A mandrake is the root of a plant, historically derived either from plants of the genus "Mandragora" found in the Mediterranean region, or from other species, such as "Bryonia alba", the English mandrake, which have similar properties.
 The plants from which the root is obtained are also called "mandrakes".
 Mediterranean mandrakes are perennial herbaceous plants with ovate leaves arranged in a rosette, a thick upright root, often branched, and bell-shaped flowers followed by yellow or orange berries.
 They have been placed in different species by different authors.
 They are very variable perennial herbaceous plants with long thick roots (often branched) and almost no stem.
 The leaves are borne in a basal rosette, and are very variable in size and shape, with a maximum length of 45 cm .
 They are usually either elliptical in shape or wider towards the end (obovate), with varying degrees of hairiness.
Leucas zeylanica, commonly known as Ceylon slitwort, is a small, terrestrial, herbaceous, annual, erect or sometimes tufted, hispid and aromatic plant of the subfamily Lamioideae of family Lamiaceae.
 It is native to Tropical Asia and Malaya.
 Botanical synonyms include "Leucas bancana" Miq., "Phlomis zeylanica" Linn., and "Spermacoce denticulata" Walp.
 It is also known as ගැටතුඹ ("geta-tumba") in Sinhala, "halkusha" in Bengali, "guldora" in Punjabi, "kulnnphul" in Gujarati, "goma madhupati" in Hindi, "kubo" in Sindhi, "bhutamari" in Oriya, "bahuphul" in Marathi, "thumbai" in Tamil, "thumbe" in Kannada, "thummi" in Telugu, and "thumba" in Malayalam.
Rhizoctonia solani (teleomorph: Thanatephorus cucumeris) is a plant pathogenic fungus with a wide host range and worldwide distribution.
 It was discovered more than 100 years ago.
 "R. solani" frequently exists as thread-like growth on plants or in culture, and is considered a soil-borne pathogen.
 "R. solani" is best known to cause various plant diseases such as collar rot, root rot, damping off, and wire stem.
 "R. solani" attacks its hosts when they are in their early stages of development, such as seeds and seedlings, which are typically found in the soil.
 The pathogen is known to cause serious plant losses by attacking primarily the roots and lower stems of plants.
 Although it has a wide range of hosts, its main targets are herbaceous plants.
 "R. solani" would be considered a basidiomycete fungus if the teleomorph stage were more abundant.
 The pathogen is not currently known to produce any asexual spores (conidia), though it is considered to have an asexual lifecycle.
 Occasionally, sexual spores (basidiospores) are produced on infected plants.
 The disease cycle of "R. solani" is important in management and control of the pathogen.
Cicuta, commonly known as water hemlock, is a small genus of four species of highly poisonous plants in the family Apiaceae.
 They are perennial herbaceous plants which grow up to 2.5 m tall, having distinctive small green or white flowers arranged in an umbrella shape (umbel).
 Plants in this genus may also be referred to as cowbane or poison parsnip.
 "Cicuta" is native to temperate regions of the Northern Hemisphere, mainly North America and Europe, typically growing in wet meadows, along streambanks and other wet and marshy areas.
 These plants bear a close resemblance to other members in the family Apiaceae and may be confused with a number of other edible and poisonous plants.
 The common name hemlock may also be confused with poison hemlock ("Conium maculatum").
Herbaceous plants (in botanical use frequently simply herbs) are plants that have no persistent woody stem above ground.
 Herbaceous plants may be annuals, biennials or perennials.
Alkanna is a genus of herbaceous plants including about 60 species of the family Boraginaceae.
The term soft landscape is used by practitioners of landscape design, landscape architecture, and garden design; and gardeners to describe the vegetative materials which are used to improve a landscape by design.
 The corresponding term "hard landscape" is used to describe construction materials.
 The range of soft landscape materials includes each layer of the ecological sequence: aquatic plants, semi-aquatic plants, field layer plants (including grasses and herbaceous plants) shrubs and trees.
Phlomis is a genus of over 100 species of herbaceous plants, subshrubs and shrubs in the family Lamiaceae, native from the Mediterranean region east across central Asia to China.
 Common names include Jerusalem sage and lampwick plant.
A herbaceous border is a collection of perennial herbaceous plants (plants that live for more than two years and are soft-stemmed and non-woody) arranged closely together, usually to create a dramatic effect through colour, shape or large scale.
 The term herbaceous border is mostly in use in the United Kingdom and the Commonwealth.
 In North America, the term perennial border is normally used.
Smilax" sect.
 "Nemexia is a section of plants in the family Smilacaceae.
 It consists of the herbaceous plants within the genus "Smilax".
 "Smilax" species fall into two groups with distinctive morphologies: one group has woody perennial stems with thorns and a vining habit, while the other group has herbaceous stems that die back to the ground each winter.
 "S." sect.
 "Nemexia" is the taxon that comprises the herbaceous species.
 In the past it was often a genus of its own under the name Nemexia and taxonomists still need further study of the species of "Smilax" to determine its proper rank.
 However the widely accepted taxonomic system of the "Flora of North America" does not recognize "Nemexia", nor does the AP-site.
 Thus "Nemexia" is not currently considered an accepted genus taxon by most plant taxonomists.

Question: Are Alkanna and Phlomis both herbaceous plants?
Answer: yes
