Many gardeners consider most Convolvulus plants to be weeds. Though many species, such as Silverbush and Dwarf Morning Glory are grown as garden plants.
The aforementioned plants are short-lived perennial evergreens they are not very hardy, so are often grown as annuals.
They make great container plants and indoor plants, and also perform well in rock gardens, sunny beds and borders, or Gravel Patios.
The annual varieties of Convolvulus bloom from mid spring, or summer to autumn, whereas perennials flower in the summer.
If you have a problem with spreading and need to remove Bindweed from the garden, then simply cut them down to the base. Keep doing this until new growth no longer occurs (because the plant is starved of energy).

If planning to grow Convolvulus plants outside from seed then they should be planted at a depth of 3 mm (1/8th inch).
Sow into a sunny part of the garden in the middle of spring.
If growing Silverbush or other Convolvulus plants indoors, then start about two months before putting out.
Next, the seed should first be chipped with a knife and soaked in warm water for a full day beforehand.
They should be sown into peat pots in an area with a temperature of 22 to 28 degrees centigrade (71°F to 82°F).
Germination takes about one to two weeks.
Convolvulus Care: The seedlings of small Convolvulus species should be transplanted outdoors after the last frost of spring.
If you require more plants then cuttings of Convolvulus these can be took in the summer.
Convolvulus Care: As an evergreen shrub it is best to prune in middle to late spring or once flowering has completed (depending on the time the specific species bloom. Simply remove any dead or diseased tissue.
Pruning heavily can also help to rejuvenate neglected plants.
