Friday Fabulous Flower - St. John's Wort


Mid-summer is sort of a slow time for our gardens, so we do prize those plants that flower in July and August.  Two species of bushy St. John's Wort grow in our gardens, both sort of evergreen, flowering at exactly the same time.  The very bright yellow flowers are a great favorite of all the local bees, both in terms of number of visitors and diversity of bee species. And it's easy to see why.  How many anthers are there?  Botanists will count to 10, but after that it's just "many".  Just one pistil (sort of right center) but lots of stamens, a powder puff of pollen.  This is from the larger flowered species, Hypericum prolificum, it is not quite hardy at this latitude and portions tend to die over winter, but then new plants pop up now and again, so never had to replace it.  H. kamianum seems to be hardier; it is a smaller shrub with smaller flowers and can fit in almost anywhere.  

Friday Fabulous Flower: hyssop with hawk moth

This is just a hyssop, a cultivated member of the mint family, but boy do pollinators love it.  Just by a bit of luck TPP happened to catch one of them in action, a hawk moth, a miniature  humming bird of the insect world.  This one is quite typical of what we usually see.  The body is a bit over 2 cm long and nearly as big around as my little finger with a nice greenish fuzzy coat with couple of dark bands on the abdomen.  The wings move too fast for the average phone camera,but caught one of the clear and black wings at the end of a stroke. This one was quite engrossed in visiting every flower available.   At any rate it makes the average flowers just a bit more fabulous.  Enjoy.  

Some botanical culture

TPP is going to pass along this information.  In particular some of these illustrations are just fantastic and in general they are more appealing, more informational, and more beautiful than almost any photographs.  Yet people seem quite entranced by photographs.  The exhibit is called: Out of the Woods: Celebrating Trees in Public Gardens.  Examples of some of the illustrations can be found at this link, so if you find yourself near the Huntington, you might consider a visit.  

Another endangered orchid - How Showy

This Friday Fabulous Flower is one of the grandest (fabulous?) orchids in North America, the Showy Lady slipper, Cypripedium reginae, and yes, you shall get no location information to accompany the image.  Besides this is a wetland species (knee got wet getting this image), and TPP has found this species growing in ditches in Wisconsin.  This species is also a big plant for an orchid; clumps can be large and waist high.  It surprises people to learn that orchids are generally small flowered.  It amuses us to watch people walk right by most orchids because small and green just does not attract much attention. Loss of habitat (if this image had a sound track you could hear cars and trucks whizzing by on a nearby interstate) and human predation are its biggest problems leading to an endangered or threatened status.

Little gems - native plant refuges

Over the weekend the Phactors attended the annual gathering of our state's native plant society along with about 50 other like-minded souls.  The field trip trek we selected took us just across the border into Gary Indiana where we sought native plants in the shadows of post-apocalyptic industrial ruins. Places bounded by railroad yards, interstate highways, and crumbling remains of heavy industry.  You would not think this a likely place for finding uncommon native plants, but you would be wrong.  Here and there tucked away are a few leftovers of the Pleistocene, bits of sandy ridges and watery swales left behind by the receding of Lake Michigan.  The primary problem with small places is controlling invasive  plants and protecting what is left from undue human intrusions.  As a result these places are not labelled, not improved for visitation, and generally hard to find.  Fortunately we had excellent guides familiar with these sites. TPP was professionally interested to see lots of Castilleja growing among Pedicularis canadensis, both are hemiparasites, but they do not grow similarly and do not seem to have the same impact on the surrounding plant community.  Unfortunately these places are well outside our  travel range to be used as research sites.  At some times it was difficult to walk without stepping on yellow ladyslipper orchids that were almost done flowering only to have showy ladyslippers flower in their stead.  Beautiful to see with the background noise of trains and interstate traffic.  The very unexpected diversity of these sites and their general boggy, mosquito-haven nature, only crazy botanists would go there vibe helps keep things safe.  The image is a late flowering yellow lady slipper, Cypripedium pubescens.

Friday Fabulous Flower - New native in the garden


Sorry, sorry, for being so late. TPP was too busy hanging out with a group of native plant enthusiasts to do a FFF.  More on the field trips later.  TPP cannot remember where he saw this plant for sale, but it is rather unusual, and never having seen it in the field, it still seemed like a good idea to plant a couple last year and see what happens.  As you may remember, our yard has lots of shade, and supposedly this species hands some shade, and happily it survived our nasty winter and began flowering in late May.  This is Spigelia marilandica, Indian Pink, and it is a member of the Logania family, not one you are probably familiar with.  But in flower it sure is cute.  It seems to do better in light shade, next will be to see how much is spreads. It is a native species, just not around here.  

Friday fabulous Flower - rebound flowering


New front steps required that a foundation landscaping bed get redone.  A thread-leafed Chamaecyparis had out grown the space and needed to be replaced.  In the process a couple of Oenothera macrocarpa plants were uncovered, and they have responded to the release from light competition by flowering like crazy with as many as 30 flowers per day and these are big flowers and most people don't notice the long floral tube.  Yes, this has been a FFF before, but promise, the next entry will be something different.
