Dischidia ovata seeds

Dischidia ovata seeds!  Though I have been interested, I have never figured out how to hand pollinate Dischidias.  Their floral structure is not obvious, I have never bothered to stick one under a dissecting 'scope, and have yet to find any useful information.  But as you can see, some kindly bug must have finally taken pity.  I was gifted a wee pod about an inch and  a half long and very narrow.  It recently ripened and released the prizes.

Dischidias are a close relative of the Hoya genus, which places them in the milkweed family.  You might have suspected this by the appearance of the seed pod.  If you've ever grown either genus, you'll also have noted that any cut or damaged plant parts exude a white, sticky sap, also reminiscent of milkweed.

I have a few Dischidia species and I find them all to be easy to grow and flower.  Dischidia ovata, though, is by far the easiest.  With almost no encouragement it will creep, crawl, twine and climb all over the place.  It also seems to bloom for much of the year when kept indoors.  I have never found this sort of success with Hoyas.  Actually, sadly, I have yet to have a long term relationship with any Hoya.

Want some cuttings?  Drop me a line via the shop.  I'll probably root some to sell, but they're easy enough to get going, so if you're interested, no sense in waiting on my account.

I have sown my Dischidia seeds in a plastic bag of damp sphagnum.  They germinated within a couple days.

The method is also effective with Anthurium seeds.  Oh by the way - you can expect Anthurium scandens seedlings to become available soon too...

In Bloom: Summer Miniature

Dyakia hendersoniana, formerly known as Ascocentrum hendersonianum, is a very adorable miniature species.  These bloom on an inflorescence up to 6 inches high covered with wee, purple-pink flowers with a white lip in late Spring or early Summer. They can be grown along side Phalaenopsis, pretty much the same conditions but with maybe a little bit more light.  I am keeping mine in slightly stronger light than the phals right now, but they spend the Winter in a slighty shadier spot.  Great plant for those of you looking to branch out, and great plant for the miniature collectors out there too!  Now available in the shop!  :)

In Bloom: Isn't she lovely?

Cattleya aclandiae

I'm quite happy with this.  No, it could have a flatter lip, and my camera could have been less recalcitrant about the color of the lip.  It is actually a very nice deep red-purple in real life, but that shade is just not in my camera's repertoire.  Overall, the color is very dark and rich, which is the form I like most in this species.  As a bonus, it is wildly fragrant from morning through early afternoon, with a fragrance resembling a very nice rose, but a good deal more potent.  

I had a few aclandiae, and after being told they like it dry and hot, I proceeded to mount most of the plants I had.  They did well during the summer, but of course, during the winter I sometimes ignore stuff, and several croaked.  Turns out, if you're lazy with the watering in winter, they're a lot happier in a pot...(see photographic evidence above!)

I do very much like these dwarf Brazilian bifoliate cattleyas, and I'm pleased as punch that I've finally bloomed one of these seedlings.  So much so, that I trolled around here singing "Isn't she lovely!  Isn't she wonderful?"  blah blah blah.  Several comments were made in regards to my probable over-consumption of caffeine.  This of course prompted me to sing louder and put more effort into singing off-key.  This was rewarded with the 'stink eye'.  Now I'm extra pleased with myself.

In Bloom: Albizia julibrissin

All over Maryland Albizia julibrissin trees have been in bloom for the past few weeks. These are also known as Mimosa or Silk Trees, though the former more properly belongs to a related genus to which the diminutive Mimosa pudica (sensitive plant) belongs. I've you've seen those, you'll recognize the family resemblance.  The plant in the photo is a volunteer, which admittedly came up a little close to the house, but they don't get that big and I like them so it stays.   I have carefully protected this thing from 'helping hands', sloppy lawnmowing, and grazing horses since it was a wee, weedy sprout.  Finally it has bloomed.  I am quite pleased with its depth of color.

This species is found in much of the Eastern and Southern ranges of the US, but it is not native.  It is actually introduced and naturalized, and also considered a weedy, invasive pest in certain areas, notably Florida and Tennessee, according to the USDA PLANTS Profile.  Such is often the lot of plants in the pea family.

Yes, this is actually in the pea family.  Family resemblance is more obvious in the structure of the foliage and the bean-like seed pods, less so the flowers due to lack of petals.  Interestingly, however, if you look closely at that flower you'll notice that each of those pink filaments is tipped with yellow.  Those are stamens.

I understand the species is highly susceptible to Fusarium wilt, and so can be short lived in the Northeast as a result.  My mother used to tell me there were many of these trees 30-40 years ago in the DC area with fantastic color.  Then they almost all died out, tragically leaving only the ones with pale color.  Well, fortunately, they're weedy, and so are making an excellent comeback.  They sure seem to be all over the place now.

In Bloom: Moth Diner

Following much personal change and a good deal of procrastination and total distraction with mad knitting, I've decided its time to start posting to the Plant Geek Chronicles again (and, uh, paying more attention to the plants...yep, had some survival of the fittest experimentation).

I'm starting easy, by showing you some goodies in bloom. First, we've got a lovely variegated Neofinetia falcata, tagged as 'Higashidemiyako'.



I'm very pleased with it. It might not be an extremely rare form, but I still think its awesome. Neofinetia falcata is a Japanese species, and all the most interesting plants are still Japanese in origin or recent ancestry. These plants are also easier to grow. I've had trouble with the ones that have been bred in the US for several generations. Likely those are all horribly inbred. But so far I have four that I believe to be of Japanese origin, and not only are they of more interesting varieties, they're so adaptable and easy to grow!

They're also sweetly fragrant, somewhat reminiscent of honeysuckle. As the flower form includes a long spur and the plant displays increased fragrance at dusk and dark, I suspct the plant is probably moth pollinated in its natural habitat. I don't know this for sure, if you have any data on this please chime in.

The other goodie I have to share is a Brassavola acaulis, which I am sure is moth pollinated.



This plant is also cool, and surprisingly sturdy. The 'leaves' are long, pendant...well...green sticks in appearance. Almost based on the appearance and the placement in genus Brassavola you'd assume *Super High Light!* But nay. On the advice of the ever knowledgeable Al, I've kept it with the large mounted phalaenopsis plants, so low-medium light (by orchid standards, mind you ::shakes finger::), and decent watering. Though, to be fair, through the winter I tend to not water enough. The phals were a little crabby about that but they're still alive. Some sources suggest 3-4 hrs light for this species, but mine lives in an East window just fine. It is possible it will adapt to either situation. In any case, it bloomed.

Here again, like most moth pollinated species, it isn't very impressive in the day. As soon as it gets dark, though, you can smell it from across the room. It has a vaguely citrus-y rose-y scent. Very pleasant.

An introduction to Orchids as Houseplants

Frequently I hear ‘orchids are just too sensitive’ or ‘I could never…’, but honestly orchids are not always as difficult as people think. With the number of orchid species estimated at as much as 30,000 species (not a typo, see also Kew: Science and Horticulture: Orchidaceae) and native species found on every continent and climate except Antarctica, plus countless man-made hybrids, finding something right for your house is just about knowing what to look for in an orchid plant. Keeping it alive is just about being well informed (and occasional watering).

How is an orchid different? While there are many answers to this question, what really matters to the home grower is that many orchids, and certainly most of the common types grown as houseplants, are epiphytes. This is a situation where the plants use a tree branch (or occasionally rock crevice) as a condominium. They are not parasitic, just opportunistic. What this means to you as the home grower is that orchid roots are accustomed to an environment where while there might be frequent rain, there is also strong air movement. Many types can even be grown on a wood plaque with no media around the roots (see article here). Similarly, if your nicely potted plant has a root sticking out of the pot somewhere you shouldn’t be alarmed – in orchids this is not necessarily cause to repot. Some orchids just don’t really understand the concept of a pot and so throw their roots in every direction.

Good watering methods are key to root health. Watering of some houseplants is accomplished by leaving them to sit in water for hours at a time. This is not recommended with orchids (with a couple exceptions of some Phragmipedium species that live on river side rocks) as it may lead to root rot. The easiest thing to do is water the orchid by running plenty of water through the pot from the top. Once the media is well wetted, let it drain, then return it to the window.

For best results, orchids are potted in a fluffy or chunky mix that gives a nice balance of holding moisture but allowing air circulation. To maintain root health, repotting your orchids into fresh potting media every one to three years is recommended. Here is a repotting article.

Ok, so all that is great, but how to pick an orchid??

The most important piece of advice is to purchase a plant that is well established. You certainly can have success also with that $5 seedling in a two inch pot, but you will likely find it easier with more immediate gratification to buy a plant that is at least within 1-2 years of blooming for the first time. When buying a plant in person, especially at a place like the grocery store, challenge the plant by gently grabbing the leaves and lifting or moving the plant back and forth to see how well it is rooted into that pot. Good roots mean a healthy plant and more likely success.

Second is to look for a plant that matches your light conditions. For up to a few weeks at a time during blooming you can stick an orchid where it won’t get much light (say, the kitchen table) to enjoy it, but the rest of the year you will want to find a window for it to live in. Here’s a handy guide for commonly available orchid types, based on an unobstructed window, plant sitting right on the windowsill:

North facing window: Rather weak light. You might be able to grow a Paphiopedilum (Paph) there, or some Phalaenopsis (Phal). If it doesn’t bloom for you, supplement with fluorescent light.

East facing window: Great spot for Paphiopedilums and Phalaenopsis.

West facing window: Also great spot for Paphiopedilums and Phalaenopsis. Frequently this is also enough light for some Dendrobium (Den or Dend) plants or certain miniature Cattleya (Slc. or Pot.) hybrids, as well as several Oncidium types.

South facing window: This is your brightest light, excellent for Cattleya hybrids (Slc., Lc., C., Blc., Pot., Sl., Lc….), many Dendrobiums, and Oncidium intergeneric hybrids.

If you aren’t sure what category your plant-of-interest falls into, ask the grower for more details. They want you to succeed too!

I always recommend if you aren’t sure, go with a Phalaenopsis (Phal.) or Paphiopedilum (Paph.). These types are easy to grow, adaptable, and you can always make a very bright window less so by setting the plant back from the glass a little or using a sheer curtain to filter the light. Other culture details are fairly similar for the two types. You can find an article on growing phals here.

UPDATE: IOSPE and Dockrillia bowmanii

Hey folks, just a quick note to tell you I'm still alive and let you know there's a new photo of Dockrillia bowmanii on the Internet Orchid Species Photo Encyclopedia! Check it out here. You may remember this photo - it is one of mine. You can see more photos of the species on this older post.

I did at that time of that post introduce bowmanii and rigidum to each other, but they didn't really get along. There are no awesome seedlings to report. Not surprising. They're pretty different in terms of growth habit, and those weird Dendrobium alliance things can be picky about their dates. Pity.

Remember, if you have orchid culture questions, please feel free to ask. I enjoy chatting about plants, but also questions are usually the inspiration for some of my best articles, and I could really use a jump start! My blogging battery seems a bit dead here. Sorry about that, working on it...
