There is a small cactus on the windowsill that only rarely needs water.
Usage tips
Typical features
A cactus is known for its 'Stacheln' (spines/needles). The related verb is 'stechen' (to prick/sting), and the adjective is 'stachelig' (prickly/spiny).
EXAMPLE
Vorsicht, der Kaktus sticht!
Careful, the cactus pricks!
Typical verbs
Certain verbs are typical when talking about caring for a cactus. You only have to 'selten gießen' (water it rarely), because it 'wenig Wasser braucht' (needs little water), and sometimes it can even 'blühen' (bloom).
EXAMPLE
Du darfst den Kaktus nicht zu oft gießen.
You must not water the cactus too often.
Typical context
A cactus is often described as an easy-care 'Zimmerpflanze' (houseplant) that you find on a 'Fensterbank' (windowsill). Its natural habitat is the 'Wüste' (desert).
EXAMPLE
Ich habe mir einen kleinen Kaktus für meine Fensterbank gekauft.
I bought myself a small cactus for my windowsill.

Kaktus vs Aloe
aloe
'die Aloe' and 'der Kaktus' can easily be confused because both plants often have thick, fleshy parts and cope well with dryness. An aloe usually has fleshy leaves and is known, for example, through aloe vera; gel for cosmetics or skincare is also obtained from it. A cactus typically has thick stems and often spines. So not every plant that looks dry or has fleshy parts is a cactus. If you are talking about skincare gel, you usually mean aloe; if you are thinking of a spiny desert plant, 'Kaktus' is more appropriate.
