Large Flowered Agoseris

Pale Agoseris (Agoseris glauca) should be watered regularly during its season of active growth. A light, deep watering every 3-4 days for a few minutes should be enough. During the hot summer months, water it more frequently, calming down when temperatures start to cool in fall. Avoid over-watering your Pale Agoseris - if you are unsure if your plant needs water, check the soil first. If the top inch or 2 of soil are dry, then it's time to water.

Pale Agoseris is native to western North America, from Alaska to California and east to Colorado. It prefers full sun or light shade and is not tolerant of deep shade. It needs a minimum of 6 hours of sunlight daily during the growing season. In some areas, it can tolerate more sun when treated with adequate water. In hot and dry locations, some shade should be provided. In all locations, it should be protected from windy conditions.

Pale Agoseris (Agoseris glauca) should be pruned at the end of the flowering season, or throughout the growing season to remove dead flowers or stems. Pruning can be done 1 of 2 ways - light pruning, which should only consist of pruning single stems or removing dead flowers; or heavy pruning, which requires cutting back the stems to a few inches to encourage growth. Light pruning should be done sparingly, as it can inadvertently reduce flowering the following year. Heavy pruning can be done twice per season - once after flowering and again in late summer to encourage more blooming and growth the following year. When pruning Agoseris, it is important to sterilize your tools with rubbing alcohol or diluted bleach between each cut to avoid transferring disease to your plant.
