Hippeastrum Hybrid - Amaryllis

Hippeastrum hybrid

Amaryllis is one of the most brilliantly colored spring bulbs. The cultivated kinds are largely hybrids or variants and often of complex parentage.

Blooming Time: Blooming time: December-May. Amaryllis can be forced to bloom anytime of the year.

Culture: Pot Amaryllis in a pot large enough to leave an inch of soil around the bulb--a 5 to 7 inch pot is usually adequate. The best soil is composed of fibrous loam, leaf mold, and sand with a neutral or slightly alkaline reaction. The bulb should be planted so as to leave the upper third exposed above the soil line. Water Amaryllis well after potting and then water sparingly until root growth has started (lukewarm water helps). Temperatures of 60 to 70 degrees are suitable for forcing. Lower temperature of 45 to 50 degrees will delay flowering. About 8 weeks after potting Amaryllis, they should bloom. When Amaryllis is in full growth, they should be watered frequently and fed a balanced fertilizer once a month. They enjoy full sunlight during the growing season. However when coming into flower, partial shade helps to bring out their brilliant color. After Amaryllis has flowered, it should be kept growing throughout the summer. When leaves dry out, the plant should be kept in a cool, dry, and dark location until they begin to show signs of growing in late fall or winter. The plant should be left in the same pot and given a top dressing of some type of compost.

Propagation: Amaryllis is propagated by bulbs, but may be grown from seed. Expect flowers the third year from sowing.
