Saucer Magnolias in Central Park

Saucer Magnolias (Magnolia x soulangiana) are related to some of the oldest angiosperms (flowering plants, as opposed to gymnosperms, or conifers). Some members of the magnolia family are found in fossils that date back to 95 million years ago. Magnolias co-existed with dinosaurs, and survived the extinction event that marked the end of the prehistoric creatures.


Magnolias were the first flowers and were not pollinated by flying insects, but instead by beetles. That's why the seed cones are so rigid and tough (to protect them from the large, chewing bugs). In fact, it was not until after flowers evolved did insects and other pollinators co-evolve to match a food source.


The plant below, the Saucer Magnolia, was not one of these ancient flowers. This is instead a hybrid of M. lilliflora and M. denudata. It's popular for it's large, fragrant flowers that burst open as soon as it gets warm enough.



The magnolias behind the Met in Central Park are the best looking ones I can find in Manhattan, if not the entire city. They sit on this hillside and, with their neighbors, the Crabapples, provide spring color from April until mid to late May. There's nothing quite like going for a run or a bike ride when these are in bloom and catching a whiff of their scent on your way up the hill.

Sophora japonica

Actually, the Genus Sophora has been replaced with Styphnolobium though, for sentimental reasons - and the fact that most people in the nursery trade still do - I like to stick with its older name. The common name is Japanese Pagodatree or Japanese Scholartree. It's one of the loveliest street trees, as it has flowers in the summer, persistent edamame-like pea pods (it's in the Fabaceae family) and adequate yellow fall color.

You see this tree all over New York City. Usually they reach about 40-50 feet in height, with a caliper of 10-12". However, in the Jardin du Plantes in Paris, I saw an 18th Century specimen that was just a wee bit larger:


The water bottle gives you an idea of how wide the trunk is - my best estimate was 5' or so.


The plaque dated the specimen as planted in 1747 :

I looked a little ridiculous to the other people strolling the gardens - taking dozens of photos of this tree, mouth agape. In my bad French, I tried to explain to one Frenchman how unusual it is to see this tree at this size. He was mildly, politely, impressed.

Grape Hyacinths in Union Square


Muscari armeniacum is tucked into the planting along the east-west path that is an extension of 15th street. However, they are very easy to miss. I love this bulb - it's fragrant and multiplies and looks great en masse, but this is not the best spot for it. In a raised park like Union Square, it'd be better used along the edges of the park, where it would be eye level with passersby.


PS- Even if you don't know Latin, it should be easy to break down the meaning of this plant's name. Muscari : Musc is Latin for "fly" but this plant was probably called such due to it's musky odor. Armeniacum refers to the plant's native habitat of Armenia.
