The Lilac Dénouement

Lilacs can be slow to bring into bloom. Most of these were either from small, bare-root plants, or from tiny starts that probably originated from tissue culture or cuttings. These have been in the ground here at least 4 or 5 years. Earlier, I gave them a boost of fish emulsion, hoping that it would stimulate growth for next year. The older lilacs have bloomed for a few years, but this is the first time for several. Our intent, was a blooming hedge for some privacy. They are not yet to that stage.

Nice purple. Fragrant.

Nice white. We cheated - it was purchased last year at the Lilac gardens, and was already in bloom at the time.

I've been carefully pruning this lilac to reduce height. Lat year it was 3 feet taller, with the flowers out of reach. I'll take of a few of the taller stems this year as well. It might be a good time to do so now, with the flowers kept as bouquets.

This shrub was probably 15 feet tall, maybe more. It was more tree, than shrub.

When open, this will have white edges on magenta flowers.

Old fashioned lilac-colored lilacs.

This was the first. It's oversized for the location, so after blooming will be pruned back, and root pruned, in anticipation of transplanting.

Kitchen garden log. Tomatoes, potatoes, eggplants, and lemons.

Tomatoes and peppers. They are now spending their days outside in the sun, but brought inside at night. Still under 50 F at night, so too early to plant. Tomatoes require 50-degree F nights, and Peppers require 55-degree. Interesting to note, thermometer in barrel planter shows 60-degrees soil temp overnight. I might do an experiment with one of the peppers, planting it in the barrel and covering it at night. We'll see.

Potatoes are growing. The last ones to start were on the shadier side. The warm sun makes a difference.

The eggplants were the slowest to get started - still not ready for individual pots, but now both varieties have sprouted and some are on their second leaf (first true leaf). It's still early, so I think they should be fine.

Not sure what to do about this. Meyer lemon, basically neglected it all winter, in south window, dry. Most of the leaves fell off. Then it bloomed, and now has lemons. It's on the deck now, made it through a 31 degree night.

Oncidium plants from backbulbs

The 3 little plants in front of the larger one, are starts from backbulbs taken last summer. I used the "sphag & bag" technique, which involves no more than placing the severed backbulbs in a zip-lock bag containing moist (not soggy) sphagnum moss, and leaving it in a bright but not full-sun location. I had them on an East-facing windowsill.

As time passed, each sprouted new growth. Wide range of when this happened, from about a month to about 6 months. The fastest one came from 2 connected backbulbs, and was the youngest as well. I do admit to watering the psuedobulb itself with the "weakly weekly" diluted plant food that I feed the other orchids with, thinking that some of the minerals may be absorbed into the plant indirectly. This watering has occurred only since the pseudobulbs were removed from the sphanum ziplock bags. Each had almost no roots at the start.

Now they are all growing, and putting out roots as well as top growth. Fun project.

Close up of the parent plant. It did not bloom this year. What I thought was a flower spike, was a new pseudobulb. I may have given it too-good care. Certainly, the 2 most recent pseudobulbs are the largest, with the most leaves, compared to any prior ones. Maybe I should neglect it a bit more.

I enjoy watching the new roots sprout and work their way down into the bark mixture. Almost like they would in nature.





This appears to be an Oncidium, but who knows? From Wikimedia Commons here. Original from Source: Nordisk familjebok (1907), vol.7, Till art. Epifyter. So, it's about epiphytes. I like how it shows the plants in their original ecosystem.

"Day Off". Orchid Blogging.

Repotted one of the Paphiopedilum plants. It turned out to be two plants in one pot. I was disappointed, because instead of one robust plant, it was 2 smaller plants. Even so, I guess it means a additional acquisition. They were not identical - one has more mottled leaf appearance. They are now in the same potting mix as my other orchids. As terrestrial orchids, they'll need watering a bit more often, but I like this mix. I sprayed the leaves with neem after potting, to give them a little protection. It also give the leaves a healthy-looking satin glow.

My photos were blurry, so here are some 19th century lithographs instead.

English: Lawrence's Paphiopedilum var. viride(1896)Source Lindenia Iconographie des Orchidées via wikimedia commons. It looks like these were originally classified as Cypripedium, but the appearance is clearly like the modern Paphiopedilum Maudii hybrid.

I'm surprised at how much these look like the modern hybrids.

Paphiopedilum superbiens, originally labeled as Cypripedium. Same source of illustration.

Update:
This is how the repotted Paphiopedilum plants look now. I wanted a record here for future reference.

Orchid Lithographs

These old lithographs are genuine treasures. They were published at a time when growing orchids was a hobby for the wealthy, who could grow them in their own greenhouses. The key as to which orchid is what, is here in Wikipedia.

Epiphyte house at Knypersley-Bateman



The above lithograph is by Ernst Heinrich Philipp August Haeckel , a German biologist, this photo 1860 from wikipedia.
Haeckel and his assistant von Miclucho-Maclay Canary Islands, 1866. From Wikipedia, "an eminent German biologist, naturalist, philosopher, physician, professor and artist who discovered, described and named thousands of new species, mapped a genealogical tree relating all life forms, and coined many terms in biology, including phylum, phylogeny, ecology and the kingdom Protista. Haeckel promoted and popularized Charles Darwin's work in Germany and developed the controversial recapitulation theory ("ontogeny recapitulates phylogeny") claiming that an individual organism's biological development, or ontogeny, parallels and summarizes its species' entire evolutionary development, or phylogeny." Which is still taught today. Also typical for learned men of his time, he had generic ideas that we now rightfully consider racist. I like to think that, if he lived today, he would have seen those ideas as profoundly flawed, while expanding on his evolutionary studies.

I especially like the illustrations that show the entire plant, roots, stems, leaves, and flowers, such as this Laelia speciosa by Bateman, in 1840. This drawing is one of my favorites, showing the roots attached to a branch, and the elegant form of the plant and its flower.

Oncidium micropogon, from Curtis's Botanical magazine, 1887. A typical drawing for the series. These drawings could be used to identify the plants, even today, as well as a photo. Somewhere, I read that the flowers resemble local bees, and that on seeing them tremble in the wind, a bee becomes agitated and attacks the 'foreign invaders'. This attack leads to transfer of pollen, ensuring the next generation. I don't know if this scenario is accurate, but I do see the resemblence.

My collection contains one plant similar to this variety, but the 'bee mimicry' is less obvious.

Oncidium longicornu, also from Curtis's Botanical magazine, 1842Any variety that I grow will doubtless be a hybrid, and also doubtless much easier to grow, compared to these freshly collected species plants. Even so, it's possible that my plants could be descended from these.

Dendrobium nobile, from John Lindley's Sertum orchidaceum (1838-1841). Also from wikipedia, "It is one of the 50 fundamental herbs used in traditional Chinese medicine, where it has the name shí hú (Chinese: 石斛) or shí hú lán (Chinese: 石斛兰)."

Orchid Blogging

On Friday I received the new Blc. "Ports of Paradise" Emerald Isle, mentioned in previous blog entry. Beautiful plant, nice condition. Learning from prior failure-to-repot, I turned it out of the pot on Sat. am and repotted it in a glazed orchid-type pot with plentiful holes in the sides for air exchange. The majority of the roots looked great. All of the leaves were nice. The original medium was not rotted or soggy. Nice plant! Pic is an old lithograph, I believe that was from 1840s.

I learned from gardenweb and internet sources, that waterspots can be cleaned off from orchid leaves using lemon juice. I just used lemon juice directly from a lemon-juice squeeze bottle, and wiped the leaves with paper towel. The leaves look clean, but not the super shiny leaves that result from leaf polishes. Nice info to know!

I also looked for information on growing Dendrobium nobile, since I have 2 specimens. It seems they should do well here, just need to know when to water, when to feed, when to leave outside, and where to put them. It appears that the most important aspect is lots of sun. Today was high 60s outside, and overcast, so I set the dendrobiums outside for a while. Only about 3 hours, I didn't want them to sunburn. From my reading, looks like they need generous water and feeding until August, then change to low nitrogen feeding and cut back watering. Keep outside until nights drop into the 40s. Then keep dry until they show signs of growth again. Something like that. And as much sun as they can get, especially during Summer growth. Even direct sunlight, as long as they are watered frequently and not allowed to get sunburn. Scheme is from Yamamoto Dendrobiums, click for more readable scheme and better explanation.

19th century print of a Dendrobium nobile. This is a cool arrangement - instead of a round plastc pot (plastic wasn't invented for, say, another hundred years), it's sort of a box or bonzai pot, with a tree-branch-like structure and moss, and the dendrobium growing as if in nature. I like the smaller number of flowers - some modern plants seem too lavish. I spent a fair amount of internet time determining that my plants were this species.

My Buddy Charlie

Charlie is a difficult photo subject. He is so excitable, it takes many photos to get one decent shot. He loves to shake hands. Pink Cherry blooming in background.

Kitchen garden. What's ready? What's getting started?

Radishes are ready in the barrel containers. Perfect timing! When they are gone, it will be time to plant the peppers. Greens as well - taking both to work tomorrow for lunch salad.

I couldn't be happier with how the barrels turned out this year. After 9 years of trying, I finally know how to grow radishes here! It's about time, they are supposed to be the easiest vegetable to grow!

The mesclun and scallions in the barrels are also growing like gangbusters. Also, spinach and lettuce. This is great!

Tomato plants had their first outdoor excursion today. The already seem a little more stocky. Probably my imagination. Getting off to a fast start this year.

Peppers among the tomatoes. Growing nicely, but stems are a bit lanky and weak. I hope they improve with more time outside. Probably started too early, then with dreary days, not enough light in the South windowsills.

Most of the seedlings. Will set outside again tomorrow, if the temp is mild. Not in full sun, since I'll be at work.

What else -
First potato barrel with potato plants sticking their noses through the medium.
Scallions, lots of them from starts off from the Egyptian Walking onion. Growing them in the barrels was perfect! I debated keeping them, now glad I did.
Apples blooming - including Golden delicious, which is in its first year of significant blooming. Cool!

Chives too - this is the 5th or 6th batch of garlic chives. Great chopped and scrambled with eggs, too?

In the front yard, those Yellow Potato Onions that I planted in, what, December? are growing nicely to. I didn't kill them after all. Peas are groing, but most didn't germinate.

Cattleya walkeriana alba

After promising myself that I would not add additional orchids after the last mentioned order, and especially from the grocery store, I walked past the orchid display at Trader Joes yesterday at lunch, saw the usual suspects, nothing jumped out at me. Then this one. Very nice in the store. I lost skepticism for about 15 minutes and bought it. Based on multiple web pics, it's Cattleya walkeriana alba, a Brazilian species, not a hybrid. Small size, wanders across the pot rather than being vertical. Likes the dry side.

Immediately on getting home, I unpotted. What a mess. There were actually 2 plants, but one with tiny pseudobulbs, and one small broken leaf. The other with the flower. There was a small vestige of original bark medium, but mostly soggy sphagnum, and about half of the roots were rotted.

I removed the old bark and sphagnum, trimmed off the rotted roots. I dipped the roots in a diluted solution of Dip'n'grow, a plant hormone that is used for rooting cuttings. That is a practice that some growers use for plants that need stimulation of rooting. I don't know if it will help. Then repotted in the same commercial medium that I've been using.

Then I noticed this leaf. I hope this is just an old leaf, and bad growing practices. And I hope it's not a sign of virus infestation. I looked at many web pictures of virus infestation, and most don't look like this.

I sprayed with neem, and this morning sprayed with a foliar feeding of dilute orchid food, same as the weakly weekly food. We'll see how they do, and I'll avoid using tools or containers for other plants, which is a good practice anyway

It's a nice little plant, and the flower is very nice as well, white with a pale green center. Interesting citrus fragrance. I hope it survives, grows, reblooms, and doesn't turn out to have virus. And it will be nice if the 2nd tiny plant grows, so I have one to share (You know who you are!).

Orchid blogging

It's been chilly and rainy all week. Not much to do outdoors - today I did mow the lawn, such as it is, for the first time.

The orchids came via UPS on Friday. See prior posting. The plants were in great shape, I'm very impressed with the appearance of the plants and with the care given to the packing. Hausermann orchids.

The link displays this Brassolaeliocattleya

The variety is "Ports of Paradise" Emerald Isle. Fragrant. May bloom twice a year.

I do not have room for more orchids, but I placed an order for a small one of this variety. I don't know how it will do here, so better not to spend too much. Something might have to go, to make room for it.

I repotted one Potinara and the Vaughnara. They were well potted. The Vaughnara was spilling out of its pot, and looks like it has some active growth, so it seems like a good moment to do so. The Potinara probably didn't need repotting, but I wanted to have it in a container with openings in the sides for better drying between waterings.

I also repotted the cymbidium - this had tough, healthy appearing roots encircling the medium in the container, difficult to separate. I also repotted a Phalaenopsis and a Paphiopedilum. In both cases, I realized that I should have repotted them on purchase. They had been grown in excessively moisture-retentive medium, then potted up in bark mix, then wrapped in spagnum. As a result, there were rotted roots. I cleaned them up, removed all old medium that I could, and potted into the new bark mix. We'll see.
