Is it normal for shishigashira leaves to be this small? Every other one I see at garden centers seem to have a lot larger leaves. All 3 the ones I have came from mr. Maple and have small leaves.
Wait a month or so and if they're still that size, you might have a special selection of Shishigashira w/ smaller-than-normal leaves. As it is, my shishis haven't all leafed out yet, so yours may yet embiggen.
If they stay that small, you might have an interesting new variety. Keep it going and take some air layers! I'd be happy to take one or two off your hands.
