Collomia grandiflora (Large-Flowered Collomia) [20 Seeds]


Germination Information: Note that these seeds have a different growing cycle than many annuals. For best results, sow directly in the garden (just barely cover the seeds) in summer to early fall, so the seeds can get a period of warm weather followed by a cold period. Seedlings usually appear during mild periods in winter or spring, then flower in summer.

Large-flowered collomia (Collomia grandiflora), also known as large-flowered mountain trumpet, has upright, reddish stems  topped in summer (mostly early) with clusters of peach-colored, trumpet-shaped flowers accented with blue-tipped anthers. I find the height can vary greatly, depending on the growing conditions: in rich, moist soil, it can reach to 3 feet or more; in dry conditions, it may reach only a foot or so. You may want to try it in a corner of your vegetable garden or an out-of-the-way bed the first year to see how it performs in your particular conditions; then let it self-sow and move the young seedlings or cut the somewhat sticky seedheads when they turn brown and shake them over the area where you want to plants to grow next year. However you handle it, large-flowered collomia is an interesting and unusual choice for early summer color, US native. Full sun. Annual.

Collected in mid- to late July 2023. At least 20 seeds. Unknown ecotype.
