AUTUMN SOWING 
Seeds of certain rockery and border per¬ 
ennials, of many bulbs, shrubs, and trees seem 
to be benefited by a period of exposure to low 
temperature. The best way to handle such 
seeds is to sow them in open ground seed beds, 
or in cold frames, in late autumn. The seed 
bed should be lightly mulched with peat moss, 
straw or litter during the colder months, to 
keep it from drying out, and to prevent frost 
heaving. Germination of all the species listed 
in this folder will be helped by late autumn 
sowing, except, of course, the House Plants, 
which should be sown indoors. 
Beside the kinds listed here, autumn sow¬ 
ing will be found beneficial to the following, 
offered in my General Catalog: Scottish Hea¬ 
ther, Maianthmum, Epimedium, Violets, Meco- 
nopsis, Monotropa, Arum, Crawfurdia, Podo¬ 
phyllum, Cyclamen, Leucojum, Alstroemeria, 
Convallaria, Polygonatum, Jeffersonia, Smila- 
cina, Asarum, Uvularia, Funkia, Cortusa, Dis- 
porum, Incarvillea, Baptisia, Cassia, Geran¬ 
ium, Clintonia, Cotoneaster, Mespilus, Ho- 
venia, Blueberry, Clematis and the like. Please 
understand that the kinds listed above, and 
in this folder, are not necessarily sown in 
autumn. It is simply that there is some gain 
in quicker and easier germination when this 
is done. 
WINTER SOWING 
Sowing may be done just as long as the 
ground can be worked. In the North this 
usually means November or December, but in 
regions with open winters, sowings may also 
be made in January and February, or even 
in early March. Wherever you may live, 
should the ground freeze before you can sow, 
you may simulate actual ground sowing with 
much the same benefit by stratifying alternate 
layers of seeds and damp sand or peat moss. 
This should be done in an unheated shed, the 
pile covered with litter to prevent drying, and 
all left until early spring, when the treated 
seeds may be sown outside for quick germin¬ 
ation. 
TRUE WILD FLOWER BLEND 
I have blended the seeds of more than one 
hundred kinds of Wild Flowers for this mix¬ 
ture. They are chiefly American sorts, but 
there are a few from temperate climates of 
Asia and Europe. Most of them are naturally 
perennial, but enough are annuals to make a 
good showing first year. Included are Sabbat- 
tia, Gentians, Violets, Arbutus, Golden Aster, 
Solidago, Quaker Ladies, Belamcanda, Yucca, 
Meadow Beauty, Pentstemon, Mertensia, Ver- 
nonia, Jack-in-the-Pulpit, Wintergreen, Wind¬ 
flower and many more.. Sow it in quantity 
for neighborhood and countryside beauty. V*
