The genus Asparagus, which includes the edible vegetable Asparagus officinalis, also includes a number of species and varieties grown indoors for their attractive feathery foliage. Asparagus Sprengeri is the most popular house-plant that has pliable, drooping stems as much as 3 feet long. Flowers which are small, sometimes fragrant are often followed by red, orange or purple berries. Although the fine needle-like leaves of some species have the common name as fern, they actually belong to the lily family and are not ferns.
Germination Temperature (°F)
Water plentifully as often as necessary to keep potting mixture thoroughly moist but never allow the pot to stand in water. During the rest period give the plant only enough water to keep the mixture from drying out.
Apply standard liquid fertilizer every 2 weeks throughout the active growing period.
Use a soil-based potting mixture, re-pot in Spring into pots one size larger until they are in the largest convenient size. When grown in hanging baskets, they should be top-dressed with fresh mixture in Spring.
Divide overcrowded clumps in Spring. Remove any excess mixture from tuberous roots and separate them with a sharp knife. Plant clumps in 3 inch pot of soil-based potting mixture and treat as mature specimens. Seed germinates well when chipped or soaked in Spring.
Bright light is essential for Asparagus plants but never subject them to direct sunlight which can badly scorch the leaves.
If dead or damaged fronds are unsightly, cut them off with sharp scissors.
Spray twice a week in Summer, daily in hot weather and once a week in Winter. Stand pot on a saucer of pebbles almost covered with water to keep up humidity.
All parts of the oleander (Nerium oleander), a beautiful Mediterranean-native flowering shrub, are poisonous. Ingesting oleander leaves can cause gastrointestinal, cardiac, and central nervous system problems and possible death.
