A modest heat wave has turned a bit cooler, but still no rain for nearly 3 weeks. Plants are very dry. TPP has no choice but to water certain plants. The big-leaf Magnolias, a newish Cephalotaxus, a struggling double file hydrangea. However a couple of well established perennials or biennials were doing surprisingly well: several big blue Lobelias and very red Lobelia. Usually the latter is associated with some moist places, but this plant is just in a typical enough mixed bed. Lobelia cardinalis is just not a plant TPP has much luck with. Recently TPP told you that a Silene was about as red a flower as you can get, but forgot about this Lobelia. And the hummngbirds love it.

A plant pundit comments on plants, the foibles and fun of academic life, and other things of interest.
Gardening during time of plague - Chapter 4
TPP is retired so avoiding the university campus where Covid cases are increasing was not a tough thing; but hanging out at home is getting a bit old. The garden produce is keeping us well fed with fresh tomatoes, sweet peppers, eggplant, and zucchini with lots of basil. Baby bok choi and lettuce have germinated for a fall crop. And again some hot weather and drought have returned. Water bill will be high again.
Home improvement is our means of keeping people working during the ecomomic plague and it is also the season when nothing seen or heard is to be trusted. It's going to be a long fall and TPP is so tired of this administration. Can barely find the energy to say that the WH rose garden needed some work, but who ever did the planning has no sense of the garden aesthetic. Bland would be TPP's assessment. But the current occupants are not the sort of people who have a well developed aesthetic, and certainly this is the least of my concerns. Botany is an international field and TPP is tired of apologizing for our country's bone-headed attitude. Leadership is a terrible thing to squander.
One gets the impression that our government wants us to be afraid, but neither god nor guns makes for safety although some people seem to think so. Stupid conspiracy theories are favorites of the gullible. Saw a well-dressed young gentleman who sign proclaimed that he thought socialism sucks. Personally libraries and public schools certainly don't suck that badly. Hope his graduation depends on his understanding of socialism.
Friday Fabulous Flower - Meadow rue
Well, another busy weekend kept TPP away from his laptop, so the FFF is late again. A few late summer plants are flowering to provide a bit of choice. Perhaps the most visually appealing are the magic lilies, the naked ladies, or whatever you call them are a late summer amaryllis and our gardens have hundreds of them in flower. The leaves come up in the early spring along with the narcissi. But then they die down and provide no hint of the flowering to come. Then in the first week of August, clumps of flowering stems shoot up 30 or so inches tall and bear an umbel of big pink flowers.
Hidden in plain view are lesser flowers, and one of them is a meadow rue, a member of the buttercup family in the genus Thalictrum (the species is uncertain, maybe T. rochebrunianum). The individual flowers are quite small, but the plant bears a spray of hundreds. The colored parts are either anthers or bracts (in this case, surrounding quite a few stamens.). Ours were being visited by emerald green orchard bees.
Friday Fabulous Flower - catch-fly
Today's, yesterday's, FFF is sure to add a splotch of color to your garden primarily because this is the reddest flower we have. It tends to flower just after the mid-summer flowering doldrums, so it's bright red flowers are most welcome. A friend walking through our gardens spotted the flowers and reached over to pull the plant a bit closer, and discovered first hand one of the more interesting common names, catchfly. The entire aerial parts of the plant are covered in glandular hairs making it discustingly sticky. Small insects do get trapped in the goo. This is Silene regia, the so-called royal catchfly. This is as close to a trouble free perennial that you can get.
Friday Fabulous Flower - Mallow
One of the larger and gaudier flowers that you can easily raise is the rose mallow (Hibiscus mosacheutos). Like all related flowers the large number of stamens forms a tube through which the style grows bearing a branched 5-parted stigma. The flowers are huge, 8-9" across, and they are white, pink, rose, or red with red highlights (nectar guides) in their centers. Often this time of year when the rose mallows flower, the Japanese beetles appear and chew the crap out of the mallows and quite a few other plants too, although they do love the mallows. This year for some reason the beetle population is quite small, do little to no damage. These are herbaceous perennials, so they die back to the ground and grow new aerial shoots each year.
Friday Fabulous Flower - Bottle Brush Buckeye
S
pring flowering peters out through June until summer flowering plants sort of take over, but it isn't quite the same. Lots of prairie natives flower in the summer, but not nearly as many shrubs or bushes flower in the summer. Here's an exception, and if you don't have one, you need to rethink your garden. Right now in mid-July, our bottle brush buckeyes (Aesculus parviflora) look great, and they grow OK on edges and in light shade. This shrub has probably the showiest floral display of any shrub that can grow on a light shade border. They can get a bit taller than many people would like, and they do spread a little after awhile but no so much it is considered a problem. These long (over a foot in length) inflorescences just cover the plants and contrast nicely with dark green foliage. Japanese beetles have been a problem before, but hardly any beetles this season. Our plants were seedlings and it was a very slow start, so buying bigger plants, paying someone else to grow them, is a good idea. The plant is a native to SE USA, but they seem quite cold hardy.
Friday Fabulous Flower - Stokesia
Most sources indicate that Stokesia is a type of aster, all this means is that all of the flowers have a bilaterally symmetrical corolla, the flower form that is located around the periphery of daisy-type flowers as opposed to the cenral button composed of radially symmetrical flowers. There is only one species, so TPP suspects that someday someone will figure out its relatives and it will get shuffled into another genus. Stodesia is an honorific name, honoring an early physician who had some botanical leanings, Jonathon Stokes. This plant is native to the coastal plain of southeastern USA, but is a pretty adaptable ornamental, and reasonably tough in both its ability to deal with drought and cold (zone 5). It is a fairly short plant in our experience so it gets used on margins of paths. The flowers come in a number of shades of purple, as well as pink and white. Note the white, t-shaped stigmas protruding from all the central flowers.
Drpught, dry, dry, dry, cracked earth, and hot temperatures
What a great time to be a gardener, it gives us something to do that is pretty low risk for us senior citizens. Our gardens need water, lots of water, and the lily pond too. Oh, things that can be easily watered are doing well enough like boxed, caged tomatoes. But the Phactors do not waste water on lawn, which is on its own. Everything is wilting to some degree, and if it doesn't recover over night then it really needs to be watered the next day. Plants like the big-leafed Magnolias have a lot of surface area and can lose a lot of water. And other things are rather new and as yet don't have extensive root systems, like our newest plum yew and an Abelia, and a white snake root. So a good deal of TPP's daily activity is pulling hoses around to ward off the worst on the drought. Gave an older hose and a soaker hose to the F1 because her whole garden is new. Even now a timer is telling TPP to get going and move the sprinkler to a new area in an attempt to rejuvenate a double-file Viburnum, that is trying to recover from a winter die-back. Already lost a dwarf Metasequoia from the Japanese garden; it has never been a happy camper, so no surprise really. In a real surprise, the prairie nursery TPP has inherieted had some bunchflower blooming (Melanthium virginicum), which TPP has never seen before. Quite handsome. Hope to propagate some more this coming year.
Friday Fabulous Flower - Who's wort?
OK This is a little bit weird. TPP is never a day early with a FFF. Mrs. Phactor pointed out that yellow flowers with lots of stamens is a bit of a theme recently, and all in our front garden. Both the cactus and peony a few posts below fall into that category. This particular flower is an evergreen shrub with a bluish-green foliage. It's quite a handsome plant and the bees just love it. Some species of this genus almost all with the general common name of St. John's wort, are native in our flora, but this one, Hypericum kalmianum, is native to the Great Lakes region, so a bit north of here. Obviously it is quite hardy, and this particular one is an ornamental variety, basically trouble free and much recommended. Ours is about 4 feet wide by 2.5 feet tall.
Gardening in a time of plague: Chapter 3
Summer is upon us, and so is a mild drought. Our city is raising water rates, so it will be getting more expensive to keep gardens watered. It takes a minimum of 1/2 inch of rain a week to keep gardens going. Sensitive plants need more water, some are better at dealing with dry conditions than others. Two senior citizens did manage to distribute 2.5 yards of wood mulch onto gardens and paths to make things look much better. Several plants are candidates for relocation, but until the soil moisture gets better it is a risky undertaking. The Phactors have decided that ostrich fern should be added to the list of never plant this plant. It looks OK but it's rhizomatous and tends to take over whole gardens.
New additions do get preferential treatment when is comes to water. Until they get well rooted you have to keep watering them. Nothing too delicate has been added to our gardens making it pretty easy to keep up. A couple of small hostas are an exception but being small means watering them is not a major project.
A largish patch of Sorbaria, the so-called false Ural spirea, sort of looks like a sumac, but has fuzzy looking plumes of white flowers. It's close to being on the do not plant this plant list; it is a spreader and was threatening to consume a neighbors' garage. The trespassing portion was removed and a couple of hosta were found in the process. Unless you have room for such plants, do not plant them.
At least gardening gives us an outdoor activity and exercise. And weeding helps you maintain a healthy frame of mine, giving the opportunity to get rid of poor choices without getting depressed over politics. The amount of damage one person can do in just 3 years is hard to believe. A niece is getting married in July and in October. The earlier event if just too untimely for us presently and we hope things are better in 3 more months. Sadly this is part of the havoc wrought by this pandemic. And mostly all you can do is to keep the gardeners well supplied with margaritas, a nice self-sterilizing liquid. A few people have visited to have a socially-distanced reprieve to break up the quarantine a bit. It's outside and the gardens are big.
