Hana's cacti

[Hanazono]

This morning was cold. Even in the greenhous, it was 4 'C.

I found flowering buds of Myrtillocactus geometrizance on the North face.
The cactus is in my backyard. The Norce face is warmer in here.

I have not seen these flowers yet. I hope I could see soon.

If you can see small flower buds now, then you will sure get some flowers next Summer.
Each rib will have at least one or two flowers.
My F. herrerae started to flower in early April, and still have one flower last week, but because the weather is too cold and not enough sun, it wasn't fully opened.

G'afternoon Bryan,

Thanks for your information.

My F. herrerae started to flower in early April, and still have one flower last week,

I hope I could see some flowers next April.

Two cacti on photos are Astrophytum hybrid which show a special body colour.
The colour is called "Twilight variegatin" which is not a true variegation, comes from hybridization problem.
They normally die during young seedlings but they have been able to survive. I have not seen their flowers yet.

<…> The photo is 3 Ferocactus species set in my backyard.
One is F. chrysacanthus v rubrispinus and other two were propagated from Ferocactus mix seeds. I do not know names of these two.

Why they are looking not very happy? Is F chr.rubr. sunburned? They stay always on the same Place in same position?
Regards, Antti

G'morning Antti,

Why they are looking not very happy? Is F chr.rubr. sunburned? They stay always on the same Place in same position?

The ferocactus chrisacanthus v rubrispinus is left-back, smaller one.
Sunburn is on front one which is unknown name currently.

They all are under trial. I keep cacti in greenhouses and I can not see the true figure of Freocactus. Spines of Ferocactus kept in a greenhouse are thiner. I want to see thick spines of Ferocactus similar to habitat cacti.

3 Ferocactus are out-door.
They are on same place but chrisacanthus is for 4 years others are just for 1 year.
Since this is the trial, I just look at spines only.
Temperature in summer in here reaches 45 'C and it is very dry which is similar environment to habitat, I think.
Ferocactus will be sunburn easily in summer.

Today is 1st of July which is similar climate to 1st of January in Northern Hemisphrer, mid of winter. July is the coldest month in here.
All cacti stop to grow and wait the coming spring.

That’s interesting. Does anybody knows why they tend to die as seedlings? I don’t know if there anything like lethal genes in plants but in dogs the blue merle dogs shouldn’t be mated to other blue merles as it can result in serious health problems. https://www.dogingtonpost.com/double-me ... eventable/

G'morning Mrs. Green,

I think cacti also similar to the dog which you referred.
Seedlings are pale/yellow and very short life.

It may not enough sample numbers but the followings are my experience:
1. asterias, yellow petals and orange throat
2. capricone, yellow petals and orange throat
3. senile, yellow petals and orange throat
4. coaphuilense, yellow petals and orange throat
5. red flowering asterias, red petals
6. myriostigma, yellow petals
7. ornatum, yellow petals
8. caput-medusae, yellow petals and orange throat

Pollination: Mother x Father
2 X 1: No issues
3 x 1: No issues
4 x 1: No issues
2 x 5: No issues
6 x 5: All of seedlings had problem. I could graft 24 seedings but all of the turned to yellow and short life.
7 x 6: No issues
6 x 8: It was hard to make seeds. Just 2 myriostigmas could make small number seeds. The germination was on issue but cacti could not make any flowers.

Good guide for those wanting to have Astrophytum hybrid success.

[MrXeric]

I really enjoy these informative posts, thanks for sharing Frank.

Thank you very much Hanazono. Very interesting!

I fused several species as a trial. I found the method was not so valuable if the growing speeds of two species were so different.
A typical sample is Ariocarpus + Astrophytum.

The photo is Ariocarpus retusus v furfuraceus + Astrophytum hyberid fukuryu banjyaku which is the best result of the traial.

fused how?
Fused roots?

[Hanazono]

G'day nes,

fused how?
Fused roots?

The photo is the fusion process which I did in 2017.
Seedlings of both Astrophytum and Ariocarpus were sliced body side off and tied together by a yarn. (fusion)
Above two was gradted together onto a pereskiopsis. (grafting)
Both process fusion and grafting run at the same time.

They were degrafted later.

That's impressive, must be really tedious.
