how far north a variety may be expected to be hardy. They are equally 
adapted to growing in pots. 
Bulbs for Winter Window Gardens 
The Bulbs and Plants listed in the catalog were selected by us to grow 
and sell because of their desirable qualities in the outside garden or as pot 
plants for winter or early spring blooming indoors. 
For pot growing we especially recommend the following. The approx- 
imate time of flowering is mentioned in parenthesis. Amaryllis Family. 
Agapanthus, (Early spring). Amarcrinum, (All seasons). Requires very 
large pot. Clivia. (Mar.) Cyrtanthus, (Winter.) Haemanthus puniceus, H. 
multiflorus and H. Katherinae. (Late spring to June.) Hippeastrum or 
Amaryllis species and hybrids. (Usually Feb. to Apr. but sometimes Dec. or 
Jan.) Hymenocallis, Species No. 1 and No. 2, are Spider Lilies of delicate 
beauty that force easily in not too large pots. Nerine filifolia and N. rosea 
crispa, (Oct. to Dec.) N. fothergilli, (Oct. Nov.) N. Bowdenii, (early winter.) 
Sprekelia formosissima. Our evergreen type is one of the most satisfactory 
pot plants which blooms now and then thru the year. We always have winter 
flowers. Tulbaghia violacea. I believe I have never seen them when not 
showing flowers. All Daffodils and Narcissus but we especially recommend 
Paper White, (Nov.-Dec.) Chinese Lily, (Dec.-Jan.) Soliel d’Or, (Dec.-Jan.) 
and Poetaz Hybrids. Allium neapolitanum. Iris Family. Freesias, (Feb.) 
Sparaxis, Ixia, Tritonia, Babiana, Baby Glads (all Feb. or later.) Marica, 
(late winter.) Moraea, all species, (late winter to spring.) Lily Family. 
Colchicum, (Aug. Sept.) Roman and Grape Hyacinths.( late winter.) All 
Scillas will flower in pots but the tender S. peruviana is especially recom- 
mended. (Late winter.) All Ornithogalums. The O. arabicum will flower 
about Easter and is taking the place of Easter Lilies that are hard to get 
at present. Lilium Harrisii, (about Easter) Lachenalias, (Dec. 15 to late 
Feb.) all varieties. Veltheimia. An exceptional pot plant and flower. (Dec. 
15 to Mar.) Oxalis, all winter growing sorts. Very bright and cheerful. 
Begin to flower early and continue long. Arum Family. Callas. White and 
Colored flower well in pots. Do not pot colored Callas before Dec. 15. White 
Callas may be started much earlier, as they have been dormant all summer. 
Miscellaneous. Anemones and Ranunculus bloom well in pots. The large 
sizes are best tho some claim that #3 size will force. Billbergias are fine 
pot plants. Do not over water in winter until they start but do not allow 
to dry out either. B. nutans blooms first, about Feb. It is a gorgeous flower. 
Other varieties later. Many have rich mottled foliage. Violets. The new 
violet Royal Robe flowers well in winter in pots in a cool room. Many other 
bulbs can be flowered in pots. We have mentioned only those we could 
recommend most highly. 
Potting Directions. Be sure drainage is perfect, by placing broken 
crock over hole and over that fine gravel or coarse sand. Soil should be 
loose and rich and so pervious that water passes thru easily and does not 
become sodden. Combine sand, garden loam and humus to get a right soil 
texture. A little well-decayed manure may be added. For acid loving plants, 
peat may be used for humus. Most bulbs like a little bone-meal. 
When potted the bulb may be well watered to settle earth around and 
start the roots. But.for most bulbs, much water before roots form is a dis- 
advantage and many will rot. Best to keep only slightly moist until growth 
starts then gradually increase. Pot bulbs early to give time for full root 
development before they flower. Too much heat and moisture may rot 
dormant bulbs before they form roots. 
This seems to be the most common cause of failure with potted bulbs. 
They are given much moisture and a warm room. Most of them should have 
a cool room at least until they start. For most of them the soil should be 
watered only once to settle soil. It is best to press the soil down and water 
only slightly, adding thereafter only enough to prevent complete dryness. 
Bulbs should be allowed to take their time about starting. Sometimes we 
get an indignant letter because a bulb rotted. The bulb was perfectly good
