SOIL TYPE
Well-drained. The 'Butterbloom' Turpentine Bush (Ericameria laricifolia 'Butterbloom') requires a soil with excellent, rapid drainage as its primary characteristic. It naturally thrives in poor, dry, and low-organic content soils, including sandy, rocky, granitic, and limestone soils. The ideal pH range is neutral to slightly alkaline, specifically between 6.6 and 7.8. Amending the soil heavily is unnecessary, as the plant is well-adapted to challenging, unamended native conditions.
MAINTENACE TIPS
Maintain the plant with very little effort. It is low-maintenance and drought-tolerant, requiring little to no water once established. Avoid overwatering to prevent overgrowth and encourage a dense form. Mulch with inorganic materials like pebbles if desired, rather than organic ones.

FLOWER CHARACTERISTICS
The 'Butterbloom' Turpentine Bush, a cultivar of the species Ericameria laricifolia, produces showy, bright golden yellow, daisy-like composite flowers. These flowers, characteristic of the Asteraceae (daisy) family, are borne in dense terminal clusters that can nearly cover the entire plant in the fall. Each small flower head typically contains both yellow ray florets and yellow disc florets. The 'Butterbloom' selection is specifically noted for its abundant flowering performance and rich green, aromatic, needle-like foliage.
FRUIT/SEED
The 'Butterbloom' turpentine bush (Ericameria laricifolia 'Butterbloom') produces a small, dry, single-seeded fruit known as an achene. This fruit is narrowly obconic (cone-shaped with the narrow end at the base), somewhat flattened, angular, and covered in white, soft hairs (sericeous). The achene measures approximately 3.5–4 mm in length and features a persistent pappus (a dense tuft of tan to off-white bristles or capillary hairs) at its apex, which aids in wind dispersal. The clustered seed heads appear tan or light brown when ripe and resemble small, packed dandelions before they are dispersed.
SUN EXPOSURE
Full Sun
POLLINATORS
The 'Butterbloom' turpentine bush (Ericameria laricifolia 'Butterbloom') is a vital late-season native plant for numerous pollinators, including various species of native bees and butterflies, which are highly attracted to its abundant, nectar-rich yellow flowers. The plant also serves a crucial role as a specific larval host for the brown hooded owlet moth (Cucullia convexipennis), and the Great Purple Hairstreak. Beyond insects, the resulting seeds provide an important food source for many seed-eating birds, while the shrub's dense form offers cover and nesting sites for birds and small mammals. The aromatic foliage typically deters browsing by large animals such as deer.
PRUNING TIPS
Prune only as needed to maintain shape or control size, ideally in late winter or early spring. Avoid pruning after August to prevent cutting off the developing flower buds, which are set for the fall bloom. If the shrub becomes too large or leggy, a severe pruning to the ground in winter will stimulate new growth the following spring.
