Early Spring Bloomers

Posted on Tuesday, April 18, 2023 · Leave a Comment 

I like to have blossoms in the garden and in vases everywhere. I try to have something blooming all the time – or as often as possible. Right now, in mid-April, I count more than ten species of plants in bloom, along with seven species of bulb plants which are blooming by the hundred for me.

 

Leatherwood

Let’s start with trees and shrubs – what I call woodies. The most unusual woody is leatherwood (Dirca palustris). This is a native woodland plant that does well in part shade. Although the literature says it prefers moist, rich soil, I have it in dry soil and it does well there.

 

Leatherwood has small greenish-yellow flowers that appear about the same time as forsythia –mid April for me. Mine is slow growing with lovely gray bark that reminds me of beeches. This is a well-mannered, slow growing plant that stays 3- to 6-feet tall and wide.

 

February Daphne (Daphne mezereum) is in bloom now with highly fragrant pinky-purple flowers. It is originally from Europe, Turkey and Iran. I love it so much I named a corgi after it (she is now gone, alas). It stays 3-5-feet tall and wide. In the fall it has produces small red berries.

 

I named a dog after this shrub, Daphne mezereum or February daphne

Magnolias are in bloom now, too. My favorite is the Merrill magnolia, a hybrid which produces double white, lightly fragrant flowers. I planted mine as a small tree in 2004, and now, 19 years later, it is about 40 feet tall with a spread of 25 feet. It blooms reliably (nine years out of ten) on my birthday, April 23. It is a good specimen tree to put in a lawn, and will do well even if the soil is consistently moist to soggy.

 

These magnolias come as both single-stem and multi-stem trees, but most are multi-stemmed, as mine is. However, when the stems get big they grow together at their base. Sometimes the included bark rots and weakens the stems, making them susceptible to splitting. I removed one big stem on mine two years ago and the tree has recovered.

 

Forsythias are in bloom everywhere with bright yellow flowers. If yours only blooms down low, in the area covered by snow, the buds which were formed last summer were killed by the winter cold. So get rid of it and buy a new variety such as New Hampshire Gold, Vermont Gold or Meadowlark. All are hardy throughout New England.

 

Drumstick primroses

My favorite early spring perennial is called the drumstick primrose (Primula denticulata). It comes with flowers in purple, blue, pink, magenta and white. The florets are small and arranged in 2-to 3-inch globes on 6-inch stems. They do best in moist to wet soil in sun or partial shade.

 

Hellebores or Lenten Roses (Helleborus orientalis) are also wonderful spring flowers. Mine have been blooming for a couple of weeks already and will continue on for another month or so. The blossoms are 5-petaled and 2- to 3- inches wide with yellow stamens in the center. Colors range from white and cream to pink, purple and nearly black. They are evergreen, but last year’s leaves should be cut off now as they are all bedraggled.

 

A dainty flower with beautiful finely-cut foliage is a spring ephemeral called corydalis or fumewort (Corydalis solida). It pops up in my garden where it wishes, and I am always glad to welcome it. It seems to do best in moist, part shade with rich soil. The flowers on mine are small, long-spurred light blue, but other colors are also possible. There is a yellow variety of a related species (C. lutea).

 

Corydalis solida

Lungwort or pulmonaria (Pulmonaria spp.) is a good ground cover that is blooming for me now, too. It is interesting that a single stem might support blue, pink or apricot flowers all at once. All do well in shade or partial shade and better in moist soils than dry soils. It spreads by root.

 

There are at least a dozen different species of pulmonaria including P. longifolia with spotted leaves and multicolored blossoms. The one I like best is P. angustifolia which has very intense blue flowers and solid green leaves. I’ve read that varieties or species with more white spots grow better in full sun than those with fewer or no spots.

 

Wildflowers are starting to bloom, including one of my favorites, bloodroot (Sanguinaria canadensis). These white multi-petaled flowers come up from the soil wrapped in the leaves that look like a green cigar. In cold days, or at night, the blossoms close up but open on sunny days when the bumblebees are working.

 

Double bloodroot is rare and not usually found in the wild but is sold in specialty nurseries

The bloom season of bloodroot is short, but there is double bloodroot which is sterile and blooms for a longer time. Like all bloodroots, the clumps get bigger every year, so you can dig them up and divide them to start doubles in new places.  The sap from the roots is poisonous, so wear gloves when dividing any bloodroots. Do that in now, or in the fall.

 

We certainly deserve spring blossoms for having survived winter and mudseason. But you do have to plan and plant for those early bloomers.

Trees and Shrubs for the Shade

I grew up in a small town in rural Connecticut. Behind the house there was a brook and a hardwood forest with a high canopy of old maples that created a cool space for spending hot summer days. My favorite understory tree was a small, bushy tree that had very fragrant leaves and stems, which I decided must be witch hazel, as the barber splashed witch hazel on my neck after each haircut, and it was vaguely the same. I frequently chewed on the leaves and green twigs in lieu of the chewing gum that was forbidden to me.

This summer I discovered the name of that plant: spicebush (Lindera benzoin). One of my gardening clients had requested one for her garden, and as soon as I crushed a leaf, I was transported back 60 years. I knew it immediately. Most winters my part of New Hampshire drop to minus 25 degrees Fahrenheit, so any plant that will survive here must be rated for Zone 4 (Minus 20 to minus 30). I checked my favorite tree book (Michael Dirr’s Manual of Woody Landscape Plants), and sure enough, spicebush is rated for Zone 4. I will get my own as soon as I find the right place on my property to plant it.

From Dirr’s book I learned that spicebush can get to be up to 12 feet tall and wide, and is in the laurel family. There are 80 species of Lindera, both deciduous and evergreen (L. benzoin is deciduous). Apparently it blooms in early spring but the yellow blossoms are only one fifth of an inch across, so not overwhelming (I have no memory of it blooming). Fall leaf color is yellow. Dirr’s book says it does well in moist, well drained soils in full sun or half shade, though in my experience it will do well in dry shade in open woodlands. Dirr says spicebush is not often found in nurseries, but E.C. Brown’s Nursery in Thetford, VT has several nice ones.

Another woodland plant that I would like to try is leatherwood (Dirca palustris). Like spicebush, this is a native shrub that will grow in shady areas but this one prefers moist to wet soil – and I have plenty of that. Apparently it only gets to be 3 to 6 feet tall and wide, and is more open and spreading in shade than in sun. It is has small yellow flowers that bloom very early in the spring, well before the leaves emerge. Native Americans used the bark to make bow strings, fish lines and in the manufacture of baskets. Tough stuff.

Calycanthus-or-sweetshrub

Three years ago I planted a sweetshrub or Carolina allspice (Calycanthus florida). The first 2 years I grew it in full sun with deep, rich moist soil. Both years the leaves yellowed – as if the sun were too strong and bleached them out. So last fall I moved it into a grove of old wild apples that provide full shade, and it seems to be doing much better. It is blooming now, and has put on considerable new growth.

Sweetshrub grows to be 6 to 9 feet tall with a 6 to 12 foot spread. Some varieties have very fragrant flowers, but mine is not. Dirr’s book suggests buying the shrub is in bloom in early summer, as the fragrance varies from plant to plant. It is adaptable to acid or alkaline soils, and is hardy to Zone 4.

Mountain laurel (Kalmia latifolia) is another fabulous shrub that will grow in deep shade (or even full sun), and I have grown it these past 20 years or so, even though I am on the northern edge of where it is successful. Mine produces delicate three-quarter inch diameter flowers, cups of white with pink veins. After cold winters I don’t always get flowers. There are cultivars with flowers in white to rose, and everything in between. Definitely buy when blooming. It does best in acidic soil that is cool and lightly moist. I have seen it growing abundantly in the wild at Sleeping Giant State Park in Hamden Connecticut, where there is a high, dry, open hardwood forest.

Climbing hydrangea on barn wall

Of all the shade-growing woody plants, the most dramatic on my property is the climbing hydrangea (Hydrangea anomala subsp. petiolaris). I have vines that completely cover the north side of my barn – and that only get a few hours of sun each day. It is in bloom now, with flower corymbs (flat topped inflorescences) that have both fertile and sterile (showy) blossoms and are 6 to 10 inches across.

Climbing hydrangea is slow to get established – mine took 6 years – but once it begins to grow, it quickly covers a surface. It will attach itself to stone or brick, but needs to be strapped onto wood surfaces, at least at first. Mine has grown through the cracks on the barn and is now self-supporting. Its vines can grow 60 feet or more, and has support arms for its flowers that reach straight out from the barn that are up to 3 feet long. It is truly dramatic.

So don’t despair if your property is mostly in the shade. There are these plants, and lots more, that will amaze and delight you.
