Pleased Monday GPODers!
Since September of final yr Allyson Levy has been sharing insights, data and inspiration from Hortus Arboretum and Botanical Gardens, the spectacular property that she manages with associate Scott Serrano and is beneficiant to share with the general public (Take a look at earlier submissions: Rising Pawpaws, Particular Fall Vegetation, Fall is for Purple, and Fallen Leaves and Seed Heads). Allyson and Scott use their 21-acre arboretum and botanical backyard in Stone Ridge, New York to maintain native, uncommon and historic plants and encourage others to understand under-loved vegetation. In in the present day’s submission Allyson continues this mission by exploring the fantastic world of magnolias. Whereas a well-loved tree in a lot of the USA, there may be extra to this flowering woody than you think about.
For sure, the magnolia household is arms down one in every of my favorites. Perhaps due to the truth that their ancestral lineage goes again to when dinosaurs roamed the earth, making them really prehistoric bushes, a “dwelling fossil”! Having existed for over 95 million years, they’re one of the historic flowering vegetation nonetheless dwelling in the present day, with their pure rising vary together with japanese North America, Central America, and Asia. Eight species of magnolia are native to the USA.
Magnolias are considered among the most primitive flowering vegetation. Attributable to their historic historical past, these flowers rely upon beetles as their main pollinators, since beetles advanced earlier than lots of the extra complicated pollinators. Magnolias have had an intensive interval to co-evolve with beetles, which has allowed the flowers to retain many primitive traits or diversifications that guarantee pollination by beetles.
Magnolia flowers have petals and sepals that resemble one another so intently that botanists seek advice from them merely as tepals. On the base of the tepals the flower produces a candy substance a “nectar” that lures the beetles in. Floral scent is one other means beetles discover magnolia flowers. Though not all magnolias have sturdy aromas, many fragrance the air with a lemony, spicy-sweet scent, just like the native species sweetbay magnolia (M. virginiana, Zones 5–10) (above), which attracts beetles and each plant lovers and gardeners alike.
One other attention-grabbing anatomical attribute is that magnolia flowers possess powerful carpels, the feminine elements of the flower, advanced to forestall harm from beetle mandibles as they feed on “nectar,” pollen, and just about all of the floral elements. As evening approaches, the innermost tepals shut across the carpel, trapping the visiting beetle, who simply so occurs to deposit pollen everywhere in the flower’s receptive stigmas. Then the anthers turn out to be lively, protecting the identical beetle in recent pollen, so when the tepals open within the morning, the beetle scrambles out and finds one other flower to do it another time. This technique has co-evolved between the beetle and magnolias, which minimizes the danger of self-pollination, which might result in inbreeding and recessive mutations.
The Magnolia flower’s tepals and carpel communicate to the primitive anatomical buildings of this historic genus, as seen in Magnolia macrophylla stunning massive flower.
Maybe essentially the most missed ornamental great thing about all magnolias is their distinctive and extremely decorative fruits, typically referred to as seed “cones,” although botanically talking, they aren’t true cones. The hybrid magnolia crosses have a variety of unusual sizes and shapes; like ‘Golden Solar’ magnolia (M. ‘Golden Solar’, Zones 5–8) (above), which produces among the lewdest-shaped cones, calling to thoughts particular anatomical elements. Magnolia seed cone, generally known as a follicetum have ripe seeds ranging in colour from shiny scarlet to a muted orange-red. When absolutely ripe, the person seeds turn out to be suspended by a tiny thread earlier than being dispersed to the bottom and eagerly taken by birds, squirrels, and different small critters.

The upside-down seed cone of Siebold’s Magnolia could also be small, but it surely provides visible influence to the panorama.
The big and stately seed cone of the bigleaf magnolia is one other beautiful attribute of this prehistoric plant!
Magnolias are particular to me as a result of they had been the primary bushes I ever planted, courtesy of the Mates of the City Forest group in San Francisco. From their tree checklist, I chosen two Southern magnolias (M. grandiflora, Zones 6–10) to plant as a result of I knew in the future they might make grand bushes.
Now, twenty-five years later, my husband and I are co-directors of Hortus Arboretum and Botanical Gardens, a 21-acre stage II accredited nonprofit arboretum situated in a rural a part of the decrease Hudson Valley. Since 2001, now we have planted over fifteen thousand vegetation, and our magnolia assortment is one in every of our most prized ones within the gardens. Our focus is to plant as many uncommon, endangered, and seldomly encountered magnolias as attainable.
Allyson despatched over a lot nice data and exquisite photographs of magnolias, that I’ve break up her submission into two posts. Tomorrow we’ll proceed this deep-dive into magnolias whereas Allyson exhibits us the good range in magnolias they’ve at Hortus Arboretum and Botanical Gardens.
