Rocky Plains Dwarf Morning Glory

Rocky Plains Dwarf Morning Glory is a key stone plant.
On Little Cayman, it is the sole host plant for the endemic diminutive land snail on Little Cayman. It is also found on central Grand Cayman among pockets of decomposed leaf.
This medium airy mound will produce a profusion of small white flowers along erect branches that falls over resembling a bridal bouquet of ‘Baby’s Breath’ with its delicate white flowers.

Horticulture potential:
This elegant small bush has stiff branches that will create an 18-inch mound in height and width; this delicate little Dwarf Morning Glory will delight your pathways with a daily profusion of new inflorescences.
Its herbaceous growth habit lends itself to be a perfect garden edging plant material whether you are situated on the beach or you have a rich soil garden. It will thrive in a full sun to mostly sunny exposition and it will survive with minimal care or enjoy your pampering.
