Bulbous and Tuberous Rooted Plants
A division of the Camden Park catalogues that is not clearly defined. Some of the more important families of the Hortus are included here, Amaryllidaceae, Iridaceae and Liliaceae. It also contains a wide assortment of other plants with a modified stem or root that acts as a storage organ. Such plants are usually deciduous and have a distinct dormancy period. Shrubs and trees are not included, but there is some overlap with herbaceous plants.
Gladiolus x colvillii Sweet
‘Colvillii’ hybrids are early flowering, with small, widely open flowers, the type having crimson and white flowers and growing to 60cm. Many cultivars have been produced, with dark pink, yellow or white blooms in late spring. The ‘Nanus” hybrids, still popular today, were later developed from them. [RHSD, Hortus, PD].
Gladiolus x gandavensis Van Houtte
A hybrid gladiolus with broad leaves and long spikes of flowers in a range of colours, often streaked and marked with contrasting colour. The accompanying figure shows flowers with ground colours of white, pale yellow, pale pink through to deep red.
Gladiolus x insignis Paxt.
Gladiolus carneus x Gladiolus cardinalis hybrid. ‘A handsome hybrid, with very long, narrow leaves, and apparently drooping flower stalks, on which the blossoms are borne chiefly on the upper side. Flowers of a rich and reddish crimson hue, having a dash of bluish purple in the centre of the lower petals.’ The plant was drawn at Lucombe and Pince’s nursery. They had purchased Colville’s stock some years earlier. [MB p.223/1840]. Paxton’s Dictionary also describes it as crimson, growing to 45cm, while the Floricultural Cabinet describes it as deep rose-crimson. [FC p.257/1851]. ‘A good variety in the ‘Ramosus’ tribe, together with G. splendens.’ [Gard. Chron. 1851].
Gladiolus x nanus Hort.
Each corm produces 2-3 slender spikes, up to 35cm long, with up to 7 loosely arranged flowers in a range of colours on each stem. [RHSE]. Spring flowering hybrids.
Gladiolus x ramosus Paxt.
Gladiolus cardinalis x G. oppositiflorus hybrid, with heavy and broad leaves and flowers of a rosy-blush colour, with heavy carmine stains on the three lower divisions. [Grey].
Gloriosa superba L.
Very variable species formerly thought to be at least three distinct species. Frost-tender, tuberous-rooted climbing perennial with glossy lance-shaped leaves which narrow to form terminal tendrils. The flowers have wavy-margined petals of red or purple, often yellow-edged or entirely yellow. Summer flowering. To 2m. [RHSE, Hortus].
Gloriosa superba L. var. virescens
See Gloriosa superba L. for information on the species. Virescens has deep orange and yellow flowers, the margins of the segments slightly undulated rather than crisped, as in the type Gloriosa superba. The variety grandiflora is most commonly met with in gardens. [RHSD, Hortus].
Griffinia hyacinthina Ker Gawl.
Bulbous perennial with oblong leaves and umbels of 9 or 10 white flowers, produced in summer, the upper segments tending to blue at the apex. The 4-5 leaves, to 15cm long, have lattice-like veining and are produced after the flowers. To 45cm. [RHSD, Baker Am.].
Habranthus robustus Herb. ex Sweet
Robust bulbous perennial with slender linear leaves which emerge in summer at about the same time as the stems that bear solitary, open funnel-shaped, pale pink flowers resembling a small Amaryllis belladonna. To 30cm. The largest of the Habranthus genus commonly grown. [RHSE, Hortus, Baker Am.].

Habranthus tubispathus (L’Hér.) Traub
Half-hardy, upright, bulbous perennial with narrow, linear leaves and a succession of flowering stems, each bearing a small, funnel-shaped, coppery red, orange or yellow flower, in summer. To 15cm. [RHSE, Hortus].
Hedychium coronarium J.G.Koenig.
Half-hardy, upright rhizomatous perennial with long lance-shaped leaves and terminal racemes of fragrant, butterfly-like white flowers, with greenish-white basal marks, in summer. To 3m. [RHSE, Hortus].
Hedychium gardnerianum Ker-Gawl.
Half-hardy perennial with lance-shaped leaves, to 40cm long and spikes of yellow flowers with bright red filaments. To 2m. [RHSD, FNSW].
