Late Summer Mt. Cuba Center Visit

I was at the Mt. Cuba Center last weekend for a little late summer photo stroll. Here are a few of the sights I saw.

The round garden perhaps off from the main house is a dazzling array of color now, though perhaps a little busy for some. While it's comprised of mostly nonnative annuals, it serves as a bustling stop for an assortment of butterflies who's host plants are all around some ~650 acres of fairly well kept wilderness and native plant gardens. 

I'm not sure what the purple plant is but it's foliage contrasts well with the brightness of the Lantana in bloom among other flowering plants. Here some skippers flutter about. Among them were an assortment of Swallowtails, Monarchs, and Fritillary Butterflies that proved too quick for me to photograph. 

Elsewhere in a native flower bed the Swallowtails were a bit more cooperative. Here two Tigers sip at an Ironweed, I believe the cultivar is Vernonia angustifolia 'Plum Peachy' which is like 'Iron Butterfly' but about twice as tall. 

Praying Mantises were abound in the meadow garden. Not only were females laying eggs but also in the act of mating... some with more than one partner courting them at the same time. 

Though the woodland was filled with an assortment of Woodland Asters, I found the Richweed, Collinsonia canadensis, to be particularly interesting.

Though common in woodland areas across the eastern United States, it's not something a lot of people stop to look at.

Part of the issues that it's not a more mainstream plant is likely due to the large leaves of the plant, compared to the fairly delicate flower stalks that come above. The flowers are small and not entirely noticeable either. I actually walked past the patch of these plants twice before I even noticed it. It's plants like this where interesting leaves or flower shapes from cultivation would benefit to get it sold and brought into the main nursery trade.

Ephemeral Plants for Honeybees

 I did a second visit to the Mt. Cuba Center this past weekend. A week prior to that was their yearly Wildflower Celebration. Most of the wildflowers hadn't opened yet or at least very few of the individual plants had flowers, but most at least had one flower open somewhere in the gardens, including Twinleaf and Trout Lily to give you an idea of how early the blooming was. Overall though there weren't enough flowers to make for a dramatic impact as I was hoping.

I'm happy to report that there were more flowers open this past Saturday, and the spring gardens will probably be at their peak this up coming weekend May 8 - 10, 2015. Any longer then that and I'd fear the Virginia Bluebells will be past their prime as well as many of the Trilliums.

It was a bright sunny day and I was on the lookout to see what the honeybees were working. 

While I'm sure they were busy nectarine on Maples and early Mints and Magnolias, there were a few of them partaking of the Virginia Bluebells.

Presumably they're mostly going after the pollen. Judging from the long tube shaped flowers I don't think the honeybees could reach the nectar all to well. Woodland Poppies were also blooming, which don't produce nectar at all and offer their pollen much more easily, so it's likely the little bit of nectar they can reach is what has them favoring this plant.

There were a few trying to find other ways into the flower to get at the richer stores inside. I didn't think to look for carpenter bee damage at the time.

Also just starting to really flower was Fernleaf Phacelia. This is easily one of the most under rated woodland plants. It's a biannual that requires cross pollination from separate plants to produce viable seed.... and yet what few nurseries bother to sell this plant, only sell it as the second year flowering form. It's a biannual! Just sell the seeds!

When you put a biannual in the ground it suddenly wants to put energy into producing its roots, instead of flowering and making seed... but there's a ticking clock that tells the plant it's time to die. This is a plant that needs to be planted at a specific time of year to stress it as little as possible. 

Most beekeepers grow Phacelia tanacetifolia, which is a western annual that has a piss poor time reseeding in our eastern soils. The benefit of growing Phacelia bipinnatifida instead would be growing a species better suited to eastern conditions and having a nectar plant that grows in full shade. 

When it does get established, it likes to spread it's seed like crazy. First year plants simply grow a rosette of leaves, and after the first winter they begin to flower and start the whole process all over again.

Jacob's Ladder was another one I noticed honeybees working but only on my prior visit. I didn't see any working it this weekend and I'm unsure why. Maybe it was the time of day?

In other bee related news I noticed several bumblebee queens swooping in amongst the leaf litter, inspecting places to start a nest. I'd have expected many species to already be past this stage. Where I am in New Jersey I'm starting to see the first workers out foraging. Perhaps this is one of the parasitic species looking to replace a queen. 

Spring Pollinators

Although it was a breezy cool day in the 60's, I managed to have some fun with my camera today. Here is a sweat bee taking refuge from the chilly air in the flower to an apple tree. They were collecting pollen but a few, (males?) that were hanging out in the flowers. Apples aren't quite at their peak here. 

Here is what I believe is a mining bee working the native plum trees. There are tons of flowers on the trees this year so I should get another bumper crop like I did two years ago. I was pulling 800+ plums off of each tree, though native plums are small and bite sized. Still though, it was quite a lot of fruit for a first year's flowering.

These types of bees like to burrow in sandy hillsides usually clear of tall foliage; often in full sun, though the early species/generations work do full shade just fine because the trees haven't filled in yet. I'm not sure how successful these shaded burrows turn out though compared to ones in full sun. But of course tall grasses and forbs may grow more abundantly on sunny locations.

Last week I saw all the queen bumblebees flying about looking for nest locations. And now I see they've all settled in it seems. Bumblebee queens that are collecting pollen are committed to starting a nest. Pollen if fed to developing brood while the nectar of the flower feeds the adults. Some nectar is turned into honey too and also fed to the brood but bumblebee honey is runny and contains high amounts of pollen anyway. 

Here I watched a queen visit the flowers to our gooseberry/currant. It was neat watching her work these small, inconspicuous flowers, when the native plum, apple, and peach trees are all right beside them. She was devoted to visiting each and every flower on this shrub, ignoring ones she already visited. I did see her fly to the plum tree once, but that was very clearly an accident on her part, as she virtually walked right over the flowers in search of the gooseberry she'd been working. Bees are often devoted to the pollen of the type of plant they work because the nutritional value can vary greatly from plant to plant. It's best to raise brood on one type of pollen to perhaps judge the results, or maybe it's detrimental to mix and match pollen types? Whatever the case, this devotion to one type of plant is what makes them excellent pollinators.

Also buzzing about were the beeflies. These do visit flowers, though the ones I saw seemed to be more interested in sunny themselves on the mulch. These mimic bumblebees to gain entry into the nest and lay their eggs in the hive. I don't believe all beeflies do this, others simply lay their eggs adjacent to the nest and the resulting maggots crawl inside, or have some other host/parasite relationship worked out with other things. I don't see them that often honestly. 

And lastly I thought it was interesting to see some actual flies doing some pollinating. This was on our peach tree, which the honeybees were also working in favor of the plum and apple. However, it was just cold enough that the honeybees weren't out in abundance for me to photograph. Flies though seem better weathered about the cold and were flying from flower to flower. This one was sipping at the nectar in the flowers it visited before turning around and darting off. To be honestly though it reminds me of a parasitic fly, so perhaps they were laying eggs or something as they visited the flowers. 

2013 Best of Bees

For bees I was thrilled to find Honeybees working Fern Leaf Phacelia this year. Beekeepers are always gushing over the Phacelia flowers for their bees but always had to rely on the western native annuals. Phacelia bipinnatifida, is an aggressive biannual that grows abundantly in woodlands, going as far as carpeting the forest floor with puffy clouds of purple flowers. This shot was at the Mt. Cuba Center and I picked up a few plants to hopefully establish in my yard but I'm not entirely confident it's going to work. Here's hoping I can get a population going.

I noticed a queen bumblebee earlier in the year. Honestly I can't remember where this image was taken or what she's even on. On a positive note though this was a stellar year for bumblebees. They were easily the most abundant pollinator in my garden this year.

Stiff Coreopsis put on a huge display. This is a slightly aggressive species which spreads by root suckers out in all directions, though they invasion is slow going. They really just push out 3 to 6 inches. They're not as floriferous as I would like them to be, other species of Coreopsis can be covered in flowers where as these seem to space it out.

Another queen out on Butterfly Weed, Asclepias tuberosa. Eventually they stop foraging all together but this year I was seeing them well into the end of June and mid July.

This is the yellow variety of Butterfly Weed. It seems to be a bigger hit with pollinators.

Honeybees go to the yellow ones more it seems. I have seen patches of orange Butterfly Weed that were covered in honeybees but none of my plants seem to have any luck.

Here another species of Bumblebee is working one of my rare plants, Asclepias rubra. This is called Red Milkweed but annoyingly enough I believe Prairie Moon Nursery has started calling Swamp Milkweed Red Milkweed. This demonstrates how unreliable common names are.

Bumblebees bustling around the Buttonbush.

Cup Plant. This is when I got my new camera. Notice how much clearer the subject is and how much more blurry the background appears.

A group of sweat bees socially foraging on Butterfly Weed.

Joe Pye Weed.

Another Oh HA! moment when my new camera became worth every penny. Now if only the darn bee were facing the camera.

Here a few bumblebees work a species that I think might have been mislabeled. It's supposed to be Northern Blazing Star but I'm not so sure anymore. It's supposed to only reach 3' but this one shot up to 5'.

And lastly I was down at the shore later in the year where stands of Seaside Goldenrod provided food for migrating Monarchs and next year's generation of queen bumblebees.

The Wildlife Gardener's Meetup (Part 3)

On the last day of the Wildlife Gardener's Forum meetup, we went to Cape May, NJ. I had never been there before but always heard good things. On the way there we came across a grape farm (vineyard?) which still had grapes growing. It was neat to see how they protect the fruit with lines of cloth. I'll have to mimic this method myself somehow.


Also before we got there, there was a group of photographers all standing in the road, cameras focused on a tidy little garden they have down there. These people were blocking the road and all anxiously awaiting for something to happen. Apparently some west coast hummingbird species had been spotted there the previous night and everyone was standing there waiting for it to show again... we stopped a moment to think if that would be worth our time but decided it was not. While leaving we asked if it had shown and it hadn't.

Cape May is the southern most point of New Jersey which also bottle necks into a peninsula, making it ideal for viewing most things that migrate at this time of year. It was a little late though so we caught the tail end of the Monarch Migration and little else.

The park was a nice wetland area with trails leading all up and down the bays and beaches there.

The least interesting parts were those overrun with the invasive Common Reed Grass, Phagmites australis. This grass can be drown as a method of control, and though it likes growing in wetlands it's very growing habit slowly generates new land. They push up so much top growth every year that it doesn't decompose until several years more, thus the ground is slowly raised. Seeds are air born, and once established they will send out runners several feet away, making them quick to colonize.

The occasional Golden Aster, Heterotheca and Chrysopsis sp. grew in places. Overall it was a rare plant but still a nice one to see.

I don't think it's Maryland Golden Aster, but certainly something in that genus, (or the other one).

Along the beach there seemed to be some sort of restoration project. There had to be a few thousand plants of Seaside Goldenrod, Solidago sempervirens, and what might be Little Blue Stem, or it's sand and salt water tolerant counterpart.

This is a fantastic goldenrod species. If I had a dune of 100% sand in my yard I'd certainly be trying to grow it! The plant is a good size, they don't seem all that aggressive, and the flowers are as nice and showy as Showy Goldenrod.

Monarch Butterflies swooped about from plant to plant. Most of them seemed to be having difficulty staying with the plant from the force of the wind though. As I mentioned earlier this was the tail end of their migration so we really only saw a few dozen. But that's a lot more than I had in my yard this year or had seen flying around.

Beautiful Plant.

They were less common inland where the soil turned more rocky than sandy, but Monarchs found them all the same.

I got to test out my new Raynox DCR-250 Super Macro Snap-On Lens with some Monarchs and in such beautiful lighting! This little snap on works with just about any camera that has a clip on lens cap, and is well worth the money.

 

A queen bumblebee. She won't start a nest until next year but in the mean time they fuel up on nectar.

This one fooled me a bit because the bee that it was mimicking were on other plants.

This is a bee mimicking flower fly. They do this to be left alone, and sometimes to sneak into bumblebee nests to lay their eggs upon the decomposing parts of the nest. I don't think they're a pest to bumblebees (though I might be wrong) but this camo also means fewer predators will mess with them.

Back at the beach there were other critters in camo. Can you see it?

This grass hopper is perfectly colored to blend in with the beach.

The sky away as we looked away from the sun.

Goldenrod as we looked toward the sun.

... we were parked over by the light house.

Walking back to the car proved to be one of the prettiest moments of the whole day. I'll have to do this again next year.
