Family’s Rhubarb Mousse Connects Generations

I found this story about rhubarb and a family’s history in my vacation house kitchen cupboard.  It was left behind by friends using the house.  I enjoyed reading it and learned it’s a part of a series written by Chrissy Lavielle to pass down her family’s recipes and their history.  She generously allowed me to share it with you.

I really like rhubarb.  It’s big and dramatic; it looks tropical, but survives sub zero winters and anything else you can throw at it; and you can eat it – it’s the only fruit that’s not a fruit.  My rhubarb plant flowered last summer.  A two-inch diameter club shaped stalk shot up six feet and exploded in a mass of tiny greenish white flowers.  The effect was prehistoric and vaguely ominous.  I watched it carefully, ready with my trusty loppers, in case it got out of hand.

Both my mother and Craig’s mother grew rhubarb.  Craig remembers pretending the leaves were clothes and I remember using the leaves and stalks for everything from flags to parasols.  Mothers now days would never allow this, they know that the leaves are toxic – chock full of oxalic acid.  I guess maybe mom told me not to eat the leaves, because I never did.  Or maybe she didn’t.  Why would you eat a boring green leaf when you could bite into a bright red stalk?  That eye watering, tooth roughening, mouth shriveling bitter sourness is a childhood memory of Cincinnati summers that is hardwired into my brain.

Every February my mother began to look forward to the “spring tonics” – stewed rhubarb and dandelion greens from the golf course.  I wasn’t fond of either one.  Her philosophy on fruits and vegetables was to cook them until they were really, really dead.

Red stocks are the tasty part, the leaves are toxic and bitter.

Red stocks are the tasty part, the leaves are toxic and bitter.

My mother in law’s recipe is a much better way to enjoy rhubarb.  I helped her make it once, and smiled to myself as I watched her cut the rhubarb.  Holding the stalk over the saucepan with her left hand, and the paring knife curled in the fingers of her right hand, she put her thumb on the opposite side of the stalk and cut against it.  Pieces of rhubarb fell into the pan in a quick series of metallic plops.  This is exactly and precisely the way my mother, another Ohio girl who lived through WWII and The Depression, cut up rhubarb.  Neither one of them had any use for a cutting board and to my knowledge, only used one occasionally – usually for cheese.

Mother planted her rhubarb at one end of the asparagus bed.  In the years after she died, the rest of the garden gradually faded away, but the rhubarb plants outlived both my parents.

Rhubarb mousse is one of Craig’s favorite deserts.  He also likes rhubarb pie or pan’d outy – but he is dead set against adulterating it with strawberries or blueberries.

Rhubarb Mousse

1 lb. rhubarb cut in 1″ pieces (3 cups) or 1 pkg.

1/2 cup water, divided

1 cup sugar

1 envelope unflavored gelatin

2 tsps. lemon juice

1 cup whipping cream, whipped

Red food coloring

Cook rhubarb with 1/4 cup water until it strings.

Soften gelatin in 1/4 cup cold water.  Stir into hot rhubarb until dissolved.  Remove from heat.  Add lemon juice and chill until mixture mounds when dropped from spoon.  Fold into whipped cream and mold.

For more information about growing rhubarb see my favorite garden guru’s article, “Grow Strawberries Tasty Companion: Rhubarb” by Vern Nelson at The Oregonian web site.

Rhubarb at market

Buy rhubarb at a farmer’s market and ask them what variety it is and why they grow it.

His favorites are ‘Chipman’s Canada Red’  which is nearly identical to ‘Crimson Cherry’.  ‘Victoria’ is not as sweet but is a vigorous  “do gooder” plant.

Here’s another good source for how to grow rhubarb https://happydiyhome.com/growing-rhubarb/.

 

My guest blogger Chrissy got her plant from her mother, and many people get a plant from a neighbor.  There’s nothing wrong with this method but if it were me looking for a new plant I would go with Vern’s suggestions.

Dwarf Mugo Pine – Get the Right Plant for Your Landscape Design!

The Right Dwarf Mugo Pine Can Be the Perfect Addition to Your Low Maintenance Landscape

For success in the landscape (which I define as “right plant right place”), it’s important to get the exact plant specified by your designer.

Pinus Mugo 'Sherwoods Compact' a client favorite low maintenance landscape plant.

Textured trio of ‘Sherwoods Compact’ dwarf pine, Sempervivum (hen and chick), Arabis (rock cress)

Early in my career I specified three dwarf Mugo Pine.  I wanted a uniform pin cushion shape to contrast with ornamental grasses and succulents.  I wanted the pines to stay small, and contrast with the grasses that would be two thirds bigger. This was my vision.  What happened instead was three dwarf Mugo Pine ‘Nana’ grew into three different shapes and heights!  None of them stayed small.  The fact is plants grown from seeds can be as variable as your siblings.  My brother and I have blue eyes, my sister has green eyes, I’m a redhead my brother a brunette and my sister’s a blonde.

I learned that seed grown dwarf pines are variable, only plants grown from cuttings of a named cultivar could be trusted.  I knew this in theory but the industry was deceptive in labeling.  I now knew to avoid any dwarf conifer called ‘Nana’!  That was a secret code word for seed propagated.

Pinus Mugo 'Slowmound' is another favorite trusted dwarf pine for low maintenance landscape.

Then I was told that ‘Pumilo’ was a named variety and it stayed low.  I was tricked again.  The industry was also using seeds from ‘Pumilo’, not cuttings to produce a more affordable and (profitable) dwarf Mugo Pine. For many years I did not use any Mugo Pine at all, mainly because I was disgusted.

When specific size and shape uniformity are needed always select plants grown from cuttings or tissue culture.  People who work at retail nurseries are sometimes ignorant of these finer points.

Mugo Pine with Hummingbird Mint, Sedum and Lavender

These days I need dwarf evergreens, particularly pines, for my clients because they are true low maintenance.  They are low water, no pruning or candling required, they take hot full sun even next to concrete, and they look great year round.  These true dwarf pines won’t get too tall in 10  years.  So I had to find sources and growers I could trust.

The varieties I use and where I get them:

Oregon Small Trees is a private wholesale nursery/grower.  The owner, Dave Leckey and his daughter, grow all of their plant material from cuttings.  It takes many years to grow dwarf plants to a good size for the landscape.  I also specify plants grown by Iseli Nursery and another resource is Buchholz & Buchholz Nursery.  None of these resources are retail, you have to buy their plants through a plant broker or in the case of Iseli, those plants can be found at Portland Nursery, Cornell Farms and Farmington Gardens.

Notice the fine texture of this needled mugo pine.

Pinus Mugo ‘Sherwoods Compact’ is a favorite of my clients, they love the texture of the needles.  I like Pinus Mugo ‘SlowMound’ a bit better for some designs.  It’s a darker green.  My favorite miniature Mugo Pine is called ‘Donna’s Mini’ and I’ll spend more money to get a larger tiny plant when I use ‘Donna’s Mini’.  It grows less than 1 inch a year in ideal circumstances.

Hellebore Heaven

Hellebore 9

A sample of the many varieties of Hellebore in bloom at the open garden.

If you love Hellebores (like I do) don’t miss this open garden.  The O’Byrne family designs Hellebores and have an international following.  Marietta and Ernie are rock stars in the garden design world.  Their Hellebores will dazzle you with color and form. Plus they are sturdy plants, bred in Eugene Oregon at the Northwest Garden Nursery.

Why go?

First, you’ll have a chance to buy these unusual and fantastically beautiful plants (most are not available locally).  Second, you can buy them in a large 2 gallon size, not in tiny sizes.

Here are Hellebores with drought tolerant Yucca in full sun.

Also see the large sun garden where you will find Hellebores in combination with interesting rock garden plants, succulents and more.  Most people think Hellebores are for shade only.

The garden art is unique, interesting and never overwhelms the garden, something I appreciate in a design.

Open Garden in February

Call a friend and save the date: Northwest Garden Nursery holds an open garden every year, typically the third week of February. Last year I took my sister Donna and her friend (and my client) Sherry.  They are plant fiends and appreciated seeing such a large display of Hellebores. We were not able to purchase any plants, however, because they were sold out! So make sure you go early in the week if you want to make some purchases.

We also visited Greer Gardens and I got to say good bye to Harold Greer who is beyond the rock star status.  His lifetime of work with Rhododendrons and other plants has enriched my designs and my life, so it was poignant to go and purchase a few last plants from him.  I purchased a rock garden plant, Rhododendron kiusianum White Form.  It was exquisite. He has closed his mail order company.  Bloom River Gardens will be trying to fill Harold’s shoes.

Drought tolerant Ceanothus G. 'Hearts Desire' Picture from Xera

California Lilac Ceanothus Griseus ‘Hearts Desire’   Picture from Xera Plants

I’m excited about these new plants for Portland gardens.

Many of us are familiar with California Lilac and its blue flowers.  Beloved by bees, including our endangered native bumble bees, it’s  also a host plant for Swallow Tail butterflies.  However, it has its problems in a home landscape.  Many varieties are short lived because they receive summer irrigation along with your other plantings.  They need infrequent or no summer water to be a long term plant.  Most of all keeping them a manageable size is difficult for many gardeners. Ceanothus Griseus ‘Hearts Desire’ is different.  It can handle some summer irrigation and unlike all the other varieties of ground cover type California Lilac, it grows to only 4 inches tall and grows slowly to 24 inches wide.  It is easy to tip prune so can be confined.  These new habits make it a very useful plant for smaller landscapes.  It can take a lot of dry so we can plant it in the xeriscape dry tolerant gardens that have no irrigation or it can receive some summer irrigation.   I see this  plant as a major improvement over old varieties like ‘Anchor Bay’ or ‘Points Rey’.  Xera Plants is growing ‘Hearts Desire’ but expect other growers to jump on the plant wagon soon.  I’d use ‘Hearts Desire’ under limbed up fir trees, on SW facing banks or in “hellstrips”.  I will be trialing this new variety of California Lilac in my xeriscape garden.

Manzanita is a shrub or large tree known for its colorful bark and picturesque windswept shapes on the northern California coast. Here in Portland it’s too wet or too cold for most Manzanitas.  News flash!  Some of the California Manzanita species have been hybridized (designed by humans) into cold hardy evergreen ground covers and shrubs.  I love the leaves and the bark color and will be using these two specific varieties of Manzanita in my designs more frequently.   My favorite is ‘St. Helena’ which grows to 24 inches, and can take irrigation if it must.

For success with Manzanita don’t feed the soil with compost or fertilizer at all, not even when doing initial soil preparation.  Work with the existing soil.  It needs to be watered through its first summer and then little to no irrigation is best.  This year (2015) my clients will be instructed to water it through its first winter as well since we are expecting a very dry winter but most years this would not be necessary.  Note: hummingbirds love Manzanita flowers.  Pacific Horticulture Society has an in depth article about Manzanita/Arctostaphlylos for the NW; by our revered plants man Paul Bonine.

Callistemon viridiflorus 'Xera Compact' Picture from Xera

Callistemon viridiflorus ‘Xera Compact’ Picture from Xera Plants

Callestemon or Bottle Brush is well known to Californians.  They have many varieties with hot red flowers and they  attract hummingbirds like crazy.  Their loose needles have a tropical feel to them and they can look wild or messy depending on your point of view!  While talking with Greg Shepard at Xera Plants, I got good news about the varieties of this plant that we can grow here in Portland.  A few of these make very attractive  tidy evergreen shrubs.  I’m always looking for soft textured evergreen shrubs with winter good looks that don’t get too big.  Hummingbirds are attracted to all of the Bottle Brush plants but deer are not.  Pretty great huh?

Here are 2 varieties I am most interested in for my clients:

1.  Callistemon Pityoides ‘Corvallis’.  Yes found in Corvallis, Oregon the original plant withstood 20 years of cold and everything an Oregon winter can throw at a plant.  It grows 5’ tall and 3’ wide in ten years.  It can take regular water or can be trained into drought tolerance easily.  It flowers twice in a season with soft yellow bottle brush flowers that remind people of baby ducks.  Deer usually leave it alone unless they are desperate.

2.  Callistemon viridiflorus ‘Xera Compact’ grows to 4 ½’ feet tall.  It is  VERY heavy blooming for 6 weeks.  The flowers are chartreuse and yellow brushes 3 inches long, the leaves are deep green in summer and take on hints of red in winter.

Summer Heather – Perfect for year round color

Summer flowering heather can be easy care

I use heather at my vacation house because it’s so easy.  I’m there once a month, have no irrigation system and I have hungry deer.  It’s got to be a tough plant to make it!  Lots of people buy heather, plant them and they die quickly.  Without knowledge specific to heathers, success is tenuous, but with a little knowledge this is a very tough drought tolerant winner of a plant in my book.  It has year-round beauty, is great food for bees and it can be the evergreen plant that holds a summer garden together visually through the winter.

Planting Tips:

Honey bee on spring heather in Sellwood Moreland garden designHeathers need good drainage but if you have clay soil don’t despair.  Heathers planted on a burmed planting bed or  on a low mound do well.  Heathers are perfect for  sunny slopes.

A designer pal plants her heathers in pure barkdust.  I’ve done this and had excellent results as long as it was on a slope or berm.  Don’t try this crazy bark dust idea in a flat landscape with heavy clay unless you berm up.

Watering well the first year is critical.  If heather plants dry out to the point of  wilting, even just a little bit, they will die.  There is no rescuing it with water and having it “perk up” as many other plants will do.   When the tiny fine foliage wilts or dries the plant stops taking in water with its roots.  Avoid this first year problem and take advantage of the benefits of a fall planting.  You still have to water carefully the first summer after a fall planting but it is not so edgy.

Pruning Tips:

Pruning is important and easy.  The most important year for pruning is the second spring after you have planted the plant.  Prune before new growth starts.  You must trim to just above the previous years wood; trim too much and you will have ugly holes in your plants that may never fill in.  Avoid pruning late in fall or winter.

Calluna -Summer Flowering Heather

Trim too little or not at all and  in a few years you will have an ugly plant with bare wood stems in the center of the plant.  When this happens we can’t simply cut it back severely which we can do with many plants to fix the problem.  Trimming every year before new growth starts (February or March for Pacific Northwest) will keep your plants attractive long term.  Who knew low maintenance was so much work right?  Once you know what to do, you have a plant that will work beautifully for decades with a once a year trim.  That is low maintenance.

Summer heather/Calluna Vulgaris is a great plant for hot sun situations.  This summer for the first time ever, I actually had foliage burn.  They got no water for 45 days in record breaking heat, but since these plants have been there for five years there was not permanent damage or loss.  New plants would not tolerate that amount of drought but mature plants took my neglect in stride.  6 months later there was no sign of any damage.  My kind of plant!
