Description

''Lewisia rediviva'' is a low-growing
perennial plant
In horticulture, the term perennial (''wikt:per-#Prefix, per-'' + ''wikt:-ennial#Suffix, -ennial'', "through the year") is used to differentiate a plant from shorter-lived annual plant, annuals and biennial plant, biennials. It has thus been d ...
with a fleshy taproot and a simple or branched base and a low rosette of thick fleshy linear leaves with blunt tips. The leaves are roughly circular in cross section, sometimes somewhat flattened on the adaxial (top) surface. The absence of an adaxial groove on the leaves distinguishes this from other ''
Lewisia'' species with overlapping ranges. The leaves often wither before flowers open.
The very short flower stems are leafless, tall, bearing at the tip a whorl of 5–6 linear bracts which are 5–10 mm long. A single proportionally huge flower appears on each stem with 5–9 oval-shaped sepals and many petals.
Each flower has between ten and nineteen petals that measure long. They range in color from whitish to deep pink or lavender. Flowering occurs from April through July.
At maturity, the bitterroot produces egg-shaped capsules with 6–20 nearly round seeds.

they can be peeled, boiled, and made into a jelly-like food.
