About Lady of Shalott Rose
Rosa 'Lady of Shalott' · also called Lady of Shalott, Ausnyson · flowering

Give it full sun and fertile soil; its bushy, arching habit also makes a fine short climber on a pillar.
Preferred mix: Fertile, moisture-retentive but well-drained loam, slightly acidic to neutral (pH 6.0-6.8)
Why lady of shalott rose needs this mix
Lady of Shalott Rose hates drying out, so it wants a mix that stays evenly moist — but it still needs perlite so "moist" never tips into "waterlogged".
- Lady of Shalott Rose comes from damp, shaded forest floors and has fine roots that scorch and brown the moment the rootball dries — the mix has to hold a steady reserve.
- Coir and compost give that reserve, while perlite keeps enough air that the constantly-moist mix does not turn anaerobic.
- Even moisture also keeps its thin leaves from crisping at the edges, which is this plant’s most visible stress signal.
