Agave attenuata Nova, sometimes called the Agave attenuata Boutin Blue, is a large rosette succulent with soft, spineless, bluish-green leaves. It grows into a large cluster of 4-5 ft (120-150 cm) tall by 8-10ft (240-300 cm) wide with individual rosettes about 4-5 ft (120-150 cm) wide. At first, the rosettes grow flush with the ground but with time, the rosettes will grow on top of short, smooth gray stems up to 5 ft (150 cm) in height.
About Agave attenuata Nova
Agave attenuata Nova differs from Agave attenuata by its much bluer and wider leaves. As with other Agave attenuatas, this variety does not have spines and so does not present any of the dangers that its spiny relatives do.
After the plant has lived its life to a decade or so, pale greenish-yellow flowers will appear in the summer on erect flower stalks that are up to 10 ft (3 m) long. This is unlike the Agave attenuata where the flower stalks droop over. As with other Agaves, the plant dies after blooming.

Agave attenuata Nova Care
All Agaves, including Agave attenuata Nova, require direct sunlight, so it is best to place the plant in the south or southeast window. In summer you can move it to the open balcony or veranda for sun exposure. If the windows of your apartment are facing north or northwest and west, the plant needs special lighting with a grow light.
Agave attenuata Nova can withstand even the most scorching sunlight, does not burn, and does not require shade like some other succulents. But if the Agave attenuata Nova was in a low-light place for a long time, then you should not immediately place it in direct sunlight. You have to get the plant used to the sunlight gradually.
All desert plants do not like excessive moisture. During the period of active growth, the plant requires moderate watering, that is, no more than 2 times in 7 days, so that the soil dries out between irrigations. Water 1-2 times a month in cold weather. It needs good drainage so that the water does not stagnate. It is important that no water remains in the center of the rosette!
The humidity of the air in the room where the Agave attenuata Nova is located must be sufficiently dry. For the summer period, take the plant outdoors for fresh air. Make sure the substrate dries completely before the next watering. There must be good drainage, and the excess water that has accumulated in the saucer must be drained.
You don’t have to place water tanks next to the plant as some plant growers do. Such a measure is necessary for other plant species, which require high humidity.
Agave attenuata Nova likes warm, dry air, so the climate of our city apartments is perfect for it. The optimum temperature is 68– 82°F. At a temperature of 64 – 68°F, the plant slows down growth and looks depressed. Spending some time at a temperature of 64°F and below can completely destroy the plant.
Agave attenuata Nova soil is undemanding, and in the wild, it grows on rocky and sandy soils. It is only important that the soil is not too dense. Good drainage and adding sand to the universal soil mix solve all problems.
The best conditions for Agave attenuata Nova are well-drained dry and sandy soils.
During the period of active growth, plant nutrition is necessary – in late spring and summer. Yes, fertilize the Agave attenuata Nova plant, combined with watering, once a month. In winter, nourishing Agave attenuata Nova is not necessary.
Agave attenuata Nova grows slowly and rarely needs repotting. If necessary, transplant young growing plants as soon as they have outgrown the container during spring. A new pot should be 1-2 inches larger in diameter. Take special care not to bury the rosette of the plant when repotting.
Also, avoid covering the stem with the substrate. Instead, cover it with pebbles for quick-drying at the roots of the stem. This is done so as not to limit the supply of oxygen.
It is very important when planting not to bury the neck of the plant, it should be slightly above the ground. Deep planting will cause the plant to rot.
Agave attenuata Nova propagates by offsets, which are formed at the base of the stem. Carefully separate them, dry a little to prevent rotting, and plant in a loose soil mixture. It is helpful to powder the cuts with cinnamon powder to promote healing. The first watering should take place three days after the appearance of the roots.
It is possible to propagate Agave attenuata Nova seeds, but it is a very long and labor-intensive process. Sow the seeds shallowly in the ground in early March. Water the soil with the sprinkler and cover with clear glass or plastic wrap. Shoots appear in about 7-8 days. The best temperature for seed germination is around 75°F.
After the appearance of shoots, remove the film or glass and after some time transplant into pots with a diameter of 2.5 inches. After a year, transplant into larger diameter containers. Soil and drainage are the same as for adult plants.
Under natural conditions, Agave attenuata Nova blooms over a period of 10 to 20 years. Then gradually thousands of small flowers appear on the stem. The plant dies after flowering because it gives all its energy to flowering and ripening seeds.
Pests and Diseases
The main plant pests are mealybugs and scale insects. After purchasing an Agave attenuata Nova from a store, check for pests. At the initial stage of infection, it suffices to wipe the leaves well, especially at the back with a solution of alcohol. Repeat the procedure within 4-5 days.
If you see that there are a lot of pests, then such insect colonies should be removed with the help of insecticides. Buy them from a specialty store and follow the instructions strictly.
If black-brown spots appear on the leaves of your Agave attenuata Nova, this indicates a fungal infection. The basic principle of the fight against the disease – special antifungal preparations containing copper.
