Cubanola Species, Campanita Criolla, Dominican Bellflower, Tree Lily

I’ve been growing this plant for 1 year. It was rather sad-looking at acquisition time but it is recovering well. I detected no fragr...Read Moreance at midday; will have to try during mornings and evenings. Leaf uppers are shiny and leathery. It requires overwintering in z9a, with very limited watering to avoid root rot. Does well in containers, which is ideal when growing outside its hardiness zone.

It took a few months for the seeds I had to germinate using a moist coffee filter paper and a zip lock bag. About 20% of seeds germinated...Read More. Those have grown well and are about 8”/20cm tall 1.5 years after germination. The leaves are mid green with a grey/silver tint where there exposed to direct sun. Seem to like dappled sun and moist soil which is friable (with peat moss or coconut choir added). I’ll post again when in flower.
Update; I repotted two of the seedlings in seperate 12” pots. One in a shadecloth area, and one on a balcony near a airconditioning fan. The first has grown twice as big as the second, but the second is the first to flower (in autumn/fall 2 years after seed germination), maybe because it was getting warmer air from the air-con. Easier to grow than a Brugmansia (not attacked by spider mites), and lusher foliage (reminds me of a aribica coffee shrub).
The unopened flower is 7.5”/20cm long.
Update #2; The plants are now 3 years old (grown from seed). Both now have 8+ flowers on them, which opened at mid autumn/fall. Soon after the sun goes down, they give off a strong sweet cinnamon fragrance (even if cut and placed upside down in a vase). A single flowers’ scent carries over 6’/1.8m indoors. Whilst not like chocolate, as some ads have claimed, it’s pleasant, a bit like a chai latte! As far as fragrance goes, in my option, it’s much nicer and stronger than the ‘Queen of the Night’ (epiphyllum oxypetalum), but maybe not quite as good as the amazing scent of the Ric Rac Orchid Cactus (Epiphyllum anguliger) - both flower around the same time, but the bellflower lasts longer.
After growing quickly to about 0.6m/2’ they both have slowed down, maybe because of the effort needed to produce the relatively large flowers they have.
Update #3; Plants are 4 years old. Both are doing fine, and are around the same hight (0.6m/2' tall), but with longer branches, but the one in a shadier position (getting about 6 hours of dappled sun) gets more flowers, and the other is more leggy.
Germinate some more of my 4 year old seeds. This time I started them mid-summer by soaking them for 3 days on a heat mat, then transferring them to a moist unbleached coffee filter paper in zip lock bag, and onto moist coir within a day or two of germination using a toothpick and wet finger. Seeds still viable, with much better germination - 90% germinated within the first 35 days.
Update #4
Another year has past. I notice the seedling are very slow to grow in a seedling tray, best results came from planting the seed once sprouted directly to a 13.5 cm (5.4 inches) pot. I’ve just added my latest photo of my 5 year old plant. It loves sheep manure, which increased the flower (and fragrance) production many times over. It’s still in the same large pot, and hasn’t growth much higher, but is spreading out. It seem to it flowers from midsummer till late autumn.

Endemic plant of the Dominican Republic in the Caribbean. It grows in the north and the east part of the country, near the beach, in full...Read More sun conditions, and in the undershrubs of the low land humid forest, in full shade. Average growing temperature should be 24-26 centigrades. Highly fragant. Grows well in pots, one gallon or more.
