As an instructor for a class that assists individuals to become Master Gardeners, you are charged with answering the questions and addressing the concerns of your students. A student asks about an angiosperm plant called Sweet William (Dianthus sp.) that he added to his garden last year. He is concerned because it did not flower last year, and although it is early in the spring season, he has not seen flower buds on it this year. You immediately recognize that there is nothing amiss with this angiosperm plant, and you tell your student:
1. this plant is a perennial, so it must have produced flowers very early in the season last year.
2. this plant is an annual, so it does not produce flowers.
3. this plant is a perennial, so it will only produce flowers once in its lifetime.
4.this plant is a biennial, which means it will just take longer than a season to mature enough to produce flowers.
