Dazzling blue flowers of Evolvulus glomeratus

Evolvulus glomeratus (Blue Daze, Hawaiian Blue Eyes) –

Evolvulus glomeratus (Blue Daze) in our garden, shot Jan 8, 2008This is one charming and attractive plant that has been in and out of our garden since 2004! It’s like a love and hate relationship with us. When it dies unexpectedly, it is removed and forgotten! But, absence makes hearts grow fonder – when we chance on it at the nurseries, we’ll fall in love with it again and bring it home to try another love affair!

Its dazzling blue flowers and beautifully contrasting white throats are too marvelous to resist!

Last November, Blue Daze was added to our garden again and hopefully it will stay healthy and productive forever. I’m more inclined to believe that it will be, now that I’ve done research on it! Anyway, I’ve divided them into two pots when we brought it home about 2.5 months ago and they seem to be growing very well. Fingers crossed! ;-)

Plant Profile, Culture and Propagation :

  • Botanical Name: Evolvulus glomeratus
  • Common Name: Evolvulus, Blue Daze, Hawaiian Blue Eyes (though the latter two are also names of E. glomeratus cultivars), Brazilian Dwarf Morning-Glory.
  • Family name: Convolvulaceae
  • Plant type: An evergreen herbaceous perennial, native to Brazil and Paraguay.
  • Light: Bright light or full sun; Can tolerate partial shade to shade but will result in less flowers.
  • Moisture: Performs well with regular watering and do allow soil to dry out between waterings. Over watering can kill it. It can tolerate arid and dry conditions, once established.
  • Soil: Well-drained poor sandy or loamy soil.
  • Propagation: Easily propagated from softwood stem cuttings. Just cut a sprig and stick it into moist soil. Or, if grown on the ground, its stems tend to take root where they touch the ground, so separate the rooted stems from the parent plant with the pointed tip of a spade and plant as desired. Another easy way is by dividing its root and stem mass. Evolvulus can also be propagated from seeds.
  • Features: Evolvulus glomeratus is a tropical evergreen subshrub perennial that is grown more as an annual in cold regions.Potted Evolvulus glomeratus (Blue Daze) in our garden, March 2008 It is low-growing, reaching a height of 0.75-1.5 ft tall and a sprawling mound of 2-3 ft. wide with fabulous grey-green foliage. Downy leaves are egg-shaped (0.5 x 1 in) and alternate, held on brown woody stems that are kind of rough and hairy. Beautiful real blue 5-petaled starry flowers (1 in wide) with bright white centers are borne singly at leaf axils near terminal stems. Evolvulus flowers abundantly though each flower is short-lived and lasts for only a day. And, flowers open in the morning and close in the afternoon or downcast days, similar to the Portulaca grandiflora. Grown on ground, it sprawls and on hanging baskets it cascades over.
  • Usage: Evolvulus glomeratus (Blue Daze) as a cover plant at our inner border, 24 Feb 2012Blue Daze will be most ideal as a groundcover (cover plant) or a bedding and border plant. An excellent plant in hanging baskets, containers or planter boxes, placed at balconies, window sills, or raised on a pedestal. Most suitable in rock gardens or trailing over stone walls and trellis. And, suited too for coastal or seaside gardens as it is highly tolerant of salt.
  • Care: Macro of Evolvulus glomeratus (Blue Daze) at our inner border, 24 Feb 2012Evolvulus is quite a low maintenance plant. As long as it receives sufficient bright light or sunshine, frequent watering and a small dose of fertilizer occasionally, Blue Daze will dazzle you with its prolific blooming and luscious grey-green foliage. Repeat pinching of stems is encouraged to produce a bushy shrub and abundant flowering. Plants are susceptible to root rot if waterlogged or overwatered, otherwise they are least bothered by pests and diseases!
  • For temperate zones: Hardiness – USDA Zone 8-11. In regions that get frost, blue daze is best grown as an annual or in container that can be overwinter inside. More information here that also contains comments and opinions of other gardeners.

Update: August 8, 2009
Blue Daze seems to shine better if ground-grown. Early this year, we had our potted plants transferred to the ground, as frontal groundcovers for the inner garden bed, and they just love it as seen in the images below. Some tip cuttings as well as stem cuttings were push into the soil at the same time, and in a short period they have carpeted the ground with their lovely foliage and sweet faces in dazzling blue. How wonderful!
