Some Plants and Their Pollinators
Flowers Pollinated by Beetles
Flowers are dull-colored or white, have sour or fruity odors, and have heavily protected ovules. A couple of examples include:
- Calycanthus species (Sweet shrubs)
- Paeonia species (Peonies)
Flowers Pollinated by Bees
Typically conspicuous and usually bright blue or yellow, never completely red. They frequently have "honey guides"-special patterns or markings that guide the visiting bees to the nectar within. Examples include:
- Acer negundo (Box elder)
- Achillea millefolium (Yarrow)
- Aesculus pavia (Red buckeye)
- Caltha palustris (Marsh marigold)
- Coccoloba uvifera (Seagrape)
- Cornus florida (Flowering dogwood)
- Erica tetralix (Cross-leaved heath)
- Eschscholzia californica (California poppy)
- Geraea canescens (Desert sunflower)
- Geum rivale (Water avens)
- Guaiacum sanctum (Lignum vitae)
- Hamamelis virginiana (Witchhazel)
- Oenothera biennis (Common evening primrose)
- Penstemon palmeri (Palmer's penstemon)
- Phlox adsurgens (Phlox)
- Phlox paniculata (Fall phlox)
- Phlox subulata (Moss-pink)
- Piscidia piscipula (Jamaica dogwood)
- Pithecellobium guadalupense (Blackbead)
- Potentilla fruticosa (Shrubby five-fingers)
- Quercus virginiana (Live oak)
- Ribes odoratum (Buffalo currant)
- Ribes sanguineum (Red-flowering currant)
- Solidago species (Goldenrods)
Flowers Pollinated by Butterflies and Moths
Similar to bee flowers, mainly because both groups are guided to flowers by a combination of sight and smell. Some species of butterflies, however, are able to perceive red as a distinct color, and the flowers they favor are red and orange. The nectary of a moth or butterfly flower is often located at the base of a long, slender corolla tube or a spur and is usually accessible only to the long sucking mouthparts of these insects. Examples include:
- Aloysia gratissima (Bee bush)
- Apocynum androsaemifolium (Spreading dogbane)
- Asclepias subulata (Desert milkweed)
- Asclepias tuberosa (Butterfly weed)
- Bebbia juncea (Chuckwalla's delight)
- Calliandra eriophylla (Fairy duster)
- Ceanothus americanus (New Jersey tea)
- Celtis pallida (Desert hackberry)
- Clethra alnifolia (Sweet pepperbush)
- Dalea frutescens (Indigo bush)
- Dalea greggii (Indigo bush)
- Echinacea purpurea (Purple coneflower)
- Eriogonum fasciculatum (Coastal buckwheat)
- Glandularia gooddingii (Verbena)
- Hyptis emoryi (Desert lavender)
- Lotus scoparius (Deerweed)
- Lycium andersonii (Wolfberry)
- Mimulus species (Monkey flowers)
- Monarda fistulosa (Wild bergamot)
- Prosopis velutina (Velvet mesquite)
- Pycnanthemum muticum (Mountain mint)
- Senna covesii (Desert senna)
- Solidago species (Goldenrods)
- Thymophylla pentachaeta var. pentachaeta (dyssodia)
Flowers Pollinated by Hummingbirds
Typically contain large quantities of thin nectar rich in carbohydrates. Because hummingbirds have a poor sense of smell but an excellent sense of sight, the flowers they visit have little odor and are red or yellow. Examples include:
- Anisacanthus thurberi (Desert honeysuckle)
- Aquilegia formosa (Red columbine)
- Astragalus coccineus (Scarlet locoweed)
- Calliandra eriophylla (Fairyduster)
- Castilleja angustifolia (Desert paintbrush)
- Castilleja sessiliflora (Downy paintbrush)
- Chilopsis linearis (Desert willow)
- Cynoglossum grande (Hound's tongue)
- Delphinium cardinale (Cardinal larkspur)
- Delphinium nudicaule (Orange larkspur)
- Dicentra chrysantha (Golden eardrops)
- Erysimum capitatum (Western wallflower)
- Fouquieria splendens (Ocotillo)
- Justicia californica (Chuparosa)
- Kalmia latifolia (Mountain laurel)
- Lonicera sempervirens (Trumpet honeysuckle)
- Mertensia virginica (Eastern bluebells)
- Mimulus aurantiacus (Orange bush monkey flower)
- Penstemon eatonii (Eaton's beardtongue)
- Penstemon palmeri (Palmer's penstemon)
- Penstemon pseudospectabilis (Arizona penstemon)
- Phacelia campanularia (Desert bell)
- Sphaeralcea ambigua (Apricot mallow)
- Stanleya pinnata (Prince's plum)
Flowers Pollinated by Bats
Large, sturdy, dull-colored, and "fruity" scented, and contain large amounts of nectar. Bat pollination occurs mostly in tropical areas. Examples include:
- Adansonia digitata (Baobab)
- Carnegiea gigantea (Saguaro)
- Kigelia pinnata (Sausage tree)
- Lemaireocereus species (Organ-pipe cacti)
Flowers Pollinated by Wind
Usually have exposed stamens (which hold the pollen-bearing anthers) and correspondingly small, reduced, or entirely absent sepals and petals, and they are produced before the leaves. The stamens typically hold large amounts of pollen. The following list includes families of plants that are entirely or predominantly wind pollinated:
- Betulaceae (Alders, Birches, Filberts, Hazelnuts)
- Cyperaceae (Sedges)
- Fagaceae (Beeches, Oaks)
- Juglandaceae (Hickories, Walnuts)
- Juncaceae (Rushes)
- Poaceae (Grasses)
- Ulmaceae (Elms)
- Urticaceae (Nettles)
Flowers Pollinated by Water
Flowers of water-pollinated plants tend to be rather small and inconspicuous. This type of pollination is thought to be an advanced feature among angiosperms.
- Callitriche hamulata (Water starwort)
- Ceratophyllum species (Hornwort)
- Halophila species (Sea grass)
- Najas species (Naiad)
