What’s Doing the Blooming? Hardy Hibiscus!

Fri, 07/22/2016 - 1:20am
Hibiscus ‘Heartthrob’

Hardy Hibiscus? In Minnesota? Oh yes!!! These amazing perennials turn heads, and drop jaws from mid to late summer and up until frost. Dinner plate size flowers in shades of red, plum, pink, burgundy and/or white appear seemingly out of no where in July on 4-5′ tall plants. Their showstopping floral display may have a tropical feel, but these amazing plants are hardy from zones 4-9.

Hibiscus ‘Cherry Cheesecake’

Hardy hibiscus thrive in full sun. They perform best in moist, well drained soil.  Regular watering produces the best floral display with larger flowers and fuller foliage. These fast growers are one of the last perennials to emerge in the spring so be patient.

My Woodland Garden – July 21st

Thu, 07/21/2016 - 9:41pm
Cimicifuga racemosa

There are two large shade perennials in the gardens that are standouts this time of year.  Out at the end of the hosta garden anchoring that corner is my Cimicifuga racemosa.

Cimicifugia racemosa

Growing to a height of 4′-5′ and 3′ wide – this large perennial has just started to blossom.   Graceful, slender white flower stalks wave above the foliage.  It is a zone 3 plant and has been residing here for almost ten years now and is just as vigorous as ever!  Providing a different texture alongside the hosta it gets its share of attention.

Aralia Sun King Aralia Sun King

I’ve touched on my Aralia Sun King in previous posts, but it is absolutely stunning right now.  It is now late July, and it is still a gorgeous bright lime green.  Another perennial to anchor a perennial garden.

We have many planters around the yard, and it is at this time of the year that I take out my notebook, make notes on the locations of certain planters and what plants are “winners” this year and that I want to repeat.

Dragon Wings Begonia

I have a file on the computer with planter pictures that I pull up in April, refer to my notes and make my shopping list.  The Dragon Wing Begonias are a repeat each season, and the blue planter pictured here has been in a new location each of the last 3 seasons.


On your planters, it is now very important to continue your fertilization program for your annuals.  They are under lots of stress right now with the heat and humidity so adequate water and fertilizer are so important.  You’ll be able to keep them looking fantastic right up until frost!

The hummingbirds are keeping us amused again this summer.  While sitting on the deck, they dive bomb each other and get pretty darn close as they chase each other from the feeders.  We have had this woodpecker at the feeder for the past three weeks.   The hanging baskets and planter boxes full of begonias are also providing nectar for the hummers.  They are also favoring the hosta flowers right now.  It is such a treat to be delighted by this little creatures.  Summer just is too short!

Successful Summer Planting

Fri, 07/15/2016 - 6:36am

Summer planting success made easy!  Successfully plant trees, shrubs and perennials in mid-summer.  First, liberate the root system that has been trapped in a plastic pot by vigorously root pruning the matted roots with a razor sharp utility knife.  This allows your new landscape plant to root out properly and extremely quickly.

Secondly, water just enough and never too much.  Many people over-water their plants unintentionally.  At Knecht’s, we provide a very helpful and specific watering chart to every customer to enable you to apply just enough and never too much water, along with a handy planting guide.  The secret is small amounts of water on a schedule.  It takes only a few seconds per plant each time.  Literally only a few seconds!  It’s easy.

The days of mid-summer are long and newly planted additions to your landscape use all that daylight to quickly establish lots of new roots.  Works out great for the plants, and it’s easy for you.  We provide all the how-to details in printed handouts when you make your purchase.  You too can enjoy easy summer planting success!

What’s Doing the Blooming? Daylilies!

Fri, 07/15/2016 - 12:12am
Hemerocallis, Daylily Calico Jack Hemerocallis, Daylily Pardon Me

If ever you are looking for a hardy, low maintenance, long blooming, fragrant, and versatile perennial for full sun to part shade you needn’t look any further then the “humble” daylily. Their reliability amazes me year after year.

Hemerocallis, Daylily Primal Scream Hemerocallis, Daylily Passionate Returns

The dependable floral display of the very popular, Stella D’Oro, is often the image of daylilies that comes to mind. But, there are seemingly hundreds, if not thousands, of varieties of daylilies to consider, and this makes them anything but common!

Hemerocallis, Daylily Big Smile Hemerocallis, Ruby Spider

While each variety will perform slightly differently, in height, color and bloom, all daylilies share these basic, fantastic traits… They have the ability to grow in just about any soil conditions, they thrive in full sun to part shade, they can be divided every 3-4 years in either the spring or fall and they are not a favorite of rabbits. Try daylilies in mixed beds and borders with sedum, coneflower, monarda and perennial geraniums.

My Woodland Garden – July 14th

Thu, 07/14/2016 - 8:31pm

Some of the “yellows”.  We have many plants that blossom with yellow flowers – or have yellow / light green foliage.  The golden yews are still sporting yellow foliage at their tips, the Golden Shadows Dogwood is just as striking today as it was when it was first leafing out this spring and we are anxiously waiting because over the next few days – the Goldsturm Rudbeckia are going to be in full blossom.


The Ligularia is showing off it’s tall yellow flower stalks.  A great shade perennial when you are wanting a taller accent plant.  Combined in the garden with hosta, hydrangeas, and heucheras, we have wonderful color and texture combinations.

The Ligularia in the picture below is in a garden with a Bleeding Heart which is an early spring bloomer.  Above the Bleeding Heart we have a Forsythia tree – yellow blossoms


and another spring bloomer.  Now that they are just displaying their foliage – we have the Ligularia coming into bloom.  When it is done, the hydrangeas will be showing off!

There are many varieties of LIgularia – with varying heights and there are some with maroon foliage.  They definitely need part shade to close to full shade.  If they get alot of sun, they will appear as if they are wilting.  They do like moist – well drained soil.


In my newest garden along with the hosta, we have a Lemon Lace Elderberry planted.  A yellow shrub with airy lacey foliage.  It anchors this bed.

I was excited to see a few of my lilies survived the munching of the resident doe.  They are such happy flowers.  We look out the window and it’s like they are looking up at us!

My Woodland Garden – July 8th, 2016

Fri, 07/08/2016 - 7:32am
Hosta Casualty

There were two tornadoes in Rice County Tuesday night, an F0 that went a little north and east of us, and an F1 that went two miles south of us.  This means that the winds were a swirlin’ here in our woods.  I have leaves, twigs, branches and large branches all around so it’s a dose of mosquito repellent  and long sleeves and a few hours to clean up the yard.

My plants were not without casualties – one hosta at the end of the garden took a branch on and lost.

Then, we have a resident doe that thinks she can come in the yard for a midnight snack.  It has been amazing that she has not eaten one hosta.  None.  She did take off two blossoms from one, but in walking the yard again this morning – out of nearly 800 hosta in the yard – none have been munched on.  Because – she prefers the perennials.  My large bed with the most sun we have our garden phlox – they are full lush looking plants – without the blossoms.  She has nipped them all off.  Another dose of “anti-deer” tricks tonight!  We use a variety of methods – human hair,  Shake Away coyote urine pellets, and one of the easiest – I take our little rat terrier out with me and Cooper leaves his scent all around – most years that has been the best in keeping the deer out.

Sedum – 6-1-16

We are always testing plants – here in the woods, Can we do a plant that says full sun.  We have been pleasantly surprised in a few that have been major successes.  A classic perennial – upright sedum – is one of my favorite sunny area plants in that you have interest the entire season.  The foliage in the

Sedum – 7-8-16

early part of the season and then when the flower heads start to set, it provides interest and then in late summer and fall when it blooms it ‘s beautiful.  If you do not prune it back in the fall but wait until spring – you then have the opportunity for winter interest.   However – we have found that it grows nicely for about 3/4 of the summer season and then without enough sun – it gets leggy and sprawls to the ground.  This year, in late May, I put a tomato cage around it in hopes that it would stay more upright.  Pictured here is a shot from June 1st and then this morning.  It has filled in nicely and the tomato cage is hidden.  Now we wait until September to see the end result!

Hardy Hydrangea Shrubs

Fri, 07/08/2016 - 7:13am
Hardy Hydrangea

Hardy Hydrangea shrubs really are able to endure our Minnesota winters and still provide breathtaking blossoms every summer.  Even in Ely, Virginia, Hibbing and Duluth, not to mention southern Minnesota!

Incrediball Hydrangea Blossom

Many varieties of the hardy paniculata hydrangeas are available such as Limelight, Vanilla Strawberry, Firelight, Zinfin Dol, Pinky Winky, Quickfire, Strawberry Sundae and more.  Compact varieties such as Bobo, Little Lime and Little Quickfire.  These shrubs have rated sizes of 3 feet to 8 feet tall and are easy to control because you can prune them back as much as you want in fall, winter or early spring and you will still get a very nice batch of beautiful blossoms the following summer.

Start of Hydrangea Blossoms

A few varieties have already started to blossom such as Quickfire Hydrangea and Bobo Hydrangea.  The other varieties will follow in succession throughout July and August and blossoms stay beautiful for two months – or even more.  There are few problems with the hardy hydrangeas and they are pretty easy to care for.

We have hundreds of hardy hydrangeas in stock and ready to plant, so stop in to get an eyeful of lovely summer blossoms that will last well into the fall season.  Few other landscape plants blossom for such a long time in our northern tier states.

What’s Doing the Blooming? Garden Phlox

Fri, 07/08/2016 - 12:44am
Garden Phlox

The large, vivid pink, neon orange, coral, purple or white flower clusters of tall garden phlox are filling sunny perennial beds and borders with a lovely sweet fragrance.

Tall Garden Pholx First Editions Grape Lollipop

Garden phlox are long lived and hardy perennials. They thrive in well drained, average to rich garden soil. If your soil is particularly heavy, gravely or sandy, the addition of compost or manure will be necessary to ensure proper soil conditions.

Tall Garden Phlox First Editions Coral Creme Drop

Phlox benefit from regular watering, especially during periods of high heat or drought. Plant them in full sun, avoiding fences or walls where air circulation is poor or reduced, and keep the foliage as dry as possible. Taking these steps when selecting a location for garden phlox will help to reduce or eliminate potential disease issues like powdery mildew.

Tall Garden Phlox Bubblegum Pink

Most varieties grow to be 18-30” tall. Check out First Editions Grape Lollipop, Coral Creme Drop, and Bubblegum Pink for some knock-your-“phlox”-off color and improved disease resistance.

Awesome Ornamental Trees

Fri, 07/01/2016 - 8:19am
Phantom Hydrangea Blossom

Would you like to add an ornamental tree to your landscape that produces beautiful blossoms tat last 5 to 10 times longer than most other ornamental flowering trees?   Would you also like it to have a modest size that is easy to control?   Would you like this ornamental tree to be largely free of disease and pest problems?  Would you want an ornamental tree that blossoms at a time of the growing season when almost no other ornamental trees are in bloom?

If you answered yes to any of these questions , a hardy hydrangea tree may be a great fit for your landscape.  Most people maintain hardy hydrangea trees at sizes between 5 and 10 feet wide and tall.  Varieties currently available are Quickfire Hydrangea tree, Limelight Hydrangea tree, Pinky Winky Hydrangea tree, Phantom Hydrangea tree, Tardiva Hydrangea tree, Pink Diamond Hydrangea tree, and Vanilla Strawberry Hydrangea tree.

Phantom Hydrangea Tree

Quickfire Hydrangea is normally the first of the hardy hydrangea trees to produce blossoms, usually in late June.  Good numbers of medium size round blossoms emerge a nice white on the Quickfire Hydrangea tree, and over 4 to 5 weeks, gradually change to a deep pink, staying vibrant for two months or more.

In mid-summer Phantom Hydrangea trees produce monster pyramidal white blossoms that are so lush it’s hard to believe they are real!   Like most of the other varieties of hydrangea trees, these immense blooms gradually take on some pink shades.

Late summer finds the Tardiva Hydrangea trees pushing lovely and large cone-shaped blossoms that have a very nice upright presentation.  I love my Tardiva Hydrangea tree partly because its blossoms are fresh looking from late August all the way into mid-October when blossoms of other varieties have faded.

Come in and check out our hardy hydrangea trees.  At any time during the growing season, we usually have 4 or 5 varieties in stock and ready to add some dazzling and long lasting flowers to your landscape.

What’s Doing the Blooming? Astilbe

Fri, 07/01/2016 - 12:48am
Astilbe ‘Delft Lace’ Photo Courtesy of Bailey Nurseries

When presented with the question, “Do you have anything that will grow in some shade, that isn’t a hosta?” I excitedly tell them all about astilbe! Astilbe thrive in part shade, and make excellent companion plants to wide leaved hostas. They provide soft dark green mounds of lacy foliage and produce strong stems in June and July that hold their panicles of flowers upright above the soft foliage. Astilbe come in a wide range of lovely colors from red to purple, pink to white, and different sizes, but all of them grow best in part shade, with average to rich garden soil.

Astilbe ‘August Light’

The Achilles’ Heel of the disease resistant astilbe is lack of water. Regular watering will keep your astilbe looking fabulous all season long. Next time you’re in, be sure to check out my favorite variety, ‘Delft Lace’. It forms a dense clump of deep green foliage with red edges and matures at about 24” tall and wide. The flowers emerge a soft pink from deep pink buds. It’s a beauty!
