Gardeners' Notes:

We are growing this plant in a local community garden here near Liverpool in England. It grows in sandy soil and get quite dry. We get very few frosts and they are very light so this is an evergreen perennial that flowers all year here and covers a large area of ground. It surprises me it best performs as a water plant given how it can get in its position. My only suggestion is that it tolerates the drier position because the climate is quite cool in summer. Great plant though and looks great trailing down our sandstone wall.

This plant is easily propagated by placing fresh cuttings in water and enclosing everything in a humidity bag until it is well rooted. Unless one lives in an unusually dry area, this plant succeeds without special care in a warm, sunny environment if the growing medium is not allowed to become too dry. It is easy to cultivate in a sealed bottom container. I have successfully overwintered this plant indoors without issue in a sealed bottom container and under strong lighting.

Wonderful plant with beautiful leaves and flowers, they get succulent like leaves when mature. I have grown this one indoors in my living room which is stacked with many plants and air humidity is pretty high compared to normal homes.

first few weeks or months went well but it never seemed to succeed indoors, no matter where i placed it wether it was shade or full sun it just didn't look good and always got infested with some species of aphid. it is very intolerant or pesticides, applying those will decimate this plant.

Grow this one in a jar, glass bowl or a aquarium , grow it in something that is enclosed with high air humidity. Gotu kola never seems really happy as well but at least it seems to survive. I probably will try it again sometime in the future... read more

Like Butterflygardnr said...this is probably the best food source for the larva of white peacock butterflies, although they also feed on other members of the snapdragon family and ruellia. I love these butterflies so much, and thus I love this flower. It appears in my yard primarily after the heavy rains arrive in late may and continues to grow through December. It's a very beautiful groundcover in moist areas and the little flowers remind me somewhat of baby's breath. I just let it grow...that's why it's somewhat sad when people apply weed killing herbicides on their lawns because they are killing beautiful native plants that are very helpful to butterflies and I'd take a yard covered with water hyssop any day over a yard with a perfect lawn.

This is the preferred larval food plant for the White Peacock butterfly. The plant spreads readily forming thick mats which should be thinned at least annually to keep in bounds. It requires continually moist soil (standing water). It will tolerate brackish water. The plant is frequently used in herbal medicines to improve memory. The plant can be completely immersed in water and is sometimes used in aquariums.
