Calendula : Datura Triple Yellow Trumpet


(Other common names: Jimson Weed, Horn of Plenty, Devil’s Trumpet, Thorn Apple). A delightful and easy to grow plant, suitable for a container or the garden! These fast growing Datura have single, white trumpet shaped blooms with lilac/purple highlights in the center. Blooms are about riple White Devil's Trumpet (datura) seeds PLUS planting instructions, including a color photo for seedling id. The mix is approximately equal number of each color, but since it is a mix, I can't guarantee the exact percentage you will get of each color. These are fresh seeds that I have planted myself with excellent germination results. They do take 21+ days for germination and need it HOT. You will be getting seeds for fragrant Datura with double purple, triple white and triple yellow blooms. The blooms face upward and the plants are a bush reaching 3 feet tall and 2-3 feet wide. If the flowers weren't enough, the double purple plants also sport glossy, dark purple stems. Datura is a perennial in zones 8 and warmer and usually lives about 4 or 5 years under good conditions. Treat as a fast growing, self-sowing annual in other areas. Datura’s produce several seed pods and thrive in high heat, particularly in humid areas. They are very rapid growing plants in full sun or partial shade. Datura’s can be started in pots or directly in the garden after last frost; they also make a wonderful container plant on patios or decks. They are easy to transplant when small, but more difficult once established in the garden. The plants/flowers/seeds are poisonous.
