Mandevilla is a genus of tropical and subtropical flowering vines that belongs to the family Apocynaceae and the sub-family Apocynoideae. It is a frost-tender perennial plant with shiny leaves and eye-catching blooms available in shades of crimson, pink, yellow, purple, cream, and white.
The flowers generally bloom in summer and can stretch into fall, though they bloom year-round in warm climates. The Mandevilla plants can be grown as perennials and should be planted in mid-to-late spring once the temperature is warm and the risk of frost has passed.
How To Grow Mandevilla From Seed
Growing Mandevilla from seeds is pretty easy though it is best achieved from fresh seeds. The seed pods should remain on the plant to dry before removing them.
Once the seed pods are dried, they will turn brown and begin to split open and will reveal fluffy and dandelion-like seeds. Once this happens, the seeds are ready to be collected. For better and faster results, soak the Mandevilla seeds in water for about twelve hours before sowing them in well-draining soil.
The seeds require shallow planting and covering lightly with soil. Keep them moist and warm, about 65 to 75 degrees. Also, could you place them in bright indirect light?. This would help the seeds germinate within a month.
