I have a small collection of sansevierias, also known as mother-in-law, good-luck plant, bowstring hemp, and Devil’s tongue. Year in and year out I enjoy them for their handsome foliage, but I am writing about them today because one of my more unusual plants is in bloom, Sansevieria cylindrica. Elephant’s toothpick and spear sansevieria are two of the common names I found for this plant.

The flowers are creamy white, lightly fragrant, and open as the central stalk of the inflorescence lengthens. (Descriptions of this plant I found in reference books and on-line say the flowers are pinkish, but I don’t see that in my plant.) In my experience, sansevierias bloom on their own schedule, so I have learned to appreciate the flowers whenever they appear.

For those of us who care about such things, the inflorescence is a raceme. That means it is indeterminate and continues to lengthen as the flowers open. Today, the tallest flower stalk is nearly 40 inches tall, and the shorter one 25 inches. Both are still lengthening. The individual flowers are carried in little clusters up and down the main stem, with buds mixed with spent flowers. Individual flower buds are 2 inches long. When buds open, the individual petals roll back, so the flowers are slightly shorter in bloom.

Sansevierias in general couldn’t be easier to care for. Give them well-drained soil and let it dry out between waterings. Fertilize sparingly. Give the plants bright light in winter (my S. cylindrica is next to a south-facing window) and partial shade in summer. All my sansevierias are outdoors from spring to fall  in a spot that receives morning sun and afternoon shade. They do spread by rhizomes, but are pretty content to remain in the same pot for years. I saw pictures of S. cylindrica on the internet with leaves that were braided. As you can see by my picture, I manage my plant with a spiral of copper pipe to keep the leaves from spreading too widely.

S. cylindrica is reported to be a good air purifier. (Plants Rescue has more information on this along with extensive cultural information.) According to Portland Nursery, the species also has been grown for centuries “because they are believed to share the same eight virtues as Taoist deities, the Eight Immortals.” Whatever benefits sansevierias bring to the home garden—great foliage, good luck, air purification, or surprise flowers—they make welcome additions to my indoor garden.

For most of this year I have been AWOL from Eastern Shore Gardener. I have a good excuse, though. In March, I adopted a puppy from Mid-Atlantic Border Collie Rescue. Puppy raising and training pretty much engulfed my year after he came home with me. I also raised a litter of rescued puppies for MABCR, but that is another story!

This year’s focus on bringing up a well-rounded puppy has simply engulfed my ability to sit down and write about my garden. Having a puppy outside with me all the time also affected what I can do in the garden, since puppies want to put everything in their mouths and dig holes whenever they get a chance. So, this year supervision took precedence over actual gardening.

Gryff is just over a year old now, and well on his way to being a great family member. He is learning manners, has started in agility, and is a much better garden citizen. He also is currently learning to be a tracking dog and may one day be experienced enough to find lost dogs and cats through an organization called Dogs Finding Dogs.

I have made some progress out there this year, including planting a variety of ground covers and new perennials. I also installed a wall where we had piled stones until a couple of weeks ago and am looking forward to getting it filled to overflowing. I promise you will see pictures next season.

As always, my garden is speeding along this spring, and I am just barely keeping up. Today’s post features a couple of plants that have been especially spectacular this spring. I don’t take much credit for the display. All do their thing without any intervention from me.

For the past couple of weeks, the front garden is all about our native wild blue phlox (Phlox divaricata). I started with a handful of small plants that rode down with us years ago from Pennsylvania. These easy and accommodating wildflowers self sow, and I brought down plants in a range of colors in shades of lavender and lilac-blue to white. This spring, the front garden is filled with great clumps in a full range of shades. There also are some deep purples elsewhere in the garden that I am encouraging to sow around. I simply can’t stop looking at them, plus wild blue phlox has a delightful light fragrance as long as the weather is not too windy.

Wild blue phlox thrives in partial shade to partial sun, and tolerates evenly moist to somewhat dry soil. The seedlings appear in surprising spots and are always welcome!

Whether I have been writing e-mails or delivering a gardening talk, one of my favorite hollies inevitably comes up once the conversation turns to plants that should be more available: American holly (Ilex opaca) ‘Maryland Dwarf’. Any of you who have tried to buy  ‘Maryland Dwarf’ will know that it is difficult, if not impossible, to find.

So, I am happy to let readers of Eastern Shore Gardener know that Vic Priapi, owner of Priapi Gardens, has ‘Maryland Dwarf’ in his nursery this spring. His first plants all sold, but he is picking up ten more 3-gallon plants today (Friday, April 8). I suspect there are plenty of gardeners looking for ‘Maryland Dwarf’, so if you want one, don’t dawdle. (If you are driving from a distance, it is probably a good idea to call and check availability first!)

Ilex-'Maryland-Dwarf'-with-

Above: ‘Maryland Dwarf’ holly (Ilex opaca ‘Maryland Dwarf’) at Mt. Cuba.

Unlike standard-size hollies, this is a true shrubby ground cover. Plants range from 3 to 5 feet tall and spread to 6 or 8 feet. My own plants are considerably shorter—all are under 3 feet. They have handsome, glossy, evergreen leaves. Plants produce very few berries. I have two plants in shade and one in fairly full sun. ‘Maryland Dwarf’ makes a handsome ground cover for shade, a specimen in the shade garden, a companion for low-growing perennials or ground covers that won’t swamp it, or a component of a shrub border.

So, I hope that those of you out there who have been wanting to try this great plant will swing by Priapi’s in Cecilton!

Now Vic, how about some dwarf white pines?

Welcome: The news is full of information on supporting pollinators, and mason bees are sone of our most effective and efficient native pollinators. This great post on mason bees is by Paula Shrewsbury from the University of Maryland’s Department of Entomology. I first saw it in The University of Maryland Cooperative Extension publication, Landscape and Nursery IPM Report, and I knew it would be of interest to a great many Eastern Shore Gardeners. Enjoy!

Since some pollinator species are in decline it is important to conserve these beneficial insects. Therefore, I will be discussing various pollinators throughout the season. The solitary bees to discuss this week are mason bees which are in the family Megachilidae since mason bees began to emerge from nesting habitat at my house just over a week ago (Columbia, MD on March 16th). In general, mason bees are early spring pollinators but a few species emerge in late spring or early summer. Mason bees nest in hollow stems of plants, reeds or galleries in wood left behind by wood boring insects. Mason bees get their name because of their habit of making compartments in their galleries that are separated by mud.

Mason bees are well known for the pollination benefits they provide and are some of the earliest pollinators of the season. It is estimated that just 250-300 mason bees can pollinate an acre of apples or cherries. Mason bee males emerge first and females emerge a few days later. This phenomenon, called protandry, is relatively common in the world of insects. It seems that female mason bees are a highly sought after “commodity” and males that emerge early in a season are more likely to find and hook up with mates. Once a male and female mate, the male bee then hangs out on the female’s back and fights off other males that would also like to mate with his partner. This “guarding behavior” ensures sperm from the original male are used by the female.

Mated female mason bees spend many hours and days gathering pollen and nectar from which they create pollen cakes or balls. They fill hollow plant stems or wooden galleries with these pollen cakes. After collecting pollen from plants, the female returns to her nest and enters the nest tube head first, deposits the pollen cake (this may take several trips to get enough pollen for one cake), exits the tube, turns around and enters the tube abdomen first. She then oviposits (lays) an egg onto the pollen cake. She then seals that section of the tube or gallery with mud. The female repeats this process until the tube contains several pollen cake – egg compartments and is filled. She plugs the entrance with mud and may then search out another nesting site. Eggs that are destined to be females are laid in the back of the tube, and male eggs toward the front.

Mason bees are active about 4 weeks and the females will fill as many nests (tubes) as she can in that time. The eggs hatch into bee larvae that consume the cake as they develop and grow during summer and fall. They complete their development (pupa and adults) during fall, settle down for winter, and are ready to emerge just in time for the return of spring. Mason bees do not produce honey, are not aggressive and do not sting. I stand for long periods of time in the midst of the 100’s of bees busy around their nesting site in my yard and have yet to be harmed but am always entertained by these beauties.

Mason bees provide valuable ecosystem services by pollinating a variety of native and non-native flowering plants, many of which are fruits that we consume or flowers of plants in natural and managed landscapes that provide resources and habitat for animals at other trophic levels. For those of you who would like to become active in the conservation of mason bees you have a little bit of time still – but hurry! At my house I have purchased commercially available “bee tubes” and drilled holes into firewood (see the images). Not only can you enhance ecosystem services of pollination, but you create a great learning environment for children and adults. I highly suggest you try buying or making habitat for these beneficial, educational and very entertaining insects. There are many resources on line that can inform you of best practices for creating habitat and raising these beneficial insects. Do a web search for mason bees or bee tubes. NOW is the time to set up nesting sites!

Winter aconites, hellebores, snowdrops, and daffodils are in full bloom, and many more perennials are pushing up out of the ground. Although it is technically still late winter, for me, spring is here already. With spring come the annual plant sales and seed swaps.

I have posted a page one such event, Community Plant and Seed Swap, which promises to be a fun exchange of plants and seeds. It is scheduled scheduled for Saturday April 23 at the Pickering Creek Audubon Center in Easton, Maryland from 10:00 a.m. to noon. (Address: 11450 Audubon Lane, Easton, MD 21601; Phone: 410-822-4903). Why not make plans to join them, and pick up some new plants for your garden?

I am always on the lookout for perennials that are able to withstand summertime heat and humidity and still look great as the growing season wanes. This year one of the late-season standouts is hosta ‘Dick Ward’. Despite the drought this summer, coupled with neglectful watering, it remains attractive well into October.

While the foliage color is certainly fading, and there are a couple of browned-out leaf edges, all-in-all ‘Dick Ward’ remains quite attractive. Earlier in the season, the leaves were bright green with darker green margins.
