ASPARAGUS 



ASPARAGUS 



ASPAEAGUS, ORNAMENTAL. Lilulcecf. The genus 

 Asparai^iis coiiicrisrs al.ouT l.'iH species, which are widely 

 dis[ii-rsi'il ill w anil "i- tmini-a! r'-gions, being particularly 

 abundant iu S. Afr. The species are of very various 

 habit. Some are climbers, some drooping or trailing, and 

 some erect-bushy. Many of them are highly prized for 

 their very graceful and fine foliage. Some species even 

 surpass the most delicate ferns in elegance of habit and 

 delicacy of spray. The foliage is really composed of leaf- 

 like branches (cladophylla) rather than of true Ivs. (see 

 Fig. 151, and the discussion of it). Although all are per- 

 ennial, the sts. of some kinds annually die down or cast 

 their Ivs. With the exception of A. verticillnlus, the fol- 

 lowing species must be grown under glass, except in 

 S. Fla. and S. Calif. They are of easy culture. Best 

 when propagated by seeds (which are usually freely pro- 

 duced), but are also multiplied by division and cuttings. 

 Roots generally tuberous. Mongr. by Baker, Journ. 

 Linn. Soc. U (187.5) ; account of cult, species by Watson.

 Mn. 8 : 151. — One of the most popular basket and decora- 

 tive plants, of easy cult. Prop, by division, but most 

 efficiently by seeds, which can be purchased. At a night 

 temi>. of 65° they germinate in 4-5 weeks. Int. to horti- 

 culture by Dammann & Co., Italy, in 1890, and named for 

 their collector, Herr Sprenger. There is a white-lvd. 

 variety. 



lilcidus, Lindl. Climber: tubers 1!4 in. long : sts. 4-0 

 ft., spiny, branching : Ivs. narrow and curved, 2 in. or 

 less long, 2-6 in a cluster, more or less deciduous : fls. 

 .small, white, axillary : berries pink or white. Hin. in 

 diam. China and Japan, where the tubers are eaten 

 (A.G. 13:78).— Needs warm treatment. 



AAA. Foliage filiform or thread-like.

 the type, because of the fewer and longer Ivs. Var. 

 declinitus, Hort., has drooping sprays. Var. cristiltUB 

 Hort., has forking-tasseled sprays. 



Comor6nsis, Hort. Similar to A. plumosus : more ro- 

 bust, darker green, softer foliage : berries globular.

crispus, Lam. (4. dfciimftois, Jacq., and Hort.). Tu-

 almost hair-like and annual, the branches zigzag : Ivs. 

 numerous, usually in close pairs, very short (J4in.), 

 glaucous-green : fls. white, with orange anthers : 

 berry large (J^in. long), oval, soft, brown, about

 a form of this species.
