Garden tip - Control of Japanese beetles

Although a bit late this year, and a fairly modest crop, the Japanese beetles have arrived.  Here's relatively easy & inexpensive nontoxic means of control.  Depending upon what you wish to protect.  Buy several yards of bridal veil netting.  You can attach it to branches or fences or support cages or poles using clothes pins (pegs).  This works for all types of beetles and even things like cabbage looper butterflies. However remember with squash and cucumber you have to give bees access or do your own hand pollination.  Since we only have one hill of cucumbers, and a handful of zucchini plants, hand pollination each morning is not a big deal.  The ladies in fabric stores are always amused by my veil purchase.  If you are fairly gentle you can use the beetle netting two years. And of course this means you don't need any nasty chemicals.  Although some critter tore up a bed of beans having become tangled in the netting. Most of the beans will survive but the netting not so much.  

Friday Fabulous Flower at the fruit stage


Found this fruit in our woodland garden the other day, and it is a bit unusual.  Everyone's first thought is raspberry, and this is the same type of fruit derived from many pistils in the same flower, an aggregate fruit. 
So technically each unit is a fruitlet partially fused to its neighbors.  But this type of fleshy fruit is not common in this family (buttercup).  The leaf may not even help you identify this plant as it is not common here abouts, and it gets collected destructively for use as a medicinal and in many areas it is over collected.  This is Hydrastis canadensis, goldenseal.  How did you do?  Ever see this before?  The flower is constructed along the lines of last week's FFF, no showy perianth but lots of showy anthers around a number of pistils. 

The weirdness of birthdays as you get older

Mrs. Phactor just "celebrated" her 70th birthday.  TPP did this some months back, so we can claim a cumulative 140 years, and it's hard to know exactly  what to feel.  Neither of us looks or feels ancient, and yet TPP thinks he's the first male in his lineage to live this long.  Neither of us has any threatening health conditions that prevent us from pursuing the  things we like.  Gardening is both our hobby and our exercise program, although we are committed to more travel.  A big old garden like ours always provides plenty to do.  This may not be your idea of retirement, but our gardens are quite important to us, and they can always be improved upon.  Hard to know exactly how to feel, and actually most of our friends in our Friday Seminar group are older, but not necessarily wiser; we're the kids so to speak. Actually many set a good example.  70 seemed old when it was the older generation. Now it doesn't seem so old, although Mrs. Phactor says I shouldn't buy any more little trees because they take so long to grow. Got a stick for a 50th birthday present, and now this Magnolia salicifolia is quite large for a 20 year old tree.  

Friday Fabulous Flower - Here's all the anthers.

Midsummer is an interesting time for our gardens.  Lots of lilies of all sorts for color, but then several white flowered species.  But the queen of the shade gardens is this black snake root (lots of common names, but it is not a well-known plant here in the upper Midwest) (formerly Cimicifuga racemosa, now Actea racemosa just as good old Linnaeus proposed).  The tall (5'+) branched racemes of white flowers show up very nicely in the light shade it prefers.  The flowers have no sepals or petals, just a cluster of a hundred or so stamens surrounding a single pistil.  The odor is described as a sweet and fetid, to which TPP adds musky, and it attracts an array of pollen foraging insects: flies, gnats, beetles.  Although a bit hard to get established, the plants are tough and long-lived. This is a member of the buttercup family which has a number of species whose flowers only have anthers.  

Waterlilies


The weather of late has been close to hot; and humid.  Not everything likes that kind of weather.  The lily pond has stayed pretty full because of all the rain (3.6" in the last event).  And for some reason the waterlilies (Nymphaea) are doing very well.  These flowers are totally gorgeous what with all the flower parts, and while not favorites with everyone these white waterlilies are very white and with the contrasting leaves and water, they are wonderful.  Actually this image is very similar to a water color painting of waterlilies that we bought on line quite a few years ago,  TPP actually found the painting while searching for images of waterlilies.  Enjoy!


Friday Fabulous Flower - pond flora

Wow the long weekend sent by very fast, so Friday comes early this week or late last week.  Who cares?  So you may never have looked closely at this particular native plant because you likely would get wet and muddy getting close.  This is not such a problem for a lily pond if the damned four-legged mammals would stay away and quit stomping plants and tipping over pots.  Even the neighbor's young lab got in on the fun.
At any rate the pickerel weed (Pontederia cordata) is still doing OK (the part that didn't get mashed and is looking good).  It is a handsome plant and worth having for some pond edge vegetation and flowers.

Friday Fabulous Flower - Neither grass nor a pink

First of all, TPP has to thank the F1 for buying this plant for a Father's Day present.  Sadly it got savaged by a nocturnal visitor for no particular reason, but raccoons are like that.  The common name grass pink refers to two other plant families and it is neither, so much for common names.  This is an orchid native to this area, Calopogon tuberosa, the generic name refers to the yellow beard. Curiously most orchids are resupinate meaning that their flower stalk twists 180 degrees to turn the flower upside down, however this orchid flower is right side up. The slender leaf is slightly grassy, and the flower is pink, so there you go.

Garden come through - primavera

Some broccoli, a cup or so of snap peas, some asparagus, and for good measure a handful of golden chantarelles, not enough of any one thing but altogether they make for quite a good pasta primavera. And you never ever see chantarelles in a store in the USA, so quite a treat.   

Friday Fabulous Flower - Last Magnolia of the Season

It has been a pretty good year for Magnolias; no late frosts and plenty of rain, almost too much.  When the gardens finally get to June, the Magnolias are just about done flowering, except for the sweet bay, Magnolia virginiana.  In our area this species never grows into a full-fledged tree and generally grows as a largish shrub. Some genotypes have trouble with the winter cold so choose your nursery well, preferably to your north.  Ours does not produce a big floral display, but rather a few flowers at a time, and you are more likely to notice their stunning fragrance than their visual display.  The floral odor is a sort of musky fruity fermenty mix that little beetles just love.

Friday Fabulous Flowers - Calycanthus


These are presently in flower in the Phactors' garden, and according to some they are all in the same genus - Calycanthus.  The maroon  colored flower in the upper left is the Carolina spicebush, C. floridus, which TPP has taken apart for you. The upper right was originally Sinocalycanthus (featured here before) but is now considered part of the same genus (it was hard to imagine an eastern Asian eastern North American disjunction).  And the bottom flower, trying hard to look like a star magnolia, is their hybrid offspring called "Venus".  It's a largish, scrambling type of shrub that flowers like crazy for several weeks.  Another selection has a maroon flower, but the ivory one shows up better.  All three survived a very tough winter.  Enjoy.
