Notice

Colin Mills, compiler of the Hortus Camdenensis, died in late November 2012 after a short illness. As he always considered the Hortus his legacy, it is his family's intention to keep the site running in perpetuity. It will not, however, be updated in the near future.

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.

Mandevilla splendens (Hook.) Woodson

Tender, tuberous rooted herbaceous climber with broad leaves and white flowers, suffused with pink.  There are a number of garden forms with more brightly coloured flowers.  [RHSD, Hortus]. 

 

Maranta species unidentified

A genus of about 20 evergreen, rhizomatous perennials from Central and South American rainforests.  In temperate climes they they are mainly grown for their highly decorative leaves as pot specimens.  

 

Micranthus alopecuroides (L.) Rothm.

Frost-tender cormous perennial with lance-shaped or linear leaves and a sometimes branched stem bearing numerous, small, irregular, slightly scented, individually inconspicuous pale to deep blue flowers, the outer lobes sometimes tipped with red, in summer.  To 40cm.  [RHSD, CECB].

Moraea aristata (D.Delaroche) Asch. & Grabn.

Cormous perennial with a solitary, linear, flat, basal leaf and occasionally branched stems bearing white flowers with conspicuous, green, blue or violet central eyes on the outer tepals, in spring.  To 35cm.  [RHSE, Hortus, CECB].  

Moraea collina Thunb.

Cormous perennial with a solitary, linear, basal leaf, sheathing the wiry stem for half its length, and cup-shaped, scented, bright red, yellow, peach or pink flowers in succession from spring to summer.  To 50cm.  [RHSE, CECB, Hortus].

Moraea fugax (D.Delaroche) Jacq.

Cormous perennial with a solitary, occasionally two, very long, wiry leaf below the inflorescence, and a stem, to 40cm, bearing up to 4, short lived, sweetly-scented, white, yellow or lilac flowers, with a bright yellow patch at the base of the outer segments, in late summer.  The flowers open at mid-day, fading in the evening.  [RHSD, CECB, Hortus, Grey].  

Moraea ramosissima (L.f.) Druce

Cormous perennial with numerous semi-erect, narrowly linear basal leaves and many-branched stems bearing bright yellow flowers from spring to summer.  To 1.2m.  [RHSE, Hortus, CECB].

Moraea species unidentified

Unidentified species, no description.

Muscari botryoides (L.) Bak.

Fully-hardy, slender bulbous perennial with semi-erect, narrowly spoon-shaped leaves and dense racemes of spherical bright blue flowers with white mouths in spring.  To 20cm.  [RHSE, Hortus].

Muscari comosum (L.) Mill.

Frost-hardy bulbous perennial with spreading leaves and tassels of violet flowers in spring.  To 60cm.  [RHSE, Hortus].

Muscari muscarimi Medik.

Half-hardy bulbous perennial with grey-green leaves to 20cm, an erect to prostrate flowering stem, to 20cm, and musk-scented, pitcher-shaped, greyish-white flowers with a bluish tinge, becoming paler or brownish with age, in spring.  To 20cm.  [RHSD, Hortus].

Muscari muscarimi Medik. var. dark blue

See Muscari muscarimi Medik., synonym Muscari moschatum Willd., for more information on the species.  The Musk hyacinth, Muscari muscarimi Medik., is a very distinctive plant, and I have found no reference to the dark blue colour form listed here, although the other colour forms are possible as the species is somewhat variable, and almost white flowers and forms with a distinct pale blue tinge to the flowers are known.  The three Muscari moschatum colour forms listed in the catalogues could also be Muscari botryoides as flowers in shades of blue, pink and white have been known since at least the early 19th century and probably much longer.

Muscari muscarimi Medik. var. pale blue

See Muscari muscarimi Medik., synonym Muscari moschatum Willd., for more information on the species.  The Musk hyacinth, Muscari muscarimi Medik., is a very distinctive plant, and I have found no reference to the dark blue colour form listed here, although the other colour forms are possible as the species is somewhat variable, and almost white flowers and forms with a distinct pale blue tinge to the flowers are known.  The three Muscari moschatum colour forms listed in the catalogues could also be Muscari botryoides as flowers in shades of blue, pink and white have been known since at least the early 19th century and probably much longer.

Muscari muscarimi Medik. var. white

See Muscari muscarimi Medik., synonym Muscari moschatum Willd., for more information on the species.  The Musk hyacinth, Muscari muscarimi Medik., is a very distinctive plant, and I have found no reference to the dark blue colour form listed here, although the other colour forms are possible as the species is somewhat variable, and almost white flowers and forms with a distinct pale blue tinge to the flowers are known.  The three Muscari moschatum colour forms listed in the catalogues could also be Muscari botryoides as flowers in shades of blue, pink and white have been known since at least the early 19th century and probably much longer.

Muscari neglectum Guss. ex Ten.

Fully-hardy bulbous perennial with semi-erect, almost cylindrical leaves and dense racemes of blue-black flowers with white mouths in spring.  To 20cm.  [RHSE, Hortus].
