# Yellow Stonecrop (*sedum nuttallii*)

Yellow Stonecrop (Sedum nuttallii, also classified as Sedum nuttallianum) is a charming, low-growing annual succulent native to the rocky glades and barren plains of the south-central United States. Thriving where few other plants can survive, it hugs shallow soils on sandstone, granite, or limestone outcrops. During the spring, these resilient plants transform harsh rocky landscapes into vibrant carpets of golden yellow. As a succulent, it is highly adapted to drought, storing water in its fleshy, plump leaves to endure dry spells. This hardy pioneer species plays a vital ecological role by stabilizing thin soils and providing early-season nectar for a variety of native pollinators.

## Appearance

This delicate annual herb typically reaches heights of 5 to 15 cm, forming small, branched tufts. Its fleshy, succulent leaves are alternate, cylindrical to somewhat flattened, and often turn a vibrant reddish-bronze when exposed to intense sunlight or drought stress. In late spring, it produces clusters of small, star-like yellow flowers, each featuring four to five bright yellow petals, matching yellow stamens, and pointed green sepals.

## Taxonomy

- **Kingdom:** Plantae
- **Phylum:** Tracheophyta
- **Class:** Magnoliopsida
- **Order:** Saxifragales
- **Family:** Crassulaceae
- **Genus:** Sedum

## Interesting facts

- Despite growing in extremely thin soils that dry out completely, its CAM photosynthesis allows it to seal its breathing pores during the blistering day.
- It is an annual plant, meaning it completes its entire life cycle from seed germination to flowering and seed release within a single year.
- Its leaves act as miniature water reservoirs, swelling up during rains and turning a brilliant crimson during dry spells to protect against sunburn.

## Special abilities

- **CAM Photosynthesis:** Utilizes Crassulacean Acid Metabolism, allowing it to capture carbon dioxide at night and keep its pores closed during the hot, dry day to prevent water loss.
- **Sunscreen Pigmentation:** Produces red anthocyanin pigments under high-light or drought stress, shielding its delicate inner tissues from intense sun damage.
- **Rapid Seed Cycle:** Completes its entire lifecycle within a few months of spring, setting hardy seeds that lie dormant to survive harsh summer droughts.

## Measurements & details

- **Length:** 5+ cm
- **Weight:** 0.001+ kg

## Diet & Feeding

As an autotrophic plant, it generates its own energy through photosynthesis, utilizing sunlight, carbon dioxide, and water while absorbing key minerals from sparse, rocky soils.

- **Primary Foods:** Sunlight, Carbon dioxide, Water, Soil minerals
