Those Haworthias are sold in the range of $40 to $50 equivalent, while standard ones are marketed in the range of $3 to $5, depending on size. This is from a local grower in my country, not an online purchase, but still too expensive. Money issues left aside, I am reluctant to buy at such high prices (even if the quality justifies that) following my bitter experience with few of the potting mixes which did not meet my expectations. My cultivation method is growing them outside, in the open. Shade, if needed, is provided. There is no frost and they can be left outside. My climate is a warm Mediterranean: No winter frost, but there are heat waves in the summer and erratic but high rainfalls in winter.
So, should I buy them, or would they have any special needs?
