Amaryllis family. Homeland - Brazil. About 75 species are widespread in nature. The genus Griffinia is represented by 21 species and includes 2 subgenus Griffinia - with blue flowers (19 species) and Hyline with white flowers (2 species). Plants bloom in spring or early summer.
Characteristic differences of this genus: There are 5 segments in the perianth, 4 of them are of the same width, one is narrower. The segments are not symmetrically located in the perianth: 4 in the upper part, 1 in the lower. Bulbs with grayish-brown scales, shaped like those of hippeastrum. Leaves are green, wide with a rounded apex, with dark spots or venation.
Griffinia hyacinthina has small bulbs. Leaves are green (with reticular veins), oblong with a rounded apex, up to 20 cm long, narrowed at the base. On a peduncle 50-60 cm long, up to 15 light blue flowers are formed. The diameter of the flower is 7.5 cm. The petals are narrow, pointed. Blooms in spring and early summer. The fruit is a capsule.

Ker Gawl.), Lycoris hyacinthina ((Ker Gawl.) Herb.), Hippeastrum dryads (Vell.) Kraenzl. The species was included in the classification in 1815.
Griffinia - care and cultivation
Temperature: griffinia is thermophilic, during the growing season it grows optimally at 25-32 ° С, in nature the temperature does not drop below 10 ° С.
Dormancy period: plants of this genus do not have a pronounced dormancy period, however, with a decrease in illumination in the autumn-winter period, a decrease in temperature to 18-20 ° C is required, while partial aging and death of leaves is allowed
Lighting: Shade from direct sunlight. Under natural conditions, griffinia grows in shaded areas of the tropical forest, under the crown of trees, the direct sun is destructive for it. Houses are suitable for her east and light north-west windows.
Watering: Quite abundant all the time - all the time it should be damp in the back of the pot, but dry well at the top. In winter, watering is somewhat reduced, allowing the earth to dry out, but not dry out!
Air humidity: griffinia loves very humid air, one spraying cannot be done here, during the heating season a humidifier or a wide pan of water will help.
Fertilizer: once every one to two weeks with a liquid fertilizer for flowering indoor plants (or for bulbs), diluted at the concentration recommended by the manufacturer. Top dressing begins as soon as the buds bloom, and ends when the leaves begin to wither.
Transfer: annually, after the end of flowering. Griffinia loves well-drained and organic soils. An example of a soil mixture: 2 parts of peat land, 1 part of humus and 1 part of sand. Griffinia are planted in small pots, about 10-12 cm in diameter, while the bulb is completely buried in the ground, but the neck of the bulb should be level with the soil or slightly higher. Good drainage to the bottom of the pot is required.
Reproduction: by daughter bulbs during transplantation, by seeds. The separated children are planted in the prepared soil mixture in separate pots. Fresh seeds are planted in the spring in wide bowls, in peat soil, sprinkled with earth, and moistened with a spray bottle. Do not allow the temperature to drop below 18 ° C. The soil should always be slightly moistened; overdrying or moisture stagnation should not be allowed. Seed germination lasts 6-8 weeks, and griffinia will bloom only at the age of 3-4 years.
