I have been gardening since childhood & had only come across evolvulus in recent years. Being a fan of blue flowers, I was delighted to come across it in a "big box" store & have had fantastic success with it, year after year. I like to plant it both in the ground (namely by my pond, which has a flower bed attached to the upper levels so that it spills over the sides) & in containers of all sorts. It is wonderfully easy to maintain & keep in bloom with both organic & chemical flower foods & is easy to make other plants from cuttings. A truly wonderful plant for gardeners of all levels of mastery. I've found that when growing them in natural hanging baskets (i.e. w/ coconut liners, moss, etc.)adding crushed lava rocks (used in some outdoor grills) & using it both for drainage & blended into the soil along with a nice, rich humus & natural/organic fertilizer mixed (my favorite being Espoma's Plant-Tone & esp. the newer "bloom buster" Flower-Tone) into the soil makes this plant absolutely thrive & explode in growth. If you like to grow patriotic (red, white & blue) themed flower beds/containers, mixing evolulus with bright or dark red, ivy/trailing geraniums & Alyssum ("carpet of snow" or PW's "white knight") or PW's "Supertunia" in red, & gosh, PW offers, many wonderful choices & of course there are others from various growers available to choose from. It's not easy finding "true" blue flowers that bloom all summer long, except for lobelia, (which is another favorite of mine) so having found evolvulus & enjoying spectacular results with every plant I've bought; I give three cheers for it & recommend it for everyone.
