Biomass is fuel that is developed from organic materials, a renewable and sustainable source of energy used to create electricity or other forms of power. Some examples of materials that make up biomass fuels are: 1  scrap lumber; 2  forest debris; 3  certain crops;
At most, some flowers linger into part of the following day. A large cereus cactus may have several blooms, but the plant's entire bloom season may last only two days. Some genera bloom in spring or summer, while others flower in early fall.
Extend the bloom season by deadheading, as Razzle Dazzle dwarf crape myrtles bloom from flowers on branch ends. Removing the flowers and pods encourages new buds for a second flowering in late summer and early autumn. Deadhead by snipping off dead or faded flower clusters at any time during the summer.
