Papaveraceae: Poppy Family — Poppies

There are 5 different genera of poppies in the county. Eschscholzia, which includes the California Poppy, is the most common; the others are Papaver (which includes Fire and Wind Poppies), Argemone (Prickly Poppy), Dendromecon (Bush Poppy) and Romneya (the widely-cultivated Coulter’s Matilija Poppy)

Bush Poppy – Dendromecon rigida

Blooms:

Apr–June

Plant Height:

1–3 m

Flower Size:

Large

Origin:

Native

Habitat:

Dry slopes

Notes:

This is an open, leafy shrub. Its bowl-shaped flowers are immediately recognizable as poppies, with 4 petals (occasionally 6) and multiple stamens. Leaves are simple, up to 10 cm long and 2.5 cm wide.

California Poppy – Eschscholzia californica

Blooms:

Feb–Sept

Plant Height:

5–60 cm

Flower Size:

Large

Origin:

Native

Habitat:

Grassy and open areas

Notes:

The state flower of California, this needs no comment except to different it from other members of its genus. This species is distinctive in having a spreading, disk-like rim on the receptacle (immediately beneath the petals). This rim is 0.5–5 mm wide (the other species have no rim or one that is less than 0.3 mm) and remains clearly visible at the base of the fruit. The flowers are variable in appearance; the petals being either uniformly orange or yellow to yellow-orange with an orange base. Leaves are generally finely dissected.

Tufted Poppy – Eschscholzia caespitosa

Blooms:

May–June

Plant Height:

5–30 cm

Flower Size:

Large

Origin:

Native

Habitat:

Dry flats and brushy slopes

Notes:

Similar in appearance to California Poppy (Eschscholzia californica) but the flowers are smaller and the spreading disk-like rim at the base of the petals is either absent or so small (< 0.3 mm) as to be virtually indiscernible. Flowers are yellow to yellowish-orange, occasionally with an orange-spotted base. The buds are erect and glabrous (an important point to note when comparing this species with San Benito Poppy (Eschscholzia hypecoides) which has buds that are nodding and generally hairy).

San Benito Poppy – Eschscholzia hypecoides

Blooms:

Mar–June

Plant Height:

5–30 cm

Flower Size:

Large

Origin:

Native

Rare or endangered?:

Yes – 4.3

Habitat:

Grassy areas in woodland & chaparral

Notes:

Similar in appearance to Tufted Poppy (Eschscholzia caespitosa) — with the disk-like rim at the base of the petals either absent or so small (< 0.3 mm) as to be virtually indiscernible. Flowers are yellow to yellowish-orange, occasionally with an orange-spotted base. The buds are nodding and generally hairy (an important point to note when comparing this species with Tufted Poppy which has buds that are erect and glabrous). The whole plant is sparsely hairy, unlike the other Eschscholzia found in the county. Found on the eastern slopes of the Santa Lucias and in the Inner Coast Ranges.

Fire Poppy – Papaver californicum

Blooms:

Apr–May

Plant Height:

20–60 cm

Flower Size:

Large

Origin:

Native

Habitat:

Burns

Notes:

As the common name suggests, this is a fire follower, generally found only in areas that have recently burned.  It has 4 or 5 orange to brick-red petals, generally slightly wrinkled, with a greenish basal spot.  There is no style but the stigma is head-like (a characteristic of the Papaver that helps differentiate them from the Eschscholzia).

Wind Poppy – Papaver heterophyllum

Blooms:

Apr–May

Plant Height:

40–60 cm

Flower Size:

Large

Origin:

Native

Habitat:

Grassy or brushy slopes

Notes:

This delicate poppy has a single flower with orange petals and a deep purple base. The stamens have red-purple filaments and yellow anthers. Note the short, fuzzy style and the prominent head-like stigma.  Uncommon.

Corn Poppy – Papaver rhoeas

Blooms:

June–July

Plant Height:

30–80 cm

Flower Size:

Large

Origin:

Eurasia

Habitat:

Cultivated, occasional escape

Notes:

This poppy is unmistakable with its vivid red flowers, often with a white-rimmed black spot at their base. Widely cultivated and occasionally escaping; it is unclear whether the species has actually become naturalized in California. This poppy is very common in Europe and it flourished in the disturbed ground between the trenches in the First World War — leading to its adoption as the symbol of remembrance for those killed during the war.

Prickly Poppy / Chicalote – Argemone munita

Blooms:

May–Aug

Plant Height:

6–15 dm

Flower Size:

Large

Origin:

Native

Habitat:

Dry, disturbed places

Notes:

This an erect plant with flowers similar to Coulter’s Matilija Poppy (Romneya coulteri), though a little smaller (2.5–5 cm across) and more crinkled. The plant is covered throughout in stiff spines. The leaves are thistle-like and 5–15 cm long, quite different from the those of Coulter’s Matilija Poppy.

Coulter’s Matilija Poppy – Romneya coulteri

Blooms:

Mar–July

Plant Height:

10–25 dm

Flower Size:

Large

Origin:

Native (Santa Barbara County)

Habitat:

Widely cultivated, occasional garden escape

Notes:

This spectacular poppy is a large shrub or sub-shrub with gray-green, glaucous, deeply cut leaves. The flowers are large (6–10 cm across) with pure white, wrinkled petals and many bright yellow stamens. It cannot be mistaken for anything else except possibly for Prickly Poppy (Argemone munita) which has similar, though smaller, flowers and very different leaves. The flowers are the largest of any plant native to California.
