MID-ATLANTIC GROUP

The 20th annual edition of the Seed Exchange Catalog includes 901

seed donations contributed by 59 gardeners, from begin-ners to professionals. Ninety- seven new plants were donat-

ed for the first time. As you can see, this seed program in-cludes new plants not previ-ously offered, as well as old favorites.

We’re sure you’ll enjoy perusing this year’s selec-

tions and you will find plants your garden can’t do with-out! Since some listed seed is in short supply, you are en-couraged to place your order early.

How to Use this Catalog

Each list entry is identified by a combina-tion of a six-character Plant Code and a Donor Code. The list is organized alpha-numerically by plant code. We have listed each plant and the basic facts about it only once in the following format:

Plant Code Botanical name. COM-MON NAME. Plant type. Light requirements. Plant height × spread. Bloom season.

After the plant name and basic plant facts, you’ll find any further information from each individual who donated that particu-lar plant as follows:

Donor Code - Flower color. Donor’s description of or comments about the plant. Germ: Donor’s germination information, if provided. Donor name.

‘Cultivar name’ of plant from which seed was collected is identified, if avail-able, within the Botanical name. Please keep in mind that seedlings from cultivars may not come “true” from seed. They are not genetically identical to the parent. The seedlings they produce may look identical to the seed parent, may resemble the seed parent closely, or they may look very dif-ferent from the seed parent.

Germination Codes, Methods

PretreatmentCMS Cold moist stratify. Sow in pot and place outside in January or February, or stratify by placing in the refrigerator for the required time in a sealed plastic bag containing a seeded pot, a mix of seed and some sowing mix, or a layer of seed within damp paper towels. (Seal bag well, since ethylene gas from fruit can affect seed germination.)Frz Freeze the seed for the period noted.NST No special treatment.Scfy Scarify seed before sowing. Scarify means to penetrate the seed coat to al-low water absorption, which thus speeds germination. This can be accomplished by abrasion, nicking, chipping, filing, thresh-ing, soaking, dousing with boiling water, or other such means.WMS Warm moist stratify. Same as for CMS, but at room temperature.

Light RequirementsBC Barely cover seeds.D Requires darkness for germination. Cover with lid or aluminum foil to ex-clude light.L Do not cover seeds; light is needed for germination.SS Surface sow.

TemperatureBH Bottom heat, used for any seed requir-ing soil temperature more than 70°F.C Cool, approximately 50° to 60°F.R Refrigerate after sowing.OW Overwinter outdoors.W Room temperature, approximately 65° to 70°F.

Germination TimeMaximum time is listed in days (d), weeks (wk), months (mo), or years (yr).

Special NotesCycle Seeds require alternating periods of cold and warm to germinate.Rtp Resists or resents transplanting.SIS Sow in situ (directly in the garden).SR Store seed (dry) in refrigerator before sowing. Note: this differs from CMS, which requires moisture.

Seed Starting Pointers by Gene Spurgeon

The following article, entitled Late Spring Seed Exchange Notes, first appeared in the May 2007 HPS/MAG Newsletter. It is reproduced here to encourage your participation in this year’s exchange and to get you started as soon as you receive your package of seed in early February. The earlier you begin, the bigger your plants will be when you set them out in warmer weather.

In 2007, after the Seed Exchange had concluded for the year, two 3-hour hands-on workshops at the Henry Foundation addressed a variety of seed-starting techniques. Session leaders Lorraine Wallace and Rob Broekhuis are HPS/MAG members who have had success and much enjoyment growing new plants from seed; their own gardens attest to their prowess.

Lorraine and Rob noted that some techniques work better for certain seeds, but not others. When selecting an approach, consider your priorities. If time is not an issue and you want to maximize your success, get a set of Norm Deno’s Seed Germination Theory and Practice manuals or references that we list with the seed mailings. These techniques have been tested and the success rate measured; they will expose you to a wide variety of procedures. If you received 25 packets of HPS/MAG seed, you could end up with 25 different approaches.

If time is an issue, try a few simpler approaches; Lorraine and Rob suggest less time-consuming methods. Learn to accept some failures—there is always next year for a different approach. And, a technique that might appear to fail may work out after all. One friend ordered her first seeds from the Exchange, planted them, and two weeks later when we spoke was disappointed that she hadn’t yet seen any seedlings; but some seed takes months, even years, of several temperature cycles to germinate. If several months elapse and there is no sign of life, check a reference to confirm that you are on

the right track. If time to complete germination is the issue, hang in there. If light, temperature, or moisture is the issue, make some adjustments or try again next year.

To accelerate production of new plants, it is generally necessary to start early indoors, about two months before the last frost for annuals and the easier perennials. For woodies and some perennials, starting could begin in the fall. One approach is the frequently termed “Deno or baggie method” that supports germination in a compact manner without rigid containers. It starts with a ziplock type plastic bag, usually a sandwich, snack, or smaller size. The baggie’s portability and clear sealed walls can support an ideal microclimate with a controlled amount of moisture, light, or warmth. Place the seed in the bag with a medium such as peat moss, vermiculite, or a peat/perlite germination mix. A paper product, such as a moistened folded paper towel or coffee filter, is also acceptable. Each type medium has its proponents; experiment to see which works best for you. Avoid using paper with really fine seed, since the hair-size roots become enmeshed in the paper fibers and are tough to extract.

The clear plastic allows easy inspection to determine germination progress. When the seeds have their first root (radicle), transplant to cellpacks or small pots for growing under vertically adjustable fluorescent lights. $10.00 shop lights with two $2.00 cool white tubes work fine; don’t waste a bundle on special growlights with a scientifically approved color-corrected spectrum.

When the new plants have outgrown the cellpacks, move them to larger pots. By that time, they probably will be ready to move outdoors to benches or into the ground. Make sure they have adequate light and moisture supplemented by a weak solution of liquid fertilizer. The time when young plants go into the ground depends on

size and need to nurse them along to the point that they can survive the rigors of natural conditions.

Planting the seed directly into a pot is another approach to indoor starting. It takes more space but has the advantage of not requiring the transfer of delicate germinated seed to other containers. This approach commonly begins with a 4" pot filled approximately ¾ full with moistened peat/perlite mix and topped with approximately ¾" milled sphagnum moss (not peat). While the moss does have natural mold inhibitors, it can be moistened with a weak solution of hydrogen peroxide to further restrict mold growth and resultant damping-off seed death. Once the seed is planted, the pot is sealed in a gallon size food storage bag with a wire twist fastener. This should be the cheapest thinnest store brand, since the porosity will allow some air exchange but will retain moisture. The whole is then placed in conditions appropriate for germination, in most cases, under fluorescent lights. For plants requiring darkness to germinate, the pots can usually be moved to light when the first cotyledon leaves appear. Once the first true leaves have emerged, a crowded crop can be separated and moved to other pots.

Another easy method is what Rob identified as wintersowing. A growing body of gardeners advocates this and, of course, they have web sites. Check out: http://forums2.gardenweb.com/forums/wtrsow/ or http://wintersown.org/. Wintersowing involves sowing the seed in a seed mix in the fall or early winter in pots or flats that are covered with plastic wrap for moisture retention and punctured for adding periodic supplemental moisture. They are then placed outdoors in the garden, in a coldframe or even an unheated garage. Depending on location, you might need to provide some wire mesh screening protection against critters. If not under a roof, the location should be shaded from the sun.


Advantages include decreasing the sowing effort and eliminating the space required to house pots, lights, etc. Following a natural cycle in the life of a seed, the process is also relatively carefree during this period of semi-dormancy. The disadvantages are that growing conditions are less controlled and growth doesn’t start until warmer weather returns, therefore, separating and repotting seedlings must be done during the busy gardening season. For the Mid-Atlantic area, the technique is most appropriate for plants native to temperate zones. Lorraine has found it especially useful for spring blooming plants like Hellebores, which require a period of warm moist stratification (the summer), then a period of cold moist stratification (the winter), followed by a final period of warm moist conditions (the spring).

Both Lorraine and Rob recommend using a ¼" layer of finely crushed granite called granite grit on top of the soil mix for all wintersowing. For sowing fine seed, place a layer of grit on top of lightly tamped soil mix, then scatter the seed on top of the grit. Most will fall between the granules, but

spray a light mist of water over the grit to be sure the seeds reach the mix. For medium size seed, scatter seed directly on the tamped soil mix and add the ¼" or larger grit layer directly over the seed. For really large seed, push gently into the soil mix until level with the top, then add a grit layer.

The weight of the grit helps hold the soil mix and seed in place until roots provide sufficient anchorage. It offers both protection from slugs and reduction in growth of lichens and moss that can be detrimental to young seedlings. While Rob uses grit primarily for only wintersowing outdoors, some seed starters recommend wider use for a variety of reasons. Because the grit changes from dark when moist to a lighter color when dry, it’s a good visual indication of the moistness of the soil mix and the need for watering. Space between the granules also promotes better health by allowing dappled light to reach the seed and encouraging good air circulation.

While some garden centers carry granite grit, a more reliable source is an agricultural supply store that sells

grit to poultry growers. Poultry grit can contain oyster shells; use only granite grit, since it is inert and does not alter the pH. An alternative is washed coarse builders sand, however, the chance of contaminants is greater than with crushed granite. For plants that require aggressive drainage in their soil mix, grit is an alternative to adding shredded bark, perlite, or vermiculite. The drawback is greater weight, but longevity is an advantage.

The methods summarized here cover just a few of the possibilities. To explore these in more detail or to follow up on other techniques suggested in the workshops, pull out the book and web site reference list on page 2 of this document. Then visit the web or your local horticultural library to find what best fits your level of commitment. Better still, attend a seed propagation workshop with HPS/MAG or any local horticultural organization. The hands-on give-and-take of a workshop instills confidence and builds camaraderie and contacts with the larger very knowledgeable propagation community.
