Lady’s Slippers

Pink Lady’s Slippers Flowering

pink lady's slipper2   223Pink Lady’s Slippers (Cypripedium acaule), also known as Moccasin Flowers, differ from Yellow and Showy Lady’s Slippers in two fairly obvious ways. One is that the stalk the single flower is borne on bears no leaves. In addition, the pouch, or labellum, has a vertical slit running the length of it, rather than an oval opening on the top. Bumblebees are the only insect strong enough to push their way through this slit and are their main pollinators. In New England, almost 25% of the Pink Lady’s Slipper population have white flowers (see insert).


Yellow Lady’s Slipper Flowering

5-30-13 yellow lady's slipper 063There are only about three short weeks in the late spring when the blossoms of Yellow Lady’s Slippers grace our woodlands and wetlands. The production of an orchid is a complicated process. If pollination and fertilization are successful, hundreds of thousands of some of the smallest seeds of any flowers are scattered by the wind. The seeds of Yellow Lady’s Slippers (and other orchids), unlike those of most flowering plants, contain no food for the seedling plant. In addition, the coating surrounding the seed is extremely tough, so much so that the seed can’t germinate until Rhizoctonia fungi digest the outer coating, which allows the inner seed to access soil nutrients. This can take two years or more and then it may take another few years for the plant to produce a flower.


A Great Christmas Present!

If you’re looking for a present for someone that will be used year round, year after year, Naturally Curious may just fit the bill.  A relative, a friend, your child’s school teacher – it’s the gift that keeps on giving to both young and old!

One reader wrote, “This is a unique book as far as I know. I have several naturalists’ books covering Vermont and the Northeast, and have seen nothing of this breadth, covered to this depth. So much interesting information about birds, amphibians, mammals, insects, plants. This would be useful to those in the mid-Atlantic, New York, and even wider geographic regions. The author gives a month-by-month look at what’s going on in the natural world, and so much of the information would simply be moved forward or back a month in other regions, but would still be relevant because of the wide overlap of species. Very readable. Couldn’t put it down. I consider myself pretty knowledgeable about the natural world, but there was much that was new to me in this book. I would have loved to have this to use as a text when I was teaching. Suitable for a wide range of ages.”

In a recent email to me a parent wrote, “Naturally Curious is our five year old’s unqualified f-a-v-o-r-I-t-e  book. He spends hours regularly returning to it to study it’s vivid pictures and have us read to him about all the different creatures. It is a ‘must have’ for any family with children living in New England…or for anyone that simply shares a love of the outdoors.”

I am a firm believer in fostering a love of nature in young children – the younger the better — but I admit that when I wrote Naturally Curious, I was writing it with adults in mind. It delights me no end to know that children don’t even need a grown-up middleman to enjoy it!


Showy Lady’s Slipper

Classified as imperiled in New Hampshire, vulnerable in Vermont, rare in Maine, endangered in Connecticut and down to 14 sites in all of Massachusetts, the Showy Lady’s Slipper is the highlight of every June for those in the Northeast who are lucky enough to live near a spot where it grows. The rarity of this orchid is attributable to a lack of suitable habitat, as well as the browsing of white-tailed deer. Showy Lady’s Slippers are typically found in fens, a type of wetland which is not as acidic as a bog. Because it reproduces mostly by underground rhizomes (even though one flower may produce a half-million seeds), it often occurs in clumps, giving the false impression that Showy Lady’s Slippers are abundant. According to Minnesota’s Dept. of Natural Resources, where Showy Lady’s Slipper is the state flower (but also very rare), it has a long life span — some may live as long as 100 years.


Yellow Lady’s Slipper

Yellow lady’s slipper, Cypripedium pubescens, is in flower in central Vermont/New Hampshire, gracing woodlands and bogs with its beauty. This plant has what is called a mycorrhizal association, a relationship with a fungus that colonizes its roots. This mutually beneficial association provides the fungus with carbohydrates from its host plant, the yellow lady’s slipper, and enables the yellow lady’s slipper to have increased mineral absorption due to the fungus’s large surface area. More than 90 percent of plant species are believed to form a symbiotic arrangement with beneficial soil fungi.
