yes, purple was the initial color with younger flower buds, so seems like we have the same variety
we don't have meyer lemons here, but we have calamondins and kumquats. Not sure if it is self-fertile, and if it isn't---then it is a paternity case between either quat or mondin, or both. And hopefully it is receptive to mr meyer as well
was hoping it was ok with full sun--and am sure it is in cooler regions, but the extreme heat we had yellowed out many of the leaves pretty quickly(as early as june at 110's), so i turned tail and placed it under a trellis.
will probably give it tougher love when it gets a little bigger
