| Flowering plants in central Arabia include examples of the convolvulus, mustard, pea, daisy, caper, iris, and milkweed families. |
| To one side the River Seven meandered, thick with willow, purple with balsam and white with convolvulus. |
| Every wall is green with moss and gay with masses of convolvulus and nasturtium. |
| But grey helichrysum looks good with blue convolvulus as long as you are prepared to trim back the helichrysum from time to time. |
| Upon these banks the first coltsfoot flowers in March, the first convolvulus in summer, and almost the last hawkweed in autumn. |
| The principal genera are convolvulus, Ipoma and their allies. |
