Each gene has a special job to do. The DNA in a gene spells out specific instructionsâmuch like in a cookbook recipe â for making proteins (say: PRO-teens) in the cell. Proteins are the building blocks for everything in your body. Bones and teeth, hair and earlobes, muscles and blood, are all made up of proteins.
Hostas are quite effective among other companion shade perennials and shrubs including astilbe, dicentra (bleeding heart), ferns, tiarella (foam flower), tradescantia (spiderwort) and hydrangea. Shade Loving vs Shade Tolerant. Hosta are shade tolerant and not shade loving as many of us had thought.
Fragrant hostas are more tolerant of heat and humidity: Fragrant varieties are often the most heat tolerant and can do well in the southern USA up to growing zone 8 and sometimes even zone 9 because the H. plantaginea species hosta originated the second furthest south of all of the species hosta plants.
