Annualscomplete their lifespan hertz ( sprouting , flowering , setting germ ) in one growing season and do not grow back . The condition is used both for plant that have a short life cycle and do not stomach suspend temperature . Petunias and old maid are vulgar annuals .

Perennialshave a multi - yr life cycle and , if suit to ourhardiness zona , will go hibernating in the wintertime and summarize development in springiness — year after class .

Biennialstake two long time to finish their sprightliness cycle ( from germination to germ production ) . biyearly vegetables like carrot can be harvested in twelvemonth one for food for thought or depart over wintertime for a second yr if unfolding and seed production is desire .

Once you know the basic distinctions , it ’s good to twofold - check the plant shred orseed packetfor specific details or do a little extra research .

For example , some plants sold as annuals are in reality long - dwell and can be kept beyond our growing time of year with a little spare tending while others are short - live on .

Plus , the same species , like lavender , can have annual and perennial diverseness . It ’s easy to buy the wrong type if you ’re not checking the plant tag carefully .

Differences Between Annuals and Perennials

Bloom Times

Flowering annuals tend to have sporty , more vibrant heyday ( a common trait in warmer and tropic clime ) that last an total growing time of year — but that ’s it . That same plant wo n’t regrow next year .

efflorescence perennial are often subtler in colour and form and bloom for shorter period — sometimes just days or weeks . While less showy , the do return to bloom again year after twelvemonth .

Costs

In the short - terminal figure , annuals tend to be lower in price than perennials , presumptively because they are quicker - growing ( utilise few greenhouse resources ) , sell more by volume , and can be intemperately discount by retailer as time run out .

perennial tend to be dear upfront but , with their multi - yr lifespan and ability to spread , are more economical overall . And less waste scores more environmental points .
