Gardening With Tony
UNITED STATES—Attracting pollinators is serious business for flowers that do not rely exclusively on wind for dispersion of their pollen. Many flowers attract pollinators with flashy color. Some reward their pollinators with sweet nectar. Many prefer to use fragrance. Most flowers use a combination of two or more of these tactics.
Mock orange (Philadelphusspp.) conforms to the stereotype of fragrant flowers a little bit better, with somewhat small white flowers that are incredibly fragrant. The small pale pink flowers of daphne are even less impressive and nearly hidden among their foliage, even though their fragrance can not be ignored. The sweetly fragrant flowers of Japanese honeysuckle vines are abundant, but not too colorful. Star jasmine vines likewise bloom fragrantly and abundantly, and their bright white flowers contrast better against their glossy green foliage.
Night blooming jasmine is not appealing enough for prominent placement, and is not even fragrant during the day, but will be unbelievably fragrant on warm summer nights. Just as fragrances appeal to specific pollinators, nocturnally fragrant flowers specifically appeal to insects or bats who are active at night.
Freesia, hyacinth, lily, narcissus and some types of iris are very fragrant as well as colorful now that they are blooming for early spring. It is unfortunate that their flowers do not last long, and that there are not any comparable flowers later in the year. The same annual sweet peas and stock that bloom about now can be planted again later for autumn bloom. Sweet peas are easiest to grow from seed. Stock is easiest to grow from cell packs, and since it is actually perennial, sheltered plants can survive through warm summer weather to bloom again in autumn. Annual sweet alyssum can bloom anytime while the weather is warm.
Highlight: Pink Jasmine.
As winter turns to spring, pink jasmine, Jasminum polyanthum, blooms with abundant, loose trusses of small but very fragrant star shaped flowers. The flower buds that are initially deep pink open to soft pink, and then fade almost to white. Light shade inhibits bloom and limits foliar density, but does not prevent the wiry vines from climbing to twenty feet or so. The dark green leaves are compound with five or seven leaflets. Pink jasmine is one of the few vines that can climb lattice and light trellises without tearing them apart like wisteria and so many other popular vines eventually do. Even if it escapes confinement and gets into trees or onto roofs, it does not get too far to be pruned back within bounds.
