These guys will bloom with the right level of care and maturity. They need to be 30 years old before they reach the right age to bloom. Then... they will only bloom at night! It will be worth the wait though.
Cacti are very strong in eliminating bacteria, tackling pollution and reducing radiation. In addition, cacti are one of the few pants that continue to absorb carbon dioxide at night and release oxygen. Putting a cactus in your bedroom is said to be helpful to aid sleeping and supplementing oxygen.
