Convolvulus Species, Ground Morning Glory

I've had this my San Diego (inland) front yard for the past year. We're in a drought and so far it has tolerated hot, dry conditions. I...Read Moret spreads nicely, attracts bees and butterflies, and has bloomed repeatedly.

This plant has survived many challenges here in my Zone 8a garden: the worst single-year drought ever recorded combined with the greates...Read Moret number of 100°F+ high temperatures in a calendar year – without any supplemental irrigation (it went dormant); a recorded low temperature of 11°F; heavy clay soil with limestone fragments (relatively high pH).

One of my favorite plants to use in pots and in the landscape. In pots it makes a great "spiller" and when it gets plenty of water it wi...Read Morell bloom for about 8 months out of the year here in zone 9a. The roots seem to grow vigorously so I've had the most success when it is in bigger pots with regular water.

In the ground, however, this has been one of the easiest to maintain ground covers I've ever planted. It does spread and make you worry about it being invasive but in my experience growth has been easy to contain simply by occasional pruning.

This is a real gem of a plant - an evergreen, fast growing ground cover with a constant supply of flowers.

I live in a z...Read Moreone 9b area, and In the right conditions, ie full sun, well drained soil, this plant can grow five feet across or more, and flowers all summer. In warmer climates it might be invasive -- but who cares? It spreads by underground stems which pop up a foot or so from the main plant. These make good cuttings.

For five years my two plants made a spectacular display, but an unusually severe frost of -6 C killed both plants. Later on I grew a lot more and these survived every winter - I plant them everywhere. As R Weiler said, sometimes they refuse to grow and die off (?)

The flowers open sky blue and then change to a more violet blue, and the combination is superb.

A dark form is available which I must try.

Edit: one of my plants is 6 years old now, and the gravelly sandy soil suits it, because it is now 10 feet across.
