Hi all,

it´s no wonder after i was able to cross D. ascendens ("Bandeira Peak") with D. tomentosa var. tomentosa (´Morro Do Jambeiro, Minas Gerais, Brazil´) some time ago that the reciprocal crossing should work as well. I waited with showing pictures of that crossing until the plants have grown up to majority. So here are the resulting plants of D. tomentosa var. tomentosa x ascendens.

In my eyes the plants look almost identical, the leaf shape, the hainess on the lower side of the leafes, the size of the plants and the hairness of the flower scapes seem to be almost the same. Only the colouration is a little bit different.
I wonder if the flowers will also look identical but it will take some time until the first flowers will open.

Here is the link to the plants i showed last year (D. ascendens x tomentosa var. tomentosa) where you can also see how the parents look like:
D. ascendens x tomentosa var. tomentosa

And here are the pictures of D. tomentosa var. tomentosa x ascendens and for comparison i took also some pictures of D. ascendens x tomentosa var. tomentosa side by side to the new crossing.












on the left is the new crossing






and again alone




Best regards,

Dani

Hi Dani,
a fantastic hybrid!! Are these from seeds from F1 or F2 generation?

best regards and merry x-mas

[Daniel O.]

Many thanks Tobias.
These plants are the F1 generation.

Merry Christmas,

Very gorgeous plant. What are the growing conditions that you give for this hybrid?

[Daniel O.]

Thanks.

It seems to be an easy grower, watering year-round by the tray method (permanetly about 1-2cm), artificial lights, the day temperatures in the moment are about 20-22 degree, at night about 12-15 degree. For sure the night temperatures will go down the next few weeks but last year they have continued growing without any problems. But they also don´t have any problems with high temperatures during summer.
They do not grow in a terrarium, they grow in open trays in my house.

Best regards,

Dani

What a beautiful plant Daniel!

[Fernando Rivadavia]

Thanks and congrats!!! :)

[Daniel O.]

Many thanks.
In a few days the flowers will open so i will be able to take some pictures of them.
The D. ascendens x tomentosa var. tomentosa hybrids are also in flower in the moment so i will be able to compare them.

Best regards,

Dani

Hi all,

a few days ago the first flowers opened and i was very surprised to see 4 open flowers at the same time, it looked really great.
The flowers are nearly 2cm in diameter and are as big as the flowers of the reciprocal crossing, in fact much bigger than the flowers of D. tomentosa var. tomentosa.
In the upper part the flower scapes are hairless.










And here the comparison between this crossing (D. tomentosa var. tomentosa x ascendens) and the reciprocal crossing (D. ascendens x tomentosa var. tomentosa), the flower at the left is the one of the reciprocal crossing, the others are these from above.




yesterday only one flower opened




Interestingly both hybrids do have much longer flower scapes than each species itself has.

Best regards,

Dani

[Miloslav Macháček]

They are really wonderful flowers :-) great shots!

[Fernando Rivadavia]

Very nice, thanks!!!

I often see this hybrid vigor with natural crosses in Brazil, where flower scapes and flower size are larger than in the original parents.

Congrats!
Fernando

[Carlos Rohrbacher]

Oh, nice flowers in very good pictures.
Thanks for sharing, Daniel.

[Daniel O.]

Again many thanks.

@Fernando, the flower scapes of D. tomentosa var. tomentosa x D. tomentosa var. glabrata (and the reciprocal crossing), D. ascendens x schwackei, D. tomentosa var. glabrata x D. graomogolensis and D. schwackei x tomentosa var. tomentosa are also much longer than in the parents.

Best regards,

Dani

[Fernando Rivadavia]

Thanks for the info Dani! I wonder why this hybrid vigor is so pronounced in flower scape length....??

I have not really an idea but it´s strange that all these hybrids do have longer flower scapes.
But perhaps these longer scapes are a method to increase the chance to be pollinated and thereby to be established.

Best regards,

Dani
