The buzz around this year’s Native Plant Sale is building to fever pitch! Our plant sale comes at the perfect time as we have finally emerged from the frigid gloom of an unusually long cold winter to find colorful wildflowers emerging all across the state. These ‘spring ephemerals’ are so-named because they only flower for a fairly short time since they start losing the sunlight once the trees leaf out.

We are fortunate to have a lot of fairly common attractive native plants in Delaware, and sometimes these get taken for granted. This is a pity, as several have some surprises in store if you look at them closely. Trout Lilies are a perennial often found growing in clumps which get their name because their mottled leaves resemble the sides of a Brook Trout, a freshwater fish. However, they take between 4 and 7 years to mature so the great majority of the lilies you see don’t produce a flower and have just a single leaf (top photo). Only the older, flowering plants have two leaves (second top). The beautiful nodding Lily flowers are harder to find but tend to occur in small colonies which are often visited by insects (bottom photos).

The familiar Mayapple has a similar subtlety. This distinctive umbrella-shaped wildflower of shady forest floors is often found in dense clusters of what look like identical plants, but if you look closely you will see that some have a forked, Y-shaped stem whereas most have just a single stem (below). Only the Y-shaped stems produce a flower then later the apple-like fruit. Mayapples are actually misnamed, as in May they still only have the white flower, which is found in the base of the fork. The hanging ‘apple’ doesn’t appear until later in the summer, and despite the name, is not pleasant to eat and may even be poisonous so we do not recommend that you try it.

Delaware is blessed with a kaleidoscope of beautiful native wildflowers in our area and below are a few of my favorites (from top, Virginia Bluebell, Cardinal Flower, Great Lobelia, Butterfly Weed).

These beautiful wildflowers are available at a reasonable price at the Native Plant Sale so if you want to able to observe these natural wonders in your own back yard just come on by. As well as their visual appeal they are popular with beneficial pollinator insects like bees and butterflies, so now you can have an idyllic native garden and help nature at the same time!

The Plant Sale is held at Coverdale Farm Preserve (543 Way Rd, Greenville, Delaware) Thursday May 3rdand Friday May 4th from 3pm to 7pm (member days) and Saturday May 5th (10am – 4pm) and Sunday May 6th (11am – 3pm) (open to public). Free admission if you just want to come and browse! Credit cards, checks and cash accepted. Click on the link below for more details.

Fall not only brings the oncoming burst of changing colors, but also marks the beginning of the monarch butterfly’s incredible migration to Mexico. The DuPont Environmental Education Center highlighted the butterfly’s unique journey at their 4th Annual Marsh & Monarch Celebration on September 23rd. Blue skies and sunshine greeted over 200 people who came out to celebrate the tagging and releasing of 8 monarchs. Leading up to the event, DEEC staff and visitors watched and waited as the reared butterflies transformed from caterpillar to chrysalis and finally to beautiful monarchs ready for release.

When the highly anticipated release date came, eager groups of visitors gathered on the boardwalk with a DEEC staff member to learn about monarchs and their important relationship to the milkweed plant. Adult monarch butterflies lay their eggs on the plant and the caterpillars then eat the milkweed as their sole food source. If you want to attract more monarchs to your garden, planting milkweed is a great way to do just that!

Each butterfly was then tagged with a special tracking sticker for research being done at the University of Kansas. Tagging helps monitor monarch migration patterns and the overall health of the population. Finally, the moment came that we had all been waiting for…A few lucky kids became wide-eyed as a butterfly was placed on their outstretched finger and took a few steps while deciding whether it was ready to take flight. Each time a butterfly took off the crowd clapped and cheered with enthusiasm as the magnitude of the 2,000-mile journey sunk in.

Visitors also spent the day enjoying free, interactive activities throughout the marsh. Adults and kids alike enjoyed an on-the-water experience canoeing the pond, learning basic paddling skills, and attempting to navigate the water without getting stuck in the plants.

Many chose to get their feet wet while dip-netting for aquatic animals such as dragonfly larvae, scuds, and small fish. Dip-netting is not only a fun way to explore the pond, but is also a great tool to use when measuring water quality. By studying the biodiversity of the pond, staff members at DEEC can better understand the condition of the water. Guest staff from Stroud Water Research Center echoed that sentiment by providing visitors with a chance to conduct their own water quality tests. Participants turned scientists, learned how to test for pH levels, temperature, turbidity, nitrates, and conductivity with hands on experiments like the one shown below.

Inside the nature center many other activities were underway such as “Zuumba like an Animal,” on the 4th floor. If you happened to saunter upstairs you were met with a group of kids hopping around the room like frogs or belting out animal sounds at the top of their lungs.  The 3rd floor stayed jam-packed all day with arts and crafts tables, a bike & kayak raffle sponsored by the Alliance for Watershed Education, and interpreters sharing all things marsh. The “Snapper Lab” on the 1st floor displayed many live animals that call the refuge home such as a black ratsnake, snapping turtle, and green frog. On the way out visitors stopped by to chat with Delaware Nature Society’s Habitat Stewards and left carrying armfuls of free milkweed to plant in their own gardens for the next generation of monarchs. Thank you to all who came out to celebrate and see you next year!

The days are getting warmer, and all around us, Signs of Spring abound.   The first wildflowers of Spring are popping through the leaf litter layer, while amphibians like Wood Frogs are emerging from their Winter lair to make their way to wetlands for breeding purposes.

You are invited to take part in the Sixth Annual Signs of Spring Challenge through the Delaware Nature Society.  Each week for the next nine weeks, you encouraged to get outside and look for signs of plants emerging and animals arriving.  The species we selected as classic Signs of Spring are found widely throughout most of Delaware and southeastern Pennsylvania.

The challenge is to find all 20 of these plants and animals, and make a note about the date that you find them.  Many are already out there and ready to be seen in this first full week of March, while others (like Barn Swallows and Trout Lily) are likely still weeks away from appearing.

Here is the link to open the Signs of Spring Challenge spreadsheet : Signs of Spring Challenge 2016

Enjoy exploring the outdoors this Spring, and please come out to one of our Delaware Nature Society-managed properties to explore and search for Signs of Spring with us!

The Christina River has been one of my favorite Delaware canoeing and kayaking destinations for many years. Cruising with the tide on a late summer day is about as relaxing as it can get.  However, if you are like me, the best part of the experience is searching for wildlife such as American Beaver, Great Blue Herons or basking Northern Red-bellied Cooters and soaring Ospreys.  In the last several years, thanks to my friend Hal White (no relation) I have become very interested in dragonflies and the Christina River is a great place to see several of our common species. Scanning the spatterdock and cattails and other shoreline vegetation can result in observing colorful species such as Green Darner, Twelve-spotted Skimmer, Spangled Skimmer and Blue Dasher. However, my favorite species that makes the Christina its home is the Russet-tipped Clubtail.

This large species of dragonfly is only found on tidal freshwater rivers and is not particularity common elsewhere in Delaware. Hal White, in his book Natural History of Delmarva Dragonflies and Damselflies, wrote that this species was not recorded in Delaware until 2003 when a University of Delaware student collected it on the Christina River for his required insect collection. Why the species was not recorded earlier is a bit of a mystery but Hal speculates that large tidal rivers are not a place that most skilled dragonfly enthusiasts think of checking for uncommon species.  Since the 2003 lucky find, Hal has confirmed that the Russet-tipped Clubtail is actually fairly common on the river from August through mid-October.  However, although I had been up and down the Christina River many times over the years, I had never noticed this what I now consider, a rather conspicuous insect. That is, until 2008 when Hal and I mounted a mini-expedition by canoe to photograph this handsome dragonfly for his upcoming book.   It did not take long after putting-in, that we observed several Russet-tipped Clubtails patrolling low over the water.  But photographing flying dragonflies from a shaky canoe is a bit of a challenge to say the least.  Lucky for me though, one of them perched on an overhanging branch just long enough for me to get a few photos – mission accomplished.  So if you have a chance to get out along the Christina River keep your eyes peeled for Russet-tipped Clubtails.
