Dyckia sp. · Dyckia (Hardy Terrestrial Bromeliad)

The plant forms a dense, spherical rosette of numerous narrow, rigid, succulent leaves radiating outward in all directions, each tapering to a sharp spine-like tip with fine marginal teeth/spines visible along the edges - characteristic of Dyckia, a terrestrial bromeliad genus. The dark purplish-bronze to near-black coloration with reddish-orange tones at leaf bases/tips is typical of cultivated Dyckia hybrids (many popular cultivars like 'Cherry Coke' or 'Black Gold' show this coloring). The whitish speckled/scurfy trichomes visible on the leaf surfaces are also consistent with Dyckia or related Pitcairnioideae bromeliads. However, without seeing a flower spike, the base/offsets more clearly, or precise leaf margin spine spacing, I cannot confirm the exact species or cultivar - there are many Dyckia hybrids with similar dark coloring. Similar genera to rule out include Hechtia (also spiny terrestrial bromeliad) and Deuterocohnia, which have comparable rosette forms. A photo of the flower stalk, a close-up of the spine pattern along a single leaf margin, and the greenhouse tag information (partially visible but illegible) would help narrow this to species/cultivar level.

Light

Full sun to very bright light; Dyckia rosettes color up best and stay compact with strong direct light.

Water

Allow soil to dry out between waterings; drought-tolerant and prone to rot if kept wet, so water sparingly, especially in winter.

Nutrients

Light feeding with a dilute balanced or cactus fertilizer monthly during spring/summer growth; skip in winter.

Repotting

Repot every 2-3 years or when the clump outgrows its pot; these form dense offsetting clusters over time.

Soil media

Very well-draining cactus/succulent mix, ideally with extra grit or sand for sharp drainage.

Temp & humidity

65-85F; tolerates low to moderate humidity well and does not need misting -- this is a dry-climate terrestrial bromeliad, not a tropical epiphyte.

Temperature range

🌡️ 65-85F

Humidity range

💦 20-50%

Care group

🏷️ Bright & Dry

Toxicity

No known toxicity concerns, but leaf margins have sharp recurved spines -- handle with thick gloves to avoid cuts.

Pests & diseases

Generally trouble-free; watch for mealybugs or scale in leaf axils, and root/crown rot if overwatered or drainage is poor.

Propagation

Divide offsets (pups) from the base of the mother rosette once they have some roots, ideally at repotting time; can also be grown from seed but slower.
