Friday fabulous flower - Berry pretty, pretty red

 Lately TPP's relationship with the calendar has been quite tenuous but having determined that today is a Friday means finding something fabulous to blog about.  Today is actually the end of the fall semester at the university, graduation day, and a former master's student is getting his PhD today.  It was not done under the supervision of yours truly, and that's OK mostly because he still considers TPP to be his mentor. And that's how TPP knows it's a Friday.

The leaf color is long gone, but two patches of fruit color persist, and as my readers know fruits are flowers at the stage of seed dispersal and the advertising for seed dispersers is what attracts us.  Seriously this is a native plant that will eventually provide meals for migrating birds.  The fruit display becomes dramatic after the leaves fall.  What surprises many people is that this is a holly, and mostly people think that means an evergreen, but this swamp holly, or possum haw, or winterberry is deciduous.  In fact that is also it's latin name Ilex decidua.  You really should find a place, or like TPP several places, in you landscaping for this plant.  Probably the only draw back is that this holly is also dioecious, so you also have to grow some pollinators that will be bare this time of year and the flowers are quite small and do not produce much of a display.  



Friday Fabulous Fruit


Ripe fruit is of course a flower at the stage of seed dispersal.  And one of the nicest "flowering" shrubs in our gardens are the winterberries, which is a holly, (Ilex verticillata).  Now hollies do not have large attractive flowers, but the fruit display can be very vivid especially when contrasted against the green leaves.  Except winterberry is a deciduous native holly, so it drops its leaves leaving the brilliant red berries on display, where they will remain until discovered by migrating cedar waxwings or robins.  Like all hollies winterberry is also dioecious (2- houses), so you need "males" to pollinate the females.  TPP likes to plant a pollinator plant for every 3-4 fruiting plants.  Obviously the winterberries have not dropped their leaves yet, but you can see how bright the red berry display is anyways.  Unfortunately the berries are not edible for the basic human GI tract.  But they look great in a boarder planting.  The shrubs can grow to 3-4 meters tall in wet areas, but seldom get more than a meter or two in drier places.  They are not a finicky about soils as some hollies either.
