Beginning in early May and running daily through mid-September, from 10:00AM to 4:00PM, Brookside Gardens South Conservatory will feature live butterflies. Come witness the butterfly life cycle as tiny eggs hatch into crawling, chewing caterpillars, which then encase themselves in jewel-like chrysalides and emerge as sipping, flying adult butterflies. Learn about the best annual and tropical plants, and hardy shrubs that are used as nectar sources to attract butterflies to your own garden. To enter to win one the tote bag, send an email with “Wings” in the subject line to WashingtonGardener@rcn.com by 5:00pm on Wednesday, May 31.

Some of the entry responses may be used in future online or print articles.

Current Issue

Our Spring issue cover story is on Community Gardens. I spent the last year gathering resources for the cover story. Community gardening is so popular right now and the supply of plots is nowhere close to the demand. I’m hoping this story will inspire more local governments to install gardens and give more gardeners the basis to demand them in their own community. I’m hearing many compliments already from readers saying, “Best issue ever!” and like. Many are enjoying the feature stories including a profile of filmmaker Cintia Cabib, whose documentary “A Community of Gardeners” will make you laugh and cry and think. Also in this issue is the Edibles column, “Magical Beans” by Cindy Brown. She shares her tips on how to grow these legendary legumes here in the Mid-Atlantic and the best varieties for our area. Our Daytrip is to American University in NW, Washington, DC. Did you know they were a certified arboretum now? You’ll also find in this issue: • a plant profile feature on Dwarf Iris • a how-to article on Building a Raised Growing Bed • a short piece on planting Bare Root Roses • a round-up of our 17 Photo Contest Winners • our InsectIndex column focuses on Bugs that Attack Broccoli and related greens • a club meeting with the Gesneriad Society (African Violets and such) To subscribe, see the page 6 of this newsletter for a form to mail in or go to our web page and use our PayPal link.

May Garden To-Do List

Spotlight Special

Tickled Pink Blueberries! Pink is the new blue. The first-ever pink blueberry Vaccinium ‘Pink Lemonade’ from Briggs Nursery (www. briggsnursery.com) is one of the most exciting new plants we have seen in years and is a must-have for your garden. ‘Pink Lemonade’ provides delicious, sweet fruit rich in antioxidants, plus four seasons of color: pinkish-white flowers in spring, bright pink fruit in summer, great fall color, and dusky auburn stems in winter. Growing about 5 feet around, this showy ornamental looks great as a hedge border or stand-alone shrub with the added benefit of luscious fruit in your cereal or pies — or by the handful! This new blueberry may be pink, but it’s as rich in anti-oxidants as its blue cousins. Gardeners may choose to leave the fruit on the bush to encourage song birds and other wildlife in the garden. The fruit ripens mid- to late-season. Growing requirements demand an acidic soil pH (4.5 – 5.5), full sun, welldrained soil rich in organic matter, and adequate, even moisture. Leaves are glossy green and lanceolate, with a serrated leaf margins. Leaf surface texture is smooth, similar to that of V. ashei. Because of the inherent self-fertility problems of rabbiteye germplasm, it is recommended that another rabbiteye cultivar be planted with ‘Pink Lemonade’ to ensure good cross-pollination. Pink Lemonade (Pink Blueberry) is in limited supply (sold out to growers!), but growers are sending them out to garden centers and they will most likely be found in late summer/fall for sale at local plant retailers and also through mail order. Folks should check with their favorite garden center to see availability or on the Briggs Web site (www. briggsnursery.com) for more updated information. 2

Here is our comprehensive garden task list for gardens in the greater DC metro region for May 16-June 15. Your additions to this list are most welcome: If you started seeds last month, thin them and start the hardening off process. • Cut back spent tulip and daffodil blooms, but not the foliage! • Divide and replant crowded daffodils. • Feed your roses and new plantings with slow-release fertilizer sparingly. • Provide supports for fast-growing perennials such as delphiniums, peonies, and lilies. • Tie up clematis and other fast-growing climbing vines. • Hose off aphids, white flies, or spider mites on your roses or other perennials. • Deadhead spent blooms on your annuals and perennials to encourage re-flowering. • Water your newly planted shrubs, trees, and perennials. • Weed regularly. • Go on a local house and garden tour to see what plants are thriving in other’s area home gardens. • Pinch back mums, salvias, and other late season bloomers to encourage bushy not leggy growth. • Check pots and containers daily for water needs. • Plant dahlias, gladioli, caladiums, and cannas. • Direct sow annual flower seeds. • Thin vegetable seeds sown directly in the garden. • Move your houseplants outdoors for a summer vacation on your porch. • Put out slug traps around your vulnerable edibles and hostas. • Prune back forsythia, spirea, and other early spring blooming shrubs. • Check for black spot on your roses -- remove and discard and affected leaves in the trash, never back into your garden or in your compost -- apply a fungicide with neem oil every two weeks during the growing season. • Cut some flowers to enjoy inside -- make a small arrangement for every room. • Sow squash and melon seeds. • Plant seedlings (or direct-sow) sweet potatoes, tomatoes, peppers, and eggplants. • Fertilize azaleas and rhodos, if needed. • Divide crowded perennials and share them. • Turn your compost pile. • Start a water garden or re-new yours for the season. • Mark and photograph your bulb plantings now, while they are still visible. • Keep a sharp eye for fungal diseases and pests. • Replace cool-season annuals with heat-loving ones. • Be vigilant for mosquito breeding spots, any standing water from a bottle-cap to blocked gutters, and clean them out immediately. Ask your surrounding neighbors to do the same. Put Mosquito Dunks or Bits in any areas that accumulate water. • Plant tomatoes and peppers. To get them started off right, put cages/stakes in at same time as you plant them, so that you are not disturbing their roots later. Place a collar (cardboard tube or cat food can) around the tender plants to prevent cutworms. Put crushed eggshells first in the planting hole of tomatoes for extra calcium and mix lime in the soil you surround the plant with to prevent blossom-end rot. Fertilizes with kelp extract or fish emulsion. • Hand pick cabbage worms from cabbage and broccoli. • Have a wonderful 2010 growing season!

Fill Your Pond to the Brim with Annuals for Your Water Garden By Kathy Jentz Just as you use annual flowers to add fast color and punch to your growing beds and containers, you can use water garden annuals for your pond to provide almost instant coverage, lushness, and flowers. Now that the last danger of frost has passed (traditionally after Mother’s Day in our region), you can set about rejuvenating your pond or water garden for the season. “Greater demand means there’s a lot more exciting aquatic plant material to be found out there,” says Chris Wilson, a technical expert at Aquascape Designs, Inc., Batavia, IL. “Today’s water gardener has their pick of hundreds of aquatic and marginal plants from water lilies and lotus to papyrus, cattails, cannas, and more.” Here is a list of annual water plants to fill your pond and get the season started in style: • Water Hyacinth: This floater needs no planting. Just place it on the ponds surface and off it goes. It has a purple, scented flower and is a prolific grower in full sun. • Water Lettuce: This is another floater plant. It is also called shellflower. The plant Water Hyacinth has pale green leaves that resemble a bunch of frilled lettuce. It is a fast grower and will quickly fill in any blank pond spaces. It divides easily for sharing with other gardeners.. • Parrot’s Feather: This plant gets its name from the feathery lime-green foliage that is beautiful to look at. It is a very quick grower that is essentially a floater, but likes to have its roots anchored in the edge of other plants’ pots or between rocks along the pond edges. • Papyrus: Add vertical interest and an exotic touch to your water garden with this ancient plant. It is a bog plant so should be placed just below the surface and at the edge of your pond. Elevate it on a few bricks if necessary. Choose a dwarf variety if you only have a small pond or water garden container. • Tropical Water Lily: Unlike their hardy cousins, tropical water lilies will not survive our DC-area frosts and freezes. However, you’ll want to add one or two to your water garden every year as these wonderful bloomers comes in luscious colors and with scents that their hardy cousins can never match. Tropical water lilies bloom either by day or night. Be sure to purchase on that will bloom during the hours you are home most and can get the most enjoyment out of it. One of the best sources for water garden plants in the area is Lilypons (www.lilypons.com) in Adamstown, MD. Since 1917, Lilypons has been the source for water garden plants and supplies. Treat yourself to a visit to their beautiful 300 acres of natural ponds, woods and rolling hills, next to the Monocacy River. They host several special events each year including Children’s Day and the British Car Show, but stop by anytime to consult with their knowledgeable staff or just to take a stroll among the herons and frogs.

Don’t have a water garden?

It’s easy to set one up even with a limited planting area. All you need is full sun, a water-tight container, and, of course, water. Just take a tub or half-barrel fitted with a liner. The container should be at least 2 feet deep and 3 feet in diameter. You can bury the tub or liner in the ground or let it sit on your patio. Now fill with water and be sure to check and patch any leaks. Once your water garden is ready, add the plants. You’ll want a backbone of perennial plants such as hardy water lily, lotus, cattails, or pickerel rush. Place these hardy plants in first and let them settle in a few days. Then layer in a few of the annuals listed in the article here. If you want to add a few goldfish, add a few drops of chlorine-remover to treat the water or let the water sit for a few days to allow the chlorine gas to escape. To prevent the build-up of algae and any chance of mosquito larvae, throw in a barley ball as well as a few pieces of mosquito dunks. Finally, add your decorative elements such as a pond pump and fountain, statuary, and lights. With one weekend’s work, you’ll have an easy-maintenance water garden to enjoy for years to come. 

Joshua Nadler will discuss the strategies regarding tree “clean up” that were used by the University of Maryland at College Park, MD. He will also discuss arboricultural topics of which homeowners should be aware; including how to prepare for record snow accumulations and tree species that are particularly acceptable to heavy snow loads. Mr. Nadler enjoys promoting and discussing trees and shrubs for the ornamental landscape with emphasis on the newer selections. He became a certified arborist in 2004. The Kindred Spirit Hybrid Oak is a tree on which he holds a patent and registered trademark. As always we have plants for our door prize table and refreshments after the meeting. The public is welcome and admission is free.

Magazine Excerpt: Dwarf Iris by Kate Tyndall

As I write this, I have 44 — yes, I counted — dwarf irises blooming in my rock garden. I cannot tell you how much joy they bring to me each year when they appear, usually right around the beginning of February, and exactly when most needed. They were on schedule this year, and, even after being covered by a two-foot blanket of snow, resumed blooming unscathed once the snow melted. In fact, they seem to have appreciated the extra water the snowmelt brought. The three-to-six-inch dwarf irises, looking like so many tiny standard bearers at attention in the garden bed, are but the beginning of the iris’s march through our spring gardens, with various species holding sway at different times over the next several months. Miniature bulbs are a passion of mine, and I freely admit that, when it comes to irises, the dwarf ones are my favorites. That said, I like them all, and there is a huge variety to choose from. The tall bearded form is probably the iris most familiar to people. It was certainly the iris that I remember growing in unplanned patches in our yard when I was a child. The colors most common then were violet, purple, yellow, and white. Today, breeders have given us irises in a paintbox of colors, solids as well as bicolors. The bearded irises (Iris germanica) come by their common name because the falls — the three petals that reflex downward from the trio of stiffly upright petals known as standards — have a fuzzy strip running part-way down the middle of each petal. The beard is strictly ornamental, although it would seem to provide a cushy landing place for pollinators. If I were a bee, I’d certainly opt to glide in onto that soft landing strip, which would seem tailor-made for the purpose. The beard may be the same color as the falls or it may be a contrasting color. In bicolor irises, the beard might be different in color from either the standards or falls. Irises, of which there are some 300 species, fall into two broad categories: bulbous, like the dwarf irises such as I. reticulata, I. histrioides, and I. danfordiae; and rhizomatous, which grow from swollen underground stems, or rhizomes. The bulbous irises.... Want to learn more about Dwarf Iris, Bearded Ladies, and other Spring Delights?
