P. obtusa Singapore White #108

Not a species or a hybrid, but an open pollinated plant. Seeds from this plant have produced many different named cultivars. Large white, slight yellow eye, classic frangipani fragrance. Prolific bloomer. Very glossy, dark, rounded EVERGREEN leaves. White with small, brilliant yellow center; no pink or red bands on front or back; petal wide, round tip, no overlapping, no color bands; moderate texture; 3 1/2"; strong lemon fragrance; keeping quality poor. Large VERY fragrant lemon, bitter lemon white flowers. The leaves are dark green and glossy and are evergreen in tropical areas. White obovated flowers with yellow center and rounded tips, strong citrus fragrance, evergreen in the tropics. Unique rounded glossy leaves, compact Large 3" bright white flowers with small yellow orange center. Good citrus fragrance. Medium tree with dark shiny semi-evergreen leaves. Sweet fragrance of lemon or bitter lemon. Among the most fragrant plumeria and is easily recognized by its glossy, very rigid and dark green leaves. Evergreen in the tropics and frequently blooming while other plumeria are dormant. Difficult to root. Prone to black tip, Cold sensitive and likes dry conditions. Performs better with low water. I grafted my sing onto an unknown that seemed to not notice our big freeze 2 years ago and was the first to bloom. So while rooted cutting was black tipping, grafted is busy making an inflo. Can really take the heat and intense sun. Known more for its dark green leaves and evergreen characteristics than for its easily discolored flowers, recommended for home gardens only. Susceptible to aphids and scales, and an insecticide or light oil spray is advised to prevent sooty mold on the lower branches. White citrus-scented flowers whose waxy surface along with the bright buttery-yellow center is quite a nice contrast to the dark green and glossy leaves. Knobby ones are best. When you correct for soil moisture issues, they are as tough as the toughest ones. But they like it ***extremely porous if you are in a high rain area that gets into the 50's in the winter. Mine did fine after I put it in a mix of perlite, volcanic rock and some pine bark mulch-NOTHING else. Sings are EXTREMELY drought tolerant. Grows on dry cliffs on Greater Antilles islands. Mine does fine when I leave it out in rain and 30s until I bring it in. That is usually a couple weeks. The water goes right thru the mix out the holes. In fact, once I did that, I got seedpods and more blooms. Native to much of the Caribbean and sometimes also listed as native to parts of extreme South Florida (Monroe and Collier counties), although in general it is considered naturalized here. Like P. pudica, P. obtusa is evergreen in South Florida and looks nice all year round. The white flowers are very fragrant and trees regularly set seed. Plants are very easy to care for if kept in well draining soil, and generally do not benefit from any supplemental water here. Plumerias planted in swales or in moist areas fail to thrive and are prone to rot. Stalk green, smooth except for corky lenticels, upright, tight flower clusters. Plant habit upright, dense branching, branches gray-green and knobby; suitable for landscaping. Leaves dark green, glossy, with obtuse tips; venation raised underneath. Known more for its dark green leaves and evergreen characteristics than for its easily discolored flowers. It is susceptible to aphids and scales. This plumeria actually does well in zone 10a in southern California, and I have had one in zone 9b for 5 years with minimal (but always some) cold damage. I personally have found this species is actually MORE cold tolerant than the more commonly planted P rubra. It does sort of become deciduous at this extreme of its climate range, and it prone to rot if you're not careful... slower grower than P rubra, the more common species out here in So Cal. Flowering is far less frequent, as well. This plant tends to do well for very long time kept in a pot, which is not necessarily the case with most Plumeria rubra varieties. You can tell if from P rubra in that it is NOT deciduous (normally) and the leaves are more deeply divided with prominent veins that run nearly perpendicular to the long axis of the leaf. Leaves also shiny and a darker green and a bit smaller. As a tree it is more compact and much more densely foliated and P rubra. Flowers invariably white with slight yellowish centers. The name Singapore Plumeria was applied to Plumeria obtusa when it was introduced into Hawaii from Singapore in 1931 by Harold Lyon. The
