal and transitory lilac pigment production that didn't mask the yellow crocetins that were best. What you are seeing is a localised failure of the suppression of the lilac colour. Unless an entire stem undergoes this suppressor protein loss, from which you take cuttings, it will not be likely to be stable or repeated. So it's not a new variety yet.

Just my theory. Hope this helps.

Thanks for that B
