There is also a trueAmaryllisgenus, containing just two species native to South Africa.
The blooms are typically a deep red, pink, white, or blend of these colors.
you’ve got the option to expect your amaryllis to bloom for seven weeks or longer.

Amaryllis has components in the bulbs, leaves, and stems that are toxic to people and pets.
The bulbs should be planted 10 to 12 weeks before you want them to bloom.
Place a bamboo stake alongside the bulb.

Keep the soil moist but not wet.
A thick flower stalk should shoot up within a few weeks after planting.
The flat leaves will follow as the flower stalk matures.

If you’re doing that, simply follow the setup steps used for spring planting.
After your amaryllis has bloomed, cut back the flower stalk but allow the foliage to continue growing.
you could place your plant outdoors in summer in partial shade if you like.
Water your amaryllis whenever the top two inches of soil becomes dry.
Feed it with a half-strength,water-soluble fertilizerevery two to three weeks.
Stop feeding in August, and bring the plant indoors.
At this point, it’s time to expose your amaryllis to dark conditions.
The lack of foliage and water will induce the amaryllis to send out another flower stalk.
Resume watering at this time, and move the plant to a warm, sunny indoor spot.
Leaves will appear, and blooms will soon follow.
After flowering, withhold feeding for eight to ten weeks to induce the dormancy needed to reset the bulbs.
Caring for Amaryllis Outdoors
InUSDA hardiness zones8 to 10, amaryllis can be grown outdoors.
It will grow infull sun to part shade conditions, but partial shade is the best environment outdoors.
If your area is entirely frost-free, plant the bulbs with their necks at or slightly above ground level.
Water thoroughly after planting, but then water only when the top two inches of soil is dry.
After leaves appear, feed with a balanced fertilizer once per month through blooming.
When flowering is complete, remove the flower stalks but keep the foliage to continue growing.
If any leaves turn yellow, cut them off.
In fall, apply a layer of winter mulch if your area experiences winter frost.
The plants typically go dormant over winter.
Keep watering the plant until it goes dormant in the fall.
Propagating Amaryllis
Amaryllis bulbs will produce small side bulbs similar to the waydaffodilsmultiply.
Overwintering
Amaryllis plants located in USDA hardiness zones 8 to 10 can be left as-is for winter.
But in zone 7, they can be overwintered in the garden by applying a heavy layer of mulch.
Outdoor plants might be feasted upon by slugs and snails.
Amaryllis also can be infected with what is known as red blotch and mosaic virus.
Unfortunately, there is nothing you might do about either of these diseases.
Move the plant to a dark, cool, dry spot, and cut off the depreciated foliage.
Leaves will start to grow soon, followed by flowers.
Amaryllis bulbs can live up to 25 years.
And during that time, they will multiply, producing offshootsalso known as bulbilsand creating additional plants.
Overwatering or underwatering are two of the biggest issues when growing amaryllis.
An amaryllis can have up to three stalks sprout up from the bulb, depending on variety.
Each stalk will produce anywhere from two to six flowers.
