Hippeastrum crosses

Posted by Sue_ z6 TN (My Page) on

My first cross has borne seeds! I'm writing for two reasons:

1. Does anybody have advice about starting these seeds? I've heard about the 'floating' method, and I've had some floating for almost a week now without any change...

2. I thought I'd see if anybody wants some seeds of either of my crosses. I'm open to trades of any kind really, but go ahead and check out my page/exchange list. You can also check prussell's page. She's a friend of mine, so I'm open to trades for whatever crazy stuff she's wanting now. I can then trade them to her in exchange for her buying me a beer.

I have a whole mess of seeds which are a cross between Charisma (far left in pic below) and Lemon-Lime (far right). Charisma is the mother (the cross didn't work out well the other way, mainly because the scape with the fruit fell over, and consequently aborted. In other words, it might have worked if I had staked the scape. Word to the wise.).

The pic of charisma is actually the plant in question, in my house. It doesn't really come through in the pic, but the picotee has a fantastic silky sheen. I recommend picking up this hybrid, if you should see it around. In the background, right behind the "ris" in the word "charisma," you can see one of the two fruits (the smaller) on the _first_ scape of that same plant.

This smaller fruit is a cross between Charisma and Double Record, Charisma again being the mother. I could find stamens on the Double, but no style. This fruit just split today, and there's no way to know if they'll be fertile, but go ahead and let me know if you want some of these too.

Charisma is a 'midi,' lemon-lime is identified variously as 'midi' or 'gracilis.' So those two are both on the smaller side. They each bear 4-6 blooms per scape. The double was larger, but not huge, and I think 4 per scape.

I'm going to make sure that the seeds are fertile before finalizing any trades. So let me know if you want some seeds, or if you have advice about getting them going.

This will be cross-posted in the bulbs forum.

RE: Hippeastrum crosses

I've read that planting them right away assures best germination and from my limited experience it seems to hold true. I planted them right away over the years and get almost 100% germination. It's almost kind of crazy. Last spring I had hundreds and fortunately found a woman that could use them for an experiment. I found a packet of seeds I saved from the year before (and misplaced, oops) and sowed them too, but only one out of ~60 seeds germinated.

Hi Sue,

I found that planting them immediately worked well too. So far the only cross I tried- actually a selfing- is with the "xHippestrelia" hybrid, supposedly a cross between Hippeastrum and Sprekelia.

It was so easily self fertile that I'm assuming it's tetraploid, and probably not an intergeneric hybrid at all since there are many different flower shapes in Hippeastrum itself. I'm kind of expecting all the seedlings to look like the parent.

My seedlings are about 1 yr. old now, unfortunately I didn't keep any extra seeds, but sent them out to others. I hope they all got some growing, I'd like to see if there's any segregation in petal shapes at all!

'Breeding Ornamental Plants' by Timber Press is a wonderful book that has an entire chapter about nothing but Hippeastrum hybridizing!

Hippeastrum and Sprekelia have been crossed several times, usually in warm climates -- California, India, Texas. The first hybrid amaryllis (=hippeastrum) was supposed to have had a Sprekelia as the pollen parent. A similar modern cross looks strikingly like Amaryllis x Johnsoni, so maybe Mr. Johnson was right after all.

RE: Hippeastrum crosses

Thank you for those links Karl; Mine looks like the xHippeastralia 'Mystique' in the second site. I always thought it would be spelled xHippestrelia logically, maybe it was first published or registered as "-stralia".

No bloom on my seedlings yet, they were banished to the greehouse due to lack of room and aren't very large right now. Still growing though. In any case I'm glad to see that the cross is accepted and may actually be what I have.

I mean had. The mother plant froze out in January but I still have the several seedlings.
