Better known as Frangipani, it is a delightful small tree for a garden with a semi-tropical look, usually reaching a height of around 4m, though with great age they seem capable of growing to 8-10m.
The leaves of Plumeria rubra are 10-42 cm long and 4-14 cm wide with the widest point at the center or tip of the leaf blade. In this species the tip of the leaves narrow to a sharp point in contrast to leaves of the other common species, Plumeria obtusa, which has more rounded leaf tips.
Plumeria Scarlet Knight has spicy clove fragrance with solid 3-4" dark purple red flower . Elliptical moderately overlapped petals with rounded tips. Petals are dark red, with gold center. Dark red bands on reverse with white veining. Spicy clove fragrance with excellent keeping quality with high tendency to fade.
Frangipani needs bright light to full sun for at least 5 hours of direct sun each day.
Keep soil evenly moist during summers. Water sparingly in winter, when plant is resting. Yellowing leaves are a sign of over watering.
Moderate humidity is good for the plant. Place the pot on a tray of wet pebbles to raise the humidity around the plant. Misting is also a good idea in summer. With plumeria care should be taken to mist the foliage, not the flowers.
Feed the plant with high-phosphorus fertilizer before summer begins to promote blooming.
Plumeria rubra makes a beautiful potted house plant. They grow well in pots, flowering reliably every summer.

Plumerias need at least 5 hours of direct sun in a day. Keep soil moist during the summers but water sparingly during the winters. You should water the plumeria deeply and make sure it is dry before watering it again. Generally you can water it twice a week during summers.
Not enough water or too much water can lead to the leaves turning yellow. Because they need regular, even amounts of water, dry spells can cause plumeria leaves to turn yellow and cause them to drop off the plant, with the bottom leaves suffering first. If you see yellowing leaves, check the soil by digging down several inches making sure it isn't wet.
Plumerias can be pruned in later winter or early summer before the new growth starts.
