Plant all types of hardy lily seeds this month. Check lily references to find whether varieties are normal or retarded germinators. Plant those that germinate in a short period of time in pots or flats. Slow types should be put into jars of moistened peat moss or vermiculite and set in a cool, dark place.

When they form a small bulb and roots, transplant them to a flat in a warm. sunny place. Amaryllis should be in growth now, and if you hanker to experiment, try pollinating two of your favorites. Seed develop in record time, and should be planted immediately about one-fourth inch deep in loose, rich loam.

If they are not crowded, and are kept in good growth, they may bloom in from 18 to 24 months after sowing of the seed. Begonia seed of all types may be planted this month. Semperflorens and tuberous rooted varieties started now will bloom this year.

Rex, rhizomatous and cane types planted now will give show for next fall and winter. Plant gloxinia tubers now for bloom during April and May.

Seeds planted this month will give blooms for this summer. Just for fun, dig up a clump or two of pansies, violas, or violets from the garden. Pot them and set in a cool, very sunny place. Their cheerful flowers will be out in no time!

Keep azaleas cool (60 degrees) and syringe the leaves with room temperature water to increase humidity. Daffodils, tulips and other spring bulbs should be brought to sunlight and a warm window sill (60-75 degrees) now for forcing.

Plant kalanchoe seeds for bloom next Christmas. February is a good month for starting leaf cuttings of your favorite African violets. Cut the leaf stems to about an inch in length and set them to the base of the leaf in a moist mixture of coarse vermiculite and peat moss.

Check the lists of seedsmen for new plants and spring flower pots to try in your window garden and/or greenhouse. The gesneriad family to which African violets and gloxinias belong, also offers the following spring flower plants meritous of a place in every collection: aeschynanthus (trichoisporum), achimenes, episcias, hypocyrta, rechsteinerias (sold as Gesneria cardinalis), columneas, smithianthas, streptocarpus and kohlerias are among the worthwhile members of the gesneriad family.

Other plants to try are the hoffmannia, the miniature Caladium Humboldtii (C. argyrites), Vitis Voineritma, Pedaltmthus tithymaloides, Clerodendrum Thomsoniae and on and on the list would grow! Try something new this year.
