Gardeners' Notes:

Positive ChrisZ5 On Oct 25, 2011, ChrisZ5 from Tracy, IA (Zone 5a) wrote:

This is the first year I have planted these, and I love them. Did not do much until late June here in Zone 5, when the foliage finally took off. By mid July started to have a few blooms, then they really went to town. We have had one freeze so far and these plants did not seem to mind and are still blooming heavily.

Positive straea On Jun 20, 2008, straea from Somerville, MA (Zone 6b) wrote:

One person's "spindly" is another's "trailing". I like the trailing nature of these plants and in the past have grown them well in pots, where they can wander around under bushier, more robust plants and hang off the edge with their pretty blooms. This year is the first year in many when I've tried them in the ground. So far they are producing lots of foliage but nary a bloom, but I think they may not be getting enough sun in their current position. Maybe more people should try growing them in pots.

Positive bluespiral On Jan 25, 2007, bluespiral from (Zone 7a) wrote:

I have found that with skimpy, floppy plants like this one, that they become very beautiful and lush interplanted with curly parsley - very pretty in pots and as an edging. They seem to enjoy each other's company very much. The white convolvulus tricolor with yellow toward the throat is particularly well set off by the fresh, crisp green of the parsley.

This plant wintersowed nicely. A beautiful flower. I think next year I will plant them more densely or intermixed with a few other plants. Makes an excellent planter specimen.

Positive SeattleSun On Aug 15, 2005, SeattleSun from Seattle, WA wrote:

I plant this along my walkway every year and it's stunning. does get a little leggy and spindly but I stagger the seed plantings and cut back the vines after they get too long and go to seed. I save the seeds every year (hundreds and easy to harvest) to reseed in the spring.

The first year i grew this plant it didn't do well for me i had it in the shade.
But I moved them to full sun and they were Great the next year.
They go Great with all my M.G.'S.
I like to plant them at the feet of some of my vines.

These cheerful little flowers open in the morning and stay bright all day. Very easy to grow from seed.

Positive carolann On Oct 4, 2003, carolann from Auburn, NH wrote:

These grow vibrantly as long as you do not plant them where Morning Glories or Sweet Peas grew the previous year - the soil needs to be replenished since both of the mentioned plants sap the soil of all of its nutrients - thus resulting in poor growing for whatever is planted the next year. Try fortifying your soil with egg shells and Miracle Grow, even some mulching, between plantings.

Beautiful blossoms, but spindly, leggy plants, not at all "mound-like" like some descriptions read. Not worth the planting.

I grew this for the first time this yr. and it was a disaster!!! I put it in a spot where I had morning glories last yr. so I thought they'd grow good there-WRONG!!! the colors were faded-looking nothing like the pics show them.they grew spindly and flopped over, turned black. I finally pulled them all up. dont know if their poor show was due to the heavy rains but I probably wont be growing this again.

Neutral Ladyfern On Aug 7, 2003, Ladyfern from Jeffersonville, IN (Zone 6a) wrote:

The flowers are darling, but the plants themselves are spindly and floppy. They need to grow in with other plants like sweet alyssum that will fill in for them. Started blooming in July here in zone 6.

Neutral Chrysalid On May 27, 2003, Chrysalid wrote:

Use poor, sandy, well-drained soil in full sand. Withstands salt as well as drought, but cannot tolerate wet soil.

Neutral lupinelover On Jan 25, 2003, lupinelover from Grove City, OH (Zone 6a) wrote:

A wonderful plant for full sun; sadly, it does not withstand any foot traffic. Be sure to put it safely out of stepping reach of workmen.

Neutral Cine On Aug 6, 2001, Cine from Lufkin, TX wrote:

Bush flowering, drought-tolerant, morning glory-like flowers. Distinctive, gold throated trumpet flowers of clear, bright blue with white centers. Bloom freely in beds/containers from early summer until frost. Ideal for hanging baskets or as spreading, ground cover.

Sow seed in ordinary garden soil in a sunny area in spring after danger of frost. Sow seeds 2-3 inches apart and cover with 1" of fine soil. Firm lightly and keep moist. Seedlings emerge in 7-21 days depending on soil and weather conditions.

Thin seedling to stand 12-18" apart when plants are 1-2" high.

Garden Hint: For earlier bloom, seeds may be started indoors about 6 weeks before outdoor planting time.

Neutral jody On Nov 28, 2000, jody from MD &, VA (Zone 7b) wrote:

Best cultivated in sun in any moist well draining soil. One of the most popular cultivars in this species is 'Blue Ensign'.
