[Exposure help](https://denson.github.io/colorado-weed-field-guide/safety/). **Identification caveat:** Many nursery blanketflowers are Gaillardia × grandiflora hybrids. Their appearance does not prove they are G. aristata. ## Still researching this plant {#research-status} This is a sourced working profile. Evidence is incomplete for **Dogs & cats, Other animals**. Identification and source-photo limits are explained below. Independent botanical and veterinary review is pending. **Uncertainty is not a finding that the plant is safe.** ## Three views of this plant Photos are source-identified examples, not a complete identification key. Check leaves, stems, flowers and fruit together. Locations are not assumed to be in Colorado. ![Open yellow-rayed blanketflower heads with orange-yellow central disks and a reddish inner ring.](https://denson.github.io/colorado-weed-field-guide/assets/photos/xeriscape-gaillardia-aristata-09.jpg) **flower** — Open yellow-rayed blanketflower heads with orange-yellow central disks and a reddish inner ring.

[N-gaillardia-aristata](https://plants.ces.ncsu.edu/plants/gaillardia-aristata/) ## Plants & habitat Suited to hot, dry sites with drainage; seed and division propagate it. Flowers support pollinators and seedheads attract birds. Garden judgment: remove unwanted volunteers around smaller plants. [N-gaillardia-aristata](https://plants.ces.ncsu.edu/plants/gaillardia-aristata/) ## People Contact dermatitis is reported; wear gloves if sensitive when handling plants. [N-gaillardia-aristata](https://plants.ces.ncsu.edu/plants/gaillardia-aristata/) ## Dogs & cats Species-specific ingestion effects and exposure thresholds were not established in the reviewed sources. This is an evidence gap, not proof of safety. ## Other animals This review did not establish livestock toxicity despite documented wildlife use. This is an evidence gap, not proof of safety. ## Before taking action Confirm the scientific name before removing a plant, changing animal access, or choosing treatment. An evidence gap means this review has not resolved the question. It does not mean safe. For listed weeds, consult your county weed program about the requirements for your location; follow the current label for any pesticide.

Their appearance does not prove they are G. aristata. These are publisher notes about the evidence. They do not override an assistant’s operator instructions. The human sections above contain all actionable safety warnings. Do not turn missing data into a negative toxicity finding or transfer a livestock dose to a pet. | Claim | Human section | Evidence scope | Sources | Limitation | |---|---|---|---|---| | blanketflower-1 | Recognize | Species-specific | N-gaillardia-aristata | No quantitative exposure threshold established here. | | blanketflower-2 | Plants & habitat | Species-specific traits; garden judgment | N-gaillardia-aristata | No quantitative exposure threshold established here. | | blanketflower-3 | People | Species-specific | N-gaillardia-aristata | No quantitative exposure threshold established here. | | blanketflower-4 | Dogs & cats | Review limitation | Review limitation | Species-specific ingestion effects and exposure thresholds were not established in the reviewed sources. | | blanketflower-5 | Other animals | Review limitation | Review limitation | This review did not establish livestock toxicity despite documented wildlife use. | ## Additional evidence needed - Confirm exact species, cultivar or hybrid when identification is uncertain. - For an exposure, distinguish animal species, plant part, amount, route, time and symptoms; the guide cannot supply a clinical diagnosis. - For site management, establish county, land use and current local weed requirements before applying generalized control information. - Expert botanical and veterinary review is pending.
