Yes, dahlias are perennial flowers, meaning they come back year after year from the same plant.
Producing flowers costs the plant in terms of diverting resources. If, for example, the insects which are likely to pollinate the flowers are not around at that time of the year, the production of flowers would be an expensive but pointless activity.
The plant is classed as a biannual (flowering in the second year).
A plant that lives for two years and flowers in its second year is called a biennial. Biennials typically focus on vegetative growth during their first year and then produce flowers and seeds in their second year before completing their life cycle. Common examples of biennials include foxglove and parsley.
Flowers produce seeds for the plant
Pollen from flowers on one plant can fertilize flowers on a different plant. What is this process called?'
Digitalis or foxglove is a biennial (it grows one year and flowers the next then dies)
It is not up to the plants when to or not to produce flowers. It depends on how healthy the plant is after fertilisation. The healthier the plant is, the faster it will produce flowers.
no! it is neither a flowering plant nor a fruiting plant
yes it does have flowers. Pipal tree does bear flowers
A plant that lives for two years and flowers in the second year is called a biennial. Biennials typically germinate in the first year, grow leaves, and store energy, then flower and produce seeds in the second year before dying. Examples of biennials include parsley and foxglove.
The time you plant flowers depends on the type of flowers you are planting. An almanac can help you determine the best times to plant anything.
