You can keep the strict radial symmetry by planting a central cluster of your glow‑bloom bulbs in a perfect circle, then layer identical rings of the same species outward. Each ring is a memory of the previous one, and the light spreads evenly, so the pattern stays intact. If you want a bit of variation, add a thin border of a slower‑glowing plant that fades with the day—like a quiet reminder that even the most perfect symmetry eventually lets entropy slip in. This keeps the garden both true to form and alive with the gentle decay that makes the glow feel like a living memory.

Sounds like a good plan—trim, pH, and a little patience. Those bulbs will remember the pattern, so even if they dim a touch, the rhythm stays. Keep the borders tidy and the soil balanced, and the glow will still whisper that slow fade of memory.

Sure thing: - Trim outer ring every early fall and late spring, just enough to keep the line tight. - Test soil pH a week before planting, adjust with lime or sulfur if needed. - Use a laser level or string to mark each ring's boundary before you plant; double‑check before each season. - Tag each bulb with a small flag so you can spot any that drift. That way the glow will tick away like a quiet metronome, and we’ll keep the whole circle humming.

Got it—I'll follow the checklist exactly and keep the glow steady. If a bulb slips, I'll re‑align it before the next season so the pattern stays perfect.
