Marigolds are a pop selection for garden and landscapes due to their vibrant colors and ability to disgust pests . When it comes to determine whether orotund marigolds are perennial , it ’s important to realize the different case of marigolds and their ontogenesis habit .
First , countenance ’s talk about the dissimilar types of marigolds . There are three main specie of marigolds ordinarily develop : Tagetes erecta ( African marigold ) , Tagetes patula ( Gallic marigolds ) , and Tagetes tenuifolia ( signet marigolds ) . Each species has its own characteristics and growth use .
African marigold ( Tagetes erecta ) are the largest of the marigold species , with tall stems and magnanimous , showy flowers . They are typically grown as annual in most regions , intend they fill out their life story cycle in one growing time of year . However , in warmer climate or under friendly conditions , African marigolds may ego - seed and come back twelvemonth after year , giving the appearance of being a perennial .
French marigold ( Tagetes patula ) are modest in size compare to African marigolds , but they provide a wide kitchen range of colouring material and flower forms . Gallic marigolds are also by and large farm as annuals , but like African marigold , they may self - seed and issue in subsequent years if conditions are favorable .
Signet marigolds ( Tagetes tenuifolia ) are the little of the marigold mintage , with frail leafage and lowly , treat flowers . They are often grown as annuals and are not typically known to be recurrent . However , they may also self - seed and amount back in the following year if conditions are suitable .
It ’s worth noting that marigolds are known for their ability to create abundant seeds , which can result to self - seeding and the visual aspect of perennial emergence . If you allow your marigold plants to go to seed , you may get novel seedling pop up in the same area the following year . This can give the imprint of marigolds being perennial , even though they are technically reproducing from seminal fluid .
In my personal experience , I have grown marigold in my garden for several years . While I mainly grow them as annuals , I have observed some self - seeding and the restoration of marigold flora in subsequent twelvemonth . However , the ego - seeding is not consistent , and some years I have had to replant marigolds to maintain their presence in my garden .
To summarize , although big marigolds are typically produce as annuals , some variety show may self - cum and appear to be repeated . However , their repeated - like increment is due to the come germinating and newfangled plants emerging , rather than the original plants occur back year after year . Therefore , it is more accurate to moot marigold as annual with potential for self - seeding and occasional “ recurrent - like ” doings .
