Family - Asteraceae Stems - From massive taproot, single or multiple from base, to +70cm tall, with milky sap, simple, fistulose, herbaceous, glabrous to lanate or floccose-lanate on internodes.
Leaves - Alternate, grasslike, to +25cm long, -1.5cm broad at base, tapering from base to apex, lanate adaxially on midrib otherwise glabrous, sheathing. Inflorescence - Single flower head terminating stem. Peduncle expanding and hollow below involucre. Involucre - Phyllaries typically in 2 series, 5cm long, 6mm broad at base, tapering from base to apex, lanate (mostly at base), with prominent midvein, much longer than ligules.
Ray flowers - Fertile. Ligules yellow, to 3cm long, 3mm broad. Styles bifurcate, brownish. Achenes whitish in flower, becoming tan with maturity, 10-nerved, tuberculate, tapering to a long beak, to +3cm long when mature. Pappus a single series of plumose bristles to +1cm long, whitish. Receptacle flat in flower and reflexed in fruit as to give fruiting head a globose appearance.
Flowering - April - July. Habitat - Fields, meadows, waste ground, roadsides, railroads. Origin - Native to Europe. Other info. - This species is easily visible along roadsides and in fields during late spring and early summer. The big yellow flower heads nod at the end of the stems. The plant contains a very sticky milky sap that you don't want to get on you as it is a pain to remove. The fruiting heads of the plant resemble those of the genus Taraxacum but are much larger and actually quite striking to look at. Care should be taken not to willingly spread this plant however, as it is not native.

Inflorescence - Dense terminal corymbiform arrangement of flower heads. Peduncles glabrous. Involucre - 1cm in diameter, 5-6mm tall, cupulate. Phyllaries imbricate, 4mm long, -2mm broad, glabrous, with scarious margins, blunt to obtuse at apex and often erose.
Ray flowers - Absent. Disk flowers - Disk to +/-1cm broad. Corolla tube whitish-yellow, glabrous, +?-2.3mm long, 5-lobed. Lobes acute, .2mm long, yellow. Stamens 5, adnate at base of corolla tube. Anthers yellow, .8mm long, connate around style near apex of corolla tube, included. Style bifurcate, slightly exserted. Achene white in flower, 1mm long, glabrous, 5-angled. Pappus absent or a minute crown. Receptacle conic.
Flowering - July - September. Habitat - Meadows, fence rows, prairie margins, fields, roadsides, railroads, cultivated. Origin - Native to Eurasia. Other info. - Tansy has been used in the past as a remedy for many ailments. The plant is quite toxic and causes abortions and even death in most mammals.

Family - Apiaceae Stems - To +/-1m tall, glabrous, often glaucous, erect, herbaceous, fistulose, fragrant, branching near the apex, from a taproot. Leaves - Alternate, petiolate below, sessile above, 2-3 ternately compound, glabrous. Petioles expanded and sheathing at the base, to 13cm long. Leaflets entire, oblong to elliptic or oblanceolate, mucronate (commonly), +/-2.5cm long, +/-1cm broad, glaucous abaxially.
Inflorescence - Terminal and lateral compound umbels with +/-10 rays per umbel. Peduncles glabrous, to +/-10cm in fruit. Rays glabrous, -4cm long. Raylets 2-5mm long. No bracts subtending any of the rays. Flowers - Petals 5, yellow, spreading or (more commonly) inflexed, apiculate, to 2mm long. Stamens 5, exserted, erect to spreading. Filaments pale yellow, glabrous, to 2.5mm long. Anthers pale yellow, .5-.6mm long. Styles 2, +2mm long, spreading and twisted, glabrous, whitish at the base, purplish near the apex. Stylopodium green, thick. Ovary inferior, slightly compressed, glabrous, 2-locular. One seed per locule. Flowers have a tendency to be either pistillate (with reduced to no stamens) or staminate (with reduced pistil).
Flowering - May - July. Habitat - Rocky and dry open woods or upland woods, prairies, ledges along bluffs. Origin - Native to U.S. Other info. - This species can be found through Missouri but is most common in the Ozarks. The plant is easy to ID either in flower or vegetatively because of its big leaves, which have oblong and entire leaflets. In flower, of course, the yellow flowers are a good characteristic for ID as no other member of our flora has the plants distinct combination of yellow flowers and oblong leaflets.

This lovely sunflower forms largeattractive clumps up to a metre in height. The easiest way to distinguish Arrowleaf Balsamroot from other sunflowers is by the silvery-green arrow-head-shaped leaves.
Distribution The range of the plant extends from British Columbia and south to Colorado and central California. It is one of many sunflowers found in the Rocky Mountains. Habitat and Blooming Times Arrowleaf Balsamroot grows on well-drained soil in open woodland sites exposed to plenty of sunshine. It blooms from late May to July and grows Uses American Indians used the seeds to make a kind of flour called pinole.
Etymology Balsamorhiza, the genus name, means 'balsam root'. The specific epithet sagittata means 'arrow shaped' - a reference to the leaves of this plant, which are shaped like arrowheads.

It's always fun as well as very interesting to find growing in the wild a plant that we buy when back at home in order to have it in the gardens! Aubrieta is one of our favourites. It manages to bloom early, even in gardens in the UK, and this is because, in the wild, it grows high up in the mountains and is used to inhospitable conditions like the English spring, which punishes so many of the other early-flowering plants.
Distribution This neat plant with its beautiful m\uve flowers can be found in Crete, where the plants shown on this page were photographed. We have also seen wild Aubrieta in the Gargano Peninsula in Italy.
Habitat and Blooming Times Aubrieta deltoidea grows in rocky habitats high up in the mountains, where it forms pretty cushions of flowers from March to early June.

This member of the Solanaceae (Nightshade) family has as bad a reputation as the other members of the family that occur throughout Europe - although one alien species, Thorn Apple Datura stramonium, is naturalised in Europe, having been imported with fertilisers from South America.
Identification Atropa belladonna, a bushy perennial plant, growto a height of two metres and occasionally more. The pale green oval leaves are pointed and strongly ribbed, and the bell-like purple-brown flowers with five fused petals, 20 to 30mm long, produce shiny green berries that turn black when fully ripe.
Distribution In Britain, Deadly NIghtshade mainly occurs in southern and eastern parts, but it is a rare find. This plant occurs also on mainland Europe and western Asia as well as in northern Africa. Habitat Atropa belladonna is found mainly on lime-rich soil. Solitary specimens are occasionally found growing at the edgeof shaded areas where limestone chippings had been spread a few years earlier.
Blooming Times In southern Britain Deadly Nightshade blooms in June, July and August. Uses Although Deadly Nightshade has for manyyears been used as a medicine, the glossy black berries of this plant are a potent poison. Cosmetics were once made from this plant, and some people suggest that belladonna refers to the beneficial effects of facial creams based on this plant.

Astragalus tragacantha ssp. vicentinus - is one of the rare plants to be found in Cape St. Vincent Natural Park (Parque Nacional de Sudoeste Alentejano e Costa Vicentina) in the Algarve region of Portugal.
Sometimes known as Astragalus massiliensis this plant is recorded from southern France, Northern Spain and other parts of the western Mediterranean region. It is a coastal species and grows in sandy soils among scrub. At Cape St. Vincent this plant is found along the roadsides towards the lighthouse. It is an uncomfortable candidate for photography as it grows on stony ground among thorny shrubs and plants. It is also becoming harder to find as much of its habitat is being taken over as alternative car parking areas for visitors to this iconic part of Europe. Cape St. Vincent is Europe's most south-westerly point and attracts tourists by the coachload in the summer months.
Astragalus tragacantha flowers in March and early April. It forms low-growing pincushion-shaped plants. The flowers appear white from a distance, but on closer inspection are tinged with purple.

This gorgeous wildflower certainly lives up to its common name - Showy Milkweed. 'Showy' it most certainly is, and it is hard to miss if you catch sight of it growing along roadsides which is one of its favourite habitats.
The plant grows to well over a metre in height and has large, handsome dark green leaves which have conspicuous veins. The lovely pink flowers open in a perfect globe, and close inspection reveals their unique structure.
Unlike other members of the Milkweed family, Asclepias speciosa is not poisonous and has been used both as food and for its medicinal qualities. During the Second World War the soft downy seeds of Showy Milkweed were collected for use in military bouyancy aids and also as insulating material for flying-jackets.
Showy Milkweed grows in both dry and moist habitats and you are equally likely to find it in roadside ditches as well as along riverbanks. It flowers from May through to August.
