Plants

… But now, in spring, the buds,
 flock our trees. Ten million exquisite buds
tiny and loud, flaring their petalled wings,
bellowing from ashen branches vibrant
keys, the chords of spring’s triumph…
The song is drink, is color.  Come.  Now. Taste.
-Camille Dungy

Perhaps no landscape plant evokes more nostalgia toward spring than the common lilac, Syringa vulgaris. The genus Syringa is comprised of approximately one dozen shrub and small tree species. These are all native to Asia or southeastern Europe and are members of the olive family (Oleaceae). (more…)

My magnolia tree is going mad!

what delicious blossoming:

on branches bare a month ago

this blush, first flush of Spring,

on limbs unburdened by their weight

not buds, but birds, burgeoning:

rose-pink breasted, moon-white crested

fledglings and doting pairs,

there’s no mistaking them

                                –Bet Briggs

The notable plant collector, Ernest Henry Wilson (1876-1930) wrote of magnolias: “Aristocrats of ancient lineage, possessed of many superlative qualities are the magnolias. They have the largest flowers and largest individual leaves of any hardy group of trees. No other genus of hardy or half-hardy trees and shrubs can boast so many excellences…Their free-flowering character and great beauty of blossoms and foliage are equaled by the ease with which they may be cultivated.”

The bold, yet graceful, elegant, yet exuberant, floral displays that both Briggs and Wilson were moved to praise with superlatives happen throughout April at Mount Auburn Cemetery.  As members of the botanical family Magnoliaceae, these are descendants of some of the earliest flowering plants. Fossil remains show members of this family grew in the Cretaceous Period (145-65 million years ago). Before that time, the earth’s surface was primarily dominated with conifers, cycads, ferns, and equisetums (horsetails). Today, the genus Magnolia, includes 85 to 120, deciduous and evergreen species (depending on taxonomic interpretation), primarily native to east and southeast Asia, and eastern North America.  This genus, named by Carl Linnaeus (1707-1778), father of modern taxonomy, honors the French botanist, Pierre Magnol (1638-1715), Director of the Royal Botanic Garden of Montpellier, and professor of botany. Magnol in 1689, published and postulated the concept of plant families, based on morphological characteristics. This was still a time when common belief held that all species came into existence by divine creation.

Our modern, springtime infatuation with magnolias, is due to the large flowers, which can warm anyone’s mood, in spite of our often fickle, early-spring, New England weather. These flowers are actually composed of tepals, a term introduced specifically for magnolias, in 1950, for a floral part that is not clearly differentiated as being either a sepal or a petal.  Many of these tepals may last for several weeks in flower, unless a periodic late frost follows their abundant display. Having evolved before bees, butterflies, or moths existed, these flowers were, and still are, pollinated by beetles, or beetle-type insects.

At Mount Auburn, there are over seventy magnolias, representing 9 species, three hybrids, and 27 cultivated varieties. We will focus here on a few precocious forms, which flower before their leaves emerge.

Magnolia denudata ,Yulan magnolia, is named for its region of origin in China. Its specific epithet, denudata, was given by Linnaeus, and alludes to its being denuded of leaves when flowering, perhaps unusual for such a large flower at that time. This may be one of the first flowering tree used ornamentally, as Buddhist monks have grown it to adorn their temples for the past 1300 years. It was introduced into western horticulture in 1780 by Sir Joseph Banks (1743-1820), an amateur scientist of wealth, who had also served as botanist, on Captain James Cook’s (1728-1779) first round-the-world voyage in 1768-1770. The flowers are a creamy, white color, with 6-9 tepals, that hold their upright, cupped-shape longer than other magnolias. The flowers have a sweet, lemony scent.  There are specimens of Yulan magnolia in the Asa Gray garden, and on Narcissus Path (near Linden Path).

Magnolia stellata, star magnolia, is one of the most beautiful, and popular magnolias. It was first introduced from Japan in 1861 by Dr. George Rogers Hall (1820-1899), a Harvard trained physician, turned trader, who sent living plants from Japan directly to New England. The exquisite charm of these lightly fragrant, flowers lies chiefly in the large number of splayed-open, narrow, strap-shaped, tepals, which may vary from12 to 18, to 40. The color is generally white, although there are cultivated forms with pink tepals. There are star magnolias on Bigelow Avenue, Beryl Path, and Bellwort Path, as well as other locations.

Magnolia x soulangiana, saucer magnolia, is probably the best known and most widely planted of all the magnolias. In Boston, these are the magnolias that line Back Bay’s Commonwealth Avenue.   This is a hybrid, which is a plant with parentage from two different species, in this case the lineage is Magnolia denudata and Magnolia liliiflora. In 1820, this hybrid was created by, and named for, Etienne Soulange-Bodin (1774-1846), a French, retired cavalry officer, turned agronomist. The cup-and-saucer shaped flowers have a pink color outside, but white inside, and generally have 9 tepals.  At Mount Auburn, there are fine examples growing on Indian Ridge Path, Bigelow Avenue, Magnolia Avenue, Asclepias Path, and Willow Pond Path.

Magnolia x loebneri ‘Merrill’, is a hybrid between Magnolia stellata and Magnolia kobus and has fragrant, white flowers, with 10-17 tepals. When mature the ‘Merrill’ is 25-30 feet in height. There is a grand specimen on Spruce Avenue, at Thistle Path, our area known as Alice’s Fountain, as well as several other locations throughout  our landscape.

Magnolia ‘Elizabeth’, was the first light-yellow-flowered, hybrid available. Introduced by the Brooklyn Botanic Garden, the lineage is Magnolia denudata (with white flowers) and Magnolia acuminata (with  green-colored  flowers).  This will become a medium-sized tree.  One is planted at the corner of Magnolia Avenue and Oak Avenue.

We also grow six of the eight “Little Girls” magnolias. These low-branched, and shrubby trees may only reach-15-feet high, spreading to an oval form. All were introduced from the U. S. National Arboretum, and six (‘Ann’, Betty’, ‘Judy’, ‘Randy’, Ricki’, and ‘Susan’) are the result of hybrid crosses between Magnolia stellata ‘Rosea’ and Magnolia liliiflora. “Ann’ has erect, fragrant, flowers, with a deep, purple-red color, and is planted in a small triangular bed on Cherry Avenue. ‘Susan’, has narrow, goblet-shaped, fragrant, flowers of the reddest color, and is found nearby in another triangular bed on Cherry Avenue.  ‘Betty’ has large, eight-inch, violet-colored, flowers, with 12-19 tepals, and is on Cedar Avenue.  ‘Randy’ has 9-11 red-purple tepals, which fade to a rich pink color, and is planted between Cedar Avenue and Cypress Avenue. We do not grow ‘Judy’ or ‘Ricki’.

 ‘Jane’ was a cross between Magnolia liliiflora ’Reflorescens’ and Magnolia stellata ‘Waterlily’ and has fragrant, red-purple, flowers and is found in the same triangular bed, already mentioned, as ‘Susan’, on Cherry Avenue.  Lastly, ‘Pinkie’, the latest of these hybrids to flower, has the palest flowers, and can be found on Juniper Path.  These “Little Girls” magnolias were named to honor U. S. National Arboretum secretaries, or staff wives and daughters.

 Let us whir with the golden spoke-wheels

Of the sun.

For tomorrow Winter drops into the waste-basket,

              And the calendar calls it March.

The scientific definition of the beginning of spring occurs with the vernal equinox (March 20). But, locally, we have experienced snowfall on the running of five Boston Marathons (1907, 1908, 1925, 1961, and 1967) and two Boston Red Sox games in Fenway Park were snowed out on April 8th and 10th in 1996. Boston had a half-inch of snow on May 10, 1977. This year, we place great hope in Lowell’s poetic weather prognostication. For many of us, the lovely sights of the first flowers opening from bulbs are our own “signs of spring”.  Flowering bulbs, corms, and tubers, which are modified perennial, herbaceous plants, are currently coming up in numerous locations, throughout our landscape.

…you are so little

you are more like a flower

who found you in the green forest

and were you very sorry to come away?…

Although small in stature Cephalotaxus harringtonia, Plum yew exceeds yew in ornamental quality. It has beautiful, glossy, dark green, evergreen needles, one-two-inches long. It is another genus that normally has male and female reproductive flowers on separate plants. The clusters of male strobili (flowers) appear on the underside of branch stems in April and are a yellowish-green color.  When successfully fertilized separate female plants will produce a fruit containing a single seed surrounded by a purplish, flesh, which leads it to resemble a primitive olive.
