| WAHLENBERGIA undulata - Giant Bell Flower |
Campanulaceae, native to mountains in Europe, Australia, and South Africa. Germination: Sow indoors at a temperature of 60-70° with no cover as light aids in germination. Expect germination in 15-20 days. As seeds are very small, it is not recommended to sow them outdoors. Growth: Transplant when there are at least two sets of true leaves. Space 12 inches apart in full sun to partial shade in a sandy, humus-rich, well-drained soil. Site in a sheltered location and deadhead to prolong the flowering season. Plants will overwinter in frost-free climates, but they are not usually long lived (2-3 years). Appearance and Use: A plant for borders, rock gardens, hanging baskets, and containers. Plant habit is that of a 2 foot tall cushion or mound that is covered in 1-1 1/2 inch, bell-shaped, bluish mauve, pale blue, or white flowers all summer long. Leaves are narrow and have wavy, undulating margins. |

"Now why do you think a plant would look like this? That’s how I’d always get caught up in this stuff. Botany by imagination," Susan Orlean, The Orchid Thief |
