if you mean "hosta" as a plant the older they are the bigger they grow.
One plant that is easy to grow are different types of hosta plants. Another easy plant to grow are day lilies.
Hostas will grow in zones 3 to zone 9. They are not a tropical plant.
Hosta that will grow in full sun are August Moon, Blue Angel, Royal Standard, Sun Power, Venus, and Albomarginata.
Hosta = Taglilie or Funkie
You can split the hostas in the fall as long as you replant them with at least one month before frost so that the hosta can grow new roots.
Most of the time, a hosta will have the same leaf markings as the parent plant. Some will be sports which means they are different than the parent plant. Most hosta is grown by tissue culture.
Hosta is used in shady areas where many flowers will not do well. The hosta flower is not very pretty but it does attract butterflies.
Bird of paradise is a tropical plant. Hosta is a plant that grows from zone 3 to zone 9.
As long as the hosta leaves were not diseased, you can compost them.
Some people do grow hosta indoors. Hopefully only the minature versions because some hostas get very large.http://houseplants.about.com/od/Plant-Profiles-April-2014/fl/Hostas-Growing-Hostas-Inside.htm
Hosta is a shade plant in the garden. However some have had great success growing them as house plants. Be very careful if you have dogs or cats because they are poisonous to pets.
