Herbaceous Plants
A division of the Camden Park catalogues that is poorly defined. Annuals and perennial herbs were included here. This is retained but Annuals are also separately identified.
Dianthus montanus M.Bieb.
Johnson's Dictionary and Don describe Dianthus montanus M.Bieb. as bearing large, purple flowers, olive-coloured on the underside, with strongly-toothed petals. Probably the same species as Dianthus chinensis L. which see. Hortus Second relates Dianthus montanus to Dianthus seguièri Vill., synonym D. chinensis var. asper. ‘The European extension of D. chinensis, perhaps a distinct species differing in the panicled flowers, and wide-spreading calyx bracts.’ [Hortus].

Dianthus species unidentified [3]
Unidentified species. It seems likely that these were varieties of carnation or pink. See Dianthus caryophyllus L. and cultivar descriptions.
Dianthus splendens unidentified
Unidentified Dianthus species, probably a nursery name for an improved form of a common species.
Dicentra spectabilis (L.) Lem.
Fully hardy, clump-forming perennial with thick, fleshy roots, leaves up to 40cm long, composed of three, often deeply cut, leaflets, and arching, fleshy stems producing racemes of flowers, 2-3cm long, with rose-pink outer petals and white inner, in spring and summer. To 1.2m. [RHSE, Hortus].
Dictamnus albus L.
Fully hardy clump-forming perennial with white or pinkish-white flowers in early summer. There are a number of garden cultivars, with rosy-red to purplish flowers. To 90cm. [RHSE, Hortus].
Digitalis lanata Ehrh.
Fully hardy clump-forming biennial or perennial with dense, leafy racemes of pale cream or fawn flowers from mid- to late summer. To 60cm. [RHSE, Hortus].
Digitalis purpurea L.
Fully hardy, rosette forming, variable biennial with tall. one-sided spikes of purple, pink or white flowers, with paler spots inside, in early summer. To 2m. [RHSE, Hortus].
Digitalis purpurea L. var. alba
See Digitalis purpurea L. Alba is a naturally-occuring white-flowered form.
Digitalis purpurea L. var. maculata superba
Maculata superba is a distinctly spotted form. [Hortus]. Digitalis purpurea superba, a hybrid with pink and purple flowers, was introduced in 1842. [PD]. This is probably the ‘new spotted’ form ordered by Macarthur. Whether it is a true hybrid or a variety of purpurea with particularly prominent spots is unclear.
Dioscorea alata L.
Probably a species of Yam, such as Dioscorea alata, with edible roots. Dioscorea alata is a tuberous perennial, the tubers sometimes very large, weighing up to 40kg and 2 m or more in length. Widely grown as a food source in the Pacific Islands. [RHSD, Hortus].
Dioscorea elephantipes (L’Hérit.) Engl.
Frost-tender, slow-growing, deciduous, climbing perennial with a partially buried, pyramidal, heavily fissured woody tuber, blue-green, heart-shaped leaves and dark-spotted, greenish-yellow flowers in summer. [RHSE, Hortus].
Dipogon lignosus (L.) Verdc.
Half-hardy perennial twining climber with attractive purple-pink flowers in decorative clusters of 3-6 blooms during summer. To 3m. [RHSD, Hortus].
Distictis buccinatoria (DC.) A.H.Gentry
A borderline half-hardy vigorous climber with lance-shaped leaflets to 10cm long and racemes of tubular-salverform, purple-red flowers, with yellow towards the bases, particularly noticeable in the bud, from summer to autumn. To 25m. [RHSE, Hortus].
