Euphorbia x lomi 'Yellow' (Supergrandiflora Yellow) - This evergreen succulent shrub grows to 2 to 3 feet tall with gray spiny stems that sparsely hold small oblong pale green leaves at the tips. Also at the tips of the branches are the pairs of yellow flowers (bracts). The supergrandiflora series was bred in Thailand by crossing Euphorbia lophogona with Euphorbia millii and selections were made for good color and large bracts. These hybrids are correctly known as Euphobia x lomi, a hybrid epithet formed from the first two letters of the parent species, but are generally marketed as Supergrandiflora Hybrids. The cultivar 'Yellow' has much larger flower bracts (the colorful petal-like leaves that surround the true flowers) than those typically surrounding the flowers of the common red crown of thorns. These bracts are yellow with a tinge of green on the margin and can be present year-round in mild climates but are most abundant in the spring. It has low water needs and does best in the full sun or light shade. Hardy to about 28 degrees F. A great container plant, in a rock garden or trained up as a small wall covering. Tolerates seaside conditions.  This information is based on research conducted about this plant in our nursery library and from reliable online sources. We also take into consideration observations of it in our nursery of crops, as well as of plants growing in the nursery's garden and those in other gardens we have visited. We will incorporate comments received from others and welcome getting feedback from anyone who may have additional information, particularly if it includes cultural information that would aid others in growing Euphorbia x lomi 'Yellow'.
