Which common garden flower is characterized by a bright yellow central disk surrounded by white ray petals?
Daisy
Chrysanthemum
Marigold
Sunflower
The daisy (Bellis perennis) has a distinct yellow central disk with an outer ring of white ray petals. Sunflowers have larger heads and yellow rays, while marigolds and chrysanthemums display more layered or colored petals rather than a simple white-and-yellow pattern.
Which flower typically has layered petals forming a tight spiral and thorny stems?
Peony
Tulip
Rose
Hibiscus
Roses (Rosa spp.) are known for their layered, spiraled petals and thorny stems. Tulips have a simpler cup shape without thorns, hibiscus have large single petals, and peonies lack the thorny stems characteristic of roses.
Which spring bulb has a single cup-shaped flower with smooth, lanceolate leaves?
Crocus
Tulip
Hyacinth
Daffodil
Tulips produce a single cup-shaped bloom atop a smooth stem and feature lance-shaped leaves. Daffodils have a central trumpet, crocuses are smaller with grasslike leaves, and hyacinths have clustered bell-like flowers.
Which tall garden flower has a large inflorescence composed of many small florets and rough leaves?
Sunflower
Hydrangea
Zinnia
Snapdragon
Sunflowers (Helianthus annuus) form a composite head made up of numerous small disk and ray florets and have rough, hairy leaves. Hydrangeas have clusters of larger individual blooms, while zinnias and snapdragons have different leaf textures and inflorescence structures.
Which flower is recognized by six tepals and prominent stamens and a distinctive fragrant scent?
Iris
Magnolia
Lily
Orchid
Lilies (Lilium spp.) have six identical petal-like tepals and conspicuous stamens, often releasing a strong fragrance. Irises have falls and standards, orchids are zygomorphic with specialized lips, and magnolias are woody trees with larger tepals.
Which feature best differentiates a peony (Paeonia) from a rose (Rosa) in garden identification?
Presence of a prominent, visible cluster of stamens at the bloom center
Prickles along the stem
Leaves arranged in alternately pinnate fashion
Intense fragrance compared to other flowers
Peonies display a clear cluster of yellow stamens at the center of the bloom, while roses typically hide their stamens among multiple layers of petals. Both can be fragrant, and only roses have prickles on the stem, but the most reliable visual difference is the exposed stamens in peonies.
In botanical terminology, what is the collective term for all the petals of a flower?
Androecium
Corolla
Calyx
Gynoecium
The corolla is the term for the collective petals of a flower. The calyx refers to all sepals, the androecium to all stamens, and the gynoecium to all carpels.
Hosta plants are most commonly identified by which leaf characteristic?
Needle-like leaves
Variegated colored foliage
Compound leaves
Serrated margins
Hostas are known for their broad, often variegated leaves that display contrasting colors or patterns. They do not have needle-like or compound leaves, and their margins are usually smooth.
Snapdragon (Antirrhinum majus) flowers exhibit which type of symmetry?
Bilateral symmetry
Whorled symmetry
Asymmetrical
Radial symmetry
Snapdragons have zygomorphic, or bilateral, symmetry, meaning they can be divided evenly along only one plane. Radial symmetry allows multiple planes of division, which is not the case here.
What leaf arrangement is typical of Zinnia elegans in garden cultivation?
Opposite leaves
Basal rosette
Compound leaves
Alternate leaves
Zinnia elegans bears leaves in opposite pairs along the stem. Alternate leaves and compound leaves are not characteristic of this species, nor does it form a basal rosette.
Which garden flower thrives in acidic soil and partial shade conditions?
Lavender
Sunflower
Marigold
Azalea
Azaleas prefer acidic, well-drained soils and benefit from partial shade. Marigolds and sunflowers prefer full sun and neutral soils, while lavender thrives in alkaline, well-drained conditions.
Which plant is well-suited to shady, moist woodland garden habitats?
Dahlia
Hosta
Petunia
Geranium
Hostas thrive in shady, moist environments typical of woodland gardens. Petunias, dahlias, and geraniums generally prefer sunnier, drier conditions.
What term describes small spots or markings on flower petals?
Actinomorphy
Apomixis
Maculation
Punctation
Maculation refers to spotting or speckling on petals. Punctation is a term for tiny pits, apomixis is a reproductive process, and actinomorphy describes radial symmetry.
How can you differentiate Calendula officinalis (pot marigold) from Tagetes patula (French marigold) based on petal shape?
French marigold petals are tubular and fused at the base
French marigold has broad, smooth petals
Pot marigold has smooth, entire petal margins
Pot marigold has deeply serrated petal margins
Calendula officinalis typically has smooth, entire petal margins, while Tagetes patula often displays serrated or lobed edges on its ray florets. French marigold petals are not tubular and fused; that trait belongs to other genera.
What is the botanical term for the stalk that attaches a leaf blade to the stem?
Stipule
Petiole
Raceme
Peduncle
The petiole is the stalk that connects the leaf blade to the stem. A peduncle is a flower stalk, stipules are leaf appendages at the base, and a raceme is a type of inflorescence.
A garden flower with plicate (folded) corolla lobes forming a bell-shaped (campanulate) bloom most likely belongs to which genus?
Dianthus
Campanula
Cosmos
Lupinus
Campanula species are characterized by their bell-shaped, campanulate corollas with plicate lobes. Lupines have pea-like flowers, cosmos have daisy-like heads, and dianthus has fringed petals.
In horticultural classification of dahlias, collarette types are distinguished by which floral feature?
Needle-like tubular petals forming a spike
A single outer ring of petals with an inner collar of smaller petals and exposed disc florets
A fully double flower with no visible disc
Only a single row of petals without any collar
Collarette dahlias have one outer row of larger ray florets and an inner collar of shorter petals, leaving the central disc visible. Fully double types are classified differently, and single or tubular forms match other categories.
Nicotiana alata differs from other ornamental tobacco species by what key floral trait?
Night-scented tubular flowers with reflexed corolla lobes
Blue-colored blooms produced year-round
Large flat star-shaped flowers
Compound pinnate leaves
Nicotiana alata produces long tubular flowers that open in the evening and emit a strong fragrance, with corolla lobes that reflex backward. Other ornamental tobaccos lack this nighttime scent and reflexed form.
Canna indica, commonly used in water garden plantings, shows optimal growth in which habitat condition?
Alpine rock gardens at high altitude
Sandy desert conditions
Dry, rocky soils with full shade
Marshy, tropical wetlands with full sun
Canna indica thrives in warm, wet habitats such as marshy tropical wetlands and performs best in full sun. It is not suited to arid, alpine, or heavily shaded dry environments.
Lavandula angustifolia (English lavender) exhibits which leaf adaptations for Mediterranean climates?
Narrow, linear leaves with dense hairs and oil glands
Broad glossy leaves with drip tips
Fern-like compound leaves
Needle-like leaves and waxy succulence
English lavender has narrow, linear leaves covered in fine hairs and oil glands to reduce water loss in dry, Mediterranean climates. It does not develop broad drip-tipped, needle-like succulent, or compound leaf forms.
