Gardeners' Notes:

Positive DavidLMo On Sep 3, 2014, DavidLMo from St Joseph, MO wrote:

Lovely gentian blue plant which may be over wintered indoors. Tends to be a short lived pimpernel which is usually grown as an annual out of zone.

A beautiful annual to short-lived perennial in my climate with stunning royal blue flowers. It is fairly easy to grow from seeds.

An excellent little plant - continued to crank out blooms all summer (with no deadheading), backed by beautiful, neat foliage that does not decline. Flower color is a most surprising deep bright blue. Low-growing, very wide spreader (2+ feet). Excellent edger plant for the front of the border. It does not transplant well at all though - I had best results with direct seeding. Withstands frost very well. I had blooms from early July into October from a mid-April seeding.

My plants look straggly and brownish, probably because I didn't tip pinch it in the beginning, but the intense blue flowers are gorgeous.

Also known as Blue Anagallis.

Positive BamaBelle On Aug 8, 2006, BamaBelle from Headland, AL (Zone 8a) wrote:

Flowers are vivid blue with pink and yellow centers. Blooms open on sunny days and close as rain approaches, hence the name. Can spread to 16". Pinch tips in spring and early summer to encourage plant to spread.
