Helianthus tuberosus aka Jerusalem Artichoke
Taxonomy ID: 10232
Helianthus tuberosus, also known as Jerusalem artichoke, sunroot, sunchoke, wild sunflower, topinambur, or earth apple, is a highly variable plant that is native to central North America. This erect, rhizomatous perennial herb can grow up to 3-4 m high, but is mainly grown as an annual. The root system is fibrous and develops cord-like rhizomes that can reach more than 1 m in length, with the apical part of the rhizome forming a fleshy tuber. The leaves are ovate to lanceolate, toothed, pubescent on the lower surface, and 3-20 cm long x 5-8 cm broad. The inflorescence is a pseudanthium, bearing many small yellow tubular fertile flowers surrounded by yellow ray sterile flowers. The fruit is a hairy achene containing a mottled black or brown seed, 5 mm long x 2 mm wide. Jerusalem artichoke is cultivated widely across the temperate zone for its tuber, which is used as a root vegetable. However, it can also be invasive in the Mediterranean region.

What is the sunlight requirement for Jerusalem Artichoke
Jerusalem Artichoke requires abundant, bright and direct light. Placing it less than one foot from a window is the best way to make sure the plant receives enough light to survive and thrive. Depending on your region, however, the current weather can affect the placement of the plant in your home. For example, in some areas the sun may be too direct and intense, so it's best to place it farther away from the window. You may also need to adjust your placement according to the season as the sunlight can change intensity over the course of the year. If you live in a region with significant temperature fluctuations, such as a desert, you may need to place the plant a bit farther away from the window to avoid extreme heat or cold. With some care and attention, your Jerusalem Artichoke will be sure to bring you many years of beauty and enjoyment.

The Jerusalem Artichoke does not necessitate supplementary humidity. Plants primarily absorb water through their roots, rather than their leaves. Hence, the most effective way to supply humidity to your plants is by watering the soil.
How to fertilize Jerusalem Artichoke
The Jerusalem Artichoke should be transferred to a new pot once it has increased in size two-fold, or on an annual basis, whichever occurs earlier. Replacing the soil with fresh potting soil containing all the necessary nutrients, is sufficient enough to support the growth of the plant, thus avoiding the need to use fertilizer. It's important to note that plants derive their energy from the sun and not fertilizer.
