Who wouldn’t want to smell a beautiful looking flower I know I would. Most allergies are not always caused by the showiest flowers. Large brightly colored flowers tend to attract bees that pollinate them. Their pollen is usually also too heavy to be carried by the wind which is very good for people with allergies.
Most allergies are normally characterized by itchy eyes, running nose, and a lot of irritation. Most flowers or plants that are hybrids tend to contain less pollen and less the chances of them causing allergies.
Here are some of the garden flowers are plants that would trigger you if you have pollen allergies.
Aster( Asteraceae)

This family of flowers is considered allergen heavy plants. During the warmer season, they can be found everywhere and anywhere and we often have them in our homes in flower vases. Although they are not wind-pollinated, they often cause allergies for those sensitive to pollen.
Baby’s breath ( Gypsophila)

They are very common in florist bouquets and although they are small, they have a lot of pollen.
Dahlia (D. × pinnata)

They are part of the aster family and are large enough to attract insects to pollinate them. Due to their large size, they have a lot of pollen and can cause an outbreak of hay fever during the warm seasons. The hybrid ‘formal doubles’ virtually have no pollen.
Daisy (Leucanthemum )

They look pristine and who would not want to go close to a daisy flower and get their sweet smell? If you have allergies, you need to be very careful because they are high in pollen although they are not transferred by the wind.
Gerber Daisies (Gerbera jamesonii)
They are the flashiest of the asher family of flowers but their pollen can set off a bout of sneezing and sniffles. Be careful before you get them into your house.

Chamomile (Matricaria recutita, Chamaemelum nobile)

The flowers are used to make beverages such as chamomile tea, however, the smell can be really strong to people with allergies.
Chrysanthemums (Chystanthemum spp.)

They are popular as indoor container flowers but don’t have a huge range of colors and sizes.
Sunflowers (Helianthus annuus)

With their big size, sunflowers have a lot of pollen which means if anyone with allergies goes close to them they will definitely react. Because sunflowers don’t have a fragrance, we tend to overlook them as a source of allergies. There are certain varieties that are hypoallergenic like ‘Apricot Twist’ and ‘Joker’ because their pollen is too heavy to be airborne. This is not among the worst flowers for people with allergies
Trees

Trees are either male or female and for pollination happen, they depend on the wind which is often the easiest way to disburse it. The main trees that rigger allergies are cypress, ash, aspen, beech, birch, cedar, cottonwood, Elm, Hickory, Mountain cedar, Mountain Elder, Mulbery, Oak, Peakan Willow
