I believe arabicum is just not a good rootstock for obesum. Arabicum mostly blooms in the spring and is so slow growing, going dormant, when obesum doesn't need to go dormant. Here's a plant I've had for three years. The top part of the stem is green and growing, but the bottom is brownish, not growing. Hey?
Here's the whole plant! Disappointing for having the buggar for so long.
