I would post to the Cactus and Succulent Forum.

Oops, Cacti and Succulents.

Epiphyllums can "sport" like african violets and hostas do. That seems like the most likely explanation to me.
Or maybe a seed germinated in the pot and since it was a seed it didn't grow true to the parent plant?

Linda, good idea..thanks.

Summer. Maybe you're right. I haven't any ideas why or how it happened.
Where would the seed come from?
Whatever the reason, I like the idea of different flowers in the same plant. lol. Toni

Hi Toni,

from what I can see your first photo appears to show an Epiphyllum oxypetalum in bloom (the leaf and flower combination is unmistakable) now your next photo's are most definitely of a different plant! (probably of Epiphyllum 'Ackermannii' hybrid origin) most likely what has happened is that the original plant you bought was a mixed bag of cuttings so to speak from multiple plants so they may appear to come from the same plant but actually it is multiple plants in the same pot =)

I hope I have been of some help ^^

Another clue that they are different plants: the Epiphyllums have no spines. The red one will have tiny but robust spines in the aeroles.

I didn't know that! is it the same for all species Epiphyllum? so the spines must come from intergeneric crossing? (X Disocactus, X Heliocereus, X Selenicereus, X Aporocactus etc.)

I do love tit bits like that =)

Epiguy, Epiphyllum oxypetalum and its crosses don't seem to have spines, and neither do any of the other species I've seen. Disocactus is another genus.

I don't think many Rhipsalis have spines either, only the one called R. monocantha, which generally has more than one spine ('monocantha' NOT!). The rest have either no spines or they are small hairs.

Toni,

That's like apples and oranges - yes, they're both fruits, but they're not the same.

Thanks...

Whatever happened, new blooms are growing in as Night Blooming Orchid Cactus..White and pink.
Oh well, a fluke?

Jeff, apples and oranges, epis and phyllums.

Is it the apple or orange that took 18-yrs to show itself?

Toni, except for one species that I am aware of, all Epiphyllums have white flowers that open at night. Disocactus have colored, day opening blooms. Both are epiphytes, only one is Epiphyllum.

You will also find that the Epiphyllums will bloom a large flush of flowers, then nothing (maybe one or 2) for about 8 weeks, then another massive output. For me this means the last ones open in Oct. Cool mornings mean the flowers look good until almost noon.

The Disocactus ackermannii seem to bloom once in the spring/early summer, and then only a few until next year.

Howdy. So, which is my plant? lol. Flowers open at night. I once took a late night picture, but pic looked nothing like the actual flower.

I always believed it to be Night Blooming Orchid Cactus.

My Epi blooms throughout summer. Sometimes as early as Feb, but buds/flowers are tiny. As time progresses, buds grow bigger.
BTW, the newest flowers are pink and white, once again. I'd like to see the round, red blooms, but think it was a fluke of nature. :)

Also, yesterday,, while browsing through pics on paper, non-digital, you know, the old-fashioned types? lol
I got the Epi 1994..it first flowered in 1997. So, it bloomed after 3-yrs, not 7. Sorry about that. Toni
