|1. What kinds of jasmine have fragrance and white or pink flowers?
2. What other plants have strong fragrance and flowers?
|Lots of plants are fragrant. Here's a short list:
Evening stock (M. longipetala) Small lilac colored blossoms with powerful lily-like perfume; excellent for window boxes and pots.
Nicotiana - flowering tobaccos (Nicotiana alata, sylvestris, suaveolens) Plants with tubular white flowers, fragrant mostly at night.
Four-o'clock (Mirabilis jalapa and M. longiflora) Multicolored trumpet flowers cover bushy 2-foot-high plants. M. longiflora has white flowers with orange-blossom scent.
Heliotrope (Heliotropium arborescens) Large violet or white flowerheads with a vanilla/cherry pie scent.
Mignonette (Reseda odorata) Powerful vanilla/raspberry fragrance from small yellowish flowers; attracts beneficial insects; direct sow in early spring.
Night phlox (Zaluzianskya ovata ) Unusual snowflake flowers are strongly fragrant at night.
Peruvian daffodil (Hymenocallis species) Especially 'Sulfur Queen'; white or yellow spidery summer-blooming bulb; 18 inches high; perennial in zones 8-10.
Petunia (Petunia) Many modern varieties have little fragrance, but old-fashioned white or purple vining types release a strong lily-like fragrance at dusk.
Stock (Matthiola incana) Spicy clove-scented flower spikes; excellent cut flowers; thrives in cool weather.
Sweet alyssum (Lobularia maritima) Low-growing groundcover with honey-scented white flowers; highly attractive to beneficial insects.
As for fragrant jasmines, this is very subjective -- what I find to be the most fragrant jasmine plant may not be the same one you would choose. I can give you suggestions, but ultimately you need to smell the jasmine plants for themselves and decide which has the most appealing fragrance.
Here are a few that many people enjoy:
Cestrum nocturnum, Jasminum sambac 'Belle of India', J. sambac 'Grand Duke of Tuscany', J. azoricum, J. grandiflorum, J. fluminense.
Best wishes with your fragrant garden!
