The lonely Ilex family

Ilex verticillata Red Sprite

I have been working in the industry a long time, and I have come to look at some plants as... lonely. Lonely maybe isn’t the word, but underappreciated isn't the correct word either. The sparkling Stellas and Endless Summers of the world are not lonely plants. Even plants like Clethra and Fothergilla are not lonely plants.

I do think of all Ilex as lonely but I think of the verticillatas - Michigan Holly - as the loneliest. They seem lonelier than glabras (Inkberry) for some reason. Unlike their loved big brothers who are evergreen with classic holly leaves, the verticillatas are considered old fashioned and without much flair. BUT LET ME TELL YOU! There are some new cultivars and hybrids on the market, and they will make you wish all Ilex were deciduous because, “The berries are where it’s AT!”

Ilex verticillata Berry Heavy

Berry Heavy® Red

The older varieties like  ‘Winter Red’ and ‘Sparkleberry‘ are awesome when the leaves drop and the best berry display is in view. But these older varieties can get a little leggy and out of control if they are not maintained. The older cultivars also have men in their lives that get unruly after a while - go figure!

There are several breeding programs that excite me.

Ilex verticillata Berry Poppins

Berry Poppins­®

  • Berry Poppins®: How about heavy berries, (read COPIOUS) on a 4' tall dwarf plant, perfectly sized for the landscape. The berries are large and an orange-red in color. The leaves also drop a little earlier than other hollies for a longer display. The pollinator is... are you ready? Mr. Poppins®. 
Ilex verticillata LIttle Goblin Guy

Mr. Poppins®

  • Berry Heavy® Red: bred for better bearing (copious again) and even longer persistence. The berries are bright red and nicely bunched along the stem. This one will reach 6-8’ in height. The pollinator is again, Mr. Poppins®. (He does get around, along with his friend 'Jim Dandy' who can help out with the pollination duties.) There is also a gold-berried version, Berry Heavy® Gold.
Ilex verticillata Berry Heavy Gold
  • Little Goblin® Red: this is a 4’ dwarf with extra-large red berries. Her pollinator is Little Goblin® Guy. There is also a orange berried variety in the Goblin series.
Ilex verticillata Little Goblin Orange

Litte Goblin® Orange

We are not always appreciative of new plants. Does that make them lonely? My opinion on these plants is that anything to bring the poor Michigan Holly into the spotlight is good. But I have also been watching these new varieties for a couple of years now and these are good plants and a welcome addition.

P.S. Part two may be on all the cool and awesome new Inkberry cultivars...

Roast me!

Employee of the month

As the shrub and perennial investor at Christensen's I rarely get to go outside to meet and greet. Now while we are socially distancing for COVID-19 it is even worse. When I do get outside, I can’t tell the difference between employees and customers. It was bad enough with hats and sunglasses, now there are masks! And just before the shutdown happened I was about to get new glasses... So currently six feet is a little far away for me. Pardon me if I don't recognize you!

Carts and customers

I decided to try and use this column to get some feedback. Do I get it right? (Did I get it right in this mess?) Please! This is a Roast Me – did I get it wrong? Go ahead - I can take it!

hydrangeas marked sold

What plants am I missing in the nursery? We NEVER want you to be caught short on plants that you need, so please let us know what you want and when you want it.

You are welcome to yell at me – however it is best to yell at your salesman. Then they can get it ordered for you. (It would be much better for me if you yelled at them. They are scared of me and usually bring me gifts like cookies and such with your orders! Isn’t that sweet of them!?!?)

Contact information for all our sales staff can be found in our app and on our website. And, you can send me your feedback here: rothk (at) christensensplantcenter (dot) com.

ITOH peonies

I know that as a woman of my age, grace, natural beauty and talents that it is next to impossible for me to get it wrong. But that age thing sometimes makes me forget things.

P. S. You cannot roast me on that last paragraph!

New for 2020

Sedum Atlantis

Who's ready for a for a sneak peak of 2020? I have been very busy getting ready for next year, and I thought this was a perfect time to spill some of my excitement over to you. As the nursery industry moves forward, we here at Christensen’s want to move forward as well. So allow me to introduce you to some of the new stuff out there, as well as maybe a few older items that will be new to us.

(In no particular order)

Physocarpus Summer Wine Black

Physocarpus Summer Wine® Black: Ho-Hum... just another dark leafed Nine-Bark. Nope! These guys clearly stand out and make a mark. The foliage is so much darker and slightly shiny. They stood out across 3 large nursery blocks of plants!

Thuja Tater Tot and Mugo Slowmound

Thuja occidentalis Tater Tot®: The name alone makes it a must-have! I really like the look of this one. Although a dwarf (reaching 1-2’ tall) it is considered a faster grower than a 'Hetz Midget' or 'Danica'.

Pinus Mugo var. Mugo ‘Slowmound’ and ‘Enci’: Although not new to the world these will be new to us. ‘Slowmound’ will eventually reach 4’ tall, but it will take 20-40 years to do so. The ‘Enci’ (which has a normal mugo growth rate) will only reach 2-3’ tall. (As a comparison, a “Mugo” will reach about 20’ tall and P. m. ‘Pumilo will reach 5’ tall)

Sedum Atlantis

Sedum takesimense ‘Atlantis’: This one is getting awards from all over – so I had to sneak in what few I could this fall for some division work. I honestly don’t think there are any left as I think the employees around here now have them in their own gardens! I am on the hunt for more! It is a medium sized (6-10” tall) Sedum with incredible serrated cream variegated leaves tinged slightly pink. I am guessing it flowers but who cares.

Ilex verticillata Berry Heavy®

New Ilex verticillata? Really?? Yep! I am sorry to all the ‘Red Sprite’ aficionados but I have found a new love affair. Ilex verticillata Berry Heavy®. It is a fall and winter showstopper! Huge masses of red berries are spectacular. Also new is Ilex v. Little Goblin® Red: It has extra-large reddish orange berries on a dwarf 3-5’ tall plant. (Both can be pollinated by ‘Jim Dandy’.)

Ilex Little Goblin Red

Ilex verticillata Little Goblin® Red

Andropogon gerardii ‘Blackhawks’: Another WOW! This Bluestem emerges deep green to dark purple in the late spring. As the summer progresses the grass gets darker and darker, finally ending up nearly black by fall. At about 5’ tall and very upright this grass looks best en masse. PS Did I tell you that it also has awesome red-purple flowers to sway in the breeze?

I am saving the rest for next year’s surprise!

Sunbathing hosta?

Hosta 'So Sweet'

Of all the questions I get about growing hosta the most common one is: which varieties will take sun - and how much sun is too much sun? Many shaded areas get SOME sun and choosing the right varieties for the conditions will be the difference between success and...

Maybe we won't talk about that.

All hostas prefer to have morning sun and maybe some late afternoon sun. It is that midday sun that is the challenge. Sun tolerance, is to some degree, leaf-color related.

Hosta 'Guacamole'

Hosta 'Guacamole'

Most hosta with whitish variegation will burn in hot afternoon sun. Those that have more green to chartreuse variegation will handle some of that midday sun as long as they are getting plenty of water. You should avoid putting blue hosta in the sun as the blue color is a waxy coating on the leaf and will melt off, turning your blue plants green. Golden hosta WANT sun. If they don’t get enough sunlight they will turn that sickly greenish-yellow chartreuse color. You know the one. Green hosta will typically take some midday sun, and I have found that the thicker the leaf the more sun they will take.

Hosta 'Vulcan'

Hosta 'Vulcan'

Do you have a shady area that merges into a more sunny area and looking for some continuity? Here is a list of sun-loving hostas to fill in the sunny areas. Remember, soil moisture is key to keeping the plants looking good.

'August Moon'Golden, medium to big size
'Avocado'Green with light green center, big size
'Fragrant Bouquet'Green with chartreuse edge, big size
'Francee'Green with white edge, medium size
'Ginko Craig'Small green with white edge, groundcover
'Gold Standard'Gold with green edge, medium to big size
'Guacamole'Light green with dark green edge, big size
'June'Gold with green edge and streaking, big size
'Paradigm'Gold with wide green edge, medium size
'Patriot'Green with white edge, medium size
'Paul's Glory'Gold with green edge and streaking, big size
'Prairie Moon'Gold, big size
'Royal Standard 'Solid green, medium size
'So Sweet'Green with cream edge, medium size
'Spartacus'Green with rippled gold edge, medium to big size
'Sum and Substance 'Lime-green, very big size size
'Vulcan'White with green edge, medium size

Ten fall favorites

Fothergilla

...and I don't mean cider or donuts. No, it's COLOR TIME! 

Mums. Burning bush. Maple trees! You can probably name a dozen fall color plants without even thinking about it. But what about choosing from some of the lesser-known plants that also shine every autumn? Here are my top ten favorite fall color plants that may not be on your radar.

Hydrangea quercifolia

Oakleaf Hydrangea

  • Hydrangea quercifolia and cultivars: The large, rough-textured leaves are especially striking as they turn shades of red and purple every fall.
  • Viburnum x juddii: Beloved for it's sweetly-scented spring flowers, this medium-sized shrub has great burgundy-purple fall color accented by blue to black berries.
Itea

Itea

  • Itea virginica cultivars: This medium-sized native shrub deserves to be planted more often. The orange, red and burgundy fall color is outstanding and is extremely long lasting.
  • Epimedium cultivars: An underused perennial tolerant of dry shade that gets brilliant red to purple fall colors.
  • Amsonia hubrectii: This North American native perennial grows to about 3x3'. The fine, feathery foliage turns a striking golden-yellow in the fall.
  • Clethra alnifolia ‘Hummingbird’: Usually planted for the amazingly fragrant flower spikes in mid-to-late summer, this smallish shrub turns a gorgeous golden yellow each fall.
Fothergilla

Fothergilla

  • Fothergilla ‘Mount Airy’: This is a handsome 3-5’ shrub that gets wonderful fall color in hues of red-purple, orange and yellow.
  • Amelanchier: OK, so this one is not that obscure but it has to be in my top ten.
  • Vaccinium hybrids: These ericaceous shrubs (best known are blueberries) will surprise you with their beautiful red-orange fall color.
  • Panicum virgatum cultivars: ‘Shenandoah’ and ‘Hot Rod’ are two that turn beautiful red or burgundy.

Brilliant options for fall color

Helenium

Fall is in the air. Hard to believe, isn’t it? Where has the year gone? It is almost time to start planting your bulbs, raking the leaves and fall cleaning the beds. Today I want to talk about plants that we don’t typically think of as being for fall.

We regularly think of mums, aster, burning bush, and trees like Sugar and Red maple as plants we like for fall interest. Lesser known options might be 'Autumn Joy' sedum, Japanese Anemone, and 'Little Henry' Itea.

Solidago

But let me tell you about some others! Solidago (Goldenrod) with it's bright yellow flowers, Fothergilla with it's burnt orange, red, and yellow leaves, and Chelone (Turtlehead) with it's pink turtle-head-shaped flowers.



Don't overlook Caryopteris - it's blue flowers begin late July and continue into September. This small shrub can be treated like a semi-woody perennial and benefits from cutting back low in the spring.

Chelone
Caryopteris
Helenium

My all-time fall favorite is Amsonia hubrichtii (Bluestar) - the Perennial Plant of the year in 2011. The foliage turns bright gold and at 2.5’ in the back of the border it stands out like a mini-sun. Some turn red-orange, bronze, purplish and yellow, and all are spectacular.

Another favorite of is Helenium, which grows 2-3’ tall. Also known as Sneezeweed, they bloom in a mix of delicious fall colors - yellow, browns, and red. They typically start blooming in late August and continue well into October.

Mums are great, but there are a lot of options for extending color from summer into fall. 

I would feel guilty if I didn’t at least mention Viburnums. They come in so many shapes and sizes and with different colored berries in the fall, how can you go wrong? But wait, there’s more... almost all of them get great fall leaf color. This massive genus of shrubs alone would allow you to have flowers from spring to late summer and then berries and fall color until the snow flies.

Viburnum lentago

Well sorry, but gotta go. This article gave me a great idea for pumpkin carving and I want to go get some cider and donuts and draw it out on paper!

Why plant annuals?

Kims petunias

Annuals? Why!

I know I am the perennial lady and so bad mouthing annuals should be a full time job for me! However I am not here to bad mouth them, I am only here to find out why you would want to plant them?!? I have asked around for answers and I just don’t think the answers I have received are of much merit any more. I have heard “They flower all year”, “They have such awesome colors and patterns”, “They are easy to maintain”, and “They are bulletproof”. The first two reasons could be true, the last two are not! Even if they were all true, annuals are very expensive (even if your customer is paying the bill – no one has ever been able to retire off planting annuals alone) and very labor intensive (at a time of year when you can make a better margin off other plants).

New breeding in perennials has made many of the “annual” reasons obsolete. Why would you plant annual salvia instead of a perennial salvia? Same awesome blue color, both need deadheading to reflower after a rest period. Let’s compare Coleus to Heuchera. Both plants are grown for their foliage and both prefer a little shade. Check out Heuchera ‘Fire Alarm’, ‘Caramel’, or ‘Snow Storm’. Not only do they have spectacular foliage year after year but they also have pretty flowers to boot! Never let those Coleus flower – because that is sudden death. There are many options in the perennial department to choose from – all with lots of color that last all year long. Why not try Geranium ‘Rozanne’, G. ‘Azure Rush’ or G. ‘Blushing Turtle’, Campanula ‘Blue Waterfall’, Dianthus (any of multi-hundreds to choose from), Lavender (perfume of the Gods) or how about some of these dwarf Buddleias?

Petunia Midnight Sky

I have to be honest and tell you up front I went to a local Garden Center this weekend and bought – GASP- some annuals! I succumbed to this awesome annual Petunia called ‘Midnight Sky’. I fell in love with it because I like that speckled look. You can tell I like that look because my garden is filled with perennials like Heuchera ‘Marvelous Marble’ and ‘Midnight Rose’, Pulmonaria 'Mrs Moon’ and Brunera ‘Jack Frost’. I am going to plant it right off the deck and enjoy if for as long as possible. It will die soon, as I don’t water my plants! Perennials, they really don’t mind it too much – but annuals, well they can’t live without a constant watering. How many of you have heard from your customers that all those succulent Begonias just suddenly – out of the blue, died. All the while, they swear they watered them every day!

I want to leave you with these three thoughts: 1: Ageratum for Butterflies? You haven’t seen Butterflies until you planted Echinacea and now it comes in every color in the color wheel and, the newer ones are rock hardy, 2: Hellebores? Try and find an annual that blooms when there is still snow on the ground, 3: I am desperately looking for Petunia ‘Frills & Spills Damson Ruffle' – help!
