As a horticulture and landscaping expert , I have come across various type of marigolds over the year . marigold are beautiful and vivacious flowers that are commonly found in gardens across the world . While many marigold sort are annual , there are a few that are considered perennial . In this answer , I will provide a elaborate account of the perennial marigold varieties that I have personally worked with and play .
One perennial marigold variety that stick out out is the desert marigold ( Baileya multiradiata ) . Native to the southwestern United States , this marigold is be intimate for its stunning yellow bloom and silver - grey-headed foliation . I have had the pleasure of working with desert marigold in a xeriscape garden project , where their drouth allowance and resiliency made them an excellent choice . These marigolds can hold out spicy and dry conditions , making them a expectant improver to arid landscapes .
Another recurrent marigold that I have influence with is the Gallic marigold ( Tagetes patula ) . While French marigolds are typically develop as yearly , there are some varieties that can be consider perennial in sealed climates . I have see Gallic marigolds reseed themselves and come back year after year in milder regions with mild winter . Their vibrant colors and compact size make them a democratic choice for border and container .
One marigold potpourri that I get hold specially interesting is the tree marigold ( Tithonia diversifolia ) , also have a go at it as the Japanese sunflower . This marigold can be both an annual and a perennial , depending on the climate . In warmer regions , the tree marigold can grow into a large perennial bush with striking orange tree or red bloom . However , in colder climates , it is often grow as an annual due to its predisposition to hoarfrost . I have witnessed the tree marigold ’s telling height and vibrant efflorescence in tropic gardens , where it adds a spectacular touch to the landscape painting .
To summarize the perennial marigold diversity I have discussed : – Desert marigold ( Baileya multiradiata ) is a perennial marigold that thrives in hot and teetotal condition , hold it an ideal choice for arid landscapes . – French marigold ( Tagetes patula ) can sometimes be considered a perennial if it reseed itself and survives mild wintertime in certain climates . – Sir Herbert Beerbohm Tree marigold ( Tithonia diversifolia ) is a marigold that can be both an one-year and a repeated , with telling height and vibrant peak in ardent regions .
It is important to note that while these marigold variety show can be consider perennials , their length of service and power to subsist in unlike climates may vary . It is always advisable to tally the specific requirements and hardiness of each mixed bag before planting them in your garden .
